4. Use exercise to burn the fat rather than diets to starve the fat
To lose body fat, there must be a calorie deficit. Such are the laws of
thermodynamics and energy balance. However, there’s more than one way to create a
calorie deficit. One way is to decrease your calorie intake from food. The other is to
increase the amount of calories you burn though exercise.
Of the two ways to create a calorie deficit, burning the calories is the superior
method. This is because large calorie deficits cause muscle loss and trigger the starvation
response. Ironically, most people do the opposite: They slash their calories to starvation
levels and exercise too little or not at all. This causes a decrease in lean body mass and
invokes the starvation mechanism.
