With me, I went on this diet in the 1970s. I only had about 50 pounds to lose, and I did, but there were times when the scale started creeping up again, regaining up to 10 pounds.

That's when I realized I was slipping, sneaking in a few extra carbs and kicking myself out of ketosis.

With me I have to stay on a strict fewer than 20 carbs per day or else I gain. So you eat at a friends and you thin a simple "a bit of this won't hurt" but in reality, it does hurt.

If I want to keep the weight off, I have to stay strictly on-plan and make sure I'm not getting too many carbs or not enough fat.

Of course we are all different.

If you don't want to gain the weight back, keep on plan for life. It gets easier with the passing years to resist the temptations of the past.
