The basics
Your sleeve holds much less than your stomach did, and hormone changes lower your appetite. You may not feel hungry, but skipping meals won’t speed up weight loss. It can leave you malnourished and slow your recovery.
Protein helps you heal and limits muscle loss. Eat it first.
Avoid refined sugar, which is high in calories and low in nutrients.
Sip through the day to avoid dehydration and constipation.
Avoid alcohol, and keep processed snack foods to a minimum.
Stage by stage
Daily goals from stage 2 on: 60 to 80 grams of protein and 56 to 65 ounces of fluid.
| Stage | When | What you eat | Tips |
|---|---|---|---|
| 1. Clear liquids | In the hospital and the first week | Water and other clear liquids, in small sips | Start with sips and increase slowly |
| 2. Full liquids | From day 7, for about 2 weeks | Thin liquids such as skim milk | The sample meal plan is about 550 calories a day |
| 3. Pureed foods | From day 21, for about 2 weeks | Smooth foods with no lumps, such as fat-free yogurt, mashed potatoes, blended beans and smooth soups | Eat small amounts 4 to 5 times a day |
| 4. Soft foods | From day 36, for about 2 weeks | Beans, cooked vegetables, fish and eggs | Move toward 3 small meals a day and a snack |
| 5. Regular diet | From day 50, for life | Lean meat, eggs, beans, low-fat dairy, vegetables and fruit, with whole grains filling no more than a quarter of the plate | Low fat, low sugar and smaller portions |
Mayo Clinic describes the same five stages: clear liquids, full liquids, pureed foods, soft foods and a regular diet (Mayo Clinic). Follow your nutritionist’s schedule for moving between stages.
Every day
Eating too much or too fast can cause reflux and vomiting.
Chew every bite thoroughly.
Drink 30 minutes before or after eating, not with your meal.
Don’t eat right before you go to bed.
Avoid candy, cookies, ice cream, table sugar, cake, honey, syrup, jelly, fruit juice and carbonated drinks.
Coffee is acidic and may trigger reflux.
Some foods may be hard to tolerate at first. Skip them and try again later. If you keep vomiting, can’t keep liquids down or become constipated, contact your care team.
For life
You take vitamin supplements for life after a gastric sleeve (Mayo Clinic). Your care team will tell you which ones and how much.
Your daily base, every day.
Commonly low after bariatric surgery.
