Low Fat Diet & Weight - Study
Low-fat diet: effect on anthropometrics,
blood pressure, glucose, and insulin in older women.
Low Fat Diet Study - Aim
The Women's Health Trial: Feasibility Study in Minority Populations (WHT:
FSMP) documented that a low-fat diet was associated with a reduced fat
intake in older women of diverse ethnic backgrounds. The purpose of the
current study was to examine the effect of the low-fat diet on anthropometric
and biochemical variables.
Low Fat Diet Study - Design
Randomized clinical trial in 2,208 postmenopausal women, 50 to 79 years
of age.
Low Fat Diet Study - Results
The decrease in fat intake correlated directly with a decrease in body
weight. After 6 months, the intervention group had an average weight loss
of 1.8 kg. Body mass index decreased 0.7 kg/m2. Waist circumference decreased
1.8 cm. All of these changes were statistically significant, compared
to changes in the control group. Changes in systolic and diastolic blood
pressures (BP) occurred in the intervention group. The decrease in systolic
BP reached statistical significance, relative to the control group. Decreases
in plasma glucose were small in the intervention group, although there
was a trend for difference from the control group. Decreases in serum
insulin levels were small in the intervention group, although there was,
again, a trend for difference from the control group.
Low Fat Diet Study - Conclusions
In older White, Black, and Hispanic women, a long-term low-fat dietary
intervention was accompanied by modest, but statistically significant,
decreases in body weight and anthropometric indices, without any particular
attempt being made to reduce calories. Changes in glucose and insulin
were small. The long-term biological significance of the glucose and insulin
changes is unknown.
