I have lost about 50lbs in about 4 to 5 months through diet and exorcise but all of a sudden it has became impossible to drop below 240. I am suspecting my metabolism has slowed down due to my crash diet at the beginning, before I learned a good diet. so what do I do I have tried carb cycling and it does not help me right now should I use t3 t4 or some kind of drug to cut the last 20 30lbs because I can maintain weight no problem once I get there
