I've been doing it for about 6 weeks. It's very similar to no-carbing, except that he says whole grains and unpeeled fruit are OK. The book says that fructose especially, and other refined carbs generally, are really bad for you. It's an interesting book, both about the metabolic effects, and about food industry practices and government policy, and their effect on what we eat and our health. You can counter the sugar effect by eating a lot of fibre at the same time, hence unpeeled fruit is OK unless it's really sweet fruit likes grapes or melons, which you should probably avoid. Key things are not to drink any fizzy drinks (even the diet versions, which have the same metabolic effect, apparently), no fruit juice, no smoothies, no dessert, no sugar in/on anything, really keep any other refined carbs to a minimum - like rice once per week or whatever. Milk and dairy carbs are fine, they are metabolised differently.
Anyway, I tend to eat quite a lot of meat and fish, with salad or vegetables, and only drink tea, milk or water. I eat some whole grains: spelt pasta, or whole spelt grains (sounds a bit knit-your-own-lentils in UK I know, but these are normal things to eat in Italy, where I am), brown rice. I don't really eat bread, but wholemeal would be OK. I snack on nuts, plain yoghurt and apples.
I don't let my kids have fizzy drinks, juice, or sweets. Dessert/ice cream only at the weekend. Mix of whole grain and ordinary carbs for them. They still put Nutella on their toast though!
I wasn't trying to lose weight as am quite slim, but I was convinced by the health arguments. I think you would lose weight doing this, if you're carrying a bit of flab. I still have plenty of energy - I run quite a lot and haven't noticed a difference. The really striking thing for me has been my skin though. I look younger, less haggard, and my skin feels all velvety. I've always had problem skin (acne, plus dry patches, plus large pores etc), so I'm really pleased.
If you don't want to buy or read the book, you could look up the author on Youtube. there's a 90 minute lecture there which sets out his argument well and concisely. He is quite focused on the obesity epidemic, but the information is relevant to everybody.
