Calories are not your enemy! You need them for ENERGY.
You need them for FUEL.
You need to have fuel/energy in order for your body to FUNCTION PROPERLY. Don’t overdo it and end up eating 18,000 when you only need about 2,000 (an example, I’m not recommending calorie levels for any of you, so chill out lol) but EAT FOOD. Don’t be afraid of calories. Calories are energy. Energy is what fuels your body to make it through the day, EVEN ON DAYS YOU DON’T WORK OUT.
