Do Carbs at Night Make You Fat?

Convincing enough…

This question has surely crossed your mind at one point or another. Likely, you’ve heard at least one time that carbs at night do indeed make you fat. But does this statement have any scientific credence to it? Is it true that the reason you can’t lose weight is because you like to eat late at night? Let’s try to analyze and answer these questions with science and bad humor.

Where does this seemingly universally accepted statement come from anyway?

   I have no idea. I think most people who cling to this statement have just heard this phrase their whole life so they just stick to it. Those who defend this notion, that eating carbs at night make you fat, will usually point out that since you are about to go to sleep, your metabolism will slow down and all those carbs will be automatically converted to fat. Conversely, they’ll likely argue that if all your carbs are eaten early in the day, you will have the opportunity to magically burn those carbohydrates in your super active daytime lifestyle (that was sarcastic, most of our jobs are probably mostly sedentary, i.e. desk jobs).

So what REALLY happens to our metabolism when we sleep?

   It seems logical to think that while our body’s are still, they’re metabolically inactive. At the very least, our body’s metabolism must be significantly less than it is during the day, right? Well, it’s not that simple. Research done on resting basal metabolic rate compared to sleeping metabolic rate has shown some interesting results. Here are three findings relevant to our discussion:

  1. Averages done on the resting metabolic rate (RMR) and sleeping metabolic rate (SMR) proved to be SIMILAR and NOT SIGNIFICANTLY DIFFERENT. [5,7]
  2. Sleeping metabolic rate was directly correlated with body mass index. Obese individuals had a SMR LOWER than their RMR. Non-obese individuals had a SMR HIGHER than their RMR. So if you’re not obese, you’re actually burning more calorie while sleeping than you are playing Playstation. [7]
  3. Exercise INCREASES sleeping metabolic rate significantly, which leads to greater fat oxidation (breaking down fat for energy). [3]

So, it doesn’t really seem like our bodies are metabolically inactive during sleep after all. In fact, we might even be burning more calories during sleep than we are at rest during the day.

What about the idea of using morning carbs for energy?

   I touched on this idea in my post on intermittent fasting, but let’s take another look. Having carbohydrates in the morning for energy is more subjective than we are lead to believe. Many people, including myself, are big supporters of the idea that being in a fasted state in the morning does not equal a decrease in performance. Speaking from personal experience, I have attended class, studied, and performed my day to day activities just fine in a fasted state (note: I would consume black coffee on those days). With that said, there are certain occasions in which I did notice a decrease in performance without my morning carbohydrates for fuel: examinations and weight lifting. I wouldn’t recommend anyone about to embark on a tough examination to go in on an empty stomach. It makes sense too, during an examination we need to think more critically than usual and need mental endurance to brace ourselves to complete the examination without collapsing. Several studies have shown the benefits of having breakfast on school performance as well (granted, they’re usually performed on children and adolescents) [2]. The ingestion of carbohydrates for athletic performance is a lot more physiologically obvious and heavily supported by evidence [8].

So do carbs at night make me fat or not?

   The reason you may be having a hard time losing weight is REALLY unlikely due to you eating carbs at night. A randomized controlled study taken place over 6 months was done to give a good answer to this question. This study put one group of police officers in an experimental group of subjects having majority of their carbohydrates (approximately 80%) at night and the control group having majority of their carbohydrates throughout the day. Both groups consumed the same amount of calories, proteins, carbohydrates, and fat each day. After 6 months, the experimental group (who consumed their carbs at night) lost significantly more weight and body fat then the control group [6]. So yeah, feel free to reference that study to the next person about to choke you out for grabbing a slice of toast at 10pm.

2-Chainz…I mean terrible music…I mean 2 random thoughts…

  • I’m not here to say that eating carbohydrates at night is an amazing idea, it’s just not a terrible one. In fact, eating RIGHT before going to sleep is probably not a great idea and will probably leave you feeling bloated in the morning. Give your food some time to digest before hitting the sack (while typing those last three words, I just realized what an awkward phrase that is to reference going to sleep. Seriously, who thought of that?).
  • Carbs at night may improve sleep. Again, not too late, but this study looked at carbohydrates consumed 4 hours before sleep and showed improvement in sleep. [1]
  • Sorry for the late post.
  • That’s 3 random thoughts, bro. You’re ability to count in sequential numerical order is as good as 2-chainz’ ability to make music.

Conclusion

   If you will notice, my conclusions are usually pretty similar. Super restrictive rules that are spread around by society and taken as facts, are usually far from factual. In an all too familiar pattern, the big picture, which is the most important aspect to weight loss, is skipped over. Are you taking in more calories than you are consuming? Are you balancing out your macronutrients in such a fashion to optimize weight loss? The best take away you could take from this article is to go back to putting the focus on the TOTAL quantity/quality of calories consumed in a day. Don’t put the blame on your lack or weight loss on having to eating dinner later than your friends are. Instead, focus on exercising more, eating less, eating higher quality/nutrient dense foods, and indulging on the occasional slice of chocolate cake to maintain your sanity.

Intermittent Fasting: A Helpful Way to Finally Eat Less

There’s no wrong time of the day to eat pancakes

So you’ve been reading the latest FNDfitness blog posts. Following his page on Facebook. Watching his weird faces when he’s singing on youtube. You are really starting to understand that the key to losing weight is not just eating “healthy” but eating less. You’ve been eating a more moderately sized breakfast, decent sized lunch, snacking on Doritos less, but you still can’t lose weight. Even more frustrating is that you know what the problem is, dinner. Everyday you come home at 10pm from school and mom has a giant, delicious, calorie filled meal ready for you. As we all know, mom’s cooking beats self control every time.

This was my personal example of how I was struggling to eat less. Yours may not be exactly the same predicament but, none the less, you face the same problem…you love food too much and just can’t eat less! Well, the solution to my problem was implementing intermittent fasting into my life. Let’s learn more about this nutritional strategy (not diet) and see if it can help you!


 

WHAT IT IS…
-An adjustment to the traditional pattern of eating. Most of us in the world are used to the traditional breakfast at 8am, lunch at 1pm, dinner at 6pm schedule. Intermittent fasting has you eating all of your meals in an 8 hour window and be in a fasted state for 16. For example, you will have your first meal of the day at 1pm and final meal before 9pm. Noncaloric beverages, like water, or those with negligible calories, like black coffee, are permitted throughout the whole day.
*NOTE: There are different variants of intermittent fasting (ex. 24 hour fasts every 3 days). This post is going to talk about the 8 hour feeding/16 hour fasting style.*

HOW IT HELPS…
-There are several mechanisms of which intermittent fasting has claims of aiding in fat loss. The two most common are greater insulin sensitivity and an increased releasing of fat burning hormones. Insulin sensitivity is a good thing; it means your insulin cells are working efficiently to remove glucose from the blood stream and put it to good use. The opposite of being insulin sensitive is insulin resistant (for example, people who are type 2 diabetic are insulin resistant). The increased release of fat burning hormones (which are growth hormones) assist in muscle building and fat burning…kind of self explanatory on how that would be beneficial for fat loss [4]. Besides these two factors, intermittent fasting leads you to eat LESS. Now that you know that you have a smaller window in the day to eat your calories, the idea is that you end up eating less for the whole day.

SKIP BREAKFAST? LOL OK FNDFITNESS, I’LL CHOOSE PANCAKES INSTEAD…
-Here we tackle potentially the biggest hurdle for people to try intermittent fasting, skipping breakfast. You’ve basically heard your whole life that skipping breakfast is one step away from committing a crime. Well, as we learned from my last post, breakfast does not magically “kick start” your metabolism; they proved this in a study as well [1]. What about the claims that insulin sensitivity is the highest during the morning (physiologically this is actually true, by the way)? Also, don’t I need to use all of the energy from my breakfast for fuel throughout the day? Unfortunately, for the breakfast fan club, these ideas, which sound nice on the surface, when put to the tests did not give any definite superiority to having breakfast. A study here experimented with two groups: breakfast eaters and breakfast skippers. The result was no significant difference in weight loss [2].

-I’m not saying breakfast is the enemy, I love waffles in the morning more than anyone (actually, I could probably eat waffles anytime) . You could even send me links to studies in which those that ate breakfast lost more weight than those that didn’t because of greater appetite suppression. That’s all fine and dandy, but I’m here to tell you it’s an association, not a causation. Having breakfast may help you lose weight if it makes you less hungry and eat less throughout the day. For others, like myself, they may end up eating the same amount regardless of the inclusion of a big, healthy, and filling breakfast. The point I’m trying to get across is you don’t HAVE to eat breakfast to lose weight.

WHAT IS GHRELIN?
-Ghrelin is basically the hunger hormone; it’s what gets released when you become hungry. To adapt intermittent fasting into your routine, you’re going to have to trick ghrelin. Ghrelin is a complicated and not completely well understood hormone but we know it works off of your circadian rhythm. Circadian rhythm is basically your daily routine and your body’s adaptation to it. If you go to sleep at 10pm every single day, it’s your circadian rhythm and the corresponding physiological mechanisms that kick in and makes you tired at approximately that time. Similarly, ghrelin works with your circadian rhythm; for example, if you eat breakfast every day at 10am everyday, ghrelin is likely being secreted at that time. It’s not a coincidence you get hungry the same time every day (assuming you follow a relatively routine schedule). So how do we trick ghrelin? Well, when you start doing intermittent fasting, you will be hungry in the beginning. This is your adjustment phase, but after a while (anywhere from a few days to a week) that morning hunger should go away. No longer is ghrelin accustomed to being released in the morning since you’re not having breakfast anymore.

EXERCISING IN A FASTED STATE…
-Supporters of intermittent fasting will often point to the benefits of completing a high intensity cardio workout in a fasted state. The claim is since you’re in a fasted state your body will go straight to its fat stores as energy which will thus enhance fat loss. As incredible as this sounds, a recent study was carried out over 4 weeks with one group exercising from a fasted state and the other group after a meal. They were given matching customized meal plans to ensure both groups were in an equal caloric deficit. The results of the study showed both groups lost a significant amount of weight but there was no significant difference between the two groups [6]. The bottom line is that we really need longer studies to better analyze the long term effects of fasted cardio. The best idea would be to implement exercise into your lifestyle whether or not it’s in the fasted stage.

DOES ALL OF THIS APPLY FOR WOMEN?
-It’s a little bit more complicated. Women go through a monthly menstrual cycle which can cause hormonal imbalances which may complicate intermittent fasting for them. Unfortunately, very sparse studies have been done on human females on intermittent fasting. Those that have, have mostly been on animal subjects. To further complicate things, the results were very confusing. Results showed an increase in bad cholesterol, an increase in good cholesterol, a little bit of weight loss, a decrease in blood pressure, and more hunger [7]. Confused by these results? Yeah, me too. Long story short, we don’t have enough data from studies to make really any kind of judgement. The best way to find out if intermittent fasting is right for you, you might have to just give it a try and see how it feels for you.

WHO SHOULD NOT DO INTERMITTENT FASTING?
-Intermittent fasting is not for everyone and certain conditions dictate it necessary you speak with your physician before embarking on this lifestyle change. Those conditions include, but are not limited to, diabetes, pregnancy, and more. If you have any kind of health condition(s), it’s always a good idea to consult with your healthcare professional first.

IN SUMMARY & RANDOM THOUGHTS:

  • Intermittent fasting is a strategy to help you lose weight for potentially a few different reasons: greater release of growth/fat burning hormones; increased insulin sensitivity; and by minimizing your window of opportunity to eat, thus leading you to eat less.
  • You aren’t going to die from skipping breakfast. At first it may be tough, but your body will adjust. If you skip breakfast and remain productive throughout the day and have stopped yourself from eating too much, well then that’s awesome. If after a week you still feel that you need that morning bagel to get you through the day, then maybe intermittent fasting isn’t for you, and that’s okay.
  • Intermittent fasting may be a little more challenging for women due to their monthly menstrual cycle. Studies have shown very mixed results. Best idea might be to just give it a try and see how it works for you.
  • Intermittent fasting MAY work for you. Intermittent fasting MAY NOT work for you. You can get in shape by using it. You can get in shape by not using it. What’s the most important thing? Hitting those macronutrients and micronutrients, sound familiar? The foundation of your health stays the same, getting in your macronutrients in an adequate amount appropriate for your lifestyle and taking in enough micronutrients to optimize body functions and overall health.
  • I used intermittent fasting for about 6 months and lost a decent amount of fat I was struggling to lose through other ways. My problem was every day I was going to have a heavy dinner because it’s my favorite meal, my mom makes awesome food, and it was one thing I had to look forward to everyday. I would routinely eat breakfast but really didn’t enjoy it, I just ate it because I thought I had to. After starting intermittent fasting I skipped the breakfast and would have my first meal of the day at approximately 1pm. I noticed that I no longer felt hungry randomly throughout the day and felt much more controlled in my eating. I didn’t notice any lack of energy/productivity throughout the day despite sitting through hours of lectures and studying. I did notice a decreased performance in the gym, so the days I wanted to exercise I would eat breakfast before my lifts.
  • Now, I usually save intermittent fasting for a day after I consume a lot of extra calories the day prior. This gives me some extra time to digest the ridiculous amount of food I had ate the day before and helps me make sure I don’t splurge on back to back days.
  • Your 8 hour gap does not have to be from 1:00PM to 9:00PM. It can be any 8 hour window of the day.
  • I love caramel, it should be on every desert ever made.

6 Meals or 3 Meals, What’s Better?

Wow, this is one big subject to tackle. The discussion of meal frequency is an intriguing one because there’s a lot of recent research going into this subject matter. Perhaps, the best way to start out by tackling this topic is to look at one of the most common myths out there…does eating more meals equal more fat loss and/or increase my metabolism?

No, not necessarily. To understand this myth, let’s first learn the word of the day- thermogenic effect of food (TEF). Thermogenic effect of food refers to the energy used by the body when processing food intake. Here’s how the science works. *For the sake of explanation, we are going to use arbitrary numbers for the following example*

Say your diet consists of only apples; let’s say one apple has 100 calories and the thermogenic effect used by your body to process that apple burns 10 calories upon consumption.
-In scenario 1, I eat 2 apples 3 times a day (6 apples for those counting at home). Through wolfram, I discovered that 6 apples (in one day) x 10 calories (of thermogenic energy used per banana)=60 calories burned through TEF for that day.
-In scenario 2, I eat 1 apple 6 times a day. This scenario would be following the logic for more frequent/smaller portioned meals. Let’s see how much we boost our metabolism with this method. I’m no math major, but I still ate 6 apples for the day x 10 calories (of thermogenic energy used per apple)=60 calories burned through TEF for that day. Wow, no difference. Science wins.


Here’s the science which puts everything together. A few brilliant, well known and respected nutritionists got together and completed a meta-analysis and pooled the data from studies on meal frequency. They went through literally ALL english language journals and searched for studies on the topic which fit certain inclusion criteria. Inclusion criteria basically helps them narrow down certain criteria for the studies to better include the studies in their analysis which hold more weight. For example, they only included studies which had a duration of at least 2 weeks. Here was their conclusion:

“Moreover, the small difference in magnitude of effect between frequencies suggests that any potential benefits, if they exist at all, have limited practical significance. Given that adherence is of primary concern with respect to nutritional prescription, the number of daily meals consumed should come down to personal choice if one’s goal is to improve body composition. There is emerging evidence that an irregular eating pattern can have negative metabolic effects, at least in the absence of formal exercise. This gives credence to the hypothesis that it may be beneficial to stay consistent with a given meal frequency throughout the week.” [1]

So what does all this mean? Well, it goes back to the original concept of IIFYM, have your meal timings accommodate into your schedule. It has not been shown that more frequent meals helps you lose any extra weight, so if you like eating only 3 meals a day, continue to do it. If you are more comfortable eating several smaller meals, that’s fine too. In either case, if you’re goal is to lose weight, you just need to eat/drink less calories. Now, we can dive deeper into this subject and talk about the lack of studies with meal frequencies and high protein intake. We could also talk about the benefit recent studies have shown of having protein throughout the day as opposed to consuming it in one or two bulk sittings. And we WILL talk about these topics…but in future posts. For now the take away should be to debunk the myth that you NEED to have smaller/frequent meals throughout the day to lose weight. What you NEED to do to lose weight is be in a caloric deficit (more calories out than in). The most efficient way to do that? Count your calories/macros to hit your target numbers so that you are at a caloric deficit and exercise more often.

How to Start Tracking Your Macros Today!

The lonely corner…where only the counters of macros reside
  1. Click here and plug in your information to get your results of your total daily net allowance of calories, fats, protein, and carbs. For now, just use the recommended grams per body weight that are provided.
  2. Download the “My Fitness Pal” app on your smart phone or tablet. You can even go on their website, www.myfitnesspal.com, if you wish to track your macros on a desktop/laptop. Make your free account and fill in your information. After you plug in your information, the application will automatically create its own macros for you, but we are going to use the macros we got from step 1.
  3. Go into settings and go into goals. Now, you can input the calories you recorded from step 1. Click on carbohydrates and change the percentages of each macro (carbs, protein, and fat) so that the grams match the “grams per day” you received from step 1.
  4. Give yourself a pat on the back.

Congrats, you have finished the first step in counting your macros and are one step closer to better understanding food/nutrition. My next blog post will help you in understanding your girlfriend better. Just kidding. I’m as single as that dude that comes to Starbucks and all of the workers know his name and usual drink; the same guy who then proceeds to sit in his usual corner table alone for several hours. Loser. Here are some basic FAQ’s about counting your macros to help clear up any initial confusion.

Q: Some of the food items on my fitness pal go by weight and I don’t have a food scale. Are you sending me a food scale?
A: No. Buy one. Or you can guesstimate. A slab of meat the size and thickness of your palm is approximately 6 ounces, give or take. You can also use google to search your inquiry, you’ll probably find someone else with the same question. Hopefully you have a least measuring cups at home, you’ll kind of need that. This is not an exact science but as you continue to track your macros you will get better at it, trust me.

Q: Sometimes I get multiple results for the same search item. Which is the correct one?
A: Well, one is not necessarily correct or going to exactly match what you are eating. A good rule of thumb is to do a rough average of the results you pull. Here’s an example. You’re eating homemade pizza and it’s about the size of a normal slice. You put in “pizza” and see the calories ranging from 150-300. Pick somewhere in the middle. Usually for a plain slice, I would give it about 250 calories, give or take. This problem brings us to the next question…

Q: Do I round up or down?
A: When counting calories people almost always have a tendency to underreport what they have eaten throughout the day. Therefore, I think it’s always a better idea to go with the higher number when you’re not sure where to round to.

Q: So, I went over my calories for the day? Is it all over for me?
A: No, don’t be silly. Obviously, the goal is to get as close to your target as you can, but there will be some days you go under and some days you go over. So what do you do if you go over 300 calories on bagel Tuesday at work? Try to be 300 calories under your goal the next day. You do not get fat or gain weight from one bad meal or one bad day. This is a process that happens over time. So if your goal was to lose weight and your total calories for the day was supposed to be at 2000 but you take in 2300 over the period of a week or two…then yes, you will gain weight. This strategy of allocating your calories and going over/under occasionally really holds the key to be flexible with your diet.

Q: I’ve actually seen you at Starbucks, sitting in the corner alone, for several hours at a time. Are you sure you weren’t talking about yourself?
A: Um…”I’m just here so I won’t get fined.”

5 Things You NEED to Know About IIFYM (If It Fits Your Macros)

Our new favorite word--Moderation
Our new favorite word–Cookies…I mean Moderation

Macros, macros, macros. If you’ve read the basic introduction to the concept of “If It Fits Your Macros”, you hopefully have a general idea of what IIFYM is. Allow me now to try to convey the impact of how understanding what the meaning of IIFYM can have for your understanding of basic nutrition.

  1. IIFYM is NOT a diet, it’s science.
    IIFYM can be described as a method, technique, or just an understanding that the most important aspect in reaching your desired body composition (whether it’s weight loss, weight gain, or maintenance) is reaching your total daily macronutrient intake targets.
  2. IIFYM does NOT mean you can eat whatever you want.
    So, IIFYM gets a reputation of being a diet in which people eat whatever the hell they want as long as they “reach their total daily macronutrient intake targets”. This is stupid. No one is saying to eat enough pop-tarts and debbie cakes to hit your target marcronutrient/micronutrients. Majority of your total food intake (around 90% is a good benchmark according to fitness/nutrition guru Alan Aragon) should be coming from whole/minimally processed foods and the remaining can be from your secret stash of candy under your bed [1].
  3. Almost all diets incorporate one of the main underlying principles of IIFYM.
    That underlying principle is not some big secret, by the way, it’s the most basic understanding of weight loss: to lose weight you need to be at a caloric deficit. In layman terms, to lose weight you need to burn more calories than you take in. Think of a balance scale, on the left side we have “calories in” and on the right side “calories out”. On the left side we have all of the calories you consume through food/beverages. On the right side, “calories out”, the calories you burn throughout the day. We know calories are burnt by exercising and being active but calories are also burned at rest (we call this basal metabolic rate or BMR). When the left side of the scale, calories in, is greater than the ride side (so, more energy in verses out) we gain weight. When it’s the other way around, more energy out than in, we lose weight. All diets out there probably will help you lose weight in the short-term because they restrict a certain type of food group (like forbidding all carbohydrates) so you’re bound to significantly reduce your “calories in”. IIFYM sets those daily targets at the appropriate amount so that you are fixed to burn more calories than you are going to be taking in. Difference is, you do not have to drop-kick your roommate for bringing in bread to the house.
  4. It does require you to count calories…but not forever.
    Like we said earlier, the only way you can achieve weight loss is by using up more energy than you are taking in. So, when most people go on a diet and start eating “healthy” they usually naturally tend to eat less empty calories, more nutrient dense foods, and exercise more. When they start to lose weight it’s because of that magic “energy in verses energy out” formula. The problem with this awesome sounding plan is not that it doesn’t work, because it does, it just usually is not sustainable. Most people get tired of eating salads and vegetable juice three times a day, everyday. Worry not, in comes tracking calories. No longer is it a guessing game if I’m eating too many calories, too little, or just enough. Now you can squeeze in that Snickers bar, ice cream cone, or Snickers flavored ice cream bar into your day. The difference now is that since you have been counting your calories the whole day you’ll know if those two scoops of ice cream kept you under your total daily calories; or maybe if you only had room for more one scoop before going over your total allowed calories. After counting your calories for a while, you gain a great understanding of the macronutrient composition of a lot of foods. Do you have to do this counting for the rest of your life? Not quite. After counting your calories for a while, you gain a really good understanding of the macronutrient composition of foods. When you reach this level of mastery, you’ll be surprised how well you can almost count your macros by guesstimating for the day.
  5. Don’t forget your micronutrients.
    We keep talking about macronutrients, but what about micronutrients? Do people who follow IIFYM even care about vitamins/minerals? Why, certainly we do. As mentioned already, heavy majority of your dietary intake of the day should be from whole/minimally processed foods (aka not pop-tarts). This includes getting several servings of vegetables, fruits, nuts, and other food items needed to fulfill the proper vitamin intake needed for healthy human function.
