Although many trendy diets try to limit carbs, not all carbohydrates are the same. Most of the weight gain anxiety dieters get revolves around the belief that eating “fast carbs” will make you fat. However, a new study finds there’s really no difference between fast or slow carbs when it comes to weight gain — or weight loss.
In a report commissioned by the Grain Foods Foundation, scientists discovered little difference in how high-glycemic and low-glycemic foods impact weight management. The glycemic index (GI) ranks how quickly a certain food raises blood sugar levels. The theory is that high-GI foods raise glucose levels and insulin secretion, which may lead to health issues through overeating.
Moreover, scientists believe high-GI foods promote fat storage and increase a person’s obesity risk. However, a review of nearly two million adults across 34 previous studies finds the impact of fast carbs is no more harmful than slow carbs.
“This study is the first to definitively demonstrate that fast carbs do not make you fat,” says study co-author Glenn Gaesser, PhD, a professor of exercise science in the College of Health Solutions at Arizona State University, in a media release. “Contrary to popular belief, those who consume a diet of high-GI foods are no more likely to be obese or gain weight than those who consume a diet of low-GI foods. Furthermore, they are no less likely to lose weight.”
The study authors add that “GI, as a measure of carbohydrate quality, appears to be relatively unimportant as a determinant of BMI or diet-induced weight loss.”
