Why do we get fat - Why do we gain weight as we get older? HD

In this video I discuss why do we get fat, and why do we gain weight as we get older. Our metabolism slows, we become less active and lead a sedentary lifestyle, and our relationship with food changes. Transcript (partial) Generally, At 6 months an infant’s birth weight has doubled, and tripled by their 1st birthday. As an infant gets older, growth continues. In fact, Growth in height usually stops at age about age 16 for females and around 22 for males. Bones, organs and other body tissues are getting larger, and lean body muscle is developed. All of this growth requires energy, and where does the body get energy from? Food, of course. So, when we are young, with all of the growth taking place, most, if not all of the food we eat, is being used as energy to fuel this growth. And that means that not much, if any, fat storage is taking place. Once this growth period stops, we are at our physical peak, and the body enters a simple maintenance stage. So, now that high energy requirement, starts to decline, and continues to decline as we get older, that is, unless WE OURSELVES, do something about it. Next lets shift gears and look at the typical activity level of a person over the course of their life. As an infant and small child we start to crawl and eventually walk. Kids are typically investigating all the new things they are exposed to, running around and playing all the time. They are very active. As kids get older they typically continue to be very active, going to the playground, playing around with their friends outside, getting into sports, and riding their bikes everywhere. They are still running around and being active all the time. Then, adolescence and teen years hit, and their activity level may increase a bit, because they are still hanging out with friends and usually doing physical activities or at least moving around a lot. Next up is college years and mid twenties. Here, the activity level may stay the same or decline slightly, but most 20-somethings are still relatively active and many have more labor or physical type jobs. Then the late twenties and 30’s hit, and here is usually where we see a significant change in activity level. Many people have settled into a desk job, where they are sitting most of the day. Going out with friends usually means going to a bar, restaurant or grilling out at someone’s house, with very little to no physical movement at all. Hopefully you see the pattern here. Now let’s look at the 3rd part of our puzzle, I am going to call it computer programming. The brain is absorbing and learning, I like to think of it as computer code is be written into it. It is being programmed with educational information, learning to dealing with people, understanding right and wrong, and it is also developing relationships. Relationships with family, friends, teachers, pets, and it is also being programmed to develop a relationship with food. As a child, we are often told, make sure
