For years we have been told that all calories are equal. In theory, it doesn’t much matter what we eat, provided we don’t eat too much of it. But new research has called that approach into question. Harvard researchers have found that eating certain foods is associated with weight gain, while choosing other items can be associated with modest weight loss over the years.
Scientists even have a theoretical explanation: most of the foods that seem to promote weight gain cause a quick rise in blood sugar and insulin. Such high glycemic index foods send metabolic signals to our bodies that lead to fat storage.
If you’d like to learn more about following a diet that is low in glycemic index foods, you may want to check out our book, Recipes & Remedies from The People’s Pharmacy.
