When do you need 160 kg to lose weight to 100 kg? It will take three months.
From 160 kg to 100 kg in three months, that is, to lose weight, it is more difficult to lose 60 kg. Unless you are very persistent, you can persist in dieting, and it is a cruel diet. Even so, the possibility of rebound is still great, so I suggest you slow down and combine exercise with diet control to lose weight.
