In fact, whether a person's weight is increased or decreased is determined by two factors, one is the consumption of calories and the other is the intake of calories. If the consumption is greater than the intake, the natural weight will decrease; if the intake is greater than the consumption, the accumulated natural weight of body heat will increase. Therefore, reasonable calorie consumption and intake is particularly important. From these two aspects, exercise and diet can scientifically calculate their daily calorie changes, so that they can clearly know why they are thin or fat.
As for the specific calculation method, I suggest that you can choose to use a mobile phone app that can calculate calories (I feel good when using it), and it is best to have an exercise or diet plan, so that the effect will be more helpful to lose weight.
