An 8-week clinical trial with twins compared vegan diets with omnivorous diets. 02:15 LDL cholesterol levels improved in the vegans. 03:10 LDL is not a significant risk factor for cardiovascular disease. 04:40 Triglyceride and HDL levels shifted in the wrong direction in the vegans. 04:50 Waist circumference was tracked, but not reported in study results. 07:28 Prepared meals were given for the first 4 weeks, then they had to prepare their own. 09:20 HDL decreased in the vegan dieters. 09:45 Triglycerides increased with the vegan dieters, not omnivores. 12:45 Study protein, carb, and fat levels were similar between the diets, but calories differed. 14:25 Meat intake was mostly chicken. 15:05 Meat alternatives are ultra processed.  15:30 Only 1 participant chose to remain on the vegan diet after the study.
