There is low to high ( majority moderate ) certainty for small improvements of unclear clinical importance in plasma glucose , triglycerides , and HDL concentrations favoring low-carbohydrate food at half of the prespecified time points .
There was little to no difference in LDL concentration or any of the secondary outcomes ( body weight , waist circumference , blood pressure , quality of life ) in response to either of the diets ( very-low- to high-certainty evidence ) .
Conclusions Currently available data provide low- to moderate-certainty evidence that dietary carbohydrate restriction to a maximum of 40 % yields slightly better metabolic control of uncertain clinical importance than reduction in fat to a maximum of 30 % in people with T2D .
Background It remains uncertain which diet is best for people with type 2 diabetes ( T2D ) .
Objective We compared the effects of dietary carbohydrate restriction with fat restriction on markers of metabolic syndrome and quality of life in people with T2D .
Slowing Down the Progression of Type 2 Diabetes: We Need Fair, Innovative, and Disruptive Action on Environmental and Policy Levels!
Over the past decades , we have observed an increase of prevalence of diabetes  in many countries along with significant differences in prevalence trends between countries worldwide ( 1 ) . In Europe and other Western countries , the prevalence rate reaches a plateau or has slowed down on the level of ∼8–10 % . In Asia , a continuous rise in prevalence has been monitored , similar to that in Africa , and an explosion of diabetes prevalence can be observed in the Arabic region . Surprisingly , in each of the countries , there is a significant number of people who do not develop  diabetes  during their lives despite living unhealthy lifestyles in similar environments — in Europe , an estimated 10 % of the population ( 2 ) . These people might be the secret answer to successful individual diabetes prevention , but we still do not underst and the detailed mechanisms of why some people develop diabetes— and why others do not . What we can do is observe individual lifestyle and environment as determinants for the development or prevention of diabetes and the respective risk factors including genetic susceptibility . The interplay between these determinants , influencing the probability of the individual staying healthy or how a person learns or chooses a healthy lifestyle , will define success in diabetes prevention ( 3 ) . Innovative actions are needed to slow down the progression of type 2 diabetes . The purpose of this article is to offer innovative policy and environmental strategic activities design ed to enable sustainable diabetes prevention with scalability on national level . # # # Why Do We Need Environmental and Policy Changes in Diabetes Prevention ? Diabetes prevention is a success story , but it generates new challenges . Throughout the past 15 years , a number of r and omized controlled trials have sought to test various interventions to prevent diabetes ( 4 ) . The results are overwhelmingly positive on an individual level , with a significant relative diabetes risk reduction attributed to lifestyle and pharmacological intervention ( 5
