Food labels seem to provide all the information a thoughtful consumer needs, so counting calories should be simple. But things get tricky because food labels tell only half the story. A calorie is a measure of usable energy. Food labels say how many calories a food contains. But they do not say how many calories you actually get out of your food, which depends on how highly processed it is.

The Salk Institute in La Jolla, California, has published details of its research into a new diet pill called Fexaramine that, unlike anything before it, may well open the door to successful and safe global weight loss.

A simple potato extract may limit weight gain from a diet that is high in fat and refined carbohydrates, according to scientists at Montreal's McGill University. The results of their recent study were so surprising that the investigators repeated the experiment just to be sure.
People who go through chemotherapy say one of the most frustrating side effects is that even their favourite foods taste awful. Pasta tastes like cardboard, meat tastes metallic. Patients have no desire to eat and end up getting fewer calories and less nutrition when they need it most—to battle the cancer as well as the ravages of the therapy. Why?
The growing interest in eating healthy can at times have unhealthy consequences. Some doctors and registered dietitians say they are increasingly seeing people whose desire to eat pure or "clean" food—from raw vegans to those who cut out multiple major food sources such as gluten, dairy and sugar—becomes an all-consuming obsession and leads to ill health. In extreme cases, people will end up becoming malnourished.
Brazil, like most developing nations, is facing the blight of obesity thanks to changing eating habits and a rush to convenience foods. The country has published new dietary guidelines aimed at countering these trends, but they are based on foods, food patterns, and meals, not nutrients - an approach that is being hailed as 'revolutionary' by some industry commentators/critics including author Michael Pollan, food-industry watchdog Prof Marion Nestle and Canadian bariatric expert Yoni Freedhoff.
