Vitamin D and Fish oil and weight loss

Calories in and calories out don't seem to be working for me. My body seems to be holding on to the weight no matter what I do.

This is an article I've found:

Vitamin D and weight loss
I’m sure many of you have seen the “diet with dairy” ads launched by the American Dairy Council. Some studies have shown that weight loss does occur with an increase in calcium intake, while others appear to refute this. Since vitamin D is directly involved in calcium absorption, it stands to reason that vitamin D is also a factor in how the body regulates weight.

Moreover, people who have a reduced capacity to mobilize vitamin D often weigh more and have more body fat than those with full capacity. In the past 20 years multiple studies have shown a correlation between higher blood levels of vitamin D and leaner body mass.

To my thinking, what seems essential for us to understand here is the vitamin D connection with insulin resistance. Vitamin D deficiency may contribute to the wide set of disorders associated with metabolic syndrome (syndrome X), as well as to PCOS. In a study published in 2004, the authors saw a 60% improvement in insulin sensitivity in healthy, vitamin D replete adults — and concluded vitamin D was more potent than two prescription medications commonly used to treat type 2 diabetes! But the cadres of drug reps spread out across America are not likely to be reminding your healthcare practitioner about this study. They are not likely to have heard about it!

Clearly, vitamin D seems to be very important in regulating our weight, but we don’t yet understand the mechanism involved or how it relates to our environment and individual biochemistry. Still, there seems to be a correlation between rising rates of obesity and vitamin D deficiency. If you are having difficulty with insulin resistance or weight gain — or can’t keep the pounds off once you lose them — you may want to have your vitamin D levels checked by your healthcare practitioner.
