A low-carbohydrate diet is more effective in reducing body weight than healthy eating in both diabetic and non-diabetic subjects.
"A low-carbohydrate diet is more effective in reducing body weight than healthy eating in both diabetic and non-diabetic subjects. P Dyson, S Beatty and DR Matthews. Diabetic Medicine 2007;24(12):1430-1435."
To determine the effect of a low-carb diet (40 g/day) on body weight, glycemic control, ketone production and lipid levels in subjects with and without T2D.
"Targets E: none Carb: ≤40g/day Protein: none Fat: limit saturated fat and use MUFA (eat lean meats) Advised to consume each day at least 200 ml of milk, 4–5 portions of fruit/vegs (mainly low-carb vegetables such as salads and green leafy vegetables). Intake E: 1313kcal/d Carb: 56.8g/d; 17.3%E Protein: 97.2g/d; 31.1%E Fat: 69.3g/d; 46.2%E"
Weight loss and BMI reductions were greater with the LC diet, but outcomes for lipids and HbA1c were similar between diet groups.
Ketones: BG NSS at end of study
"""In conclusion, there is evidence to support the hypothesis that LC diets may confer greater benefit in terms of weight loss compared with healthy-eating advice, and are not dangerous in the short term for people with and without T2D. Little is known about the long-term effects of these diets, and this present study is subject to post-study monitoring for 2 years with intention to report annual data."" "
