I am 25 years old, 6'2 weigh at 85 kg atm.
I am using a 90 kg weight after a brutal knee injury and felt my normal weight despite being very obese due to inactivity. However, when my knee recovered I decided to reduce weight and lowered to 80 kg. About two weeks ago I decided to gain weight and add 5 kg in about 14/16 days. Is this too fast? I assume I've been weighing 90 kg before, and eating like this naturally, that this is just a natural transition for my body. Thoughts?
