Study on Replacing Animal Protein with Vegetable Protein

Eleven obese volunteers took part in a 12-week study during 8 weeks of which 2 meals of their control 1000 kcal diets were replaced by a soya based liquid formula (1 month) or a milk based liquid formula (1 month).

Why was this study done?

The health benefits of a plant-based diet are many. This study was designed to investigate the effects of replacing animal protein (milk) with vegetable-based protein (soy) during a weight loss program to see the effects of both diets on blood lipids (cholesterol, LDL, HDL).

What did the study find?

During the twelve-week study, an average of 2.5 kg (5.5 lbs.) were lost on a 1000 kcal diet where two meals were replaced with either a milk or a soy drink. Those participants who were on the soy diet had a significant reduction in total cholesterol and LDL cholesterol levels.
