And Now for some news ….
Timing of Food Intake and Weight Loss Effectiveness
A recent study published in the International Journal of Obesity found that there is emerging literature demonstrating a relationship between the timing of feeding and weight regulation in animals.
However, whether the timing of food intake influences the success of a weight-loss diet in humans is unknown.
The present study was conducted to evaluate the role of food timing in weight-loss effectiveness in a sample of 420 individuals who followed a 20-week weight-loss treatment.
Late lunch eaters lost less weight and displayed a slower weight-loss rate during the 20 weeks of treatment than early eaters (P=0.002). Surprisingly, energy intake, dietary composition, estimated energy expenditure, appetite hormones and sleep duration was similar between both groups.
Nevertheless, late eaters were more evening types, had less energetic breakfasts and skipped breakfast more frequently that early eaters.
The Study concluded that eating late may influence the success of weight-loss therapy. Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distribution—as is classically done—but also the timing of food.

Amount of Weekly Exercise and Effectiveness
A recent study published in the journal Medicine and Science in Sports and Exercise examined the effects of three different frequencies of combined resistance and aerobic training on total energy expenditure (TEE) and activity related energy expenditure (AEE) in a group of older adults.
Seventy-two women, 60 – 74 years old, were randomly assigned to one of three groups:
- 1 day/week of aerobic and 1 day/week of resistance (1+1);
- 2 days/week of aerobic and 2 days/week resistance (2+2); or
- 3 days/week aerobic and 3 days/week resistance (3+3).
Body composition (DXA), feeling of fatigue, depression, and vigor (questionnaire), strength (1RM), serum cytokines (ELISA), maximal oxygen uptake (progressive treadmill test), resting energy expenditure, and TEE were measured before and after 16 weeks of training.
Aerobic training consisted of 40 minutes of aerobic exercise at 80% maximum heart rate and resistance training consisted of 2 sets of 10 repetitions for 10 different exercises at 80% of one repetition maximum.
All groups increased fat free mass, strength and aerobic fitness and decreased fat mass. No changes were observed in cytokines or perceptions of fatigue/depression. No time by group interaction was found for any fitness/body composition variable.
Nonexercise training activity related energy expenditure (NEAT) increased significantly in the 2+2 group (+200 kcal/day), group 1×1 showed a trend for an increase (+68 kcal/day) and group 3+3 decreased significantly (-150 kcal/day).
The study concluded that the results indicate that 3+3 training may inhibit NEAT by being too time consuming and does not induce superior training adaptations to 1+1 and 2+2 training.

Glycemic Load and Type 2 Diabetes
Although much is known about the association between dietary glycemic load (GL) and type 2 diabetes (T2D), prospective cohort studies have not consistently shown a positive dose-response relation.
The authors of a recent study published in The American Journal of Clinical Nutrition performed a comprehensive examination of evidence on the dose response that links GL to T2D and sources of heterogeneity among all prospective cohort studies on healthy adults available in the literature.
The study concluded that after the authors accounted for several sources of heterogeneity, findings from prospective cohort studies that related the GL to T2D appear robust and consistently indicate strong and significantly lower T2D risk in persons who consume lower-GL diets.
