That depends on how long it takes you to lose weight every day. First of all, don't eat too much energy, that is, food and functional drinks. Now, start to eat less slowly. Remember not to overeat, go out to parties, eat and drink freely, and eat more fruits, but don't be full. This is the best. Exercise and jog for 40 minutes, once in the morning and once in the evening. Walk after running 10 minutes. Wipe the fat off your legs. This will not gain muscle. Remember to sit as little as possible, stand more and do more after dinner every day. Two months, I estimate that 10~ 15 kg should be no problem.
