The Science of Fat Cells Chewing the Fat
How much do you know about your body’s fat storage function, other than the fact that it can make your jeans harder to button? Fat is an integral part of our physiology—we rely on fat to survive. But in a world where one-third of Americans are overweight or obese and fad diets lurk around every corner, it’s important to know why your body needs fat, what kind of fat it needs, and how to keep it in healthy proportions. The Skinny on Fat
• Fat, technically known as adipose tissue, is a loose connective tissue. • Fat is subcutaneous tissue, meaning it is under the skin. • However, fat is found throughout the body, including: Within muscle Inside the liver Atop each kidney What is Fat? Men tend to have more fat in their chests and abdomens. Women tend to have more fat in their hips, waists, and breasts. Did you know? Fat concentrations differ between men and women due to sex hormones.
Humans have two forms of fat: brown fat and white fat. The Two Types of Fat Brown Fat Adults have little to no brown fat. It is found between the shoulders of newborn babies, and is used in the production of heat. White Fat White fat’s main role is to store energy for later use, but it also acts as a form of insulation and cushions bones, joints, and organs.
• When we’re born, we don’t have many white fat cells, which means we can’t retain body heat or properly insulate ourselves. This is where brown fat cells come in. • Brown fat cells are composed of: A nucleus Multiple mitochondria Several small fat droplets • Babies create heat by breaking down the fatty molecules in brown fat cells into fatty acids. • The fatty acids are further broken down by mitochondria, generating heat in the process. Facts About Brown Fat
• Adult humans mainly have white fat cells. • White fat cells are composed of: A tiny nucleus Some cytoplasm (taking up about 15% cell volume) A large droplet of fat (taking up about 85% cell volume) • White fat cells are much larger than brown fat cells. • Think of a white fat cell as a bag holding a drop of fat. When you need energy, your body dips into that bag. Facts About White Fat
• When you work out or don’t have food to get energy from, your body must get its energy from stores of carbohydrates, proteins, and fats. • Fats are broken down into glycerol and fatty acids. These can be broken down for energy or put through the process of gluconeogenesis to form glucose. • Your fat cells shrink as you take away their fatty acids and glycerol. How Does The Body Break Down Fat? The Results of Burning Fat: Heat Water Carbon dioxide
• Remember, fat is an important part of your physiological makeup and helps you to stay healthy. But it is important to keep body fat at healthy levels to prevent weight-related conditions like obesity, diabetes, heart disease, and more. 4 Ways to Keep Fat in Check Wholesome Diet Reduce consumption of processed items in favor of fresh, wholesome ingredients. Aerobic Exercise Get your heart pumping for at least 30 minutes per day 5 days per week. Healthy Lifestyle Get 8 hours of sleep/night Practice stress management (e.g., meditation) Laser Treatment Zerona laser treatments safely reduce trouble spots with zero downtime.
