Exercising after eating a meal can help promote weight loss by boosting hormones that suppress appetite, say UK scientists.
Thanks to these hormones, active people feel less hungry immediately after exercise, and this carries through to their next meal, experiments suggest.
Even when their meals were bigger, sporty people gained fewer calories overall because they burned off more.
The University of Surrey and Imperial College London joint work is published in the Journal of Endocrinology.
Exercise may alter people's appetite to help them lose weight.
According to researcher Dr Denise Robertson:
Twelve volunteers were fed the same breakfast.
An hour later, half of them worked out for an hour on an exercise bike while the other half sat quietly.
Both groups were left for another hour and then allowed to eat as much as they liked.
Exercise guidelines
Unsurprisingly, people who exercised burned more calories than those who sat quietly, 492 kcal compared to 197 kcal.
And when given the chance to eat afterwards, people who had exercised tended to eat more, 913 kcal versus to 762 kcal.
However, when the amount of energy burned during exercise was taken into account, the sporty people took in fewer calories overall - 421 kcal compared to 565 kcal for the inactive group.
And levels of hormones called PYY, GLP-1 and PP, which tell the brain when the stomach is full, increased during and immediately after exercise.
Volunteers also said they felt less hungry during this time.
Researcher Dr Denise Robertson said: "In the past we have been concerned that, although exercise burns energy, people subsequently ate more after working out. This would cancel out any possible weight reduction effects of exercise.
"But our research shows that exercise may alter people's appetite to help them lose weight and prevent further weight gain as part of a healthy, balanced lifestyle."
Experts recommend people do at least 30 minutes of physical activity on five or more days a week.
'Significant contribution'
Dr Ian Campbell, medical director of the charity Weight Concern, said: "This is an interesting study. Patients often report that they feel increased hunger and eat more after exercise.
"What this study shows is that, although total calorific intake is greater, the net result, because of the exercise taken, is a reduction in the net energy balance.
"Dieting is never easy. Increased physical activity is an essential part of any weight management programme, not just to expend more calories but also, as we see here, to help control our appetite too."
Dr John McAvoy, a GP with a special interest in obesity, said the study was a "significant contribution to understanding the complex mechanisms of energy balance".
"It will be of much more interest to the pharmaceutical industry than the general public at this stage, for the simple reason that most people view exercising so soon after eating as akin to putting your fingers down your throat," he added.
"For exercise to contribute to weight control it should be sustainable over the long term and enjoyment remains a critical factor to this end."

How to lose your butt for 2010
Losing weight is on many people’s minds nowadays. This is because there is more information coming in to the media, that highlights the dangers of being obese and of not being vigilant when it comes to diet. In the US alone, over 40% of the population can be considered overweight. This essentially means a BMI of over 25. BMI or body mass index is the standard measure used to gauge one’s weight in relation to their height. It does not really measure, the actually measure of the quantity of fat that is in the body, but it is nevertheless accepted by many medical organizations as the standard way of measuring obesity. Obesity on the other hand is termed as a condition where the body accumulates more fat to the extent that it becomes a health risk. Obesity kills over 400,000 people in the US and costs billions of dollars in lost productivity for workers who have to miss work because of obesity-related medical visits.
There are many ways one can become obese and before we look at how you can lose your butt in 2009, let us examine a few ways in which people gain that butt in the first place. In today’s society, people find themselves so hard pressed for time that they cannot go grocery shopping or cook. Their only option now becomes eating out at a fast food restaurant. Fast food restaurants in turn have mushroomed by the hundreds to cater for this growing number of customers. While they have been trying to reduce the amount of fat they use to fry their food, fast food restaurants nevertheless continue to churn very high-calorie meals and at times the calorie level of some meals can be as high as the entire required calorie intake for the whole day! It is also not unusual nowadays to see whole families eating lunch breakfast and dinner at fast food restaurants. Coupled with a lifestyle again that is too busy to allow for time to exercise, being obese becomes the next logical step for many of these people. There are off course those who have genetic issues that prevent the body metabolism from burning enough calories and so fat is accumulated faster and if these same people live the fast food lifestyle, then they can become obese.
Having a bigger butt is direct result of being obese for most people. Today, many are trying to lose their butt and have become focused on doing so especially for this 2009. There are various ways one can do this.
One way is to exercise. There are many simple exercises and workouts that one can engage in to lose their butt. The first one is walking (yes, walking, something that quite a few of us seem to have fogotten how to do). This is sometimes hard because we live in a society where we need to drive everywhere but when it comes to short distances, walking can go a long way in ensuring that we burn enough fat in our hip, thigh and butt area. Sit ups and simple jogging exercise also help immensely. Swimming is an excellent way to burn of those carbohydrates.

Eat more and Do Less Cardio to Lose that Unwanted Weight
By Isabel
Is the above statement too good to be true? That’s what Rory DeLuca thought. The 42 year old New Jersey resident, husband and busy father of 3 couldn’t believe what I was telling him when he came to see me in January 2006. Like most people, after the holidays, Rory was frustrated with his increased weight and was even more frustrated that his previous “weight loss” efforts were not providing any results. He told me he was trying to eat less and run 4 miles every day, but every time he tried to stick to that routine, his back would hurt because of the running and he would end up starving at the end of the day. You can imagine his surprise when I told him that he would have to eat a lot more and do less cardio to achieve the results he was looking for.
Alternatives to Cardio are Healthy Now, 3 months later, Rory has lost a total of 30 pounds and 9 inches off his body. His back no longer hurts and he is not starving. He eats tons of food all day and exercises less than an hour 5 days a week. So what is the secret to his success? Three very important weight loss principles that we can all incorporate.
1. Rory started strength training 3x’s a week. The key here is Rory was doing the right kind of strength training for his weight loss goal. He was not going from one machine to the next, doing 3 sets of 10 reps on each one. His strength training routine incorporated exercises that used his whole body so his heart rate was up the whole time. Try doing 3 exercises, back to back, using only free weights, stability balls and your own body weight, and you’ll see how quickly your heart rate goes up. No sitting on a bench and chich chatting in this workout. We keep the intensity high the whole time and the workout is complete in 45 minutes.
Incorporating strength training and reducing the amount of aerobic cardiovascular training was integral to his success. The ONLY tissue in the body that burns fat is Muscle. So the more muscle you have in your body, the more fat you’re burning at any given time during the day. The amount of muscle you have in your body also greatly affects your metabolism. So someone with more muscle mass will have a higher metabolism (This is why most men can eat a lot more than women). For example, one pound of muscle in your body requires approximately 50 calories per day. So if I had two people, both weighing 150lbs, but one was comprised of 100lbs of muscle while the other was comprised of 120lbs of muscle, the one with the more muscle mass is burning more calories all day long. That means that this person can eat more during the day and still maintain their weight and will also have an easier time losing weight. Aerobic training does burn calories while you’re doing it, but it does not do anything to increase the amount of muscle in your body, thus it does not help you to continue to burn calories when you’re done
2. Rory only did aerobic cardiovascular exercise using interval training. This concept could encompass a whole article unto itself, but basically, your body becomes accustomed to anything that you expose it to for long periods of time. Aerobic cardiovascular exercise makes your body more efficient at burning fat. But that’s exactly what you don’t want (If your car was more efficient at burning gas, you’d use less of it). Same with your body. If your body becomes efficient at burning fat, you burn less of it for the same amount of work. So instead of burning 200 calories for your 2 mile run, you may burn 150 calories for the same distance in 2 months. So you’ll have to increase the distance and continue to do this, just to burn the same 200 calories. This can eventually turn into running for an hour just to burn the same number of calories! I don’t know about you, but this is exactly what I don’t want to do.
Interval training refers to a series of intense activity separated with short rest periods. You want to make sure that you are constantly changing the intensity of your cardio workout during the whole workout, alternating from high intensity to low intensity. So a typical workout on an elliptical machine would be 5 min warmup, 1 minute at a high intensity (level 9or 10), then 2 minutes at a lower intensity (level 3 or 4). You would repeat this 3 minute round 3 or 4 times, gradually increasing the intensities once you feel like it’s getting easy. Cool down for 5 minutes, and that is a total of 19-22 minutes of cardio, not 1 hour! Keep your body guessing the whole time and it will not become accustomed to the same cardio workout.
3. Rory ate a lot of food all day long. Rory couldn’t believe his meal plan when I laid it out for him. He was going to be eating more than he was currently eating and couldn’t believe this was actually going to help him lose weight. The biggest difference would be what foods he would be choosing. Every meal was comprised of a healthy protein, carbohydrate and good fat. Lots of eggs (whole organic eggs, not whites), poultry, meat, fruits, whole grains, vegetables, olive oil, and raw nuts and nut butters. In order for his body to burn fat, it had to believe it wasn’t starving and the only way to do that was to feed it well.
So what can you do to achieve the same great results?
1. Incorporate both a good strength training routine and interval cardio routine to your workout regimen. Don’t just do one all the time. Your body needs muscle to keep your metabolism high, and it also needs cardio to keep your heart strong, so find a good balance between the two.
2. Incorporate a strength training routine that focuses on whole body movements. No sitting on machines, please. Unless you are rehabilitating an injury, you want to keep your body moving the whole time. What do you think burns more calories, a squat with a shoulder press combination or sitting on a leg press? Just try to squat and raise your arms overhead a few times and you’ll see how quickly your heart rate goes up. Keep your body moving through the whole workout and you’ll be sweating just as much as during your cardio.
3. Eat consistently throughout the day. We’ve all heard it before: Eat five meals a day to lose weight. Well, guess what? It works, as long as those meals incorporate healthy food. Eat a protein with each meal. That is the biggest mistake I see. People are not feeding their muscles with enough protein. Remember, you want to keep your metabolism cranking all day and the best way to do that is to feed your body and to keep your muscle mass high.
Hopefully, this will help you to reduce those countless hours on the treadmill and stop starving yourself to lose a few pounds. I don’t know about you but if eating all day and doing less cardio is going to keep me at a healthy weight and in shape, I say AMEN to that!

A little bit of Exercise Motivation
Many people know how important exercise is as an integral part of their weight loss and health plan but still have a difficult time fitting it into their busy lives.
One possible reason could be that, yes, exercise can be challenging when you first begin your program or you just give yourself the excuse "I just don't have the time."
What I have figured out for myself and for hundreds of my clients that no matter which exercise program they choose, it must be something they enjoy. Especially when it comes to the setting and location.
For me, I have converted the 2nd bedroom of my house into my "home gym".
NO, home gym does not mean I have the most expensive, high tech equipment. To be honest, the only items that make up my home gym are: an exercise ball, 2 adjustable weights, an exercise mat, and an old Spinning bike that I bought used from a local YMCA. That’s it! Nothing expensive or high tech about it.
Many times in the past I have joined gyms and told myself I was going to go. But like many other gym members, I never go! Now, I do really enjoy exercising so why wouldn't I actually use my gym membership?
I figured out that I really love my exercise room. It’s my private time to myself and I don’t have to worry about who else needs the equipment or who’s lurking around the gym. I get an hour to myself and it’s a great way to start my day.
I asked myself if this could possibly be what's stopping many people from exercising. “Is this most people’s problem? Do they not like where they work out so they just don’t want to go?” So it’s really not the actual workout but the environment that they’re in.
Now maybe for you the situation is just the opposite. You don’t like working out in your home and you would much rather get out and be motivated by other healthy people. Whatever the case may be, choose something you enjoy! You will never make a lifestyle change to include exercise on a consistent basis if you don’t enjoy it. Who wants to do something that feels like torture? Not me. I love my morning exercise time and if it felt like torture, I just wouldn’t do it.
My question to you is: What do you have to do to make your workout time enjoyable? Or (heaven forbid) something you actually look forward to? Join an adult sports league? Start your own exercise group? Join a new gym? Set up a home gym? Find a workout partner? The choices are endless.
Try many different options and figure out which activity you would enjoy best and I assure you, exercise never has to be a drag.
