Inability to Lose Weight

Losing weight is priority for many; however, it requires a safe and healthy diet and exercise plan to lose weight and keep it off for good. Some may try everything from cutting calorie intake to increasing the intensity of their workout plan, yet, still have trouble keeping those unwanted pounds off. There are many physical reasons that people cannot lose and keep off weight.

Hypothyroidism

• Hypothyroidism, or an underactive thyroid gland, is a condition in which the gland does not produce enough hormones and upsets the normal balance of chemical reactions in the body. Affecting mostly women above the age of 50, this can lead to numerous problems such as obesity, joint pain, infertility, and heart disease. The thyroid produces thyroxin, a hormone responsible for bowel movements, appetite, and metabolism. When this is underactive, it can lead to obesity in an individual.

Adaptation

• The complexity of the human body allows for it to adapt to its surroundings, and it allows it to adapt to how one is treating his or her own body. Once a body has grown accustomed to a change in calorie intake or an increase in exercise or intensity, one may notice that the weight loss has halted. Changing the diet, adding more weight, exercising longer, or trying new exercises may be the spark to continue losing weight. according to Diet.lovetoknow.com.

Unrealistic Expectations

• Having unrealistic expectations for weight loss is a main reason that people give up on a plan too easily and too quickly. Reducing calorie intake by 300 to 500 calories per day, along with an exercise program, can show a weight loss of one to two pounds per week, according to Netdoctor.co.uk. An expectation of anything larger than this could cause someone to go to drastic measures to lose weight, and this could lead to an unhealthy and unsafe lifestyle.

Drastic Diet

• A drastic diet may cause someone to lose weight quickly. However, it is unsafe and an unreliable way to lose a desired amount of unwanted fat. A small decrease in calories is enough to lose weight. A decrease in calories below 1,500 calories per day, also known as a "crash diet," usually ends in a person becoming much weaker and giving up on the plan. Even if one does lose weight quickly as the result of crash dieting, it is typically hard to keep the weight off due to high rate of quitting such a drastic diet.

Healthy Loss

• The healthiest way to lose weight is not in bursts of intense exercise or drastic diet, but in a constant and slow change in terms of reduced calorie in-take and working out. Someone who has not worked out in years and desires to lose weight should not go out and run a couple of miles, for this may lead to injury and may set back fitness levels even further. Diets that restrict certain foods, decrease the amount of calories consumed per day, and incorporate a safe exercise program are enough to lose weight in a healthy way and keep it off for good.
