The Fast 800 Diet: Discover the Ideal Fasting Formula to Shed Pounds, Fight Disease, and Boost Your Overall Health

I think the 5.2 is good , but these eating plans are sustainable, that’s why they work

Dr. Mosley introduces the reader to a number of researchers doing groundbreaking work, usually through interviews. In some of the research, Dr. Mosley becomes a human guinea pig. The reader is kept engaged by his many first-hand stories and his entertaining writing. I'd first purchased the British version of this book last spring. It took me a while to begin to use it. The book doesn't have detailed food lists. Instead, the recommendation is to follow the included recipes or purchase meal replacement shakes (available then in the U.K. and Australia). I wanted to mostly continue eating certain foods, so it took time to figure out how to pare the portions down to 800 calories and still meet nutritional guidelines. Perhaps most problematic for me was the recommendation to get a minimum of 50 to 60 grams of protein per day, with no further guidance. This seemed too low for someone doing daily workouts who wanted to conserve lean mass, so I began a prolonged literature search. Eventually, while looking at ketogenic diets, I found a figure of 1.2 to 1.5 grams per Kg. of lean body weight. In my case this would amount to at least 100 grams per day, or 400 calories. It quickly became apparent to me that consuming this much protein plus a fair amount of vegetables, nuts and seeds would put me far beyond the 800 calorie ceiling. While working out the dietary details, I began another aspect of the diet, Time Restricted Eating. I decided to skip breakfast. After a few days this became so easy that I'd even delay lunch until mid or late afternoon, which amounted to a 16 to 18 hour fast each day. The daily fasts initially reduced my energy level and endurance. My first attempt to do a multi-hour, mostly uphill hike without eating ended after a bit more than an hour, but after a couple of weeks I was able to hike at a normal pace for hours at a time without having eaten. Since I decided not to pare down the calories to 800, my weight loss has been slower than the numbers given in the text. But overall I've been very happy with the results. My plan now is to continue Time Restricted Eating on most days, along with avoiding simple carbohydrates, in the hope that the lost weight is not regained. Dr. Mosley doesn't discuss in detail why almost everyone who diets eventually returns to their "set point." For outstanding insight, and an approach compatible with Dr. Mosley's prescription, I found Jason Fung's "The Obesity Code" to be compelling.

I really like the science behind this diet and that Dr. Mosley explains the numerous studies in easy to understand ways. Very interesting and not boring science. The recipes look delish.

Well, the book is interesting. And all what is saying is well-how good it is to lose weight and to be healthy.It is well written and it is bragging all the time abut being on low keto, not eating sweet fruits, processed food like sausages, carbs and all the time mentioning the goodness of the Mediterranean Diet. On the other hand the recepies are hilarious. Unfortunately the authors of the recepies - Clarke Bailey and Joy Skipper have Skipped on reading the book and just put together some pretentious recepies together coming against all the book is preaching. None of the recepies is Mediterranean-there are at least 8 Chinese, Spanish, Thai and Indian using pasta, sausages and starchy vegs. Ridiculously dissapointing. Waste of money. You are better of googling 400 callorie meal.

Easy reading and packed full of studies/info. Well worth a try if you’re looking for the right program to suit your needs (everyone is different), or just want some info. Recommended.
