Vitamin D deficiency (hypovitaminosis D) is typically diagnosed by measuring the blood concentration of the 25-hydroxyvitamin D (Calcifediol, Calcidiol), which is a precursor to the active form of the 1,25-dihydroxy-vitamin D (Calcitriol) compound.
The blood concentration of 25-hydroxy-vitamin D reflects vitamin D produced in the skin as well as vitamin D acquired from the foods and has a relatively long circulating half-life of 15 days. It does not, however, reveal the amount of vitamin D stored in other body tissues and organs (muscles, liver, bones etc).
For many people, the symptoms of vitamin D deficiency are subtle and hard to recognize. But, even without obvious symptoms, too little vitamin D can pose health risks. Low blood levels of the vitamin D over short or long time, have been associated with the many symptoms.
Hypovitaminosis D can be caused by several factors like inadequate nutritional intake of vitamin D, inadequate sunlight exposure (UVB rays), disorders that limit or prevent vitamin D absorption, conditions that impair the conversion of vitamin D into active vitamin D forms including certain liver, kidney, and hereditary disorders.
Vitamin D is also know as 'sunshine vitamin', since human body can produce it on it's own with the help of UVB light - therefore it is not strictly essential dietary vitamin.
Consuming foods rich in vitamin D with regular, but not prolonged (at least not unprotected) sun exposure is more than enough to prevent vitamin D deficiency.
Unfortunately, not all the foods we eat have vitamin D in substantial quantities. Actually, vegetables and fruits contain no vitamin D.
There are numerous effects of increasing vitamin D daily intake, supplementation included. Vitamin D supplements are, for example, used to prevent osteomalacia or rickets, but the evidence for other benefits of vitamin D supplementation in the general population are inconsistent.
The best evidence of vitamin D supplementation benefits are for bone health (babies, children, adults, elderly people) and a decrease in mortality in elderly women (after menopause).

To function properly, human body needs approximately one third of saturated fats, one third of monounsaturated fats and one third of polyunsaturated fats. Although saturated fats are needed just as monounsaturated and polyunsaturated fats, because they are consumed in western nutrition much more than other fats, saturated fats are often called 'bad fats' and monounsaturated and polyunsaturated fats are called 'good fats'.

Muscle Hypertrophy and Hyperplasia or how muscles grow is something that many trainees see as 'go to the gym, lift a little bit (in order not to bulk up too much), have beach body in no time'.
Avoiding gym workouts and exercising in general because of 'fear' from muscles is just an excuse for not working out at all. It takes proper nutrition and plenty of smart workouts for long time to achieve desired body and look, not to mention self-discipline and sacrifices...
