Low carbohydrate diets are attracting a lot of interest and have become a bone of contention in the management of diabetes. This critical review assessed nine meta-analyses containing 153 studies but found only 12 studies that met their inclusion criteria: studies longer than 4 weeks in adults with type 2 diabetes; carbohydrate intake less than 45%E; and dietary intake assessed at the end of the study. They found no difference in metabolic markers between normal and low-carb diets, although weight loss with a low-carb diet was greater in one study. Dietary assessment at the end of the study period showed carbohydrate intakes in very low-carb diet subjects (target <50g/day) were up to three times larger than prescribed suggesting difficulty in sustaining strict carbohydrate limits.
