Objective: To investigate weight loss expectations and goals among obese treatment seekers and to examine the relationships of these expectations and goals to treatment outcomes. Method: Participants were 180 obese men and women (age 43.8710.1 years; body mass index 37.674.2 kg/m 2 ) who received one of four-year-long treatments that combined behavioral and pharmacological methods. Before treatment, they reported the amount of weight they realistically expected to lose after 4, 12, 26 and 52 weeks of treatment, as well as their ultimate weight loss goals. Expectations and goals were compared across treatment groups and examined in relation to previous weight loss efforts, weight loss and regain in treatment, attrition, satisfaction with treatment and mood. Results: Participants in all treatment groups expected reductions at week 52 that were significantly greater than the 5-15% of initial weight they were told was realistic and significantly more than they had ever lost before. Weight loss expectations were unrelated to achieved weight loss in all groups but one, in which greater expectations were associated with greater losses. Failure to meet weight loss expectations for the first 26 weeks of treatment was related to lower satisfaction ratings, but was not related to weight regain or attrition over the next 26 weeks. Symptoms of depression were reduced from baseline, regardless of whether participants achieved or failed to achieve their expected weight losses. Conclusion: Across groups, we observed no negative consequences of having (and failing to meet) unrealistic expectations for weight loss.
Background Little is known about diet quality with a reduced-energy, low-fat, partial meal replacement (PMR) plan, especially in individuals with type 2 diabetes. The Action for Health in Diabetes (Look AHEAD) trial implemented a PMR plan in the intensive lifestyle intervention (ILI). Objective Compare dietary intake and percent meeting fat-related and food group dietary recommendations in ILI and diabetes support and education (DSE) groups at 12 months. Design Randomized controlled trial, comparing ILI to DSE, at 0- and 12-months. Participants/setting From 16 United States sites, the first 50% of participants (aged 45 to 76 years, overweight or obese, with type 2 diabetes) were invited to complete dietary assessments. Complete 0- and 12-month dietary assessments (collected between 2001 and 2004) were available on 2,397 participants (46.6% of total participants), with 1,186 randomized to DSE and 1,211 randomized to ILI. Main outcome measures A food frequency questionnaire assessed intake: energy; percent energy from protein, fat, carbohydrate, polyunsaturated fatty acids (PUFA), and saturated fats; trans fatty acids; cholesterol; fiber; weekly meal replacements (MRs); and daily servings from food groups from the Food Guide Pyramid. Statistical analyses performed Mixed-factor analyses of covariance (ANCOVA), using Proc MIXED with a repeated statement, with age, sex, race/ethnicity, education, and income controlled. Unadjusted chi-square tests compared percent meeting fat-related and food group recommendations at 12 months. Results At 12 months, ILI had a significantly lower fat and cholesterol intake and greater fiber intake than DSE. ILI consumed more servings/day of fruits; vegetables; and milk, yogurt & cheese; and fewer servings/day of fats, oils & sweets than DSE. A greater percentage of ILI than DSE participants met fat-related and most food group recommendations. Within ILI, a greater percentage of participants consuming ≥ 2 MRs/day than < 1 MR/day met most fat-related and food group recommendations. Conclusions The PMR plan consumed by ILI was related to superior diet quality.
The purpose of this study was to evaluate the influence of British army recruit training on the physical fitness and strength of female recruits. A total of 73 females (aged 17-23 years) of a single intake of Women's Royal Army Corps (WRAC) recruits were tested at the beginning and end of their 6-week recruit training programme at the WRAC training centre, Guildford. The battery of tests comprised the maximal cycle time for a standard NATO test as an indirect method of determination of maximal oxygen intake (VO2 max) using a cycle ergometer; maximal isometric hand grip strength (Max Grip); maximal isometric 38 cm upright pull strength (Max 38) and maximal incremental dynamic lift to 152 cm (IDL 152). In addition, body-weight and the sum of biceps, triceps, suprailiac and subscapular skinfold thicknesses were measured in order to assess alterations in fat-free mass and percentage of body fat (BF). The recruits responded to training with significant increases in mean VO2 max from 45.7 ml kg-1 min-1 (SD = 5.2) to 46.7 ml kg-1 min-1 (SD = 4.4) or 2.2% (p < .05), mean Max Grip from 263.1 N (SD = 52.2) to 304.9 N (SD = 54.0) or 15.9% (p < 0.001) and mean IDL 152 from 328.0 N (SD = 78.1) to 361.2 N (SD = 74.6) or 10.1% (p < 0.001). There was a significant increase in the mean body-weight of 0.61 kg or 1% (p < 0.05), mean fat-free mass of 1.05 kg or 2.4% (p < 0.001), and a significant reduction in the mean % BF by 3.3% (p < 0.001). It is concluded that female recruit training in the British army is effective in terms of increasing aerobic fitness, physical strength and fat-free mass and in reducing the percentage of body fat.
