Gastric Bypass Diet – Diet After Gastric Bypass

Obesity could become a life threatening condition if your body mass index is more than 39.9. Often obesity becomes a disabling condition that necessitates emergency weight loss treatment. Standard dieting methods are usually ineffective in bringing down the body weight rapidly. An extremely obese individual might fail to melt the body fats through exercises, especially when obesity limits physical movements. A gastric bypass surgery is sometimes the best option for an obese person to reduce body weight. Often gastric bypass is the most viable long-term weight loss solution.

Gastric bypass is a surgical procedure that reduces the size of the stomach. A smaller stomach will make you full even by having small meals. By reducing your calorie intake naturally, gastric bypass treats obesity. After gastric bypass surgery, the diet of an individual undergoes major change. Your new diet should accommodate the needs of your newly created stomach.

Gastric bypass diet

To accelerate recovery after the gastric bypass surgery and for aiding repair and growth of cells, adequate amount of low fat proteins should be included in the diet. However, you should not consume more than 70 grams of protein per day. Often protein supplements such as whey protein are recommended after the surgery. Your physician might ask you to take protein supplements for about 1 to 2 weeks after the surgery. Small amounts of baked, grilled or broiled fish, chicken and lean meat could be included in the diet. Legumes, beans, skimmed milk and eggs could be part of gastric bypass diet.

Limit sugar intake

To prevent Dumping Syndrome, a common side effect of gastric bypass, sugar is excluded from gastric bypass diet. Avoid honey, maple syrup, molasses, corn syrup and all forms of simple sugar. Artificial sweeteners could be taken in small amounts.


Limited calorie intake after gastric bypass might increase the risk of nutrient deficiency. To prevent nutrient imbalance, multivitamin and mineral supplements should be taken everyday. You might need extra calcium in the form of calcium citrate supplements.

Phases of gastric bypass diet

Immediately after the gastric bypass, the patient lives on liquid diet for a few days. This is followed by a pureed diet, in which mashed fruits, vegetables, fish and lean meat, cereals cooked in milk, low fat yogurt, skimmed milk and cottage cheese are served. Gradually semi solid foods are introduced in the diet. Four to six weeks after the gastric bypass surgery, solid food items are included in the meals.
