I beg to differ. Fasting IS fat burning. Eating a low calorie diet puts your metabolism in low resource mode. Eating nothing, hence fasting, switches your metabolic engine to burning stored fart which releases ketone bodies for fuel. It is actually very healing and therapeutic. I think 44 days was overdoing it. It might have been a case of diminishing returns. But I have always maintained my health and weight through regular fasts. Start small, and build up to 24, 48, 72 hours over time. Your body will thank you.
