FAQs: Aging, Healthspan, and Longevity

  1. How can you know that CC diets will increase healthspan?

    Most important is the literature on caloric restriction and intermittent fasting. But the clinical experience of the Hellers is that overweight people tend to get a lot leaner on CC diets, and metabolic parameters associated with metabolic syndrome (blood pressure, triglycerides, HDL) as well as LDL tend to improve markedly. All of these changes point to decidedly lower risk for diabetes, heart disease, and cancer — and these are some of the key disorders that decrease healthspan.


  2. In what way might a CC diet slow the aging process?

    Low insulin levels, maintained by the CC diet, decreases the effective bioactivity of a hormone IGF-I that, in rodent studies has emerged as a key driver of the aging process. More scientific detail →


  3. I am well along in age, is it too late for me to benefit from a CC diet?

    No. Calorie restriction and maintenance of low insulin levels can have a rapid impact on inflammation, oxidative stress, pain perception, growth factor activities, and the process of autophagy which helps to keep the interiors of our cells in optimal working order. Hence – particularly to the extent that a CC diet achieves a measure of calorie restriction – a CC diet initiated even late in life can be expected to have a rapid beneficial impact on: risk of heart attacks, aches and pains, inflammatory disorders, cancer, cognitive function and exercise capacity.
