Few years back my doctor was concerned about my blood pressure and recommended I lose weight. I asked how and he after the expected recommendations about eating healthier and exercising he added, "but whatever you do, don't fast." I asked why and he said it doesn't really work better long-term but increases the risk of other health problems especially gall-stones. A year later I weighed 10% less and my blood pressure was normal again. I ate less salt, fat, and sugar plus took-up soccer again. Years later I'm still not chonky again.
