Obese people are more likely than normal to have hypertension and diabetes, and
their triglyceride and cholesterol levels are more likely to be elevated which makes them susceptible to heart disease and stroke. Obesity may also contribute to the development of gallbladder disease. It complicates the treatment and decrease the chances of survival of patients with kidney disease, stroke and other disorders. Obese women are more prone to cancer of breast, cervix and uterus. Obese men run an increased risk of cancer of the colon, rectum and prostate.
Obesity is the storage of excess fat in the body. A person is considered obese if his or her body weight is 20% or more above a desirable weight.
Obesity can be caused by the disorder of the endocrine glands or diseases of the central nervous system, such as a brain tumor or stroke. Usually the cause of obesity is eating more food than the body can use. But there is exception. Because of genetic factors, some people can remain thin despite they eat more food than their bodies can use.
A person of average size with light physical activity need only about 2400 calories per day. men need about 56 gram of protein per day and women need about 44 gram. 7 oz of ground beef with 10% fat has 50 gram of protein which can contribute 250 calories. A meal with 4 slices of whole-wheat bread, 1 baked potato (148 gram),
1 cup of cooked corn, and 1 apple contain about 780 calories. If we eat 3 meals a day, that will be about 2340 calories. Together with the meat, that is already 2590 calories, more than that we need.
Moreover, the food I show you here are natural food which tend to have less calories than the processed and refined food. On top of that, we sometimes add some condiment which can contribute quite a few calories. One tablespoon of honey has 60 calories. One tablespoon of oyster sauce has about 25 calories. You see. My point here is to show you how easily you can overeat. You should be careful of the calories you are acquiring.
Obese people tend to eat food that has a lot of meat, sugar and fat. Sugar is
100% carbohydrate and yield 385 calories per half cup (100 grams) but contain no other nutrients. Meat provide protein, a necessary nutrient and yield about the same amount of calorie as the carbohydrate. Fat yield 900 calories per 100 grams, more than twice as much as either carbohydrate or protein. Now you can see that fat and
sugar contain a lot of energy. Lean meat do not have many calories but the fact that meat usually carry some fat that make meat a high energy food. Cake, bacon, ice cream, cheese, nuts, candy, fried food, chocolate, corned beef, spareribs, butter, margarines and pie have a lot of sugar and fat. Fried food is a high energy food because oil has a lot of calorie in it. Just one tablespoon of oil contain 120 calories. I don't mean you should not eat these food. But do not eat too much of them.
The excess of carbohydrates and proteins that we eat are turned into fat. But the fact that we eat too much fat is more likely the contributing factor of being obese. Fat cannot be excreted from our body. They are stored and accumulated inside our body. They disappear naturally through metabolism and physical activities.
To avoid getting fat, eat food with less calorie. Food with less calorie are fruit and vegetable or food with more fibre. Refined food are usually have more calorie.
