What Is Pouch Reset And How Does It Work?

What Is Pouch Reset, And How Does It Work?

A friend of mine wanted to try the pouch reset, and neither of us knew what it involved or who it was for. So I looked into it.

Here is what the plan involves, what the evidence says, and what to do instead if you are regaining weight after bariatric surgery.

What is Pouch Reset?

A pouch reset is a short, restrictive diet that some people try after bariatric surgery, usually when they start regaining weight. It is not a medical treatment, and it did not come from surgical guidelines.

The best-known version is the "5-day pouch test," which moves from clear liquids to solid food over five days. Other versions stretch the same stages over about 10 days.

The idea is that eating this way will "tighten" or shrink a stomach pouch that has stretched. The plan works by sharply cutting calories for a few days.

The 5-Day Pouch Reset Meal Plan Stages-

1. Day First Meal: Clear liquids only, with no solid food.

Water
Decaf tea
Decaf coffee
Broth
Popsicles (Sugar-free)
Jell-O (Sugar-free)

2. Day Second Meal: Full liquids, still with no solid food.

Pudding (Sugar-free)
Vegetable soup
Sorbet (Sugar-free)
Very thin oatmeal
Non-fat ice cream (Sugar-free)

3. Day Third Meal: Pureed foods with a smooth consistency.

Hummus
Protein Soup (no chunks)
Cottage cheese (Low fat)
Scrambled eggs
Stay away from meat
Almond milkshake
Coconut milkshake

4. Day Fourth Meal: Soft foods that are easy to digest. Skip raw vegetables and hard fruits.

Soft vegetables
Soft ground chicken or beef
Soups
Scrambled eggs
Cooked Salmon and tuna
Mashed fruits like avocados, bananas, grapes

Day Fifth Meal: Healthy solid foods return, with protein first, then vegetables, in small portions.

Consume healthy protein-rich food
Eat a small amount of food as the size of your fist
Try to eat lean protein
Chew every bite of food for easy digestion
Avoid drinking with meals; drink between them instead

Does A Pouch Reset Work?

There is no good evidence that it does. We found no published studies showing that a few days of liquid and pureed food shrinks a stomach pouch.

The pouch reset diet appeals to a real fear: that weight regain means the pouch has stretched. Early after surgery, the pouch feels tight partly because of swelling, and that tightness eases as it heals.

Your capacity to eat does grow over time. MedlinePlus advises not eating more than your provider recommends, so you do not stretch the pouch.

Weight regain is mostly driven by what you eat, how much, and how often, along with activity and other health factors. A five-day plan does not change those habits on its own.

Any weight lost during a pouch reset comes from eating very little for a few days. Once larger meals return, so does the weight.

Because the idea is not discussed in the medical literature as an evidence-based treatment, talk to your bariatric team before trying it, especially if you have diabetes or take medication.

Reviews From People Who Try Pouch Reset

Which Diet Should Flow After The Bariatric Surgery

Follow the eating plan your surgical team gives you, with support from a registered dietitian.

Gastric Bypass Diet

Gastric bypass makes the stomach much smaller and changes how food moves through your gut. MedlinePlus recommends these habits after surgery:

Eat Slowly- Take at least 20 to 30 minutes to eat a meal. Pain under the breastbone or vomiting can be a sign you are eating too fast.
Eat Small Meals– Eat about six small meals a day instead of three big ones, and avoid snacking between them. Small plates and utensils help with portions.
Drink Water Between Meals- Drink up to 8 cups (2 liters) of water or other calorie-free liquids a day, in small sips. Do not drink while eating or for 30 minutes after a meal, since liquid fills you up.
Chew Food Properly- The opening from the pouch to the intestine is narrow. Food that is not chewed well can block it, so chew each bite until it is smooth.
Eat High-Protein Foods- Protein may be the most important food early on. Good choices include skinless chicken, fish, eggs, beans and low-fat dairy.
Stay Away From Fat and Sugar Foods– Avoid foods high in fat and sugar, and drinks with sugar, fructose or corn syrup. These can cause dumping syndrome.
Take Recommend Supplements – You will need vitamins and minerals for the rest of your life. MedlinePlus lists a multivitamin with iron, vitamin B12, and calcium with vitamin D. Follow your team's exact plan.

Results of a Gastric Bypass Diet

The diet helps you heal, adjust to smaller meals and support your weight loss.

If you return to old eating habits after surgery, you may not lose all your excess weight, or you may regain weight.

Risks of Gastric Bypass Diet

Problems often come from not following the plan, such as eating large meals or foods you should avoid.

Dehydration- You cannot drink with meals, so it is easy to fall short. Sip fluids steadily between meals.
Constipation- Low activity and too little fluid or fiber can cause constipation.
Dumping Syndrome- Food that moves into the small intestine too fast can cause nausea, vomiting, dizziness and diarrhea. Eating too fast or too much, sugary or fatty food, and poor chewing all raise the risk.
Blocked Entrance of Your Stomach Pouch- Food can block the pouch opening. Call your doctor if you keep vomiting, feel nauseated or have belly pain.
Weight Gain or No Weight Loss- If you are regaining weight or not losing, contact your surgical team or dietitian.
