Review Meta Analysis
Effect of reducing total fat intake on body weight: systematic review and meta-analysis of randomised controlled trials and cohort studies.
To investigate the relation between total fat intake and body weight in adults and children. ⋯ There is high quality, consistent evidence that reduction of total fat intake has been achieved in large numbers of both healthy and at risk trial participants over many years. Lower total fat intake leads to small but statistically significant and clinically meaningful, sustained reductions in body weight in adults in studies with baseline fat intakes of 28-43% of energy intake and durations from six months to over eight years. Evidence supports a similar effect in children and young people.
