Reducing calories so that a person stays 15 percent below his ideal weight is the goal. All important nutrients, vitamins, minerals, etc., are still consumed. One hundred-thirteen is the oldest scientifically recorded age for any human. Reports of Hunzas, Ecuadorians, Turks and Russians living to 120 and more have never been verified. For the past several centuries, life expectancy has gradually increased.
Some critics complain that undernutrition requires following a starvation diet.
It becomes a question of personal priorities, what YOU consider more important, overeating, smoking, drinking, plus rich desserts, OR improving vision, hearing, physical well-being, mental clarity and sexual vigor into an advanced age. Dr. Walford's personal undernutrition program includes fasting 2 days. He runs 8 to 10 miles weekly, swims' and does weight lifting exercises for his general health and muscle tone. Dr. Walford's book explains that an important part of aging is caused by a process whereby the immunity system becomes unbalanced. Undernutrition prevents that from happening.
