A study found that consumption of sugar-sweetened drinks inside and outside high schools in Boston declined from 1.71 servings a day on average in 2004 to 1.38 servings in 2006, driven by a ban on the sale of such drinks in the city's public schools in 2004. The decline resulted in students consuming 45 fewer calories a day, which could slash as much as 40% of extra calories that contribute to the increasing average weight among children, the study noted.
Participants with an IRS1 gene variation who went on a high-carbohydrate diet lost more weight and had better insulin control than those with the gene variant who were on a low-carb diet, a trial found.
Researchers at Monell Chemical Senses Center say they have learned that a woman's diet during pregnancy affects her baby's preferences for food later.

The protein nesfatin-1 helped reduce food intake and increase fatty acid oxidization and use of stored fat in rats, a study found. The findings in the journal Endocrinology suggest that the protein may help obese patients and those with type 2 diabetes lose weight and keep their appetite and blood glucose levels under control, experts said.
So-called "healthy" drinks can serve up unhealthy doses of calories and sugar, and dairy products come with digestive problems, so drinking water really is best, says naturopathic physician Sandra Olic. She recommends "reverse osmosis" water with added trace minerals, and says fad drinks such as coconut water are OK for replenishing electrolytes after a workout.
