Four Months, Fifty Pounds

Trying to actually get in shape for the first time ever, i carry my weight well but to be "healthy" i need to drop at least forty-five pounds. I'm am not looking to be thin in any way. Just healthy. I'm 20 years old in 30 days. Hopefully dropping my weight from 210 to 160 in 120 days. This is just a way to help me stick to it.
