Fat in Weight Loss Diets - Study
Advice on low-fat diets for obesity.
Overweight and obesity are global health
problems contributing to an ever increasing non-communicable disease burden.
Calorie restriction can achieve short-term weight loss but the weight
loss has not been shown to be sustainable in the long-term. An alternative
approach to calorie restriction is to lower the fat content of the diet.
However, the long-term effects of fat-restricted diets on weight loss
have not been established.
Weight Loss Diets Study - Aim
To assess the effects of advice on low-fat diets as a means of achieving
sustained weight loss, using all available randomised clinical trials.
This review focused primarily on participants who were overweight or clinically
obese and were dieting for the purpose of weight reduction. Since we were
particularly interested in the ability of participants to sustain weight
loss over a longer period of time, we focused on studies of 'free living'
men and women who were given dietary advice rather than provision of food
or money to purchase food.
Weight Loss Diets Study - Method
Weight loss trials were included if they fulfilled the following criteria:
1) they were randomised controlled clinical trials of low-fat diets versus
other weight-reducing diets, 2) the primary purpose of the study was weight
loss, 3) participants were followed for at least six months, 4) the study
participants were adults (18 years or older) who were overweight or obese
(BMI >25 kg/m2) at baseline. Studies including pregnant women or patients
with serious medical conditions were excluded. Two people independently
applied the inclusion criteria to the studies identified. Disagreement
was resolved by discussion or by intervention of a third party. Data were
extracted by three independent reviewers and meta-analysis performed using
a random effects model. Weighted mean differences of weight loss were
calculated for treatment and control groups at 6, 12 and 18 months.
