  Purpose

This study will examine whether a higher protein meal replacement diet (consisting of 1 gram of protein per pound lean body mass) is more effective in causing weight loss compared to a standard meal replacement protein diet (consisting of ½ gram of protein per pound of lean body mass). The study will assign approximately 100 subjects (50 each) to the following arms 1) higher meal replacement diet program 2) standard meal replacement diet program. All participants will meet with a registered dietitian to provide nutrition education and behavior modification, including general exercise recommendations. As part of your participation, you must be willing to undergo a measurement of body fat, and blood tests, and be willing to use Herbalife Meal replacements as part of your diet for the duration of the study (one year).

Detailed Description:

There is concern that excess protein intake may be damaging to liver, renal function, and bone health. This study was designed to compare the effects of a high protein (HP) and an isocaloric meal standard protein (SP) weight loss plan on liver function, renal function and bone metabolism.
