100 randomly assigned people are assigned to group 1 and put on the low-fat diet. Another 100 randomly assigned obese people are assigned to group 2 and put on a diet of approximately the same amount of food, but not as low in fat. So group 2 is the control, just the no diet. Group 1 is the low-fat group, so see if it actually works. After 4 months, the mean weight loss was 9.31 pounds for group 1. Let me write this down. The mean weight loss for group 1, let me make it very clear.
