1. What Was The Study

The objective of this study was to examine cardiometabolic effects by comparing a healthy plant-based (vegan) diet with a healthy omnivorous diet among 22 pairs of genetically identical twins.

2. What Did The Study Show

A recent study found that twins following a vegan diet for eight weeks exhibited lower levels of “bad” low-density lipoprotein (LDL) cholesterol, improved blood sugar levels, and more significant weight loss compared to their siblings consuming a diet of meat and vegetables. In just eight weeks, these individuals experienced a 10% to 15% reduction in LDL cholesterol, a 25% decrease in insulin, and a 3% decline in body weight, solely through the consumption of real food without animal products.

3. Takeaways

In the short term, this dietary approach demonstrates positive changes in weight and cardiovascular health. The vegan diet, characterized by increased vegetable intake, reduced saturated fat, and higher fiber content, contributes to improvements in cholesterol levels and the stabilization of blood sugar. While predominantly plant-based diets offer various benefits, it’s worth noting that the longest-lived individuals often include some meat in their diet, suggesting a potential balance between the two approaches for longevity.
