Vegan diets do not significantly affect blood pressure, HDL-C, or triglycerides compared to control diets in individuals with overweight or type 2 diabetes.
Do not expect a vegan diet to automatically lower your blood pressure or triglycerides if they are currently normal or if the diet is not carefully managed. The primary benefits observed were weight loss, improved HbA1c, and reduced LDL cholesterol. Monitor your BP and triglycerides separately.
GoodRefutesMEDIUM confidence
We identified no effect on blood pressure, high-density lipoprotein cholesterol, and triglycerides.
Why this rating
Based on RCTs with moderate certainty for BP and low for lipids.

- Adhering to a vegan diet for at least 12 weeks significantly reduces body weight, BMI, HbA1c, total cholesterol, and LDL-C in individuals with overweight or type 2 diabetes compared to control diets.Good
- The magnitude of weight loss and HbA1c reduction is greater when vegan diets are compared to habitual (passive) control diets rather than other active dietary interventions.Good

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
