Is 5kg weights enough for losing some chest fat without exercise because my leg is in a cast?

Question

Ive had a foot reconstruction

Answer 1

The only way to lose fat is with cardio 4-6 times a week for average of 45min so stick to walking - it will get you in better shape and also make your leg heal faster.
Healthy diet is a key, though - eat 5-6 times a day, small meals, make healthy choices and never undereat.
weight training only builds muscle - it does not burn fat.
