Adopting a predominantly plant-based dietary pattern improves cardiovascular health markers, including LDL cholesterol, fasting insulin, and body weight, compared to an omnivorous diet.
Start by swapping one animal protein source per day with a plant-based alternative (like lentils or tofu). Focus on adding vegetables, fruits, whole grains, and legumes rather than just cutting out meat. If you experience bloating, increase your fiber intake slowly over weeks rather than all at once. Consider consulting a dietitian to ensure you are getting enough B12 and iron, especially if you are vegan.
The vegan diet participants also showed an approximate 20% drop in fasting insulin and lost an average of 4.2 pounds of body weight more than the omnivore-diet participants, both statistically significant changes... At the end of the study (8-week), LDL-C had dropped to 95.5 mg/dL for vegan-diet participants and 116.1 mg/dL for omnivore-diet participants.
Why this rating
Supported by RCTs (identical twins, SWAP-MEAT) and large observational cohorts (EPIC, Adventist).

- 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
