Intermittent fasting may hold the key to longevity
In the recent BBC documentary “Eat, Fast and Live Longer,” Michael Mosley fasted for three days and four nights. The result? Halved levels of IGF-1, slashing his risk for age-related disease. His blood glucose levels also fell, indicating improved sensitivity to insulin and lessened risk of developing diabetes. As is typical, after returning to his normal diet Mosley’s IGF-1 levels rose to what they were before. To maintain lower levels of the hormone, Mosley adopted the practice of intermittent fasting, taking up what is known as the 5:2 diet. Followers of the 5:2 diet eat whatever they want five days a week and about 500 calories twice a week. Amazingly, following this simple formula is known to lower blood pressure, HDL cholesterol and blood lipids and sustain weight loss no matter what kind of food is consumed. After five weeks on the diet, Mosley lost almost 15 pounds.
Additional promising research on mice suggests that intermittent fasting protects against mental illnesses including Alzheimer’s, Parkinson’s and dementia.
Two simpler dietary interventions also promise some dampening of IGF-1: lowering protein intake, which for most people is higher than is optimal, and refraining from milk. Hormone-rich milk contains an abundance of IGF-1 and is known to contribute to the risk of cancer, particularly fatal prostate cancer.
