As discussed, many methods guardian can be used to assess percent body fat. Regardless of which method is chosen, the individual should use the same method for subsequent evaluations. It is also important to remember that changes in body composition come slowly and require effort.
Increasing Body Fat (If Too Lean)
It is evident from the changes taking place during puberty and menopause, in women with polycystic ovary syndrome and in transgendered individuals that sex hormones have multiple effects of adipose tissue. Human adipocytes, as well as preadipocytes, express sex steroid receptors [154,155]. Androgens have also been shown to increase glucose uptake [159].

White fat is the type of fat that most people immediately think of. The mechanism involves cortisol’s effects on neurotransmitter systems, particularly serotonin and dopamine. You may experience low motivation, loss of interest in activities you once enjoyed, and persistent sadness that feels different from situational unhappiness.
Why Cortisol Symptoms Vary Between Women
This type of fat is required for various bodily processes, including hormone production, temperature regulation, and absorption of fat-soluble vitamins (A, D, E, and K). Without adequate essential fat, normal bodily functions may be compromised. Knowing your body fat composition is important in coming up with good fitness targets. So, if you know most of your fat is stored for later use, you may concentrate on developing your endurance and controlling the types of food you eat.
Tips for Managing Essential Body Fat Levels:
What many people don’t realize is that there are several types of body fat – some that are good and others that aren’t so good. It’s believed that certain hormones and enzymes released when you’re stressed, cold, or when you exercise can help convert white fat into beige fat. These fat cells function somewhere between brown and white fat cells. Similarly to brown fat, beige cells can help burn fat rather than store it. High cortisol interferes with the conversion of inactive T4 thyroid hormone to active T3, which can create symptoms of hypothyroidism even when TSH levels appear normal. Cortisol also reduces thyroid hormone receptor sensitivity, meaning tissues respond less effectively to available thyroid hormone.
Balancing Essential Fat for Optimal Health
Testing becomes essential when symptoms persist despite lifestyle modifications or when multiple symptoms cluster together. A single symptom like fatigue or weight gain doesn’t necessarily indicate high cortisol, but the combination of abdominal weight gain, mood changes, skin thinning, and muscle weakness warrants investigation. Fat accumulates around the midsection, creating an apple-shaped body composition even in women who were previously pear-shaped. You may also notice a fatty deposit between the shoulder blades, sometimes called a buffalo hump, and fullness in the face that creates a rounded appearance. During perimenopause and menopause, declining estrogen levels reduce the body’s ability to buffer cortisol’s effects.
Non-Essential Body Fat: Understanding the Difference
These symptoms result from cortisol’s effects on the hippocampus, the brain region responsible for memory formation. You may feel on edge without a clear reason, experience racing thoughts, or have difficulty relaxing even in calm environments. This isn’t psychological weakness; it’s your nervous system responding to sustained cortisol elevation. Women with subclinical hypothyroidism may experience more pronounced symptoms because the thyroid and adrenal systems regulate each other. When one is compromised, the other compensates, often unsuccessfully. This layer remains relatively consistent in the body and serves more of a protective role than a fuel source.

When I was a medical student beginning to dissect a cadaver in the anatomy laboratory, I was amazed by how much fat there was. The bones, muscles, blood vessels, nerves, and organs were all there — just no fat. It was as if the anatomy book artists had performed liposuction before starting to draw. Beige fat – Beige fat is not entirely understood by medical science, but it’s thought to be a combination of white and brown fat. Women naturally carry more essential fat due to reproductive and hormonal needs, which support fertility, pregnancy, and overall hormonal balance.
Which Provides Long-Term Energy Storage: Fat or Glycogen?
- For example, healthy women need around 10 to 13 percent of their total body weight to be comprised of essential fats.
- On the other hand, the uptake of meal-derived fatty acids by VAT in men exceeds that in women, whether it is calculated as % of total meal disposal or as absolute values (μmol/min) [111].
- Other disadvantages are that it is not portable, it is time consuming, and fairly complex.
- With insulin no longer blocking the process, enzymes break through the perilipin barrier and begin splitting triglycerides into free fatty acids.
- While there’s limited research on potential negative effects, excessive conversion from white to beige may not always be beneficial if not paired with healthy lifestyle choices.
- Storage fat, by contrast, acts as an energy reserve that builds up when you eat more than your body needs and gets used up when you burn more than you consume.
On the other hand, in situations where metabolic fuels are not sufficient to meet energy needs, a lipolytic cascade is initiated and results in the breakdown of triglycerides into free fatty acids and glycerol. Thus, adipose tissue is expanded and remodeled in response to alterations in the energy status/stress (64). Too much visceral fat can lead to several health issues such as dementia, certain cancers, Alzheimer’s, Type 2 diabetes, and even strokes.
Can Your Body Suffer As A Result Of Having Low Essential Fat?
It helps regulate hunger by producing certain hormones and has receptors for insulin and cortisol. White fat also serves as the biggest energy backup in our bodies. It can be found all over the body, including arms, shoulders, stomach, and legs. A certain amount of subcutaneous fat is normal and healthy, but too much can lead to imbalanced hormone levels and sensitivity.
