“…Each volunteer was given written advice and targets to meet for the next appointment. For both dietary interventions, if the volunteer's body mass index was above 25 kg/m 2 , they were encouraged to lose weight using the methodology we have described before (Frost et al, 1991). Baseline anthropometric measurements, blood biochemistry, and three fasting glucose and insulin samples taken over half an hour were also collected.…”

Objective: Recent epidemiological and prospective trial evidence suggests that consumption of a low glycaemic index (LGI) diet will reduce coronary risk. We hypothesise that introduction of an LGI diet will improve the metabolic profile of patients who have undergone coronary artery bypass grafting. Design: We conducted a randomised parallel group trial comparing a control group (n ¼ 29, age 61.879 y), who received currently advocated healthy eating dietary advice only, to an intervention group, who received healthy eating advice emphasising LGI carbohydrates (n ¼ 26, age 63.679.4 y) over a 12-week period in free-living patients with coronary heart disease. Outcome measures included fasting glucose, insulin, total cholesterol, high-density lipoprotein cholesterol, very lowdensity lipoprotein cholesterol, low density lipoprotein cholesterol and triglycerides. Results: A significant lower dietary glycaemic index was achieved in the group assigned to an LGI diet compared to the healthy eating control group (7171 vs 8171); fibre intake was also higher in the LGI group (2071 vs 1571 g). All biochemical markers of glucose and lipid metabolism measured were similar after 12 weeks of the LGI diet or control diet. Discussion: The LGI group achieved a significant LGI and a higher dietary fibre intake. However, there was no measurable significant effect of either the LGI diet or the health eating diet on lipid levels; this may have been hidden by concurrent drug therapy.

“…The extensive literature on weight management includes only one small non-randomized audit that compared the 2512 kJ (600 kcal) approach with another fixed 5023 kJ (1200 kcal) diet. 11 Although the importance of a 12 week maintenance period is also emphasized in the SIGN publication, 2 little scientific evidence exists to show how this is best achieved and thus health service providers have not yet addressed it.…”

Weight management: a comparison of existing dietary approaches in a work-site setting

OBJECTIVES:(1) To compare the effectiveness a 2512 kJ (600 kcal) daily energy deficit diet (ED) with a 6279 kJ (1500 kcal) generalized low-calorie diet (GLC) over a 24 week period (12 weeks weight loss plus 12 weeks weight maintenance). (2) To determine if the inclusion of lean red meat at least five times per week as part of a slimming diet is compatible with weight loss in comparison with a diet that excludes lean red meat. DESIGN: Randomized controlled trial. SETTING: Large petrochemical work-site. PARTICIPANTS: One-hundred and twenty-two men aged between 18 and 55 y. MAIN OUTCOME MEASURES: Weight loss and maintenance of weight loss. INTERVENTION: Eligible volunteers were randomized to one of the four diet=meat combinations (ED meat, ED no meat, GLC meat, GLC no meat). One-third of subjects in each diet=meat combination were randomized to an initial control period prior to receiving dietary advice. All subjects attended for review every 2 weeks during the weight loss period. For the 12 week structured weight maintenance phase, individualized energy prescriptions were re-calculated for the ED group as 1.4 (activity factor)Â basal metabolic rate. Healthy eating advice was reviewed with subjects in the GLC group. All subjects were contacted by electronic mail at 2 week intervals and anthropometric and dietary information requested. RESULTS: No difference was evident between diet groups in mean weight loss at 12 weeks (4.3 (s.d. 3.4) kg ED group vs 5.0 (s.d. 3.5) kg GLC group, P ¼ 0.34). Mean weight loss was closer to the intended weight loss in the 2512 kJ (600 kcal) ED group. The dropout rate was also lower than the GLC group. The inclusion of lean red meat in the diet on at least five occasions per week did not impair weight loss. Mean weight gain following 12 weeks weight maintenance was þ 1.1 (s.d. 1.8) kg, P < 0.0001. No differences were found between groups. CONCLUSIONS: This study has shown that the individualized 2512 kJ (600 kcal) ED approach was no more effective in terms of weight loss than the 6279 kJ (1500 kcal) GLC approach. However the ED approach might be considered preferable as compliance was better with this less demanding prescription. In terms of weight loss the elimination of red meat from the diet is unnecessary. The weight maintenance intervention was designed as a low-input approach, however weight regain was significant and weight maintenance strategies require further development.

“…Weight losses with traditional dietary treatment are typically 3% or less 4,5 and drop-out rates can be as high as 58%. 6 Cognitive ± behavioural treatment (CBT) for obesity also focuses on weight loss, but incorporates psychological strategies to promote lifestyle change.…”

OBJECTIVE: To evaluate a modi®ed cognitive ± behavioural treatment (M-CBT) for weight management which addresses both the psychosocial costs and the physiological health risks of obesity, without a focus on weight loss. DESIGN: Randomized controlled trial comparing M-CBT with standard cognitive ± behavioural therapy (S-CBT). SUBJECTS: Sixty-three overweight women with body mass index (BMI) ! 28 kgam 2 , mean age 47.5 and mean BMI 35.4. MEASURES: Weight, waist and hip circumference, blood lipids, blood glucose, blood pressure, psychological wellbeing, depression, self esteem, stress, binge eating, eating style, body image, nutrient intake, aerobic ®tness, activity levels, patient satisfaction with treatment. RESULTS: Both M-CBT and S-CBT achieved improvements in a broad range of physical, psychological and behavioural variables. Weight loss in the S-CBT group was greater than in the M-CBT group immediately after treatment, but both groups lost weight. Participants in the M-CBT group continued to lose weight up to the 1 y follow-up. M-CBT was evaluated positively by participants. CONCLUSIONS: Both M-CBT and S-CBT programmes were successful at inducing modest weight loss, as well as improving emotional well-being, reducing distress, increasing activity and ®tness, improving dietary quality and reducing cardio-vascular disease risk factors. The improvements were maintained or continued at 1 y follow-up. These results suggest that treatment based on the new weight-control paradigm which emphasizes sustained lifestyle change without emphasis on dieting, can produce modest bene®ts to health and well-being.
