I stumbled across this book when looking for books to study the thought pattern in regards to intermittent fasting and the general "positive" side to doing so. The first 35 pages of this book is mostly a general how-to guide for intermittent fasting for weight loss. Starts by talking about how obesity is becoming a huge problem that is leading to even more problems (diabetes and such) then transfers into the explanation of yoyo dieting with diets that aren't sustainable and a quick gloss over how getting weight off and keeping the weight of is a multifaceted problem. He admits his solution is targeted primarily at reducing insulin levels and he sees no reason why you can't do a low card, low calorie solution mixed with intermittent fasting.
He wants you to reduce your added sugar. He opts for pure maple syrup or honey, which I have read many other people argue against (unless it unaltered honey straight from the hive). So that was interesting. While he says this he does make allowances for the occasional use of sugar, he tells you to stay away as much as possible and keep your intact under a certain number I already forget...and he says dark chocolate is not a terrible thing (thank god!).
Blah blah blah, yada yada yada...stay away from sweetened drinks. Pure tea, pure coffee (okay, you're allowed unsweetened milk), home made broths, water and sparkling water seems to be his only acceptable drinks. Resist processed grains (pasta is my kyptonite for carbs), moderate your protein, increase your good fat intake. Increase your fiber and drink your vinegar (yes you read that right). Eat only when you are hungry (unless you are in a fasting period then he says to 'ride the wave' of hunger).
From what I gathered the 24 hour intermittent fasting is how he is reducing your calories quite severely (as well is taking away your processed grain carbs, sugar and whatever else) as he seems have readers down to a 2-3 meal a day plan with 2-3 24 hour fasting periods plugged in there a week. The last chapter are example charts showing when to fast and when to eat throughout the day along with which recipe to use where. He has 16 and 36 hour fasting charts available as well.
All in all, while I found this diet book highly interesting and do-able for someone with far greater willpower than me, this is not for me. I did like the broth recipes and a few of the meat and salad recipes which I will be trying in the future. But be warned, if you have somewhat limited experience with cheese and spices, you might not know exactly what some of the ingredients are or where to get them.
While 'riding the wave' of hunger for 24-36 hours is not something I want to try while working (I get hangry), I plan on giving the 16 hour intermittent fasting thing a real go once I finish all my research. I will, however, be listening to someone else's advise on how to get there. Fasting AND severely limiting calories, sugars and carbs sounds like a recipe for me to rip some poor person's face off at work. BUT I might be plugging some of his recipes into my repertoire as they sound delicious. Just not all of them at once.
