Hello! When playing sports you should not limit yourself in nutrition, you need to make food more rational, because with physical exertion a lot of calories are spent, for example, based on 1 hour of classes: cross-country skiing or ski jumping - 900, swimming - 720, football or tennis - 600, long walk - 360, measured walking - 90.
In order to calculate the daily need, you need to multiply your weight in kg by 14 and divide by 0.453.
If you want to lose weightthen multiply the desired weight by 14 and divide by 0.453 - the number of calories you should consume per day will be released. Call logging products can be viewed on any site for athletes. As for vitamins, it is better for you to use vitamin-mineral complexes, for example, Supradin.
