Having fluctuated in terms of weight over the past few years somewhere between 96kg while occasionally tipping over into 100, never having done a diet in my life, having experienced my mother's death who was 93 I'm feeling that I would like to get to that age too (I am 72), I decided enough was enough and I needed to get back to a reasonable weight. Ideally it would be to get down to just under 80 kilos which would give me a BMI of “normal”. That was my aim. Despite unforeseen interruptions to the diet, I find the Fast800 programme effective and easy to follow, alternating between fasting days and normal eating. I am presently down to 84kg. Other effects (blood pressure, sleeping well…) have been positive too and I have to agree with your own words that you have demystified the science of nutrition while making complex dietary principles accessible. Rather than Ozempic and other medications, wouldn't it be helpful for the National Health to run dietary programmes such as the Fast800?
