The Effect of a High Protein, High Fiber Dietary Supplement on Weight and Fat Loss
Study Details
Study Description
Brief Summary
The objective of this study is to investigate the effect of a high protein, high fiber dietary supplement on weight and fat loss in healthy overweight adults. Half of participants will receive a high protein, high fiber supplement twice a day for 12 weeks, and half of the subjects will receive a placebo (that contains the same amount of calories as the supplement) twice a day for 12 weeks.
