So, I heard that the 5:2 fasting helps speed up your metabolism. Is this true? If yes, how?

    From The Fast Diet FAQ:

    Will [fasting] put me into starvation mode?
    This is another very common myth. The initial response of your body to a reduction in calories is to increase your metabolic rate. This is because, in our hunter-gatherer past, survival in times of food shortage would have depended on our becoming more active, going out to hunt and look for food. Only under conditions of extreme calorie deprivation, when we have been for weeks without enough food and our body fat has fallen dramatically does the body go into “starvation mode”. IF is not the same as crash dieting. Starvation mode does not happen if you cut your calories for a day!!

    Yes, intermittent fasting is said speed up the metabolism. If you Google "intermittent fasting" and "metabolism" I am sure you will find more articles then you have time to read and you will be able to find some that explains in detail how the fasting effects metabolism. Or maybe someone in the groups has a detailed explanation of how intermittent fasting causes the metabolism to speed up?

    Also this link to a documentary on 5:2 fasting that @flumi_f posted would explain a lot as well:
