The odds of success
Approximately 1% of persons with a body mass index over 30 maintain weight loss long term.
99% of people with Medical Class 1 Obesity will gain the weight they lost over time. Medical Obesity, in the context of everyday people, could be seen as ‘a few kg to lose’ - ie, 68kg at 150cm, 77kg at 160cm
This is a factual but initially shocking statistic.
“During a maximum of 9 years’ follow-up, 1283 men and 2245 women attained normal body weight. In simple obesity (body mass index = 30.0–34.9 kg/m2), the annual probability of attaining normal weight was 1 in 210 for men and 1 in 124 for women, increasing to 1 in 1290 for men and 1 in 677 for women with morbid obesity (body mass index = 40.0–44.9 kg/m2).”

United Kingdom used a decade’s worth of digital health records for 278,982 people — 129,194 men and 149,788 women
This review describes our current understanding of the biological, behavioral, and environmental factors driving this near-ubiquitous body weight trajectory and the implications for long-term weight management.
