The balance between calorie intake and energy expenditure determines a person’s weight. If a person eats more calories than he or she burns (metabolizes), the person gains weight (the body will store the excess energy as fat). If a person eats fewer calories than he or she metabolizes, he or she will lose weight. Therefore, the most common causes of obesity are overeating and physical inactivity.

  • A person is more likely to develop obesity if one or both parents are obese. Genetics also affect hormones involved in fat regulation. For example, one genetic cause of obesity is leptin deficiency. Leptin is a hormone produced in fat cells and in the placenta. Leptin controls weight by signaling the brain to eat less when body fat stores are too high. If, for some reason, the body cannot produce enough leptin or leptin cannot signal the brain to eat less, this control is lost, and obesity occurs. The role of leptin replacement as a treatment for obesity is under exploration.
  • Overeating leads to weight gain, especially if the diet is high in fat. Foods high in fat or sugar (for example, fast food, fried food, and sweets) have high energy density (foods that have a lot of calories in a small amount of food). Epidemiologic studies have shown that diets high in fat contribute to weight gain. Drinking too much alcohol – alcohol contains a lot of calories, and people who drink heavily are often overweight.
  • Lack of physical activity. Lack of physical activity is another important factor related to obesity. Many people have jobs that involve sitting at a desk for most of the day. They also rely on their cars, rather than walking or cycling. For relaxation, many people tend to watch TV, browse the internet or play computer games, and rarely take regular exercise. If you’re not active enough, you don’t use the energy provided by the food you eat, and the extra energy you consume is stored by the body as fat.
  • Medications associated with weight gain include certain antidepressants (medications used in treating depression), anticonvulsants (medications used in controlling seizures such as carbamazepine [Tegretol, Tegretol XR, Equetro, Carbatrol] and valproate [Depacon, Depakene]), some diabetes medications (medications used in lowering blood sugar such as insulin, sulfonylureas, and thiazolidinediones), certain hormones such as oral contraceptives, and most corticosteroids such as prednisone. Some high blood pressure medications and antihistamines cause weight gain. The reason for the weight gain with the medications differs for each medication. Diseases such as hypothyroidism, insulin resistance, polycystic ovary syndrome, and Cushing’s syndrome are also contributors to obesity. Some diseases, such as Prader-Willi syndrome, can lead to obesity.
  • Social issues. There is a link between social issues and obesity. Lack of money to purchase healthy foods or lack of safe places to walk or exercise can increase the risk of obesity.

Recent studies have shown that when acupuncture is combined with traditional methods of weight loss, patients lose more weight. In these cases, one to three acupuncture weight loss sessions can be safe and effective in helping people achieve reasonable weight loss goals.

Acupuncture involves the insertion of very fine, sterile needles at specific body points or “energy pathways.” The inserted needles act to stimulate the release of endorphins, the body’s natural “feel good” hormones. This can create a calming, relaxing effect, which counteracts the need for excessive eating brought about by increased stress, frustration or anxiety.

The effect of acupuncture on a client’s emotions also plays an important role in aiding weight loss. Acupuncture affects the neuroendocrine system by blocking harmful neurochemicals to restore the natural balance of hormones and neurotransmitter levels. The resulting release of endorphins helps to reduce stress, which in turn helps to prevent the urge to overeat.
