Well we have another myth on our hands. Supposedly it is thought by many people, on the low carb diet, that you can actually have your calcium literally sucked out of your bones because of all the protein that you eat. Studies have shown that the only possible way for this to take place is if your body was not getting any other nutrients that it needs. While you are on the low carb diet, you body gets tons of nutrients from the fruits, vegetables, and meats that you eat. If you have done your homework, you will also know that while you are on a low carb diet, you should also be taking vitamin supplements as well. These vitamins help to give you the extra calcium and other nutrients that you will definitely need on the diet. Just be sure that you are taking the vitamins and you are eating the healthiest foods on the low carb diet so you can keep up with all your nutrients
