eli5:Why do people struggle to keep weight off after losing it?

1.97K views

I love watching weightloss challenges, so I watch people go through these crazy transformations but often times after I hear that the participants will gain a significant portion, if not all, of the weight back. Why is that? Is it diet? Biology?

On one of those weight loss shows the participants have a trainer trainer and dietitian monitoring their progress and carefully prescribing their diet and exercise. All that change is external, applied to the participant.

Once the show is over, they leave. The participant is left to their own devices, and nobody will tell them otherwise. Often, they go back to whatever they were doing before the show, which is usually why they were overweight in the first place.

The only way to prevent that from happening is for the participant to change their lifestyle on their own and internalize whatever they learned, and continue to act as they were on the show without the trainer or dietitian guiding them. It has to be an internal change they chose for themselves.
