It is normal to think that this week of control of your meals is not usual, either because you have committed extra excesses, because you have had more commitments, more work meals, etc. Probably, your social life is like this often during the year, therefore, whatever week you choose to follow up, it could be your usual day to day.
To lose weight by doing sports, it is enough to follow a simple principle: you must burn more calories than you consume daily through food. If you do, you will have a caloric deficit because of which your body must draw on its own reserves of energy. Among these reserves is the fat that you want to get rid of , which means that you will lose weight.
