Why don’t diets seem to work?

Why don’t diets seem to work? Going on" a diet is not the answer to losing weight. This is because the weight is soon regained after you "go off" your diet. If diets really worked, there wouldn't be so many of them! Instead, your usual eating and exercising patterns need to be changed so that your weight stays right for you


The incidence of childhood obesity is rapidly rising throughout the world. The obesity epidemic is especially evident in industrialized nations where many people live sedentary lives and eat more convenience foods, which are typically high in calories and low in nutritional value. In just two decades, the prevalence of overweight doubled for U.S. children ages 6 to 11 — and tripled for American teenagers. The annual National Health and Nutrition Examination Survey by the Centers for Disease Control and Prevention found that about one-third of U.S. children are overweight or at risk of becoming overweight. In total, about 25 million U.S. children and adolescents are overweight or nearly overweight


Obesity does not just happen overnight – it develops gradually from poor diet and lifestyle choices and, to some extent, from your genes.


Lifestyle choices are an important factor in influencing your weight. Eating more calories than you need may be down to poor food choices – for example, eating high fat, processed, or fast food – rather than filling up on fruit, vegetables and unrefined carbohydrates, such as wholemeal bread and brown rice. Alcohol also contains a lot of calories, and heavy drinkers are often overweight.

Bad eating habits also tend to run in families – rather than inheriting a slow metabolism, the habits learned from your parents can be an important factor. Childhood obesity is a strong indicator of weight-related health problems in later life, showing that learned unhealthy lifestyle choices continue into adulthood. eatless

Lack of physical activity

Lack of physical activity is another important factor that is related to obesity. Many of us have jobs that involve sitting at a desk for most of the day, and we rely heavily on our cars to get around. When it is time to relax, we tend to watch TV, or play computer games, and rarely take any regular exercise. If we are not active enough to use up the energy provided by food, the extra calories are stored as fat instead.

Some people tend to stay the same weight for years without much effort, whereas others find they put on weight quickly if they are not careful. This could be due in part to your genes – scientists have discovered certain genes that make you feel hungrier, or make it take longer for you to feel full.


In less than one out of every 100 cases, there is a medical reason for obesity. Conditions such as Cushing’s syndrome (over-production of steroid hormones in the body) and an under-active thyroid gland are rare causes of weight gain.

Certain medicines, including some steroids and antidepressants, can contribute to weight gain. Also, taking the contraceptive pill and quitting smoking may increase your appetite.
