The simplest and most comfortable thing is to consume energy by not eating carbohydrates. Three meals can be eaten normally, and the only requirement is that you can't eat staple food. You can only eat vegetables, eat more, but don't eat too much, as long as you don't feed yourself. This way, the body will digest the food you eat, and there will be no energy storage, but this method is a bit slow. If it is for the sake of speed, it is good for the landlord to be hard on himself. Very effective. I've been using this method for a month and lost 6 pounds.
