Totally has to be DNP. It takes 4 days before I feel it. The bad news is that eating an extra 2k calories for me cancels out what it can burn. You cannot burn 50 lbs in a week. 50 lbs of fat is 204 kWh of energy. The average oven requires 2 kWh of energy every hour of operation. Which means the lard on this fat sack of shit could run an oven for 100 hours straight. Raising body temperature by a few degrees is dangerous. So without dying, losing 50 lbs will take a while.
