I haven’t posted on here for about a month, but my inspiration has been rejuvenated to the point that I can promise never to walk out on you again.
Last night I watched a very interesting documentary on the BBC, called Horizon: Eat, Fast and Live Longer. Presented by Michael Mosley, the programme investigated the power of fasting and what effect it has on things like life expectancy, weight loss and the decreasing the growth hormone IGF-1 (high levels of this accelerate ageing and low levels are protective to the body).
The Alternate Day Fasting (ADF) ‘diet’ was investigated amongst other things – where people could (literally) eat whatever they wanted every other day, but ate fewer than 600 calories on the other days. It didn’t matter what you ate on the ‘feed’ days – some people found success eating Big Macs and pizzas on their feed days, equally as much as those who ate more healthy options on those days.
Dr Krista Varady of the University of Illinois commented, “If you were sticking to your fast days, then in terms of cardiovascular disease risk, it didn’t seem to matter if you were eating a high-fat or low-fat diet on your feed (non-fast) days,”. Insane!
Michael Mosely found that ADF was too difficult and impractical, so instead took part in the 5:2 diet (an easier version). It meant eating normally for 5 days a week and eating 500-600 calories each day on the other two. He did the diet for five weeks, lost almost a stone(!) and said, “my blood markers, like IGF-1, glucose and cholesterol, improved. If I can sustain that, it will greatly reduce my risk of contracting age-related diseases like cancer and diabetes.”
If you fancy this diet, you should do so under medical supervision, as it could be dangerous for people who’re diabetic, pregnant or on medication.
