Dr. Michael Mosley and his colleagues, James Brown and Sarah Aldred, ride the wave of intermittent fasting popularity with a new review article: Intermittent fasting: a dietary intervention for prevention of diabetes and cardiovascular disease?
LivingTheCRWay congratulates Dr. Mosley. No doubt: His cordial presentation style will contribute to increased interest in calorie restriction overall. This can only be good for public health and may help some overcome obesity and type 2 diabetes.
The question is whether intermittent fasting is good for diabetes and heart disease – as suggested in the review.
Intermittent fasting can be undertaken in several ways but the basic format alternates days of ‘normal’ calorie consumption with days when calorie consumption is severely restricted. This can either be done on an alternating day basis, or more recently a 5:2 strategy has been developed (where 2 days each week are classed as ‘fasting days’ (with <600 calories consumed for men, <500 for women). Importantly, this type of intermittent fasting has been shown to be similarly effective or more effective than continuous modest calorie restriction with regard to weight loss, improved insulin sensitivity and other health biomarkers.
The above statements are unsupported by scientific evidence. Research, cited in the paper, include calorie restriction studies done at Washington University Medical School that did not include intermittent fasting at all. We participated in these studies and, as far as we know, not one study subject used the intermittent fasting approach.
The CR Way does recommend Daily Intermittent Fasting tm, but this is vastly different from on- and-off-day fasting approaches, which may have deleterious effects on the heart and cardiovascular system.
