במחקר הבא אנשים אכלו מאוזן, פעם אחת בארוחה אחת ביום, פעם שניה ב3 ארוחות ביום (והפוך) במשך 8 שבועות כל פעם. מדדו נתונים שקשורים לבריאות, ואת הרכב הגוף.
בקבוצות שאכלו פעם ביום, נרשמה ירידה במסת השומן ושמירה על מסה רזה בעוד שבקבוצות של ה3 ארוחות ביום מסת השומן והמסה הרזה לא השתנו. מעבר לכך, אצל האנשים שאכלו פעם ביום נרשמה ירידה ברמות הקורטיזול.
Subjects’ weight and body fat mass were lowered (1.4 and 2.1
kg, respectively) after consumption of the 1 meal/d diet but not
after consumption of the 3 meals/d diet.
המחקר:
A controlled trial of reduced meal frequency without caloric
restriction in healthy, normal-weight, middle-aged adults1–
Background:
Although consumption of 3 meals/d is the most common
pattern of eating in industrialized countries, a scientific rationale
for this meal frequency with respect to optimal health is lacking.
A diet with less meal frequency can improve the health and extend
the lifespan of laboratory animals, but its effect on humans has never
been tested.
Objective:
A pilot study was conducted to establish the effects of a
reduced-meal-frequency diet on health indicators in healthy,
normal-weight adults.
Design:
The study was a randomized crossover design with two
8-wk treatment periods. During the treatment periods, subjects consumed
all of the calories needed for weight maintenance in either 3
meals/d or 1 meal/d.
Results:
Subjects who completed the study maintained their body
weight within 2 kg of their initial weight throughout the 6-mo period.
There were no significant effects of meal frequency on heart rate,
body temperature, or most of the blood variables measured. However,
when consuming 1 meal/d, subjects had a significant increase
in hunger; a significant modification of body composition, including
reductions in fat mass; significant increases in blood pressure and in
total, LDL-, and HDL-cholesterol concentrations; and a significant
decrease in concentrations of cortisol.
Conclusions:
Normal-weight subjects are able to comply with a 1
meal/d diet. When meal frequency is decreased without a reduction
in overall calorie intake, modest changes occur in body composition,
some cardiovascular disease risk factors, and hematologic variables.
