how does chromium picolinate work?

After eating, the human body secretes the hormone insulin. In general, the primary function of insulin is to transport glucose to the body cells in order to provide energy that facilitates cell functioning. It is speculated that chromium picolinate works by stimulating the activity of insulin, thus significantly aiding the body glucose and fat metabolism, managing the breakdown of glucose and fat

chromium somehow works to increase sensitivity of insulin receptors
improved insulin efficiency causes an increase in the production of seratonin, which subsequently reduces appetite.
chromium picolinate will increase and even tone lean muscle mass during the weight loss process.

In the absence of exercise, it may even cause weight gain.
