While many of us feel destined for cellulite, saddle bags, and belly fat, or worry about the long line of Alzheimer’s, cancer, and heart disease in our families, the scientific reality is that 90 percent of the signs of aging and disease are caused by lifestyle choices, not genes. There are five key factors that lead to accelerated aging: muscle, brain, hormone, gut, and toxic fat. Dr. Gottfried’s seven-week Younger Protocol addresses these factors with an accessible, practical plan to increase our life spans, change the way we age, and remain healthy and energetic for all our days.
