“…Although early assessment of individual factors associated with weight loss could facilitate individualized intervention, only a few studies have examined the impact of tailored treatment on later outcomes. One study found that individuals allowed to choose their weight-loss diet at the start of treatment did not differ in weight loss at 1 year compared with those given no choice (33). However, little is known about the benefit of allowing individuals to change programmes after an initial lack of response.…”

SummaryObjectiveIdentifying early predictors of weight loss is key for developing personalized treatment. However, few individual factors have been identified that predict weight loss during intervention, other than early weight loss itself.MethodsWomen with overweight or obesity (n = 186, mean ± SD age 50.0 ± 10.6 years, body mass index 34.0 ± 4.2 kg m−2) participated in the Portion‐Control Strategies Trial, a 1‐year randomized controlled weight‐loss trial with three intervention groups. Early changes in eating behaviours and psychological factors were evaluated by questionnaires at baseline and Month 1. The influence of these early changes on the trajectory of weight loss from baseline to Months 3 and 12 was assessed by random coefficients models.ResultsAlthough there were no differences in weight loss between intervention groups at the end of the trial, certain individual factors were shown to predict both early weight loss at Month 3 and longer‐term weight loss at Month 12. Across all participants, increases in dietary restraint and healthy lifestyle ratings in the first month predicted more rapid weight loss from baseline to Month 3 (P < 0.05) and also predicted more rapid weight loss and slower regain from baseline to Month 12 (both P < 0.01). Early attendance and changes in disinhibition were not associated with subsequent weight loss.ConclusionsChanges in psychological and behavioural measures, such as restraint, in the first month of weight loss intervention predicted longer‐term weight loss in women. Early additional support or tailored treatment could promote long‐term success by reinforcing these behaviours.

“…Investigating whether outcomes differ between men and women is import in developing gender‐specific treatment programmes, if required 6, 7, 8, 9, 10, 11, 12. Differences in outcome after weight loss have been reported previously, with men commonly losing more body weight and fat than women 13.…”

“…5,6 Investigating whether outcomes differ between men and women is import in developing gender-specific treatment programmes, if required. [6][7][8][9][10][11][12] Differences in outcome after weight loss have been reported previously, with men commonly losing more body weight and fat than women. 13 This difference is mainly explained by the concept of the LED, in which a fixed daily energy intake is provided to both genders, despite men and women having significantly different energy requirements because men characteristically have a greater body mass.…”

AimsThe PREVIEW lifestyle intervention study (http://clinicaltrials.gov Identifier: NCT01777893) is, to date, the largest, multinational study concerning prevention of type‐2 diabetes. We hypothesized that the initial, fixed low‐energy diet (LED) would induce different metabolic outcomes in men vs women.Materials and methodsAll participants followed a LED (3.4 MJ/810 kcal/daily) for 8 weeks (Cambridge Weight Plan). Participants were recruited from 8 sites in Europe, Australia and New Zealand. Those eligible for inclusion were overweight (BMI ≥ 25 kg/m2) individuals with pre‐diabetes according to ADA‐criteria. Outcomes of interest included changes in insulin resistance, fat mass (FM), fat‐free mass (FFM) and metabolic syndrome Z‐score.ResultsIn total, 2224 individuals (1504 women, 720 men) attended the baseline visit and 2020 (90.8%) completed the follow‐up visit. Following the LED, weight loss was 16% greater in men than in women (11.8% vs 10.3%, respectively) but improvements in insulin resistance were similar. HOMA‐IR decreased by 1.50 ± 0.15 in men and by 1.35 ± 0.15 in women (ns). After adjusting for differences in weight loss, men had larger reductions in metabolic syndrome Z‐score, C‐peptide, FM and heart rate, while women had larger reductions in HDL cholesterol, FFM, hip circumference and pulse pressure. Following the LED, 35% of participants of both genders had reverted to normo‐glycaemia.ConclusionsAn 8‐week LED induced different effects in women than in men. These findings are clinically important and suggest gender‐specific changes after weight loss. It is important to investigate whether the greater decreases in FFM, hip circumference and HDL cholesterol in women after rapid weight loss compromise weight loss maintenance and future cardiovascular health.

Objective: To identify the dietary patterns of individuals with metabolic syndrome and determine associations with sociodemographic, lifestyle, anthropometric and biochemical features. Methods: We analyzed data of individuals with metabolic syndrome attending the nutrition outpatient clinic at a public university in São Paulo, from 2008 to 2011. We assessed food intake by 24-hour dietary recall and identified the dietary patterns using principal components analysis. Multivariate multiple linear regression models were applied to investigate possible associations between dietary patterns and the independent variables. We applied Pearson's correlations to evaluate possible associations between dietary patterns and biochemical and anthropometric variables. Results: Of the 166 outpatients enrolled, 65.7% (109) were women; 63.0% (103) were adults (21-59 years) and 37.0% were elderly (60-79 years). Most people were married, sedentary and obese, with incomplete primary education, non-smoking and non-alcoholic. We identified nine dietary patterns. There was a positive association between the "traditional Brazilian" dietary pattern (rice, beans and red meat) with men and a negative association with age, and the "prudent" (whole grains, soups) with women. There was a positive correlation between the "traditional Brazilian", "compensatory" (snacks, sweeteners, light products) and "mixed" (refined grains, fruits, oils) patterns with fasting glucose, and negative correlation between the "healthy" (vegetables and oilseeds) and waist circumference. Conclusion: The results of this study indicate that these individuals with metabolic syndrome have dietary patterns characterized by the presence of refined foods, fats, red meat and alcohol, associated with biochemical disturbance, as impaired fasting glucose and hypertriglyceridemia.
