The Impact of Health at Every Size® Versus a Weight Loss Intervention on Diet

Approximately 25% of weight lost during restrictive diets (without exercise) is lean body mass (LBM). No study has yet investigated the impact of the rate of weight loss (RWL) on LBM and fat mass (FM). The purpose of this study was to investigate the relationships between the RWL and body composition in older obese women. Twenty obese postmenopausal women aged between 51 and 74 years enrolled in a 5 week dietary weight loss intervention. Subjects were characterized according to their RWL (low RWL < 0.74 kg·week–1 (n = 9) vs. high RWL ≥ 0.74 kg·week–1 (n = 11)). Total and trunk FM and LBM (by dual-energy X-ray absorptiometry) were measured before and after weight loss. A significant correlation was observed between the RWL (kg·week–1) and changes in LBM (kg·week–1) (r = 0.75; p = 0.0002). However, no association was observed with changes in FM (kg·week–1) (r = 0.40; p = 0.08). Both groups showed a similar decrease in FM (low RWL, –2.7 ± 0.9 kg,; high RWL, –3.2 ± 0.8 kg; p = 0.38), whereas losses in LBM were significantly higher in the high RWL than in the low RWL group (–1.6 ± 1.2 kg vs. –0.4 ± 1.1 kg; p = 0.05). An RWL > 0.74 kg·week–1 was associated with a greater loss of LBM, but had no extra benefits on FM after a 5 week weight loss program. Current guidelines, which recommend RWL up to 0.91 kg·week–1, might not be optimal to prevent decreases in LBM in postmenopausal women when no exercise is added.

The Impact

167 Background: Evidence increasingly links obesity to increased risk of cancer recurrence and mortality in breast and other cancers, but few studies have evaluated weight loss interventions in cancer patients. We evaluated the impact of a group-based weight loss intervention implemented through an oncology clinic on weight and other outcomes in a mixed population of cancer survivors. Methods: Overweight and obese cancer survivors were randomized 1:1 to immediate or delayed participation in a 15-week group-based weight loss program focused on calorie restriction and increased physical activity. Weight, body composition, physical activity, fitness and quality of life were assessed at baseline and 15 weeks. Changes in measurements between baseline and 15 weeks were compared using Wilcoxon rank sum tests. The primary outcome was change in weight between baseline and 15 weeks between groups. Results: 60 participants were randomized; 30 to intervention and 30 to control. Median age was 52, average BMI was 31.8 kg/m2, 97% of participants were women, and 80% had breast cancer. Intervention participants lost 5.3% of baseline weight at 15 weeks vs 0.2% weight gain in controls (P < 0.001) (Table). Improvements in fitness (6-minute walk test) and physical functioning (EORTC QLQ C30) were also observed in the intervention group vs. controls. Conclusions: We found thatparticipation in a 15-week group-based intervention resulted in weight loss and improvements in fitness and physical functioning in overweight and obese cancer survivors. More work is needed to evaluate the feasibility and sustainability of weight loss programs implemented through oncology practices. Clinical trial information: NCT01978899. [Table: see text]

Satiety Responsiveness

Studies have shown that individuals with low satiety efficiency may be more susceptible to weight gain, but little is known about the effect of weight loss intervention outcomes in these individuals. This study aimed to evaluate the impact of an energy-restricted weight loss intervention on eating behavior traits and psychobehavioral factors in individuals differing in their satiety responsiveness. A pooled cohort of individuals who were overweight or obese (n = 100; aged 39 ± 9 years) participating in a 12- to 15-week weight loss program targeting an energy deficit of 500–700 kcal/day were included in this study. Satiety responsiveness was determined by a median split of the mean satiety quotient based on appetite sensations measured in response to a test meal at baseline (low satiety responsiveness (LSR) vs. high satiety responsiveness (HSR)). Anthropometric variables, eating behavior traits, psychobehavioral factors, and ad libitum energy intake were assessed before and after the intervention. Although similar weight loss was observed between the LSR and HSR groups (−3.5 ± 3.2 vs. –3.8 ± 2.8 kg, p = 0.64) in response to an energy-restricted weight loss intervention, changes in eating behavior traits were different between groups. Individuals with LSR had a higher increase in cognitive restraint (+5.5 ± 4.1 vs. +3.5 ± 3.5, p = 0.02) and some of its subscales and a lower decrease in situational susceptibility to disinhibition (−0.6 ± 1.1 vs. −1.2 ± 1.3, p = 0.02) in response to the intervention compared to the HSR group. In conclusion, energy-restricted weight loss intervention seems to trigger undesirable changes in some eating behavior traits in individuals more vulnerable to overeating, which could increase their susceptibility to weight regain.
