As I wrote in op-eds for the Wall Street Journal61 and Medscape,62 the Lancet Public Health study is based on very thin data. The questionnaire underlying the report left out questions regarding popular foods, such as pizza and energy bars, and did not consider alcohol consumption. Moreover, the “low-carb” diet group in this study included people eating up to 37% of calories as carbohydrates—not low-carb according to the latest science. Ultimately, this is the kind of data that can show association but not establish causation, which means it is the kind of data one can use to generate hypotheses but not prove them. This kind of data would never be considered sufficient to approve a drug, for instance. The same standards should be applied to diet. Quite a few researchers, including myself, had our critiques published in Lancet Public Health.63 The authors replied but did not respond to most of the criticisms.
Throughout this article, we looked at the data and the principles behind how low-carb dieting affect patients with diabetes, but we never addressed what you can do about it directly. If you’d like to learn about practical strategies that may help you reverse insulin resistance and improve your blood sugar and HbA1C levels, I recommend reading these articles:
I’ve been type 2 for about 15 years was pretty stable with diet and Metformin for 10 years. But eventually started trying more aggressive treatment like Victoza and without fail in 4 years I was on slow acting insulin. I lost weight lowered carb intake to 40mg or less in the morning my breakfast has been no carbs. People need to realize every diabetic is different you must manage it how it keeps you with good A1C levels. I myself got off insulin for a year and half but my fasting levels slowly increased again. Reversing diabetes is not possible. Reducing the effects is possible and more likely the better you monitor yourself and do what you need to do. Depending on medications or diets or counting carbs will all help but not cure the diabetes. These all are things that reduce its ability to affect your health negatively.
In its 2016 report “Healthy Eating Guidelines & Weight Loss Advice,” the Public Health Collaboration, a U.K. nonprofit, evaluated evidence on low-carbohydrate, high-fat diets. (The Keto diet falls under the LCHF umbrella.) Among 53 randomized clinical trials comparing LCHF diets to calorie-counting, low-fat diets, a majority of studies showed greater weight loss for the Keto-type diets, along with more beneficial health outcomes. The collaboration recommends weight-loss guidelines that include a low-carbohydrate, high-fat diet of real (rather than processed) foods as an acceptable, effective and safe approach.
A ketogenic diet helps control blood sugar levels. It is excellent for managing type 2 diabetes, sometimes even leading to complete reversal of the disease. This has been proven in studies. It makes perfect sense since keto lowers blood-sugar levels, reduces the need of medications and reduces the potentially negative impact of high insulin levels.
