Intermittent fasting, alternate day fasting

Michael Mosley, “Eat, Fast and Live Longer”

Last September I was introduced to intermittent fasting by Michael Mosley who presented an episode of Horizon called, “Eat, Fast and Live Longer“. The idea is simple, for two days each week you only eat 600 calories maximum (500 cals for women) – doing  so will supposedly help you lose weight by switching your body into “maintenance mode” and subsequently, you’ll live longer. Sounds too easy, right?

I’m not a doctor, but I am an avid researched. Tired of reading blog and forum posts, based on opinion and speculation, I decided to dig up some published works to post them here…

My results

I tried the routine for 6 weeks, and lost 7lbs. Nothing spectacular. I did discovered a nasty side effect; my bowel movements became less frequent and my gastric acid production increased – to the point where I was prescribed a generic proton-pump inhibitor. So, for now at least, I won’t be continuing with the regime.

  1. I saw a programme several years ago on eating habits and when of the exponents of calorie restriction was tested he was showing the first signs of osteoporosis. Care to comment?

    1. Hi Marlena, I couldn’t say as I’ve read little that links calorie restriction to osteoporosis. I’ll do some research over the next few weeks…
