I have watch a few of his YouTube videos and read one of his books. The Diabetic Code.
I’m interested in his claim that you have to fast to get your insulin down and after 36 hours you start using your stored body fat.
Anyone else read his work and claims? what do you think about it?

Because his dietary advice is aimed at T2D's it can be quite helpful. For someone just looking to lose weight, his plan is not as applicable or helpful, IMO.
Fasting is an effective way to reverse insulin resistance along with a LCHF diet. Fung just published something in the BMJ on it.
An article on it:

Therapeutic use of intermittent fasting for people with type 2 diabetes as an alternative to insulin
Summary
This case series documents three patients referred to the Intensive Dietary Management clinic in Toronto, Canada, for insulin-dependent type 2 diabetes. It demonstrates the effectiveness of therapeutic fasting to reverse their insulin resistance, resulting in cessation of insulin therapy while maintaining control of their blood sugars. In addition, these patients were also able to lose significant amounts of body weight, reduce their waist circumference and also reduce their glycated haemoglobin level.

This study says the same thing:

Early Time-Restricted Feeding Improves Insulin Sensitivity, Blood Pressure, and Oxidative Stress Even without Weight Loss in Men with Prediabetes
Summary
Intermittent fasting (IF) improves cardiometabolic health; however, it is unknown whether these effects are due solely to weight loss. We conducted the first supervised controlled feeding trial to test whether IF has benefits independent of weight loss by feeding participants enough food to maintain their weight. Our proof-of-concept study also constitutes the first trial of early time-restricted feeding (eTRF), a form of IF that involves eating early in the day to be in alignment with circadian rhythms in metabolism. Men with prediabetes were randomized to eTRF (6-hr feeding period, with dinner before 3 p.m.) or a control schedule (12-hr feeding period) for 5 weeks and later crossed over to the other schedule. eTRF improved insulin sensitivity, β cell responsiveness, blood pressure, oxidative stress, and appetite. We demonstrate for the first time in humans that eTRF improves some aspects of cardiometabolic health and that IF’s effects are not solely due to weight loss.21 -
I use the very low carb diet (ketogenic) to control my BG and improve insulin sensitivity. I do IF as well, but don't tend to fast for a day - just 16-20 hours.
I like IF for health. I haven't found it to help with weight loss, but that is just my n=1. YMMV

I am waiting for anvilhead to post. He has a real hard on for this guy. Personal? Lol13

I also started with his videos, followed up by reading all 3 of his books. I lost 10 kg in 3 months, following his fasting and diet protocols. BF from 15 % down to 10. He radically altered my perception of diet and nutrition. His isn't the only game in town regarding IF and LCHF but I think he's brilliant. Just my two cents36

I’m not understanding when the posters are saying he’s a quack. What is it about his claims you disagree with?12

I wish he would come along. He does have a treasure trove of info to answer the OP's questions.
OP - He is at odds with about 99% of scientists who work in health and nutrition on a number of his claims.20 -

Well, first insulin is the single cause of weight gain. People forget fat gets stored directly as fat. It does not even need to be converted. People lose and maintain weight gain on any macro level. There is research that a moderate carb diet high in fiber helps with maintenance. I believe that the big difference in high carb vs low carb is protein. Lchf tends to be higher in protein and fiber. Both have high tef and satiety. Does IF do anything? Maybe. We need more research on it. I IF for hunger and satiety issues. I don't get hungry until after I eat. Lchf, higher carbs meals, it does not matter. As far as IDM, I actually contacted them. I was interested in their style for maintenance. When they found out I lost my weight already, they wanted nothing to do with me. Kind of raises red flags to me. Jmho.22 -

Insulin is also the thing that keeps you from starving to death even if you eat massive amounts of food. Doesn't matter how much food goes into your stomach and how much glucose gets into your bloodstream if none of your cells can use it.

Uh yeah. I know this, i was responding to why I think fung is misguided. I deal with type 1 diabetics. When they have really high blood sugars they lose weight. No insulin to provide energy.2 -

Actually, hflc for type 1 diabetics might not be a bad thing. Type 2 diabetics usually have plenty of insulin. The muscle just can't use it properly.0
