Methodology
How we compare lifestyle with medical treatment.
They are not mutually exclusive
NICE NG246 says medicines for weight management should be used alongside a reduced-calorie diet and increased physical activity. Bariatric pathways also include dietary, behavioural and follow-up care. Our comparison therefore treats lifestyle as a foundation rather than a competing brand.
Why lifestyle gets a lower weight-loss rating
Behavioural programmes can produce clinically meaningful loss, but average losses are generally lower than modern effective anti-obesity medicines or major bariatric surgery. That does not make lifestyle unimportant; it means weight-loss intensity and health-behaviour value are different dimensions.
Why strength scores highly for muscle but not scale loss
Resistance training is important for strength, function and lean-mass preservation. It is not primarily a rapid scale-weight intervention.
Physical activity benchmark
NHS guidance recommends at least 150 minutes of moderate activity per week or 75 minutes vigorous activity, plus strengthening activity on at least 2 days per week for adults.
Ratings are not probabilities
The 0–10 comparison values are editorial decision aids. A 10/10 appetite-support rating does not mean everybody experiences complete appetite suppression.
When we escalate language
The Treatment Finder can personalise context using reported repeated regain, hunger, food noise, cost sensitivity and preference for medical intervention. It still does not prescribe.
