He is a proponent of Intermittent Fasting. I've been fasting for 20, 24, 48 and 72 hours - in that order. Other than that I eat one meal a day - some people eat over an 8 or 6 hour period and fast for the rest of the time. The first thing I learned is that you don't need to eat as soon as you get up. Today I haven't yet had my break fast meal.
The other thing is to only eat real food. No processed food at all. No sugar or sweetener - no fruit or fruit juice. Leafy green vegetables, no starches, some protein, but lots of fat - good fats, no vegetable oil except Olive oil. Plenty of avocados, heavy cream, butter, bone broth and fatty meat. He has written a couple of books The Obesity Code: Unlocking the Secrets of Weight Loss being one of them. I'd recommend them.
Following this regime I've come off my diabetic meds - and still become pre-diabetic rather than diabetic, my cholesterol is 6.5% but will come down - Dr Fung explains how burning body fat releases the cholesterol out of the fat cells and into the blood stream to get rid off. I've still got protein in my urine, but again this hopefully will come down.
I'm still testing my blood sugar regularly and I've bought a blood ketone meter so that I can test for those - they're a sign that I'm burning body fat rather than glucose.
I really am a happy bunny. Right time to eat.
