Mt. Mcguire et al., LONG-TERM MAINTENANCE OF WEIGHT-LOSS - DO PEOPLE WHO LOSE WEIGHT THROUGH VARIOUS WEIGHT-LOSS METHODS USE DIFFERENT BEHAVIORS TO MAINTAIN THEIR WEIGHT, International journal of obesity, 22(6), 1998, pp. 572-577
OBJECTIVE: To evaluate whether individuals who lost weight on their ow
n (n = 447), through organized programs (n = 313) or with liquid formu
la (n = 133) would differ in the strategies they used to maintain thei
r weight losses. DESIGN: All subjects were members of the National Wei
ght Control Registry, had lost greater than or equal to 13.6 kg (30 po
unds), and kept it off at least one year (mean weight loss = 30.1 +/-
14.9 kg and mean duration of maintenance = 5.7 +/- 6.9y). RESULTS: Liq
uid Formula users differed from the other two groups on many character
istics; they were more likely to be women, older, heavier, and to have
had a medical disorder prior to weight loss. To maintain their weight
loss, the Liquid Formula group reported greater use of dietary strate
gies (for example, counting calories, limiting the amount of calories
from fat) and higher dietary restraint. Liquid Formula users reported
that weight maintenance was more difficult than losing weight, whereas
individuals who lost weight on their own reported the reverse. The On
Own group reported expending a higher percentage of calories through
strenuous activities such as running and weight lifting, and reported
weighing themselves more frequently to maintain weight loss. Despite t
hese behavioral differences, all three groups are maintaining their we
ight losses similarly by eating a low calorie diet (5792.3 kJ/d and 25
% of daily calories from fat) and engaging in high levels of physical
activity (11847.3 kJ/week). CONCLUSIONS: Despite using different metho
ds to lose weight, individuals who lost weight on their own, through a
n organized program, or with a liquid formula, use similar behavioral
strategies to maintain their weight loss.
