Calcium and Vitamin D for Obesity: A Review of Randomized Control Trials (RCT’s)

The human body is very complex, yet simple mechanism. The way in which cholesterol (fats), minerals, and vitamins contribute to the nutrients within the body range. The human body is made of millions of cells that are directed by DNA to make certain proteins, which then code for the insertion of amino acids (polypeptide chains). These amino acids then contribute to enzyme regulation and the production of hormones throughout the body. All of these components contribute to cell nutrients, the amino acids that our bodies are not capable of making must be consumed through foods. When the body does not consume the right amount of amino acid or vitamin supplement, it begins to become insufficient and incapable of ridding the body of toxic materials, as well producing a healthy immune system. In all, the way you eat, the amount of water consumed, and your ability to help the body rid unhealthy fats (toxins) by exercising and detoxification are the mechanisms for having a productive body.

Most Americans in the United States are considered to be obese. The body is made up of fat cells from the accumulation of cholesterol. Keep in mind, all fat isn’t bad fat. Yes, there are healthy fatty acids inside the body that contribute to the body’s overall energy consumption; hence; why one is able to exercise or simply keep the body in motion. Fatty acid cells are found in the muscles of cells and produced by lipoproteins. They are also referred to as adipose tissue. The accumulation of too many fatty acids cells contribute to obesity. Obesity is a condition that is considered to accompany an unhealthy lifestyle. It also slows the body’s circulation because not enough oxygen can pass through selectively permeable membranes. This in turn leads to blood clotting and obviously an accumulation of fatty tissue all over the body. Most people who are obese are consumers that cannot control their calorie intake. Calorie intake is the issue at hand in order to help produce a healthy lifestyle.

In the article I found entitled, “Calcium and Vitamin D for Obesity” researchers used a review of randomized control trials (RCT’S) to show if more calcium and vitamin D intake help contribute to weight loss. They used the trial with women only. Among these women, there hypothesis consisted of the idea that calcium intake during weight loss should result in greater fat loss. The fat percentage measured on the body is the total accumulation of fat in the body. The higher the percentage the higher the risk of heart disease. Also, weight loss was only considered in this trial in relation to BMI and fat percentage. Researchers were not simply intrigued by the number on the scale. They found that calcium and vitamin D support does not support calorie intake, but can suppress appetite. Researchers also reported higher calcium was much better than moderate calcium accelerating weight loss over time; though, differences in fat mass were not significant. On the other hand, vitamin D supplementation presented no effect on changes in body weight, waist-hip ratio, or percent fat mass. Overall, the idea that calcium and vitamin D contribute to weight loss was highly insignificant. I do believe the study may have been done broader and more biological aspects should have been taken into consideration. The study was only used with women, but the calcium or vitamin D present prior was not taken into consideration. These trials could have very well been witnessed on calcium deficient individuals, which then places the trial under high scrutiny. In other words, maybe this randomized trial should have been a conditioned group of women to measure such bodily contributions. Do you agree?
