In today’s society people are becoming more aware of obesity. We are more in tune with our bodies and how they function. We believe people are obese due to over eating, however this is not always the case. In order to reduce obesity we must first know what causes it. Obesity can be caused by may contributing factors like,

  • Eating more than your body can use
  • Alcohol
  • Not enough exercise
  • Hormones

Hormones actually have an affect on how much we eat as well as our energy levels to exercise. There are several hormones that can cause an abnormal metabolism and the accumulation of body fat. The hormones LeptinInsulinEstrogenTestosteroneGrowth Hormones, and Cortisol all influence our appetite, metabolism, and distribution of body fat.


Vital in the regulation of appetite. A protein made in the fat cells, flows through the bloodstream and goes to the brain. Informing your brain that your fat cells has enough energy stored to go about a normal active day or if you need to go into starvation mode. A normal level of leptin tells the body when to stop eating, while a lower level causes the body to store fat. Leptin resistance, When brain does not know we have enough fat stored and therefore thinks that we’re starving, is believed to be a leading driver of obesity.


Secreted by a group of cells in the pancreas it moves the glucose required as a source of energy from our bloodstream into the individual cells. Spikes in insulin can block the leptin signal in the brain causing hunger which causes your body to store fat. Refined carbs and sugars are the worst offender that raises these endorphins in the brain. Studies show that eating less carbs can drastically reduced insulin and automatically cause weight loss. Anything below 5 grams of sugar does not spike your sugar. Things high in carbs and sugar: Ex: Potatoes, pasta, bread, candy, soda, and some juices can spike sugar.


Considered to be a Female Hormone can be found in both men and women causes fat to store in the mid section and the hip areas. It increases the number of alpha-adrenergic receptors in the lower portion of the body slowing the release of fat. It also causes fat to store in the subcutaneous areas(under skin an in arms and legs). A high level of estrogen causes weight gain an can make your body feel soft and spongy.


Considered to be the Male hormone can be found in both men and women secreted by the testesadrenal gland, and ovaries. Testosterone determines body composition and fat accumulation, low levels are strongly correlated with obesity and the metabolic syndrome in men. These low levels create high body mass index (BMI), along with elevated ratios of body fat to lean mass. Testosterone plays a vital role in how our bodies balance glucose, insulin, and fat metabolism. There are ways to reverse the low levels of testosterone by doing vigorous resistance exercise, weightlifting movements that hit multiple muscle groups, limit rest between sets, and keep cardio to a minimum. This approach stimulates your body’s production of growth hormone, which helps you build more muscle faster.

Growth Hormone

Also know a the stress hormone, produced by the pituitary gland helps to regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function. It raises glucose and free fatty acids.



Also known as a stress hormone or a steroid hormone produced by the zona fasciculata of theadrenal cortex. It’s primary function is to increase blood sugar through gluconeogenesis; suppress theimmune system; and aid in fat, protein and carbohydrate metabolism. All this affects your body ability to convert sugars to energy. Excess cortisol also inhibits your body from burning fat for energy. Without an optimal ability to burn fat, sustainable weight loss becomes exceedingly difficult. Way s to manage your cortisol:

  • Low Caffeine intake
  • Exercise efficiently
  • Relaxation
  • Sleep

In essence People who are obese have hormone levels that encourage the accumulation of body fat which is a risk factor for disease.
