Patients are required to consume 80-100 grams of protein after surgery, 60-80 for diabetic and kidney patients. It can be challenging to take in this much protein on a daily basis through food alone. Dr. Yadegar recommends 1-2 protein drinks after weight loss surgery per day to supplement your intake. Ready-to-drink protein shakes and protein powered scoops can range from 140-500+ calories. If you’re going to add fruit or other mix-ins, select a lower calorie option to start with – because all calories count!
