It depends on the type of exercise you do.
Fitness swimming is a good example. Swimming is a notoriously poor method of exercise for inducing weight loss. Swimming sessions do not result in the same degree of weight loss that other exercise sessions of comparable caloric expenditure do; they also don't affect the appetite the same way.

Often, after a hard swim workout in the morning, you'll still be hungry for a big breakfast, but after a morning run you'll be less likely to feel hungry until later in the day.

In the case of swimming, body temperature may drop after prolonged exposure to cold water. This can stimulate hunger for a period of time after exercise. But running and forms of exercise that elevate body temperature tend to suppress the appetite after exercise.
Exercise intensity also affects appetite levels. The few studies that have closely examine the relationship between exercise intensity and food intake note that the higher the intensity of exercise, the more severe the degree of appetite suppression, and the longer duration of reduced food intake.

Of course, appetite levels gradually return to normal, but they don't seem to increase quite enough to compensate for the energy expended during exercise. Long-term energy intake-eating a lot for a long period of time-does not seem to increase over time, which suggests that daily bouts of intense exercise shift the energy balance, and are an effective strategy in weight control.

Anyone serious about getting healthy knows that exercise is a vital part of the equation, but have you found that working out also brings on a serious appetite?

Most of us would say that exercise does make you hungry, but others believe that doing really intense exercise can take your appetite away.

People often feel nauseous following intense exercise and this is because there is build up of acids within the body as a result of metabolism, and these acids have a direct affect on the brain, which makes us feel quite sick. If you're into intense exercise, don't fight the nausea by eating. Instead, keep your fluids up — dehydration is not a place you want to go.

I get that all the time after a hard work out or big race.
I know I feel sick after and don't want to eat food or just not hungry. But you have to eat something after a big work out 10-30minute right after you've finished. I depends on the kind of workout, If you do for example, 30minute of walking, with little hill, you shouldn't be hungry after or just eat sometime very small like a couple prezles or crackers.

But what ever kind of work out you should have a little snack before it and a snack after even if you don't feel hungry.
I know how you feel... I race a lot.
If you just can't eat whole food after a work out try a RECORERY drink (POWER BAR or CLIFF BAR are good ones) they are about $2.00 each and can in pack

I used to have that problem. I'd exercise and then eat twice as much as I normally ate. But then I came up with a solution. If you eat a substantial meal 30 mins before exercise then you don't feel hungry at all. For me its come to the point where I only need to eat a banana beforehand and I don't feel hungry at all after a workout. It is definitely possible to train your body not to feel hungry after exercise, just like its possible to train your body not to feel hungry every 20 minutes. The key is to restrain yourself. And then after a few difficult days you settle right into it and it comes naturally. such thing. A possible reason for that is: After exercising, you may feel hungrier - so if you eat right after exercising, chances are you may eat more... which leads to less weight loss. But I normally don't feel hungry right after exercising - I lose my appetite, in fact. I think it's got to do with the endorphin production... because exercising makes your body produce endorphin, which make you feel happy and (to some extent) satisfied, so it kind of blocks out your hunger.

The next few excerpts I discover online that may share light...each excerpts have a link for more information.

QUESTION: I don't usually feel hungry after I exercise, even though I exercise first thing in the morning. Why is that? Should I eat before I work out?

DR. HART: If you eat before a workout you may experience cramping and nausea. This is because exercise causes the blood vessels in your digestive system to narrow, while blood vessels to your muscles become wider. This allows the blood to flow to the muscles you are working, supplying them with more oxygen and glucose (sugar) for work and energy, rather than to the digestive tract. After vigorous exercise, you are less likely to be hungry because your stomach has a smaller blood supply and is less ready to handle an influx of food.

QUESTION: How much water do I need when I exercise?

DR. HART: Our bodies are approximately 60% water, so even at rest, we need plenty of fluid. When you exercise, you lose water through sweat. To keep up with these losses and avoid dehydration, drink 2 to 3 cups of water within the hour before you exercise, a half to a full cup every 10 to 15 minutes during the workout, and at least 1 to 2 cups within 30 minutes afterwards. This is as necessary in cold weather as it is in warm weather.

Here are a couple of ways to tell if you need to drink more water:
Weigh yourself before exercise and immediately after. Drink 2 cups of water for every pound you lost during the workout.
Check the color of your urine. It should be pale yellow or clear. If it is dark or bright yellow, you are dehydrated and should drink.

I suggest eating protein to help with the hunger. Are you a vegetarian?

Salmon and other fish are really good choices. Try to balance your protein and try not to eat the same foods all the time.
find that just getting enough protein isn't enough. I also need fat and fiber. It really needs to be *balanced*. I wish it were easier! Nuts are better than carbs for holding me over, but not great on their own. It's kinda wacky, and tough figuring out what is the key for each of us. Don't be too worried about fat content (if it's healthy fat). If you keep portions small, it's all good.

Also be mindful of eating when you're not actually hungry. I fall into spurts of that, and I find that it's either when I'm bored or restless, or not drinking enough liquid.
Why do I feel hungry when I'm exercising, but when I go home I'm not hungry anymore?

Moderate exercise by itself does not increase your appetite unless you have exercised too hard or are on a quick weight loss diet and your glycogen stores are depleted. Glycogen is the stored form of glucose in your muscles and liver. You only have about 1500 to 1800 calories of stored glycogen. When glycogen is depleted, your body has to turn to protein in muscles and organs to supply glucose. Depending on the time of your last meal before exercising, your blood sugar may be low. In which case, your body is telling you to eat.

Moderate exercise helps in suppressing appetite and increasing your metabolic rate for up to 15 hours after exercise. A gland in your brain called the hypothalamus is responsible for secreting a hormone, which inhibits hunger. Exercise helps stimulate this gland to produce more of this hormone. Moderate exercise that would produce this beneficial effect would be 60 minutes of exercise, three to five times per week. Possibly, by the time you complete your exercising the suppression of your appetite has started.

Because your body is producing chemicals in your brain that not only make you feel good but less hungry too, endorphins I believe they're called. Believe it or not exercise is the best appetite suppressant (spelling?) out there and its free, no side effects unless you injure yourself working out, and man do you feel good. So after you exercise try having a protien water, good for replenishing and its not heavy, eat later a few hours after you workout....

when you exersise your moving your body profusely and your stomach is expanding and shrinking, also your stomach feels that it's strong. but when your hungry your stomach feels weak, so you eat food to make it feel strong again. but exersising cancels out your stomach feeling weak so you dont FEEL hungry. ( just a word of advice,you should still eat 3 meals a day just so you won't become melnourished).

When you are occupied with something seriously you don't feel hungry at all.to the reverse when you don't have anyhting to do, sometimes you feel hungry before the usual time. Our body system is controlled by the brain and the nervous system. The hormones and the nervous system make us feel hungry There may be some physical or psychological reasons for not feeling hungry which can be treated by a physician or a psychiatrist.

Many people believe that engaging in exercise leaves you feeling hungry. Some take it further claiming that you end up eating more - thus negating any calorie deficit from the exercise.

Many people believe that engaging in exercise leaves you feeling hungry. Some take it further claiming that you end up eating more - thus negating any calorie deficit from the exercise.

So what is the truth?

Researchers in the UK have concluded that exercise does indeed make you hungry - but the overall result will still give you a calorie deficit.

Researchers took 6 men and 6 women through the following steps.

1. Ate the same breakfast.
2. Wait for an hour.
3. One group did 60 minutes of stationary cycling (at 65% max heart rate). The other group did nothing.
4. Wait for an hour.
5. Everyone enjoyed an all-you-can-eat buffet.

The Results
The exercising group consumed 913 Calories at the buffet. The non-exercising group ate 762 Calories. However, during exercise, the first group burned 492 Calories compared to 197 Calories.

The net result: the exercisers ultimately took in around 144 less Calories.

Note that during and immediately after exercise volunteers reported they felt less hungry - and the appetite suppressing hormones PYY, GLP-1 and PP were increased.If you don't mind, please answer my survey questions

The post workout meal (the meal you eat after a workout) is probably the most important meal of the day for anyone who is into nutrition and fitness. However, in a lot of cases this importance also leads to confusion. Maybe it's because of the many ready-made shakes available. Maybe it's the trouble with fitting it in with the rest of your diet. Maybe it's just generally not knowing whether you should even eat anything after you've worked out. Whatever it is, something about it confuses people.

The truth is, once you understand the basics of what nutrients your body needs and doesn't need after your workout, and what the best sources are to get this nutrition from, the post workout meal will probably become the most simple and quick meal of your day.

What you should and should NOT eat after a workout.

Simply put, aside from water (which you should already know you need) your post workout meal needs to contain 2 things, and it needs to not contain 1. You should be eating protein and carbs. You should NOT be eating fat. More on the protein and carbs you need a little later. First, let's start with a quick explanation of why you shouldn't eat fat after a workout.

Many times throughout this website I explain why fat is NOT a bad thing (when it's the "good" fat) and why it is an important part of everyone's diet. However, there just happens to be a certain time when fat (good or bad) wouldn't be good to eat. This of course is in the post workout meal. Simply put, fat slows down digestion. In this case, it would be slowing down the digestion of protein and carbs. This, as you're about to find out, is the exact opposite of what you want to happen.

At this point you should really have just 3 questions about your post workout meal:

1 - How soon should I eat it?
2 - How much protein and how many carbs should I eat?
3 - What foods should the protein and carbs be coming from?

Hey, what a coincidence, here comes the answers to all of those questions...

How long after my workout should I eat my post workout meal?

Soon... really soon. As soon as you can. I don't mean put-down-the-dumbbells-and-start-eating. It doesn't need to be quite that soon. However, there is this "window of time" that exists after your workout during which it would be the most beneficial for your body to receive it's post workout nutrition. Typically you'd want to try to get this meal into your body within 1 hour. If possible, within 30 minutes would be even better. I personally have my post workout meal about 5-10 minutes after my workout. What's that you say? How can I do it so fast if I'm at the gym? Don't worry, more on that later.

Post Workout Protein

Now that you know that time is of the essence when it comes to your post workout meal, this part is going to make a whole lot of sense. See, eating this meal soon after a workout is important, but just because you are putting the food into your body quickly doesn't actually mean the food is being digested and used by your body equally as quick. While egg whites, chicken and tuna fish are fine sources of protein that I personally eat daily, they aren't the ideal type of protein for the meal after your workout.

These foods are whole foods, and the protein in whole foods digest pretty slowly. You may have eaten a high protein food in your post workout meal, but by the time the protein is digested and finally ready to be used by your body, a whole lot of time would have passed. This is why the ideal source of protein to eat after your workout is a whey protein powder mixed with some type of liquid thus creating a whey protein shake.

A whey protein shake will be digested by your body much quicker than a whole food because it will be a liquid. And, not to mention, whey protein is the fastest digesting protein there is. This is what makes whey protein pretty much the official choice of most people as their post workout meal protein source. Most people try to consume anywhere from 20-50 grams of protein at this time. I'd say 30 is probably a good number to shoot for.

As for the whey protein powder itself, I personally use Designer Whey Protein Powder.

Post Workout Carbs

Yeah yeah yeah. "Carbs are bad! Carbs are the devil! I am scared to death of carbs! Get them away from me!!" Settle down. First of all, they aren't so bad. Secondly, after your workout they are actually an extremely important part of your post workout nutrition. Carbs will be used by your body to restore muscle glycogen. If your post workout meal doesn't contain carbs, your body may actually instead break down muscle tissue for this same purpose. That would be a bad thing. Carbs also create an insulin spike which helps to move nutrients into your muscle tissue quicker.

So, now that you know you need them after a workout, what kind do you need? Well, you know all about good carbs and bad carbs by now, right? Funny enough, this is actually the only time when "good carbs" and "bad carbs" switch roles. This doesn't mean start eating cookies, this just means that typical good carbs (whole wheat bread, brown rice, etc) contain fiber, and fiber slows down their digestion. This is actually what makes them "good" any other time of the day. But by now you know the post workout meal is all about speed. And when it comes to speed, simple carbs beat complex carbs.

A food like a baked potato is an okay choice for a carb source after a workout. However, just like protein, whole foods in general aren't really the most ideal choice at this time. This is where a little something called dextrose comes in. Dextrose is not a supplement... it's actually just a type of sugar. I know, I'm basically saying you should eat sugar. While that would be insane any other time of the day, your post workout meal is the one exception.

Along with whey protein, dextrose has also become almost an official choice for a post workout carb. Most people usually consume between 40-80 grams of carbs at this time from dextrose. I think 50-60 is probably a more average number to shoot for. As far as dextrose goes, I personally use NOW Foods Dextrose.

My Post Workout Meal

To finish this article up, here is what I do. Before I leave for the gym, I put everything I need inside of a shaker bottle. A shaker bottle is just a plastic cup with a cover and some type of "blending" piece inside. You just put something in it, add water, and shake it for about 5-10 seconds. It is simple and extremely convenient for your post workout meal. I put in the whey protein powder, dextrose, and 5 grams of L-Glutamine (more about L-Glutamine) and take a bottle of water with me.

After my workout I get into my car, open the shaker bottle, pour in the water, shake for 5-10 seconds and drink on the ride home. The whole process takes less than a minute and the whole "meal" is finished in a matter of minutes if I take my time. There you have it... quick, easy, convenient and contains the best sources of everything my body requires post workout.
