What does low carb do to your bones?
There is a lingering idea that eating low carb could result in osteoporosis, due to making blood acidic and leeching minerals from the bones.

However this theory has a few problems. For example, under normal circumstances the pH of the blood does not change depending on what diet you eat. The blood pH is tightly controlled within a very narrow span – or we’d die.

Testing the theory

More importantly this idea has been tested several times. A newly published study found the same thing as two earlier studies.

All three studies told a group of people to go on a strict low-carb diet (below 20 grams a day) and followed them for up to two years, comparing the results to a group on a high-carb diet.

Whether tracking markers of bone loss, or checking the bones with radiological methods (DEXA scans), the results were the same every time. Guess what?

Zero difference between the groups. Nothing happened to bone strength.

Time to let go of the myths

It’s high time to let go of the old acid-alkaline myth. Clearly bone strength is unaffected on a strict low-carb diet. The bones do fine.

Another idea is that high protein diets could negatively impact bones. This is probably not just wrong but the opposite of the truth. Bones are partly built by protein, and a recent study showed that women’s bones seem to get weaker on a low-protein diet.

Bones – like the rest of the body – need a sufficient amount of protein to stay strong. But carbs are not required.

"low carb could result in osteoporosis" This is one of the old chestnuts that rears it's head every now and again, usually spouted by an over weight dietitian. Whatever side of the fence a person is, even the LC naysayers agree we must have fats and proteins to live, end of. It is also a fact there is no such thing as an essential carbohydrate, end of. Everyone agrees with that as scientific facts, then many go onto to try and defeat their own argument, it's bonkers I tell ya.

Calcium metabolism is affected by vitamin D3 and K2 among other things. Both fat soluble.
