Bone Broth Recipe


  • 1kg of bones (Whenever possible choose bones from grass fed cattle, free-range poultry and wild fish. Bone can be purchased or saved from leftovers and frozen)
  • 1 onion, chopped in wedges
  • 2 carrots, chopped into large roundels
  • 2 sticks of celery, coarsely chopped
  • 2 Tbsp of raw, unfiltered apple cider vinegar
  • 1 Tbsp of salt
  • 1 tsp of whole peppercorns
  • Other herbs and spices



  1. (Optional) For additional flavour, roast the bones in the oven at 180°C for 30 minutes prior to adding to the broth.
  2. Place bones in pot and pour 2L cool water over the bones.  Add raw, unfiltered apple cider vinegar. Allow the bones to marinade in the vinegar for 30 minutes to increase nutrient availability from the bones.
  3. Add vegetables and dried herbs.
  4. Bring to the boil over medium heat.
  5. Reduce heat to low. Once simmering, cover with a lid and allow the broth to continue to simmer for 2 hours.
  6. Skim off any impurities on the surface.
  7. Add enough water to restore broth to original level.
  8. Bring back to the boil.
  9. Reduce heat to low. Once simmering, cover with a lid and allow the broth to continue to simmer for 6-10 more hours.
  10. When 30 minutes are remaining, add any fresh garlic or herbs.
  11. Remove from heat and let cool for 5 minutes, then strain (discard all solids).
  12. Store in small containers or an ice tray in the freezer for later use. One ice cube of reconstituted broth is the perfect size for a coffee mug.


Note: The consistency of the broth when cooled should be similar to jelly.

Side effects of low carbohydrate high fat (LCHF) eating

By Tamzyn Murphy Campbell

Many people experience certain common side effects when following low carbohydrate high fat (LCHF). These include:

  1. Keto “flu”: during the first week of starting LCHF some people experience aches and pains, headaches, lethargy, nausea, brain fog and/or irritability.
  2. Constipation
  3. Fatigue/lethargy
  4. Muscle aches/cramps
  5. Headaches
  6. Signs of low blood pressure, including heart palpitations, dizziness and nausea.

The good news is that the root cause of these symptoms is the same and completely rectifiable.


What’s behind the symptoms?

When you are eating a conventional high carbohydrate diet, your body is producing quite a lot of insulin. Insulin is produced by the pancreatic beta cells in response to glucose or “sugar” entering the bloodstream after digestion of a carbohydrate-containing food or beverage. Insulin’s job is to remove “sugar” from the bloodstream and put it into the cells, where it’s turned into energy or stored. One of the side effects of insulin is to reduce the kidneys’ excretion of water and certain electrolytes or minerals (namely, sodium or ‘salt’, magnesium and potassium) [1-3].

Conversely, when you eat a low carbohydrate diet the amount of insulin that your pancreas produces is dramatically reduced, as there’s much less carbohydrate entering the blood stream from your diet. The lower insulin level results in increased excretion of water, sodium, magnesium and potassium from the kidneys.  This loss of fluid often lowers blood pressure and can cause dehydration if the fluid is not replaced by drinking more. The resulting symptoms can include headaches and symptoms of low blood pressure, including fatigue/lethargy, heart palpitations, dizziness and nausea. The loss of sodium, potassium and magnesium can cause muscle aches, pains and cramps, as well as irritability. [1]


How to fix it

  1. Drink plenty of fluids (to thirst)
  2. Add salt to your food
  3. Drink a cup of bone broth every day
  4. Take a magnesium supplement, which provides 400 mg of elemental magnesium daily. Choose a supplement that contains magnesium in the form of a magnesium chelate (elemental magnesium bound to an amino acid), such as magnesium glycinate, for optimal absorption.


Important note: Should drinking more fluids, consuming more salt, drinking bone broth and taking a magnesium supplement not improve your symptoms, it is important that you see your doctor as soon as possible.
