Swedish Expert Committee: A Low-Carb Diet Most Effective for Weight Loss. Flashback to 2013, but it is interesting that it is in an “official” source that now overturns the last few decades of “official” guidelines.
The health care system has for a long time given general advice to avoid fat and calories. A low-carbohydrate diet has often been dismissed as a fad diet lacking scientific foundation. The time has now come to update knowledge in this area.
According to [Swedish Council on Health Technology Assessment], the only clear difference among different dietary recommendations is seen during the first six months. Here a low-carbohydrate diet, such as LCHF, is clearly more effective than today’s conventional advice.
From fad diet to best in test.
Exercise plays only a marginal role in weight loss:
[The report] also kills the idea that exercise plays an important roll in weight loss. Exercise may be very good for health, but: “Systematic reviews of the literature show that the addition of physical activity to a dietary intervention for individuals with obesity have, if any, a marginal effect on weight loss at the group level.”
