Participants Our goal was to recruit 800 overweight and obese subjects (400 at each site), of whom about 40% would be men. Surgical procedures are commonly categorized by urgency, type of procedure, body system involved, degree of invasiveness, and special instrumentation. Emergency surgery is surgery which must be done promptly to save life, limb, or functional capacity. gov number, NCT00072995.

By degree of invasiveness of surgical procedures: Minimally-invasive surgery involves smaller outer incision(s) to insert miniaturized instruments within a body cavity or structure, as in laparoscopic surgery or angioplasty. Abstract Background The possible advantage for weight loss of a diet that emphasizes protein, fat, or carbohydrates has not been established, and there are few studies that extend beyond 1 year. Figure 2 Mean Changes in Body Weight and Waist Circumference at Various Time Points. Thus, we recognized the need for a large trial that would be designed to overcome the limitations of previous trials and that would compare the effects of three principal dietary macronutrients. Transplant surgery is the replacement of an organ or body part by insertion of another from different human (or animal) into the patient.

The primary outcome was the change in body weight after 2 years in two-by-two factorial comparisons of low fat versus high fat and average protein versus high protein and in the comparison of highest and lowest carbohydrate content. Based on purpose: Exploratory surgery is performed to aid or confirm a diagnosis. (ClinicalTrials. Cosmetic surgery is done to subjectively improve the appearance of an otherwise normal structure.

The diets consisted of similar foods and met guidelines for cardiovascular health. The project staff of the National Heart, Lung, and Blood Institute also participated in the development of the protocol, monitoring of progress, interpretation of results, and critical review of the manuscript.
