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 ...

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.

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...

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. http://nessoblogs.blogspot.com...

You could simply be Anorexic but that .. Doesn't sound right. Don't think you would be on here if so. Hm ... Exercise does not increase you appetite to eat.

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 say if you did a 30-60 minute run from 6-8miles an hour, then you should eat something l...

But say if you did a 30-60 minute run from 6-8miles an hour, then you should eat something like a recovery bar or drink (power bar makes great ones) or a two bike ride, the same thing.
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

"For me, intense exercise is a period of exercise that's 45 minutes to an hour that generally involves me running at speeds in excess of 20 km/h for half that time at least."

"After I've done intense exercise, I don't feel hungry at all, mainly because I feel pretty sick or burn out."

My thought
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 yo...

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?

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....

you feel hungery because you use the engery (ATP) that food gives you to be able to perform exercise. after you are done exercising you body needs more ATP. and the only way to get ATP is to be well nurished.

because you think more of wat youre doin than food
