    After RNY Gastric Bypass Surgery

    Dieting after gastric bypass surgery is broken up into four phases, but can vary depending on physicians. Two days immediately following gastric bypass surgery, physicians want to let your new stomach, which will be the size of a walnut, heal by not eating anything. Along with the diet plan you will be on a vitamin regimen to help offset nutrition you are lacking.

    Phase 1 Dieting

    After letting your new stomach heal, you will be able to sip clear liquids. If you take clear liquids well (water, sugar-free jello, broth, apple juice) then you will be moving on to the second stage of gastric bypass diet.

    Phase 2 Dieting

    Since your stomach is smaller you will start with small amounts of semi-liquids that will incorporate more nutrition. Liquids like skim milk, carnation instant breakfast, diluted oatmeal or potatoes, etc. You will be advised to consume slowly, and in small quantities. You will start consuming 2 or 4 ounces per meal, then move up to 4 or 6 ounces per meal. In order to prevent dehydration you will be advised to consume water and water-based liquids throughout the day.

    Tip: One of the common side effects is dumping syndrome after gastric bypass. But one way to combat this is by avoiding liquids and foods that are high in fat, sugar or contain alcohol.

    Phase 3 Dieting

    After sipping liquids all day you will be relieved to find the next stage includes solid foods. You can expect things like cooked eggs, crackers, bread, cottage cheese, canned chicken and more. Your physician will likely instruct you to consume 5 or 6 small meals per day of about 6 ounces each. Eating and drinking slowly, you will take about 30 minutes to consume a meal. After your physician is satisfied with your progress you will move on.

    Phase 4 Dieting

    The last phase of rny gastric bypass diet will include the much needed protein. You will be adding, fish, chicken, turkey, beans, eggs whites, etc. By adding these protein rich foods, you will help to heal after surgery and prevent hair loss. Hair loss is a common side effect and can be avoided by consuming more protein.

    Tip: To speed up weight loss, it’s always advised to limit the amount of fat that you consume. Foods like mayonnaise, pie, butter, peanut butter, fried foods of any kind, potato chips, all have excess fat that can slow your weight loss. Your goal is to consume enough fats to satisfy your nutrition without overdoing it; aim for no more than 40 grams per day.
