Previous studies with animal models suggest a relationship between the timing of feeding and weight regulation. Frank Scheer, from Brigham and Women’s Hospital (Massachusetts, USA), and colleagues evaluate the role of food timing in weight-loss effectiveness in a group of 420 individuals who followed a 20-week weight-loss treatment. The participants were divided into two groups: early-eaters and late-eaters, according to the self-selected timing of the main meal, which in this Mediterranean population was lunch. During this meal, 40% of the total daily calories are consumed. Early-eaters ate lunch anytime before 3 p.m. and late-eaters, after 3 p.m. They found that late-eaters lost significantly less weight than early-eaters, and displayed a much slower rate of weight-loss. Late-eaters also had a lower estimated insulin sensitivity, a risk factor for diabetes. Researchers found that timing of the other (smaller) meals did not play a role in the success of weight loss. However, the late eaterswho lost less weightalso consumed fewer calories during breakfast and were more likely to skip breakfast altogether. Late-eaters also had a lower estimated insulin sensitivity, a risk factor for diabetes. Writing that: “Eating late may influence the success of weight-loss therapy,” the study authors submit that: “Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distributionas is classically donebut also the timing of food.”

Tip #124 - Work Out at Work
If you are one of the millions with a desk job, be sure to get out of your chair once an hour for 5-10 minutes to do some standing stretches.
Gently stretch your shoulders, arms, neck, back, sides, chest, and calves. This can improve circulation and relieve neck and back stiffness.
Done regularly, this also can improve your motivation to do some serious aerobic exercise after your workday ends.
