I have been doing intermittent fasting for 14 months. I watched all of Dr. Jason Fung’s videos on Diet Doctor and was inspired. I fast 19 hours every day and eat in a 5-hour window. I’ve lost 42 lbs and 8.5 inches in my waist. Thank you, DietDoctor.com and Dr. Fung!

I’ve been doing IF for over nine months, mostly 20:4 and 24 hr. fasts, however I have only lost 10 lbs in this entire time. I do primarily low carb, with high vegetables and meats. I’ve recently switched to alternate day fasting, but am still not seeing the astounding success that so many others have had. I do have hypertension and chronic lung disease, but my numbers have not improved, either.
