As you prepare for bariatric surgery, no doubt you have been told to keep your protein intake high. Current recommendations range from 60-120 grams a day, depending on your size. So, in order to eat 80 grams of protein in a day, you would have to intake 11 eggs, or a whole chicken, or ⅔ gallon of milk. You can see that will be difficult without the use of protein supplements that are easy to drink or add to your food.
After surgery, particularly in the first 2 months, your ability to eat or drink enough protein is limited. Your smaller size stomach “pouch” is a bit swollen from incisions so you need to be careful to have liquids for a few weeks and then move to pureed foods as your wounds heal, inside and out. During this time, you need help with protein intake by consuming protein supplements. As you progress through the first 6 months to a year, eating solid food, you still need to reach your protein goal, with the help of supplements.
In the first 2-3 months after surgery, a bariatric patient struggles to get all his/her protein needs in from these solid proteins, and so one must use some protein powders and drinks to reach a goal of an average 90-100 grams a day.
Not all protein powders are created equal. Research rates whey protein isolate the best in protein quality, since it contains more leucine, an amino acid that is responsible for stimulating muscle development. Soy protein, casein, and egg white are also beneficial choices. Check the quality and amount of protein in the supplement you choose to enhance your diet with your dietitian. Sometimes a product’s advertisements may seem too good to be true, and it may not be. Poor quality protein may be “spiked” with nonessential amino acids to increase the amount of grams of protein per serving, and at a lower price. Track your protein intake daily to be sure you reaching your goals for the best surgery outcome.
