Ive being getting very skinny since I stopped taking Fin. Does anyone know how I can put on weight ? Ive tried eating a lot more food but still cant put on any weight . I use to put on Weight very fast once I eat enough junk food.
Have you tried lifting weights at the Gym? It may sound counterintuitive, but I seem to still gain a bit of weight when I lift. It also stimulates my appetite, so I end up eating a ton.
If that fails, you could always move to America - preferably the South. We have tons of junk food here. 
GOMAD (gallon of milk a day). If you don’t put on weight with that program, you never will
