Anyone see that documentary a while back (might have been a a Horizon programme) about diet and exercise.
The presenter was looking into the latest science on diet and exercise.
One of the most remarkable parts was the increase in lifespan of rats on a restricted calorie diet, the average lifespan increase was 40%.
Back on topic......
The other revelation, to me any way, was fasting. The presenter did about a month (IIRC) of fasting 2 days a week, and very short duration exercise at maximum heart rate i.e. 3 minutes per week.
The results were astounding, and contradict the current accepted approach to diet and exercise.
well worth a watch if you can find it.
