I gained 12kg in a single year, before that i was stuck at 50kg for YEARS, i was 13 in the first picture, now im 17 and i have no idea how this quick gain even happened since my calories intake is basically the same, and i have a very fast metabolism, however my weight tend to fluctuate alot, changing between 63-60kg in just a single week
