There is a category of GLP-1 day that most people who take the medication know well: the day when eating solid food is simply not going to happen. Nausea, sensitivity, complete absence of appetite — for whatever reason, the idea of chewing and swallowing a meal is unappealing to the point of impossibility. On these days, liquid nutrition is not a backup plan; it is the plan.

Chicken bone broth sits at the top of the liquid nutrition hierarchy. A well-made bone broth — simmered 12–18 hours until it gels when cold — provides approximately 10g of protein per cup, rich in collagen-derived glycine and proline that support gut lining integrity and joint health. It is warm, deeply savory, and requires almost zero effort to consume: pour into a mug, heat for 60 seconds, drink. That's it.

The slow cooker method requires essentially no active time. You add the ingredients before bed, set it to low, and by morning the kitchen smells remarkable and the broth is done. Strain it, let it cool, skim the fat, and portion into containers. Freeze what you won't use this week. You now have a GLP-1 emergency protein supply that will be there whenever you need it.

Why This Works on GLP-1

Collagen is the most abundant protein in bone broth. When bones are simmered with an acid (apple cider vinegar) over many hours, collagen breaks down into gelatin, which dissolves into the liquid. A properly made broth will solidify into a jiggly gel when refrigerated — this is the sign of high collagen content, not a defect.

Glycine, the primary amino acid in collagen, has documented benefits for gut health — particularly important for Zepbound or Ozempic users: it supports the integrity of the intestinal lining, which can become more sensitive during GLP-1 use. The gut-health emphasis in GLP-1 nutrition is grounded in this mechanism — supporting the gut lining while the medication does its work.

For days when even a small meal triggers nausea, sipping warm broth delivers meaningful protein (10g per cup) in a format that requires almost no digestive effort. It is absorbed quickly, gently, and completely.

Ingredients (makes approximately 2 litres)

  • 1 chicken carcass (from a roasted chicken) or 1kg (2.2 lb) chicken backs, wings, and necks
  • 2 medium carrots, roughly chopped
  • 2 celery stalks with leaves, roughly chopped
  • 1 medium onion, halved (no need to peel)
  • 4 garlic cloves, smashed
  • 2 tablespoons apple cider vinegar
  • 1 teaspoon whole black peppercorns
  • 2 bay leaves
  • 4–5 sprigs fresh thyme or 1 tsp dried
  • Cold water to cover (approximately 2.5–3 litres / 10–12 cups)

Instructions

  1. Optional roasting step. For deeper, richer flavor, roast the bones at 200°C (400°F) for 30 minutes until golden brown before adding to the slow cooker. This step is optional but produces a noticeably better broth.

  2. Add everything to the slow cooker. Place bones, vegetables, garlic, apple cider vinegar, peppercorns, bay leaves, and herbs in the slow cooker. Pour cold water over until everything is just submerged.

  3. Let the vinegar work. Before turning on the slow cooker, let the bones sit in the cold water with vinegar for 30 minutes. The acid begins extracting minerals from the bones before heat is applied.

  4. Cook on low for 12–18 hours. Set the slow cooker to LOW. The broth should barely simmer — you want a very gentle heat that extracts collagen slowly. Boiling rapidly produces a cloudy, less gelatinous broth.

  5. Strain. After cooking, strain the broth through a fine-mesh sieve into a large bowl or pot. Discard the solids. The liquid will be golden-brown and fragrant.

  6. Cool and skim. Let the broth cool to room temperature, then refrigerate overnight. The fat will solidify on the surface and can be lifted off cleanly with a spoon. The broth beneath should be semi-solid (gel-like) — this is the sign of collagen-rich broth.

  7. Portion and store. Store in 240ml (1-cup) portions in the fridge for up to 5 days. Freeze the rest in individual portions for up to 6 months. Ice cube trays make small frozen portions perfect for cooking use.

Storage & Usage Guide

Fridge: 5 days in sealed containers. The gelled texture is normal — it liquefies when heated. Freezer: 6 months. Freeze in 240ml cups for direct drinking, and in 60ml ice cube portions for cooking use. Direct drinking: Heat 1 cup, season with salt and optional lemon juice, sip from a mug. Cooking base: Use instead of water or commercial broth for soups, stews, grains, and sauces.

Practical Notes

The gel test. Refrigerate a small amount overnight after cooking. If it sets to a solid or semi-solid gel, the broth is rich in collagen. If it stays completely liquid, simmer longer and/or add more bones next time.

Chicken feet for maximum gelatin. Adding 2–3 chicken feet to the pot significantly increases gelatin content. They are inexpensive and available at most butchers and Asian supermarkets. They add no flavor — only collagen.

Commercial broth is not bone broth. Most commercial chicken broth has been cooked for 30–60 minutes, not 12–18 hours, and contains very little collagen. It is a soup base, not a collagen source. The protein content is also much lower (typically 2–3g per cup vs. 10g in homemade).

Season after, not during. Do not salt the broth while cooking. The long simmer concentrates flavors; what seems mild raw will be quite salty after 18 hours. Season each cup individually when serving.

Frequently Asked Questions

What if my broth doesn't gel after refrigerating — did I do something wrong?
A broth that remains liquid after refrigerating has lower collagen content, usually because the simmer time was too short or the bones had less connective tissue. The broth is still safe and nutritious — it simply contains less gelatin. To improve gelation next time, simmer for the full 18 hours, add 2–3 chicken feet (available at butchers and Asian supermarkets), or include more joint-heavy bones like wings and backs rather than just a carcass. Even a liquid broth still provides meaningful protein from the collagen that did extract.
Can I drink bone broth on injection days when solid food is not possible?
Yes — sipping warm bone broth is one of the most practical strategies for injection days or other high-nausea periods. Heat one cup, season lightly with salt and optionally a squeeze of lemon juice, and sip slowly from a mug over 20–30 minutes. The glycine in collagen has a mildly calming effect on gut tissue, and the warmth can help ease digestive discomfort. Each cup delivers 10g of protein with almost no digestive effort, making it an ideal nutrition strategy when eating solid food is not viable.
How do I substitute for a chicken carcass if I don't have one on hand?
Chicken backs, wings, and necks are the best substitutes — they are sold cheaply at most butchers and supermarkets and are often even higher in collagen than a standard carcass. Use approximately 1kg (2.2 lbs) of these parts in place of a single carcass. Alternatively, some stores sell "soup bones" or "stock packages" specifically for this purpose. Avoid using only chicken breast or thigh meat without bones — without the connective tissue and bone marrow, the broth will not gel and the protein content will be much lower.
Is it safe to simmer the slow cooker overnight unattended?
Yes — this is by design. Modern slow cookers are built to run safely on low heat for 18–24 hours unattended. The low setting maintains a temperature below a rolling boil, which is actually preferable for bone broth because excessive heat produces a cloudy, more bitter broth. Place the slow cooker on a heat-safe surface away from flammable materials, ensure the lid is seated properly, and proceed with overnight cooking without concern. If your slow cooker runs particularly hot on low, check at the 12-hour mark and switch to warm if the broth is already gelatinous.
How much broth should I drink per day, and when is the best timing?
One to two cups per day is a practical and effective amount for GLP-1 users using broth as a protein supplement. Timing depends on your pattern: some users drink a cup in the morning in place of breakfast on low-appetite days, others use it as a between-meal gap-filler when solid food is not appealing. On injection days, sipping a cup 1–2 hours after your injection can help manage nausea while still providing protein. There is no strict upper limit, but beyond 3 cups daily, you will likely reach adequate protein through other means and the broth becomes less necessary.
