My husband uses IF quite successfully. He was never heavy, but had just a little extra around the middle. Using IF alone (with regular exercise, we both work out regularly), he went from 212 to 195. He is 6' 4" He is really slim and trim now at age 55. I tried it, but found that it wasn't hunger so much that bothered me, as it was an increase in stomach acid. I can amend the diet and do a 600 calorie day, but I need a little food in the gut just to keep digestion problems at bay. (I have a mild hiatal hernia, which is probably the source of the problem). As a result of this experiment, I stick with an Adkins-type diet all week long, with a once-a-week treat of a couple of good chocolates during the week. And, one of the week days will be very low cal but not a full fast.

Time to lower the goal, I guess!
