While commercial dietary weight-loss programs typically advise exercise, few provide actual programing. The goal of this study was to compare the Curves Complete 90-day Challenge (CC, n = 29), which incorporates exercising and diet, to programs advocating exercise (Weight Watchers Points Plus (WW, n = 29), Jenny Craig At Home (JC, n = 27), and Nutrisystem Advance Select (NS, n = 28)) or control (n = 20) on metabolic syndrome (MetS) and weight loss. We randomized 133 sedentary, overweight women (age, 47 ± 11 years; body mass, 86 ± 14 kg; body mass index, 35 ± 6 kg/m 2 ) into respective treatment groups for 12 weeks. Data were analyzed using chi square and general linear models adjusted for age and respective baseline measures. Data are means ± SD or mean change ± 95% confidence intervals (CIs). We observed a significant trend for a reduction in energy intake for all treatment groups and significant weight loss for all groups except control: CC (−4.32 kg; 95% CI, −5.75, −2.88), WW (−4.31 kg; 95% CI, −5.82, −2.96), JC (−5.34 kg; 95% CI, −6.86, −3.90), NS (−5.03 kg; 95% CI, −6.49, −3.56), and control (0.16 kg, 95% CI, −1.56, 1.89). Reduced MetS prevalence was observed at follow-up for CC (35% vs. 14%, adjusted standardized residuals (adjres.) = 3.1), but not WW (31% vs. 28% adjres. = 0.5), JC (37% vs. 42%, adjres. = −0.7), NS (39% vs. 50% adjres. = −1.5), or control (45% vs. 55% adjres. = −1.7). While all groups improved relative fitness (mL·kg −1 ·min −1 ) because of weight loss, only the CC group improved absolute fitness (L/min). In conclusion, commercial programs offering concurrent diet and exercise programming appear to offer greater improvements in MetS prevalence and cardiovascular function after 12 weeks of intervention.Key words: diet, exercise, metabolic syndrome.Résumé : Les programmes commerciaux de perte de poids recommandent généralement la pratique de l'exercice physique, mais peu offre une programmation réelle. Comparer sur les plans du syndrome métabolique (« MetS ») et de la perte de poids le programme Curves Complete 90-day Challenge (« CC », n = 29) qui incorpore une diète et des exercices physiques aux programmes qui recommandent l'exercice physique : Weight Watchers Points Plus (« WW », n = 29), Jenny Craig At Home (« JC », n = 27) et Nutrisystem Advance Select (« NS », n = 28) ou contrôle (n = 20). On répartit aléatoirement 133 femmes sédentaires et en surpoids (âge, 47 ± 11 ans; masse corporelle, 86 ± 14 kg; indice de masse corporelle, 35 ± 6 kg/m 2 ) dans les groupes de traitement respectif pour une période de 12 semaines. On effectue l'analyse du chi-carré et on utilise les modèles linéaires généraux ajustés à l'âge et aux mesures initiales respectives. Les données présentées sont la moyenne ± l'écart-type et la variation moyenne ± intervalle de confiance (IC) 95 %. Les résultats révèlent une tendance significative vers une diminution de l'apport énergétique dans tous les groupes de traitement et une perte de poids significative dans tous les groupes à l'exception du groupe de co...

(1) Background: Limited information exists on the prevalence of low energy availability (LEA) in collegiate team sports. The purpose of this study was to examine the prevalence of LEA in collegiate women soccer players. (2) Methods: Collegiate women soccer athletes (n = 18, height: 1.67 ± 0.05 m; body mass: 65.3 ± 7.9 kg; body fat %: 24.9 ± 5.6%) had their body composition and sport nutrition knowledge assessed in the pre-season. Energy availability was assessed mid-season using a 4-day dietary log and activity energy expenditure values from a team-based monitoring system. A validated screening tool was used to screen for LEA. (3) Results: The screening tool classified 56.3% of athletes as at risk of LEA (<30 kcal/kg of FFM); however, the actual dietary intake identified 67% as LEA. Athletes identified as non-LEA consumed significantly more absolute (p = 0.040) and relative (p = 0.004) energy than LEA athletes. (4) Conclusions: There was a high prevalence of LEA among collegiate women soccer athletes. Although previously validated in women endurance athletes, the LEA screening tool was not effective in identifying those at risk of LEA in this sample of athletes.

Our findings suggest that a low-moderate calorie diet partitioned for CHO and PRO preference is equally effective when combined with a structured exercise program for reducing the prevalence of MetS prevalence in overweight/obese women.

To determine whether adherence to a repeating 30-d non-linear diet intervention while participating in a supervised exercise program that includes resistance-exercise would promote weight and fat loss without weight loss plateau and whether alterations in carbohydrate and protein intake may influence results.Methods: Fifty sedentary and obese pre-menopausal females (35.2±7.6 years; 88.7±18 kg, 32.6±6 kg/m 2 , 42.5±4.2% fat) were randomly assigned to an exercise-only (EX) or EX plus diets containing higher proportions of carbohydrate or protein. Diets were hypoenergetic for 30-d ( 7-d at 1,200 kcals/d, 21-d at 1,500 kcal/d), more isoenergetic for 30-d (2,200 kcals/d), and repeated three times during a 24-wk intervention. Diets were either 45:30:24 (HCD) or 30:45:25 (HPD) carbohydate:protein:fat. All participants performed 30-min resistance exercise (3 d/wk) and a brisk walking program (3 d/wk). Data were analyzed by general linear model (GLM) statistics with repeated measures and presented as mean changes from baseline (mean [UL, LL]).
