What To Do About Borderline Thyroid Levels

However, some studies have found that only 5 percent of people have a TSH above 2.5 (though others say it's more like 15 percent). That is to say, being above 2.5 is statistically abnormal. And abnormalities are, by and large, how medicine decides what a disease is.

How to Increase Your Brown Fat

There are two colors of fat, brown fat and white fat. The fat we are most familiar with is white fat, which comprises most of the fat in the body. Most of the fat in our body is white fat. White fat is a storage depot for excess calories and provides insulation. White fat produces inflammation, an unhealthy situation for the body. Brown fat is a healthy type of metabolically active fat. Brown fat is named as such because it contains a lot of energy-generating mitochondria which gives rise to the color. Brown fat is considered “good” fat because it burns calories and generates body heat. There are different types of fat. Fat is actually a series of different types of tissues with different functions. The location of fat matters and that fat in the belly is the unhealthiest type of fat that leads to many of the problems we associate with obesity including insulin and leptin resistance. But location is not the only factor that distinguishes different types of fat.

Not Sleeping? Circadian Rhythms are Critical for Long Term Weight Management

Your circadian rhythm is the 24-hour clock that drives wakefulness and sleep. Disruptions to this biological clock have profound effects on our bodies and our hormones. New research has identified genes for the biological clock, known as clock genes, which may be the basis for metabolic diseases like obesity, diabetes and insulin resistance.

Adrenals Shot? Probably Not.

Whatever you want to call it—adrenal fatigue, exhaustion, or burnout—it is not a real hormonal condition. Adrenal fatigue is a fake diagnosis that has no scientific basis. If you have been told you have adrenal fatigue, get a second opinion from a board-certified endocrinologist.

Hunger Hormones

"In the past 20 years, we've learned a lot about hunger and satiety hormones," says Scott Isaacs, MD, a board-certified endocrinologist in Atlanta and author of Beat Overeating Now! "The first one was leptin, which was discovered in 1994." Since then, many other hormones that impact hunger, appetite, cravings, and weight have been discovered. "Leptin is a hormone that's produced by fat cells, and it works to suppress appetite in the brain," Isaacs explains. "We used to think a fat cell was an inert storage depot for excess fat, insulating the body. But now we know that fat is an endocrine organ, that is, a gland that produces hormones. Leptin is just one of the hormones produced by fat cells." The amount of leptin circulating in a person is proportional to the amount of body fat and indicates how much energy stores a person has.
