From 5:2 to 16:8, do intermittent fasting diets work, and what are the challenges?
Samantha Roberts is three weeks in to a six-week fasting experiment, and she's tired. The research into the effectiveness of fasting diets "really is in the early days," but Dr McMillan is hopeful that her experiment will show the benefits of fasting reach beyond weight loss. Over the six weeks, Samantha lost 3.5 kilograms and Kevin 8.5 kilograms — but Kevin's weight loss is actually "some cause for concern". In particular, Samantha's fasting insulin levels reduced, and her fasting blood glucose levels came down to "the normal category", which means she reduced her risk of developing type 2 diabetes. 'It's not going to be right for everybody' While the results of Dr McMillan's intermittent fasting experiment are promising, she warns that fasting is "not a magic bullet" for weight loss or overall health.
