If you are told that you should not consume any more than 61 % of your calories from protein, how many grams of protein should you eat in a day?

Describe in detail the role that the hypothalamus plays in determining whether or not you feel like eating.

When the nutrient level of the blood begin to rise, the satiety center is activated and our desire to continue to eat declines. Name the four types of external forces that influence our eating habits and patterns and give an example of how you experience each in your life. Ans- 1.
