“…After the 20 duplicates were removed, 35 studies remained. Of the 35 papers given consideration for inclusion in this review, we excluded 31 for the following reasons: 18 were conducted in cohorts that were not < 18 years old (23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40); three were not intervention studies (41)(42)(43), three were review papers (44)(45)(46) and one was a doctoral dissertation (47); and six did not have any blood analysis relating to lipoproteins, insulin or glucose (48)(49)(50)(51)(52)(53). The papers associated with the doctoral dissertation were located ( n = 2) and excluded as they were not intervention studies (54,55).…”

Effects of resistance training on metabolic fitness in children and adolescents: a systematic review

2007

SummaryThe majority of resistance training (RT) research with children to date has focused on pre-adolescents and the safety and efficacy of this type of training rather than the potential metabolic health benefits. Our objectives, using computerized databases, were (i) to systematically review studies utilizing RT interventions with children and adolescents < 18 years; (ii) to investigate the metabolic health outcomes (adiposity, lipids, insulin, glucose) associated with RT; (iii) to provide recommendations for future investigations. A total of 12 studies met the review criteria. There is only a small amount of evidence that children and adolescents may derive metabolic health-related adaptations from supervised RT. However, methodological limitations within the body of this literature make it difficult to determine the optimal RT prescription for metabolic fitness in children and adolescents, and the extent and duration of such benefits. More robustly designed single modality randomized controlled trials utilizing standardized reporting and precise outcome assessments are required to determine the extent of health outcomes attributable solely to RT and to enable the development of evidence-based obesity prevention and treatment strategies in this cohort.

“…The subjects who have a family history of obesity and obesity in childhood seemed to have more difficulty for weight reduction 19. The subjects who have a high RMR and high VO 2 max seemed to loose weight more easily 10. This study failed to demonstrate a significant association between the outcome of weight reduction and any risk factors.…”

Analysis of the Factors Affecting the Success of Weight Reduction Programs

Obesity is a risk factor for numerous health problems. Behavior therapy is important for obesity treatment. The aim of the present study was to identify the parameters that are associated with successful weight reduction. A database of 123 subjects who underwent weight reduction programs at the Center for Health Promotion, Samsung Medical Center from June 2001 through November 2004 was retrospectively analyzed. The goal of the program was to reduce the body weight by more than 5% during the follow-up period. The study population was divided into 2 categories (the success group and the failure group) based on the outcome of weight reduction. We analyzed the demographic, laboratory and clinical parameters to determine the predictors of successful weight reduction. The prevalence of success group was 36.6% (45/123). Significant correlations for successful weight reduction were found for the follow up period and the frequency of medical visits. Our results suggest that strong motivation was the most important factor for successful weight reduction.

“…In contrast, exercise alone led to greater body fat loss and a slight increase in lean mass despite the substantial negative energy balance. Of course, these model predictions could not be corroborated with experimental data in this group, but they are generally in line with the expected effects of diet restriction and exercise training (10–13).…”

Diet versus exercise in “the biggest loser” weight loss competition

The Biggest Loser television show is watched by millions of people worldwide. Obesity experts have criticized its portrayal of an unrealistic intervention that raises false expectations for weight loss. Here, I quantify the diet and exercise intervention using a validated computational model of metabolism to integrate data on energy expenditure, body weight and body fat collected during The Biggest Loser competition.Participant age, body mass index, weight, and percent body fat at baseline were 33 ± 11 y, 48.7 ± 10.1 kg/m2, 144.9 ± 39.4 kg, and 49 ± 6 % (mean ± SD), respectively. During the first phase of the competition when the contestants were isolated in a boot camp environment, the average rate of weight loss was 0.4 ± 0.1 kg/d which decreased to 0.19 ± 0.1 kg/d after returning home for the final phase. The total weight loss was 58.2 ± 26 kg with 81.6 ± 8.4 % coming from body fat. The computer simulations closely matched the data and calculated that average energy intake during the first phase was 1300 kcal/d while participating in 3.1 h/d of vigorous exercise. After returning home, energy intake increased to 1900 kcal/d and vigorous exercise decreased to 1.1 h/d. Simulation of diet alone resulted in 34 kg of weight loss with 65% coming from body fat, whereas exercise alone resulted in a loss of 27 kg with 102% from fat. Simulated weight loss maintenance could be achieved with a modest 20 min/d of vigorous exercise and a 3000 kcal/d diet.
