According to these studies, a protein intake around 30% of calories may be optimal for weight loss. This amounts to 150 grams per day for someone on a 2000 calorie diet. You can calculate it by multiplying your calorie intake by 0.075.
When we look at hormones that have other endocrine glands as their target we call them tropic hormones. The four tropic hormones of the anterior pituitary gland are: follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH).
Non-tropic hormones behave in an opposite manner to tropic hormones. They act on target cells rather than on the endocrine glands. Non-tropic hormones are those that act directly on targeted tissues or cells, and not on other endocrine gland to stimulate release of other hormones. 1  Many hormones act in a chain reaction. Tropic hormones usually act in the beginning of the reaction stimulating other endocrine gland to eventually release non-tropic hormones. These are the ones that act in the end of the chain reaction on other cells that are not part of other endocrine gland.
