Get into a conversation about weight loss, and it’s pretty inevitable that calories will make a starring appearance. Whether you’re counting, restricting or just generally obsessing over them, they’ve become the be-all and end-all of so many diet plans.
But many scientists remain unconvinced of their importance. Another piece of research has been published in a respectable journal showing that many of the current assumptions about how calories impact on our weight are simply not true.
In his research paper Dietary Glycemic Index and Obesity, DS Ludwig explains:
The concept that “a calorie is a calorie†underlies most conventional weight loss strategies. According to this principle, obesity results from an imbalance between energy intake and expenditure. The proposed cure is to eat less and exercise more. However, calorie-restricted, low fat diets have poor long-term effectiveness in the outpatient setting. In a sense, these diets may constitute symptomatic treatment that does not address the physiologic drives to overeat. From a hormonal standpoint, all calories are not alike.
