Most fat is stored underneath the skin and is known as subcutaneous fat. This is the fat that is visible and that you can feel. The rest of the fat in the body is stored around your internal organs, including your heart, liver and intestines. This is visceral fat.
There are many ways to measure body composition, including expensive body scans, but in most cases, simple measurements are sufficient. Measuring waist-to-hip ratio is a quick way to estimate visceral abdominal fat vs subcutaneous lower body fat.
It responds to insulin by converting excess blood sugar to lipids and storing them away for future use. Sex hormones partly determine where fat is deposited in your body.
Subcutaneous versus visceral fat
She explains that generally people who are healthy store most of their fat (around 80% of it) in the subcutaneous regions because that's where it's most useful to your body.
Fat is stored in the body in different compartments. The two main compartments are subcutaneous (under the skin) and visceral or abdominal (around the internal organs). You may also hear the term ectopic fat, which is when fat “overflows” into other tissues, such as the liver, pancreas and muscles.
Belly fat, especially stubborn lower belly fat, is one of the most persistent types of fat to lose. Many people struggle with it for months or even years, despite trying different diets, exercises, and weight-loss techniques. Understanding why belly fat is the hardest to lose is essential to overcoming this challenge.
If you're asking yourself, “Why am I gaining weight when I barely eat,” several factors may be at play. Your body may be holding onto fat stores if your eating habits are inconsistent or restricted. Or, your weight gain may be the effect of a sedentary lifestyle, medical condition, or long-term stress.
Too many starchy carbohydrates and bad fats are a recipe for that midsection to expand. Instead, get plenty of veggies, choose lean proteins, and stay away from fats from red meats. Choose healthier fats in things like fish, nuts, and avocados. Even a moderate cutback on carbs (grains, pasta, sugars) can help, too.
You also can't control where your body stores fat. "Factors like body type, age, hormones, and genetic predisposition all determine where excess fat ends up," says Dr. Apovian.
Fat burning typically begins after approximately 12 hours of fasting and escalates between 16 and 24 hours of fasting.
Weight loss resistance is a complex issue that is influenced by various factors, including hormonal imbalances, chronic stress, poor sleep quality, medications, poor gut health, thyroid disorders, sex hormone fluctuations, and blood sugar imbalance with insulin or leptin resistance.
It's caused when extra calories are stored in the body as fat. If you consume high amounts of energy, particularly found in high fat and high sugar foods, and do not use all of the energy through physical activity, much of the extra energy will be stored in the body as fat.
Equally unfortunate is the fact that cortisol belly doesn't have a specific appearance, despite what countless infographics on the internet will tell you. Cortisol belly simply looks like abdominal fat, and there is no way to identify it by appearance.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.
The Science of Fat Loss
Think of it like a balloon losing air—it deflates, but doesn't disappear immediately. Over time, your body adjusts, but the jiggly feeling can be a temporary step along the way.
Activities like running, cycling, and high-intensity interval training (HIIT) burn more calories and fat throughout the body, including the upper belly, lower belly, and obliques. So, while ab exercises can help define your core, it's a holistic approach that will help you lose the fat covering those muscles.
What does “skinny fat” look like? Phenotypically, they look lean and healthy, but when we check them out they have high levels of body fat and inflammation. This ectomorph body build has hidden high levels of body fat. They appear thin and flabby.
