Quality of dietary fat intake and body weight and obesity in a Mediterranean population: secondary analyses within the PREDIMED trial
A moderately high-fat Mediterranean diet does not promote weight gain. This study aimed to investigate the association between dietary intake of specific types of fat and obesity and body weight. A prospective cohort study was performed using data of 6942 participants in the PREDIMED trial, with...

| description | A moderately high-fat Mediterranean diet does not promote weight gain. This study
aimed to investigate the association between dietary intake of specific types of fat and obesity and
body weight. A prospective cohort study was performed using data of 6942 participants in the
PREDIMED trial, with yearly repeated validated food-frequency questionnaires, and anthropometric
outcomes (median follow-up: 4.8 years). The effects of replacing dietary fat subtypes for one another,proteins or carbohydrates were estimated using generalized estimating equations substitution models.
Replacement of 5% energy from saturated fatty acids (SFA) with monounsaturated fatty acids (MUFA)
or polyunsaturated fatty acids (PUFA) resulted in weight changes of −0.38 kg (95% Confidece Iinterval
(CI): −0.69, −0.07), and −0.51 kg (95% CI: −0.81, −0.20), respectively. Replacing proteins with MUFA
or PUFA decreased the odds of becoming obese. Estimates for the daily substitution of one portion of
red meat with white meat, oily fish or white fish showed weight changes up to −0.87 kg. Increasing
the intake of unsaturated fatty acids at the expense of SFA, proteins, and carbohydrates showed
beneficial effects on body weight and obesity. It may therefore be desirable to encourage high-quality
fat diets like the Mediterranean diet instead of restricting total fat intake. |
