Dang. At my heaviest I was literally 100 lbs lighter before I lost 70 lbs.   today I am 102 lbs. My advise to you is to go on a water fast. When you feel you are about to faint, have tea and a small packet of yogurt and maybe some crackers. When I was at my heaviest, starving myself made me lose weight fast. Also treadmilling. Go for long walks if you can’t treadmill yet. No more chips, ice cream, cheese, fast food. Good luck.
