Kahdeksan RCT-tutkimuksen meta-analyysissä keto voittaa mennen tullen virallisesti suositellun runsasrashiilihydraattisen ruokavalion lihavuuden ja t2d:n hoidossa, mitta koska tämä tulee teollisuuden korruptoimasta Oxfordin yliopistosta, tutkijat ilmoittivat, ettei ketoa silti voi suositella. Tekosyy: ihmiset eivät muka pysy sillä.

Abstract
Context
There is renewed interest in using very low-carbohydrate ketogenic (VLCK) diets to manage diabetes. Many clinical trials have been published, often with mixed results.
Objective
This meta-analysis compares the effect of a VLCK diet on glycemic control, body weight, lipid profile, medication use, and dropouts with that of recommended diets for 12 weeks or longer in people with type 2 diabetes.
Data Sources
Ovid MEDLINE, Ovid Embase, CENTRAL, and CINAHL databases were searched (January 1980 through September 2019).
Study Selection
Two authors independently reviewed search results to select randomized controlled trials (RCTs) comparing a VLCK diet (carbohydrate intake < 50 g/d or < 10% of total energy) with any recommended diet for type 2 diabetes in adults. Discrepancies were resolved after consulting with the third author.
Data Extraction
Eight RCTs with 648 participants were identified.
Results
Compared with control diets, the VLCK diet resulted in a greater decrease in hemoglobin A1c after 3 months (weighted mean difference[WMD]: −6.7 mmol/mol; 95%CI, −9.0 to −4.4) (WMD: −0.61%; 95%CI, −0.82 to −0.40; P < 0.001; moderate-certainty evidence) and after 6 months (WMD: −6.3 mmol/mol; 95%CI, −9.3 to −3.5) (WMD: −0.58%; 95%CI, −0.85 to −0.32; low-certainty evidence). There was a significantly greater weight loss with the VLCK diet after 3 months (WMD: −2.91 kg; 95%CI, −4.88 to −0.95; low-certainty evidence) and after 6 months (WMD: −2.84 kg; 95%CI, −5.29 to −0.39; low-certainty evidence). The VLCK diet was not better than a control diet after 12 months. It was superior in decreasing triglyceride levels, increasing high-density lipoprotein cholesterol levels, and reducing the use of antidiabetic medications for up to 12 months.
Conclusion
The VLCK diet appears to control glycemia and decrease body weight for up to 6 months in people with obesity and diabetes. Beneficial changes in serum triglycerides and high-density lipoprotein cholesterol, along with reductions in antidiabetic medications, continued in the VLCK group until 12 months. However, the quality of currently available evidence is not sufficient to recommend VLCK diets. A major limitation of the VLCK diet is patients’ lack of adherence to carbohydrate restriction.
