7. You have weak muscles
Proximal muscles are those which are aligned close to the center of your body, such as the biceps and quadriceps. These set of muscles are known for their bulk, since they take most part in ‘initiating a movement’.
Since they initiate movement, they hence require a great deal of calcium ions in the blood for contraction. Depleted calcium levels can interrupt the mechanism by much extent. Calcium deficiency can occur in many conditions, one of which is inadequate vitamin D levels in body.
Many affected people complain of frequent muscle aches and weakness. They report getting fatigued much earlier than before, and are rendered unable to carry heavy objects, or even move around. Muscle manifestations are the foremost ones in case of calcium deficiency, and this in turn occurs much more commonly in cases where vitamin D is not sufficient.
Hence, along with taking proper calcium-containing diet, it is also important for you to consume vitamin D. In case you do not get a chance to proper sunlight exposure or your vitamin D levels are too low, you are likely to be prescribed a supplement course by your doctor.
8. You’re overweight
Now this sign of vitamin D deficiency shall be the most undesirable one, yet it is inevitable. Inadequate vitamin D in your body can leave you with extra pounds of weight. So if you are putting on weight despite having a good diet, check if your diet actually contains all the nutrients you need, and not merely a portion of them.
In a study that included 4600 female participants over the age of 65, it was observed that those subjects who contained inadequate vitamin D levels gained 2 pounds more than their counterpart subjects.
Another such research work that supports our argument regarding ‘low vitamin D and weight gain’ can be demonstrated from the results of a study which were published in the American Journal of Clinical Nutrition, which states that in the pursuit of reducing weight, those women subjects who followed the schemed diet and exercise for weight loss and took vitamin D supplements as well, exhibited more pronounced results than their counterpart subjects.
Studies have also observed a link between insulin resistance and obesity to that of low levels of vitamin D.
