It seems that carbs have replaced fats as the enemy of a healthy diet. Many people believe the healthiness of foods are based on their glycemic index, although research on low-glycemic diets show little evidence (1, 2, 3, 4, 5, 6, 7) even for diabetics (8, 9, 10). This lack of evidence is also found for the carbohydrate-insulin model of obesity, which says that obesity is caused by the insulin response they carbohydrates create (11,12).
These findings are also found with long-term keto diets that test real-world effectiveness. Meta-analyses reveal that they do not provide clinically relevant weight loss differences when compared to higher-carb diets (13,14).
We are not saying that cutting carbs intake cannot be helpful, especially processed carbs, we think it can be especially if it leads to healthier eating choices. But if cutting carbs makes you feel bad and eventually eat worse because you can not stick to it then you should find a diet that works for you.
