How can we reduce overweight, alleviate chronic diseases, and stay healthy longer? The key to this is autophagy. This natural mechanism in the body breaks down harmful cellular components and recycles them. This process eliminates toxins, protects cells from stress, and stimulates fat burning. James Clement, a scientist, genomic researcher, and initiator of a unique global research study on centenarians, demonstrates how you can activate and control autophagy through intermittent fasting, reduced protein intake, and a ketogenic diet, thereby empowering your body to slow down the aging process and prevent diseases—from diabetes to dementia. He provides deep insights into how our bodies work, explains which diets are beneficial for our cells, and offers an easy-to-implement program that allows everyone to benefit from the positive effects of autophagy—for a longer and healthier life.
