How does nutrition affect physical fitness?

Diet and exercise: Eat properly before and after exercise

If you do sport on an empty stomach, you cannot train at full intensity and therefore use less energy.

One thing is clear: in order to lose weight, you have to achieve a calorie deficit - so it is important to burn more energy than to consume. But starvation is not the solution, because for long-term success it is crucial not to let your energy level drop. Above all, you should never exercise on an empty stomach, otherwise you cannot train at full intensity and therefore use less energy. You also run the risk of hypoglycaemia. In order to lose weight in a healthy and sustainable way, it is therefore important to meet your energy needs with the right foods. In any case, this includes plenty of vegetables. 200 calories from broccoli are always better than 200 calories from currywurst. Micronutrients such as magnesium and zinc should also be consumed in abundance. Both are found in oatmeal and lentils, for example. Whether a lot of carbohydrates and little fat or little carbohydrates and a lot of fat help you lose weight is scientifically controversial. One thing is certain: fat is a basic building block of the human nervous system and various processes in our organism do not function without fats. Therefore, one should not completely do without fat. However, it is healthier to rely primarily on unsaturated fatty acids from, for example, rapeseed oil, avocado or nuts and to reduce the consumption of saturated fatty acids from sausage, butter or cream.
