Background:

The National Weight Control Registry (NWCR) was established to examine characteristics of successful weight loss maintainers. This study compares the diet and behavioral characteristics and weight regain trajectories of NWCR members with differing physical activity (PA) levels at baseline.

Methods:

Participants (n = 3591) were divided into 4 levels of self-reported PA at registry entry (< 1000, 1000 to < 2250, 2250 to < 3500, and ≥ 3500 kcals/week). We compared self-reported energy intake (EI), macronutrient composition, eating behaviors (dietary restraint, hunger, and disinhibition), weight loss maintenance strategies, and 3 year weight regain between these 4 activity groups.

Results:

Those with the highest PA at registry entry had lost the most weight, and reported lower fat intake, more dietary restraint, and greater reliance on several specific dietary strategies to maintain weight loss. Those in the lowest PA category maintained weight loss despite low levels of PA and without greater reliance on dietary strategies. There were no differences in odds of weight regain at year 3 between PA groups.

Conclusions:

These findings suggest that there is not a “one size fits all strategy” for successful weight loss maintenance and that weight loss maintenance may require the use of more strategies by some individuals than others.

The aim of this review is to provide a scientific update on the current guidelines for both health and weight management. There has been confusion among health professionals as to which physical activity guidelines should be used to help various specific populations adopt more active lifestyles. We first review the history of the physical activity guidelines. Using the physical activity guidelines in clinical practice is also explored. We also describe common barriers to physical that overweight individuals report and we discuss when it is appropriate for a health care professional to seek a referral from an exercise scientist to help sedentary adults increase their levels of activity. It is important for individuals who care for overweight patients and sedentary adults to understand the current physical guidelines and how these guidelines can be worked into clinical practice.

The resting metabolic rate (RMR) and thermic effect of a meal (TEM) were determined in 13 low-energy intake (LOW) and 11 adequate-energy intake (ADQ) male endurance athletes. The LOW athletes reported eating 1,490 kcal·day-1 less than the ADQ group, while the activity level of both groups was similar. Despite these differences, both groups had a similar fat-free mass (FFM) and had been weight stable for at least 2 years. The RMR was significantly lower (p<0.05) in the LOW group compared to the values of the ADQ group (1.19 vs. 1.29 kcal·FFM-1·hr-l, respectively); this difference represents a lower resting expenditure of 158 kcal·day-1. No differences were found in TEM between the two groups. These results suggest that a lower RMR is one mechanism that contributes to weight maintenance in a group of low- versus adequate-energy intake male athletes.

Fifteen adult male volunteers were assigned to sedentary, moderately strength-trained, and moderately endurance-trained groups (5 per group) to determine the effect of exercise training on energy expenditure (EE). Subjects were matched for age, weight, and height. Group appointments were based on activity questionnaires and American College of Sports Medicine standards. Subjects consumed a mixed diet of 40% fat, 20% protein, and 40% carbohydrate at weight maintenance intake for 3 weeks while continuing their exercise training programs. There was no significant difference between groups for 24-hr EE measured in the controlled environment of a room-sized calorimeter. Free-living EE measured with H2218O in endurance- and strength-trained groups was significantly higher (19.4% and 35.1%, respectively) than in the sedentary group. Moderate endurance and strength training increased free-living EE but did not affect 24-hr EE when groups followed standardized activity schedules. These results suggest that increased EE caused by moderate exercise training is limited to the energy required to complete the exercise.
