A new study published in the British Medical Journal found that overweight adults who followed a low carbohydrate, high fat diet burned 250 more calories a day than those on a high carbohydrate diet. This is the largest and longest study that challenges the belief that all calories are the same to the body.
As we lose weight, our body adapts by burning fewer calories. This makes long term, intentional weight loss challenging because our bodies are fighting this process in an attempt to maintain weight. The researchers in this study believe higher carbohydrate diets increase insulin levels which causes our bodies to store excess calories. With fewer calories available to the body, hunger increases and metabolism slows, which ultimately leads to weight gain.
