What is the Goal of Stage 4?

Stage 4 shifts the focus from rebuilding to cleansing. While continuing to increase nutrient-dense “building” foods, you’ll start adding gentle detoxifying foods—only when your gut is ready.

Foods for GAPS Introduction Diet Stage 4

Continue with foods from Stage 1-3, gradually increasing the amounts, and slowly introduce:

• Roasted & lightly sauteed meats
• Cold-pressed oils
• Fresh Pressed Juice & GAPS Shakes
• Baked Goods

Continuing with Stage 1-3 foods

• Meat Stock – Meat stock and soup should still make up the bulk of your meals, Dr Natasha recommends consuming lots (5 cups daily for adults, 3 for children, it can be in soups and stews). Meat stock provides the essential building blocks for the rapidly growing of cells to heal and seal the gut lining (Gut and Physiology Syndrome, p169).
• Animal Fats – Continue having plenty of animal fats in every meal, increasing to body tolerance. The fat content will regulate the blood sugar levels and control cravings for carbohydrates (source).
• Egg Yolks – Continue to add egg yolk to your meals each day.
• Vegetable ferments – Continue increasing the amount and variety of fermented foods

Roasted & lightly sauteed meats

The introduction of roasted and lightly sauteed meats signifies progression to harder-to-digest cooking methods, Dr Natasha recommends avoiding overly browned or burnt portions of meat, as these can be more challenging for digestion.

If any signs of digestive regression occur, it may be necessary to return to softer, slow-cooked meats on earlier stages until more healing has occurred.

Introducing Cold-Pressed Oils

Gradually add cold-pressed oils like olive and avocado to meals, dips, and dressings. Dr. Natasha recommends starting with just a few drops per meal, slowly increasing to 1–2 tablespoons. While not needed with every meal, these oils are excellent for making homemade mayonnaise and dressings.

Fresh Pressed Juice

Fresh vegetable juices support detoxification and deliver easily absorbed nutrients—typically within 20–25 minutes. Because they require minimal digestion, juices provide a fast, concentrated source of vitamins, minerals, and antioxidants.

Dr. Natasha recommends starting with a few spoonfuls of diluted carrot juice from organic carrots. Use a chewing motion to stimulate digestion, and gradually increase to one cup per day as tolerated (Gut and Physiology Syndrome, p. 174). Once carrot juice is well tolerated, you can introduce other vegetables like celery, cabbage, lettuce, cucumber, and beetroot.

Juices oxidize quickly, so drink them fresh—ideally on an empty stomach, 20 minutes before or 2 hours after meals. While juicing helps remove toxins naturally and gently, it’s a supplement, not a meal replacement, as it lacks the full range of essential nutrients.

Try a GAPS Shake

Once juice is well tolerated, introduce a GAPS Shake—a blend of fresh juice (no pulp), 1–2 pasture-raised eggs, and a healthy fat like sour cream, yogurt, or coconut oil. First introduced in Stage 2 for constipation, they’re commonly added in Stage 4.

GAPS Shakes are easy to digest, nourish the body quickly, and support detox, bile flow, fat digestion, and even gallstone removal. Adding yogurt or sour cream also boosts probiotic intake. While powerful, GAPS Shakes should supplement—not replace—a balanced diet.

GAPS Diet Baked Goods

Stage 4 introduces GAPS-friendly breads, muffins, and crackers made from fermented nuts or seeds, eggs, healthy fats, salt, and sometimes vegetables. This is an exciting milestone, but as Dr. Natasha advises, introduce baked goods slowly and increase gradually while watching for signs of intolerance (Gut and Physiology Syndrome, p. 174).

Treat these as occasional foods—not staples—and use them as a vehicle for healthy animal fats, like butter or liver pate on a cracker.

When to move to the next stage?

Move to the next stage only when you can comfortably tolerate all foods from the current stage, meaning you experience no digestive symptoms.

If any digestive symptoms reappear, it indicates that you may be moving too quickly for your body to heal. In such cases, stop the new food you’ve introduced and wait 24 hours for any symptoms to improve. If they do not improve, revert to the previous stage for a few days before attempting to reintroduce the new food again.

The Dance

Healing isn’t linear. It can be like a dance, one step forward, two steps back. There’s no particular timeline or way your healing journey is “supposed” to look like. This is your individual journey!

During the healing process, your body may feel safe to release stored toxins, and this may lead to the return of previous symptoms or even new symptoms.

Dancing between intro stages is very common. Stay consistent with small steps every day, and progress will happen!

How to Prepare for Stage 4?

• Cooking methods – Learn and practice stage 4 cooking techniques: boiling, simmering, fermenting, stewing, casseroles, juicing, sauteing, light frying, and the addition of baking, roasting, and sauteing.

• Food Prep – Continue preparing vegetable ferments by experimenting with new flavors and gradually expanding your variety. Also, prepare larger quantities of dishes to freeze for future meals or reheat for another occasion. Try these time-saving tips for busy moms!

What to Eat in a Day During GAPS Introduction Stage 4?

Most of your meals should continue to consist of meat stock-based meals, soups, stews, casseroles or meat stock served on the side. Here is a sample meal plan:

• Wake up: Fresh-pressed juice or GAPS Shake
• Breakfast: Scrambled eggs cooked in ghee + sauerkraut + a cup of meat stock
• Lunch: Creamy Chicken and Leek Soup + sauerkraut
• Dinner: Oven-baked pork ribs + roast vegetables + sour cream for dipping
• Snacks: Mug of meat stock, avocado, yogurt, GAPS Shake

There is no restriction on the amount of food you eat; eat when you are hungry. You may need to eat 5-7 meals a day.

GAPS Introduction Stage 4 Tips

• Reheat meat stock and meals in a saucepan on the stove top or in the oven. Do not use a microwave as it destroys the nutritional benefits of the food.

• Plan activities to manage detoxification and die-off symptoms. As bacteria changes happen in the body, you might experience some uncomfortable symptoms, this is normal and symptoms vary from person to person. To help your body detox and feel better, you can try Epsom salt baths, enemas, and dry brushing.
