Thanks for posting, This was great info and now I know why I am stuck at a stand still, It's so hard for me to eat that much, I really tried to get up there yesterday. As mfp has me at 1200 cal goal to lose 2 lbs a week, working out 5xs a week. with the 541 extra calories from exercise yesterday, by the end of the day I still had 787 left to go and I was eating when not even hungry... I 'll be trying harder today!

You should definitely be trying to get as close to cal goal as possible, but another issue may be that your loss goal is too high. You are already pretty lean and therefore, your loss goal should probably be at 1/2 lb per week, and certainly no more than 1 lb per week. When you don't have much fat to lose, your body cannot and will not allow that large of a deficit.

Here's another great thread by Banks that helps explain loss goals and deficits. Good luck to you!

I'm wondering, you're saying that you should be eating your exercise calories and eating 1200 calories a day. I would be starving at 1200 a day, I'm starving as it is eating 1500 a day! Noting that I am at 1500 cal/day, should I still be eating my exercise calories? I'm basically in the high end of the healthy weight scale for my height and age and I've been stuck at the same weight since October, but I've found that if I do eat into my exercise calories I gain weight back.

I never said you should eat 1200 calories a day. I don't really ever advise people on a calorie number unless I first have all their information, then I would give my best guess based on that limited information. What I tell people is figure out your maintenance, find a goal that fits your profile, and use that goal (1 lb a week, 2 lbs, 1/2 a lb...etc) exercise calories burned and eaten are a net zero to that deficit, calories burned but not eaten increase the deficit, possibly larger than your body can handle.

Put it this way, think about it logically. If you're at a calorie deficit, and you exercise, then you eat those exercise calories back and gain weight, you're essentially saying that if you didn't exercise you would gain weight at that calorie deficit. How can that be unless you either A) incorrectly figured your statistics on the site, or have been inaccurately reporting your calorie intake, or C) have a medical condition that leads to a change in your metabolic rate, or D) are in starvation mode and your TDEE isn't what you think it is.

think about it like this.

say your maintenance calories are 1800 (just a random number I pulled)

say you're eating at a 500 calorie deficit every day to lose 1 lb per week
that means you're eating 1300 calories a day right?

ok now you exercise for 300 calories, so instead of your body burning 1800 calories that day, it now burned 2100

so if you eat 1300 calories on the day you exercise, your deficit is no longer 500 now it's 800 (2100 - 1300)

but if you did eat those exercise calories, the deficit would be (2100 - 1300) - 300 = 500
the same deficit that you originally planned for.
This is all contingent on my four assumptions above. In other words, you have to be sure your numbers and activity level are correct, you have to be sure you're reporting your calories correctly (people are off more than you'd think), you can't have any underlying medical conditions or on any medication that would disrupt the metabolic rate, and you can't be in starvation mode. Any one of these 4 these issues will change the TDEE (maintenance calories) that you are at, therefore invalidating your deficit number.

Add to that the fact that as humans, we don't fit nicely into any generic formula and a little tweaking is almost always necessary and you have the reason why I never give out a blanket number like 1200. 1200 is simply the number the WHO gave out in the 80s as the average minimum amount of calories FEMALES needed in order to maintain nutrient levels, please note that is the average minimum. Meaning taking all women in the world, averaging their weight and giving you the lowest number that a woman should be eating just to keep from starving over the long term. It's not a very telling number and certainly not something I would ever give out without at least having a specific conversation.

Gotta love logic

Bumping, a lot of confused and questioning people out tonight :laugh:

jnknzxD

I'm confused a bit .. Due to the long words @_@; /Fails at english/ In summery does this mean we eat a decent proportion of foods each meal and not have a bell shape meal plan? [aka, 500 calorie breakfast, 1000 calorie lunch, 200 calorie dinner]

your meal plan doesn't need to be "bell shaped" at all. while I don't advocate large evening meals, I also don't advocate using 1 particular meal for the main calorie intake either, spread out your food through the whole day, let your body have the chance to be consistent.

Thanks for providing this very helpful information:)

I still see many people that are confused or "question" the idea of eating your exercise calories. I wanted to try (as futile as this may turn out to be) to explain the concept in no uncertain terms. I'll save the question of "eating your exercise calories" for the end because I want people to understand WHY we say to do this.

NOTE: I'm not going to use a lot of citation in this, but I don't want people thinking this is my opinion, I have put much careful research into it, most of which is very complicated and took a long time for me to sift through and summarize, and thanks to my chemical engineering backgroud I have the tools to read clinical studies and translate them (somewhat) into more human terms. Some of this information comes from sources I can't forward because they are from pay sites (like New England Journal of Medicine), so you can ask for anything, but I may or may not be able to readilly provide it for you (I can always tell you where to go if you want to though).

I'll break it down into 3 sections.
Section 1 will be our metabolic lifecycle or what happens when we eat and how our body burns fuel.
Section 2 will be what happens when we receive too much, too little, or the wrong kind of fuel.
Section 3 will be the steps needed to bring the body to a healthy state and how the body "thinks" on a sympathetic level (the automatic things our body does like digestion, and energy distribution).

Section 1:
Metabolism, in "layman's" terms, is the process of taking in food, breaking it down into it's components, using the food as fuel and building blocks, and the disposal of the poisons and waste that we ingest as part of it. Metabolism has three overall factors, genetics, nutrition, and environment. So who we are, what we eat, and how we live all contribute to how our metabolism works. You can control 2 of these 3 factors (nutrition, environment).
When you eat food, it is broken down into it's component parts. Protein, vitamins and minerals are transported to the cells that need them to build new cells or repair existing cells. Fats(fatty acid molecules) and carbohydrates are processed (by 2 different means) and either immediately burned or stored for energy. Because the body doesn't store food in a pre-digested state, if you eat more carbs and fat then you need immediately, the body will save them for later in human fat cells (adipose tissue). This is important to realize because even if you eat the correct number of calories in a 24 hour period, if you eat in large quantities infrequently (more then you can burn during the digestion process), your body will still store the extra as fat and eliminate some of the nutrients. (Side note: this is why simple or processed carbs are worse for you compared with complex carbs)

Section 2:
The human body has a set metabolic rate (based on the criteria stated above), this rate can be changed by overall nutritional intake over a period of time, or by increasing activity levels also over a period of time (the exact amount of time for sustained increase in metabolic rates is the subject of some debate, but all studies agree that any increase in activity level will increse the metabolism).
It is important to note that obesity does not drasticly change the level of metabolic process, that means that if you become obese, you don't burn a higher fat percentage just because you have more to burn.
The balance of incomming fuel vs the amount of fuel the body uses is called maintenance calories, or the amount of calories it takes to run your body during a normal day (not including exercise or an extremely lethargic day). The metabolism is a sympathetic process, this means it will utilize lower brain function to control it's level, it also means it can actively "learn" how a body is fitness wise, and knows approximately how much energy it needs to function correctly. It also means automatic reactions will happen when too much or too little fuel is taken in. Too much fuel triggers fat storage, adipose tissue expands and fat is deposited, also free "fat" cells (triglycerides) will circulate in the blood stream (HDL and LDL cholesterol). Too little fuel (again, over an extended period) triggers a survival mode instinct, where the body recognizes the lack of fuel comming in and attempts to minimize body function (slowing down of non-essential organ function) and the maximization of fat storage. It's important to note that this isn't a "switch", the body does this as an ongoing analysis and will adjust the levels of this as needed (there is no "line" between normal and survival mode.).
When you're activity level increases, the human body will perform multiple functions, first, readily available carbohydrates and fats are broken down into fuel, oxydized, and sent directly to the areas that need fuel, next adipose (body) fat is retreived, oxydized, and transported to the areas it is needed for additional fuel, 3rd (and this is important), if fat stores are not easilly reachable (as in people with a healthy BMI where adipose fat is much more scarce), muscle is broken down and used for energy. What people must realize is that the metabolism is an efficiency engine, it will take the best available source of energy, if fat stores are too far away from the systems that need them or too dense to break down quickly, then it won't wait for the slower transfer, it will start breaking down muscle (while still breaking down some of that dense fat as well).

Section 3:
The wonderful part of the human metabolic system is it's ability to adapt and change. Just because your body has entered a certain state, doesn't mean it will stay that way. The downfall to this is that if organs go unused over a long period, they can lose functionality and can take years to fully recover(and sometimes never).
As long as there is no permenant damage to organ function, most people can "re-train" their metabolism to be more efficient by essentially showing it (with the intake of the proper levels and nutritional elements) that it will always have the right amount and types of fuel. This is also known as a healthy nutritional intake.
Going to the extreme one way or the other with fuel consumption will cause the metabolism to react, the more drastic the swing, the more drastic the metabolism reacts to this (for example, a diet that limits fat or cabohydrate intake to very low levels). In general terms, the metabolism will react with predictable results if fuel levels remain in a range it associates with normal fuel levels. If you raise these fuel levels it will react by storing more fat, if you lower these fuel levels, it will react by shutting down processes and storing fat for the "upcomming" famine levels. The most prominent immediate issues (in no particular order) with caloric levels below normal are reduced muscle function, reduction of muscle size and density, liver and kidney failures, increase in LDL (bad) cholesterol levels, and gallstones .


Now onto the question of "Eating your exercise calories"

As I have hinted to throughout this summary of metabolic process, the body has a "range" in which it feels it is receiving the right amount of fuel. The range (as most doctors and research scientists agree) is somewhere between 500 calories above your maintenance calories and 1000 calories below your maintenance calories. This means that the metabolism won't drastically change it's functionality in this range, with that said, this is not exact, it is a range based on averages, you may have a larger or smaller range based on the 3 factors of metabolism stated at the top.
On our website (MyFitnessPal), when you enter your goals, there is a prebuilt deficit designed to keep you in the "normal" metabolic functionality while still burning more calories then you take in. This goal DOES NOT INCLUDE exercise until you enter it. If you enter exercise into your daily plan, the site automatically adjusts your total caloric needs to stay within that normal range (in other words, just put your exercise in, don't worry about doing any additional calculations). Not eating exercise calories can bring you outside that range and (if done over an extended period of days or weeks) will gradually send your body into survival mode, making it harder (but not impossible) to continue to lose weight. The important thing to understand is (and this is REALLY important) the closer you are to your overall healthy weight (again, your metabolism views this a a range, not a specific number) the more prominant the survival mode becomes (remember, we talked about efficiency). This is because as fat becomes scarce, muscle is easier to break down and transport. And thus, the reason why it's harder to lose that "Last 10 pounds".

I really hope this puts a lot of questions to bed. I know people struggle with this issue and I want to make sure they have the straight facts of why we all harp on eating your exercise calories.

Achoooo

Ugh I didn't want to read this because I thought I was going to be told NOT to eat my exercise calories! I went to weight watchers and everyone would talk about how they did NOT eat them and that was their weight loss key (Um none of them maintained any loss though) so anyway I have to eat mine or I feel so shakey and starving, so this topic makes me very happy!

in reality, you can't compare weight watchers to this program because they have different starting points. In order for others to compare any program to this one, first they must understand that MFP puts you at a deficit regardless of exercise. Which means, technically, even if you don't exercise (not that I recommend that), you should still lose weight assuming all your statistics are correct and you have no underlying medical conditions that would hinder weight loss.

good read!!

bonjour24

thanks for this. it helps! i hate the thought of working my bum off then not being able to reward myself with a good (healthy) snack. well, no other diet and exercise regimen has worked for me before (not that the ones i've done have lasted that long), so i guess time will tell if this is the one for me. either way, i'm well into my running now so if i'm a jiggly little porker running a half marathon, so be it!
thanks for doing this. it has made it easier for me to grasp the biological rationale, but i think it still feels a bit alien to be doing it!
