Far too many people use exercise as a way to eat more. That they can only eat that piece of chocolate or eat at a restaurant if they have done extra exercise. But how about.... eat more so that you have the energy to exercise?
And I know that some people do need to think more about what they eat. I am aware of that fact, but still.... the body needs food and exercise should be enjoyed. Not suffered through just so that you can eat some cake later. How about. ... You eat the piece of cake, enjoy it and then move on and if you have extra energy then use that energy!
A healthy body wants to balance things out... if you eat more your body will naturally give you signs that you have more energy, just like days when you eat less you will feel more tired and less motivated to do things.
Food should be enjoyed and eaten no matter if you exercise or not. And exercise should be enjoyed and you need to eat to exercise. .. not exercise to eat.
You wouldn't expect your car to run on no fuel, so why do you expect that from yourself?
