I was about 40lbs more than I want to be so 5 weeks ago I thought I'd give it a shot. I know in the end it's all about calories in/calories out but IF isn't as hard as I thought it would be. I decide to try out 20:4. The weekdays are pretty easy but the weekends are a little more challenging(football season) so I've went to 18:6 on Saturdays. The time I eat is between 4-8pm. During fasting I only drink water and coffee. Giving up around 48 ounces of Diet Mountain Dew during the day has probably been the toughest part. So far I've lost about 12lbs. Anyone else try this?
