If the average person runs for 30 minutes he will burn a Mars Bar or a glass of wine in calories.
This was 17 years ago, I looked fit and healthy but I wasn't. I was 15st-7lbs, (thats 217 pounds!). Just like the dance class I believed because I played football, vigorously, three times a week I was in good shape.
35% of Americans and 25% of Brits are clinically obese and a great many more are fat or overweight. We ALL know why.....we eat too much and don't exercise enough. WRONG!!!!!!! I now way 12st-6lbs (174 pounds). Thats 3st-1lb (or 43 pounds ) LESS. And I have more muscle ( which is supposed to weigh more), so what is going on? Even more scary 90% of Americans believe they eat a healthy diet.
There are two problems with exercising A You feel hungry and B You believe you can now eat because its your reward for all the calories burnt. The result is you eat more than you lost. I personally find that drinking alot of water just after excersise helps and also a healthy protein /carb snack- nuts, fruit, glass of skimmed milk etc seems for me to work best. There is a great deal of research on this but psychologically I tell myself that the fact I have exersised makes no difference to what I would normally eat. Suprisingly long, slow, low intensity training can and does temporarily supress my appetite.
The main thing is we all know excercise is good for us in so many ways that the benefits are endless-just watch out on the eating afterwards.
