The three drivers of regain
Metabolic adaptation: TDEE drops more than weight loss predicts, so "maintenance" is actually a mild surplus.
Elevated ghrelin and reduced leptin after weight loss push hunger up for months.
The diet was structurally unsustainable — foods you don't want to eat for years.
What works for keeping it off
Regular weigh-ins (weekly average). Strength training. A protein-forward diet you'd eat even without goals. Steps most days.
