Goals of treatment of obesity

a. Ideally, treatment would "cure" overweight and obesity b. In reality, this ideal is seldom achieved

how is stress a vicious cycle

a. Impaired immunity leads to increased risk of disease, disease compromises nutritional status, and compromised nutritional status further impairs immunity. b. Recovery requires that this cycle be broken. We can't stop cycle until we identify what the problem is!!!!!!

food-drug interactions

a. Knowledge of all types of potential interactions between food, nutrients, and drugs helps make patient care more comprehensive.

what happens during starvation

a. Liver glycogen is used first to maintain normal blood glucose levels and to provide energy for brain and blood cells- usually depleted in 24hrs b. Lipid (triglyceride) stores begins and as the amount of liver glycogen decreases free fatty acids are mobilized for energy- use fat for energy c. After about 24 hours without intake, the prime source of glucose is from gluconeogenesis. d. During early starvation, the brain uses glucose from muscle protein. (By day 2 or 3 of starvation, about 75 g of muscle protein is catabolized each day!! Not good. Less protein, less healing the body) e. Ketone bodies produced if starvation prolonged.... They are from fatty acids. Will cause bodies demand for glucose to decrease! Will see a lot of neurologic deficits to increase
