A very low-carbohydrate diet improves metabolic syndrome components (HDL, triglycerides, insulin sensitivity) more effectively than low-fat or low-glycemic index diets during weight-loss maintenance, despite potentially increasing stress hormones (cortisol) and inflammation (CRP).

For long-term health markers like cholesterol and blood sugar, a very low-carbohydrate diet may offer better improvements than low-fat or low-glycemic diets after weight loss. However, monitor your stress levels and inflammation, as this diet may increase cortisol and CRP in some individuals.

Regarding components of the metabolic syndrome... were most favorable with the very low-carbohydrate diet... However, CRP tended to be higher with the very low-carbohydrate diet... 24-hour urinary cortisol excretion... was highest with the very low-carbohydrate diet.

Why this rating

Same study as N1; high internal validity but short duration limits long-term inference.
