You can use the Maintenance Plan indefinitely. Some people find that now they feel better they want to release even more unwanted weight. Additional unwanted weight generally occurs when patients tend to be quite toxic and the detoxification process progresses more slowly.
As health continues to be restored (which is the foundational purpose of the Plan), the body generally adjusts and the excess weight is released down the road. It can be challenging to keep from fretting about weight, and you are encouraged to put your focus on rebuilding your health as your primary goal.
Make exercise an important part of any weight loss protocol.
