The best diet for fat loss is one you can maintain over the long term through flexibility, rather than a restrictive diet that excludes your favorite foods.

This advice aligns closely with the current scientific consensus in behavioral nutrition. Meta-analyses, such as those published in the Journal of the American Medical Association (JAMA), confirm that weight loss differences between various diets (low-carb vs. low-fat) are often negligible in the long term, with the determining variable being adherence to the dietary plan. The 'flexible dieting' approach is supported by observational studies showing that rigid dietary restraint is often associated with poorer weight regulation and an increased risk of compulsive eating behaviors. The idea that sustainability takes precedence over a specific method is a fundamental principle recognized in health psychology. There is nothing exaggerated here; the creator avoids miracle promises to focus on human behavior. It is a robust approach that places psychological balance on the same level as a caloric deficit.

What the graded evidence says

Evidence
C

Linked to, not proven to cause.

Effect
rigid vs flexible dieting and disordered-eating symptoms; dieting and later weight/binge outcomes — rigid control associated with higher eating-disorder symptom and BMI scores; flexible control associated with lower; adolescent dieters had higher odds of subsequent overweight and binge eating over 5 years
Measured on
nonobese adult women (cross-sectional); adolescent cohort (Project EAT, 5-year longitudinal)

What’s uncertain

The evidence is observational (associations, not proof), and much of it is in women and adolescents. It doesn't mean quantity and food quality stop mattering, only that rigid restriction is rarely the winning strategy.
