My wife and I have been on 5/2 for almost two years. In three months, I lost 13 lbs, four waist inches and gone from a L shirt to M. I have walked regularly for the last 25 years rather than run after a trail incident and do some weight exercises but not often. My experience on the program has been very positive. As I love both food and drink, fasting two days a week allows me to recover from my occasional excess while at the same time to enjoy my “sins.” I admit to waking up following some fast days and running to have a croissant with my coffee or of thinking about what I’m going to eat when I get up. There is also a great deal of satisfaction at the end of a fast day knowing that I’ve not “sinned” with alcohol or food and looking forward to going to bed early so I can enjoy the next day of normality. My A1C level went down almost a full point to below 6 and I’ve not started diabetic medication that was recommended two years ago by my doctor (and my doc says only to continue what I’m doing). About a year and a half in I went to one fast day a week and have been able to maintain my weight level but I occasionally have to return to twice a week after a period of holiday excess. We plan to stay on the 5/2 as long as we can.
