Any advice of the form "just do X for Y months" is doomed to fail. The right advice is always "do X for the rest of your life".

Many people are overweight because their sense of hunger is poorly calibrated. To overcome that, they need to change something permanently. They need changes in their lives that help them to stay at a healthy weight without being hungry for the rest of their lives.

Agree, but sometimes a radical temporary change can be a catalyst.
