How to calculate the burned calories or weight (mass) loss

The number of calories you burn depends on:

Multiply your body weight in kg by the MET (Metabolic equivalent) value by the time of activity, you'll get the approximate energy expent in Kcal according to the person's body weight. In this case, playing tennis at a MET value, burns Kcal/kg x body weight/h.

A 70 kg individual playing tennis for 30 minutes will burn the following:

(METs x 70 kg body weight) x (30 min/60 min) = 255.5 Kcal.

is the value in METs for playing tennis.

To transform the value in calories into pounds just divide the value in calories by 3500. So,

255.5/3500 = 0.07 pound = 1.17 ounces = 33.1 grams of mass. We can't say that it is fat because it could be also muscle.
