We need fuel to keep going. (Carbs, Fat, Pro) When we are getting low, low gas light (feel weak, mood altered) So they we fill up (eat) But unlike cars, we have other places to store extra fuel if we need to. And once you put fuel in (eat things) the only way to get rid of it is to burn it up.
Carbohydrates are broken down into building blocks of glucose moleculesProteins are broken down into amino acids (essential and non essential)Fat is broken down into Fatty Acids, and Glycerol Groups. Depending on what cell “doorways” it needs to fit through
Protein’s contribution as a fuel source is relatively small. Because these are so important for building, maintaining body’s systems (nervous, respiratory, cardiovascular system)
Involuntary, don’t even think about doing
As we age, BMR decreasesMen burn more that women: have a higher muscle massStress: Fight or Flight systems, heart races, respiratory increases, ready to goDiet: Energy the GI system uses to digest food. Proteins are hardest for body to digest. As it works hard it takes more energy. Follow carbohydrates, then fats.
Glycogen storage- we have enough to last for about 24 hrs. when they start to fall we start to feel hungry.
You aren’t born with a certain number that you are stuck with for life.Stem Cells are premature cells, baby cells that can turn in to anything. Muscle Cell, Nerve Cell, Skin Cell ect….
When you eat, Insulin Spikes, signals fat cells to suck up fat from blood stream to save it for later. Send antennas out to the edges of the cell. Feeler’s stick out and grab extra fat that are floating around in the blood stream. They also grab any extra glucose floating around in the bloodstream. Because high glucose levels can be toxic to your body’s cells. When you don’t eat- doesn’t necessarily act in reverse. Body thinks your starving. So its going to shut down systems that it considers unnecessary to conserve energy. Decreases your BMR, which makes you burn even less kcal at rest.
Growth Hormone works similarily. Active in infants, kids and adolescents. Signals, we need energy to grow. Take it from storage!
Hormonal Fatty Acid Release: not preferentially, Sit ups aren’t going to burn belly fat any faster than fat from arms. But It will increase the muscle tone in the area, which changes the structure of the abdomen. Excess Post Exercise Oxygen Consumption: Body has to work hard to cool down itself after exercise, this takes calories to do
You want your food to more than just food, you want it to be fuel for you day! This is why you want to avoid big meals and snacking right before bed. Because this food will not be “needed” so it will not be “used” and instead “stored”
SimpleCarbs, refined sugars- easy for our body to break down, so they do not elicit the same Thermic effect. Our bodies don’t have to struggle and use up ATP’s to break them down. So we see a smaller Thermic effect, which decreases the calories burned during digestions
