Adherence
Individual variability in exercise-induced weight loss is significant, with some individuals losing very little weight ('non-responders') despite high adherence, often due to compensatory increases in energy intake or changes in food preference.
If you exercise consistently but don't lose much weight, don't stop. You are likely still improving your cardiovascular health and body composition. This is common and does not mean the exercise was wasted.
GoodQualifiesHIGH confidence
Evidence indicates that even when the exercise is supervised and closely monitored, there is variability in weight change, both in the direction and magnitude... These data have revived interest in characterising and explaining the variability by focusing on compensatory responses.
Why this rating
Based on specific studies cited (King et al.) showing distinct responder/non-responder groups.

More from this paper
- Acute exercise generally does not increase hunger or energy intake, and chronic supervised exercise in overweight/obese individuals typically fails to trigger compensatory increases in energy intake sufficient to negate the energy deficit, although individual variability exists.Good
- Psychological traits, specifically high Disinhibition and low Restraint, are associated with greater compensatory eating and poorer weight loss outcomes following exercise.Good
