Correction to the comments stated inside the cartoon/ the slide: https://facebook/nutritionhealthmetabolism/photos/a.176128709261516.1073741828.175771665963887/269952276545825/?type=1&theater The hormone insulin does not deprive the body from amino acids as stated in the cartoon. This is a mistake. The peptide hormone regulates the entry of glucose (blood sugar) and branch chained amino acids (BCAA) to muscles. Glucose is used for muscle fueling (excluding the heart, which exclusively uses and fatty acids) while mino acids (the basic units of protein) are the building block of muscles and the rest of our cells. If your muscle is a car, then petrol (gas) will be compared to glucose and fatty acids, while the metals that makes the car like iron and aluminum will be compared to amino acids protein (largely in red muscles which contains about 20% of its mass protein) along with fatty acids, cholesterol, phospholipids and some carbohydrates! Athletes notably body builders may use this knowledge to their advantage. They consume large amounts of carbohydrates and protein such as protein bars in order to fuel (glucose) and build (protein= amino acids) their muscles. It is when someone is often non-active on regular basis and consumes large amounts of refined carbohydrates (and other junk foods) on regular basis that we see negative effects of excess insulin, but why? Because insulin works on two sides when it comes to food processing: • Muscle fueling (glucose) and building (amino acids) • Food storage (glycogen and fat): there is no mechanism to store protein by the way. Muscle building is not protein storage! It is up to us to decide which side insulin will go. Even type I diabetics whose pancreas do not make insulin and must take insulin injection for life in order to live can still work out, build muscles and live as healthy as anyone else. I had an encounter and friendship with some type I diabetics including a 23 year-old type I diabetic who is an athlete (body builder and mountain biker). What happens when we eat too much and do not burn our foods, we store them. Even excess protein may converts to fat and be stored as fat not protein. This is very rare though. What causes sleepiness? 1-When we consume too much of anything, our stomach becomes full and the blood will be diverged from the brain. This explains sleepiness and sluggishness. 2-This is not the end of the story yet! When we consume high carbohydrates meal with some protein, the hormone insulin still can send BCAA to their metabolic sites like muscles and liver (for further metabolic actions). The essential amino acid tryptophan (TR) is not regulated by insulin. TR level rises in the plasma and the cerebral-spinal fluid and enters the brain without insulin permission (and so does glucose entry to the brain). Excess TR in the brain converts to the neurotransmitter serotonin and the pineal sleep hormone melatonin. This too has been studies as a reason why individuals go into sleep after large high-carbohydrates and protein meals (such Thanksgiving Dinners).
