Why do people say it is not possible to be abstinent with food and eating? You can be abstinent when it comes to alcohol and tobacco and other substances. Why can’t you be abstinent with food?
What if you looked at abstinence in the weight loss process as abstinence from eating too much food and abstinence from particularly fattening foods? In another words, you abstain from doing what is making you fat. You still eat, but you abstain from a weight-gaining and weight-maintaining eating pattern.
Try it. Try abstaining from the pattern of eating which was responsible for you gaining too much weight.
