>That excess fructose is broken down by the liver and transformed into fat globules (triglycerides) I believe this is not "that" accurate. Generally the presence of excess carbohydrates cause the body to prioritize sucrose/fructose/glucose to glycogen conversion and storage & usage. Dietary Lipids that are ingested are stored rather than used for energy. While, De novo lipogenesis (turning carbs to lipids) does occur…
> Excess sugars are generally used up by kids who are growing. However, once people reach adulthood, the growth rate slows so significantly that the excess caloric intake forces all the lipids ingested to be stored. Huh? You mention that the SUGARS the kids are eating are used for growth. But then say it's the LIPIDS (dietary fats) that are stored in adults? What about the sugar...? I've always been skinny, and even…
Point was that kids generally have a “higher metabolism” because they are in a growth stage. (Hence using up the sugars) The adolescent body is generating tons of human growth hormone and testosterone to build muscle, bone, cartilage, etc and that activity is calorically intensive.
When people get older, that activity subsides so much that eating at the same rates as an adult leads to weight gain. Plus, kids are generally more active having to walk from class to class while most adults (us office workers) are sitting all day.
The body also likes to stay at a homeostasis of sorts for weight. Listening to you body and only eating when you’re hungry and maintaing weight is a wonderful genetic trait most people have.
Body builders who have wanted to get larger but could not would actually force fed themselves the calories to the point of being mildly sick.
People usually have mentioned post-workout hunger the say of or the next day. Thats where the body lifting weights craves a lot of calories for growing.
