One of the latest exciting science studies has been on Vitamin D and weight loss. Researchers from the University of Minnesota put together a diet study with 38 obese men and women. The results revealed a distinct correlation between vitamin D and weight loss. Dr. Shalamar Sibley, as head of the study, said those that followed the diet plan without any supplementation, lost about half a pound less than those who supplemented with Vitamin D.
Although not radical in the amount of weight lost, it seems to have been significant enough for scientists to want to know if there may just be a possibility that a deficiency in Vitamin D causes obesity, or whether obesity itself causes the vitamin D deficiency. So we can't all rush out and start taking Vitamin D supplements and expect to lose a whole lot of weight. Rather, we need to wait on subsequent studies that will reveal the exact qualities of Vitamin D when it comes to losing weight!
However, what is the most encouraging part for me of what is known, is that Vitamin D, through photosynthesis and the sun's UVB rays, in conjunction with calcium, helps us to properly assimilate our food and regulate normal blood sugar levels. With a lack of calcium, which is actually often brought about due to a shortage of vitamin D, our bodies will increase the production of synthase, which is a fatty acid enzyme that coverts calories into fat. It is this increased synthase production, sometimes thought to be as much as 500 percent, that is believed to be the link between low levels of vitamin D and obesity. Hence, focussing on increasing Vitamin D and weight loss seems worth exploring.
Scientific research has really only just begun to scratch the surface of the role Vitamin D plays in the overall health status of us humans. It is only in the last few decades that enough research has been done to raise the interest sufficiently enough that many different research teams have started on Vitamin D projects. Results such as that published in the Archives of Internal Medicine, where 75% or more of American teens and adults have been found to be deficient in vitamin D, together with the fact that deficiency is linked to many illnesses including the serious ones of cancer, diabetes and heart disease, definitely gets people keen to know more about Vitamin D health benefits.
Another clinical study, conducted in April 2000, revealed that patients who were bound to wheelchairs because of chronic fatigue and body weakness became mobile after just six weeks of supplementation with 50,000 IU of vitamin D per week. Other studies including those with different types of cancer, heart disease or diabetes, have shown and continue to show remarkable healing results when vitamin D levels are boosted sufficiently.
Although current guidelines are somewhat confusing with their different suggestions of daily supplements ranging anywhere from 400 and 1500 IU, recent research is suggesting that these levels may be too low. Getting between 4,000 and 10,000 IU a day will have a much more therapeutic effect, boosting health and fending off disease. The most natural and healthiest way to get Vitamin D is through direct access to the sun's UVB rays, without letting yourself get sun burnt. Just 10 - 20 minutes per day in the midday sun, without any sun protection, will allow your skin time to create the equivalent of about 5000 IU's vitamin D. If access to the outdoors and sufficient sunshine is not possible for any reason or through choice you wish not to be exposed to the sun, supplementation for vitamin D3 is rather easy and not very expensive at all.
A Vitamin D blood test is highly recommended prior to boosting your levels though, as you may find they are perfectly fine! Once you know what the status is your vitamin D levels are, you can embark on a supplementation program to assist with weight loss.
According to the National Institute of Health, taking supplements that contain both vitamin D and calcium can assist in weight loss programs. However, scientists are not yet agreed on whether weight loss programs should include both Vitamin D and calcium or just vitamin D.
What they do say, is that although vitamin D might not help you lose weight on its own, increasing your vitamin D intake could support your weight loss efforts while enhancing your overall health. Even if weight loss doesn't happen, the bonus will be the boost for strong bones and osteoporosis prevention, a stronger heart and immune system, amongst other benefits. Needless to say, weight loss will almost always need to include a healthy diet and good exercise. Vitamin D alone is definitely not the miracle cure!
So, if you decide to go ahead and take vitamin D supplements, please be very aware that there is such a thing as vitamin D toxicity. An excessive amount of vitamin D may induce nausea and vomiting, loss of bone density and bone breaks, plus other complications. So it is not advisable to take more than 2000 IU per day without prior consultation with a health practitioner.
In a 2010 study from the American Journal of Clinical Nutrition, researchers studied 126 overweight women, all of whom were followed for six months. Their conclusion reported that boosting your levels of vitamin D, as well as your intake of dairy-derived calcium, may increase the likelihood of losing weight, especially while dieting.
Even though vitamin D is found in some foods such as oily fish and fortified cereals and milk, taking supplements may be a more reliable means of increasing your vitamin D levels in the effort to promote weight loss. Exposure to the sun if possible, is also a great means of boosting your Vitamin D levels.
According to a 2007 study reported in the Archives of Internal Medicine on 36,282 postmenopausal women who were assigned to receive 400 IU of vitamin D and 1,000 mg of calcium in supplement form or a placebo daily, Vitamin D may help thwart the weight gain that often occurs in middle-aged women. After three years of Vitamin D and calcium supplement-taking, those participants who had skimped on calcium prior to the study were found to be 11 percent less likely to gain weight, compared to those assigned to a placebo.
Besides losing weight, Vitamin D may provide enhanced benefits to just weight loss. In tests on 63 overweight or obese women assigned to a weight loss program, as reported in a 2007 study in the American Journal of Clinical Nutrition, scientists discovered that those who took 400 IU of vitamin D and 1,200 mg of calcium in supplement form daily during the course of their 15-week diet had greater improvements in their cholesterol levels, compared to those given a placebo for the same time period.
