Tässä yksi tutkimus aiheesta, näyttää että laihdutuksen jälkeen perusaineenvaihdunta jää pitkäksi aikaa "liian" alhaaksi, joten ylläpitääkseen saavutetun painon pitää syödä vähemmän kuin normaalisti kuuluisi. Tästä johtuen lähes aina laihdutetut kilot tulee takaisin vähitellen.
Painon pitäminen kurissa laihdutuksen jälkeen on se isoin haaste laihduttamisessa. Tämän voi vahvistaa lähes kaikki jotka ovat joskus olleet jollain laihdutus dietillä.
To measure long-term changes in resting metabolic rate (RMR) and body composition in participants of The Biggest Loser competition. Body composition was measured by dual energy X-ray absorptiometry and RMR was determined by indirect calorimetry at ...

To the best of our knowledge, this study is the longest follow-up investigation of the changes in metabolic adaptation and body composition subsequent to weight loss and regain. We found that despite substantial weight regain in the 6 years following participation in The Biggest Loser, RMR remained suppressed at the same average level as at the end of the weight loss competition. Mean RMR after 6 years was ~500 kcal/d lower than expected based on the measured body composition changes and the increased age of the subjects.
In conclusion, we found that The Biggest Loser participants regained a substantial amount of their lost weight in the 6 years since the competition, but overall were quite successful at long-term weight loss compared to other lifestyle interventions. Despite substantial weight regain, a large persistent metabolic adaptation was detected. Contrary to expectations, the degree of metabolic adaptation at the end of the competition was not associated with weight regain, but those with greater long-term weight loss also had greater ongoing metabolic slowing. Therefore, long term weight loss requires vigilant combat against persistent metabolic adaptation that acts to proportionally counter ongoing efforts to reduce body weight.
