Purpose
Prolonged fasting may increase the organic response to trauma. Carbohydrate-based drinks have been tested and they may reduce insulin resistance. No study so far has aimed to examine the possible benefits of whey protein drink in the composition of preoperative drinks.

Primary Outcome Measures:
- insulin resistance [ Time Frame: Homa-IR will be assessed in two time points: baseline (2-3 h before operatio) and 24h after operation ]Insulin resistance will be assessed by Homa-IR
Secondary Outcome Measures:
- acute-phase response [ Time Frame: Assays for the various acute-phase proteins will be done 2-3h before operation and 24 h after the operation ]Assays for albumin, pre-albumin, C reactive protein and α-1-acid glycoprotein

Placebo Comparator: water
Patients will receive water 3h before operation in the same volume of the study group

Dietary Supplement: whey protein plus carbohydrate drink
The CHO-P group received 474 ml (evening drink) or 237 ml (3h prior to operation drink) of a solution containing 14% whey protein (100% lactoalbumin), 86% carbohydrates (45% hydrolyzed corn starch and 55% sucrose) and 0% lipids (Resource® Breeze - Nestlé, São Paulo, Brasil)

Detailed Description:
The patients will be randomized into two groups: the carbohydrate-protein group (CHO-P) and the control group (CO). The patients will reeive a specific drink to their group on the evening prior to surgery and three hours before the operation. The CHO-P group will receive 474 ml (evening drink) or 237 ml (3h prior to operation drink) of a solution containing 14% whey protein (100% lactoalbumin), 86% carbohydrates (45% hydrolyzed corn starch and 55% sucrose) and 0% lipids (Resource® Breeze - Nestlé, São Paulo, Brasil) and the CO group will receive the same volume of water.
Outcome measures On the day of the surgery and on the first postoperative day blood samples will be collected for glucose, insulin, triglycerides, albumin, pre-albumin, CRP, and α-1-acid glycoprotein (α-1-GA) assays. HOMA-IR will be calculated
