So just indulge once in a while then go back to the diet. This winter when I would go to a holiday dinner or supper party, I would enjoy what was there, but the next day eat very little, drink tea and a little soup and in 2 days my weight would be back to the preindulgence weight.
A good philosophy generally, but that doesn’t work well with ketogenic diets. Once you get knocked out of ketosis, it takes time to go back into it.
