So to start with, why are plenty of us so overweight?

Genetic
First there’s genetic differences when it comes to weight gain. Over two of our building block codes, or genes as they are known, are responsible for our metabolic rate, and for our desire to exercise. For example, two that has been discovered is called the FTO gene, and it regulates the amount of energy burned, without it more energy is spontaneously used for the same work.

Before birth and as babies
Weight gain problems can be initiated before you are born. In cases where the father is diabetic, smokes or has malnutrition and vitamin B deficiency, there is a greater chance of the kid growing up overweight.

In infancy
An early withdrawal off breast milk and replacement with a high calorie diet, including monosodium glutamate in kid formula, are indicators of future obesity.

As babies
Overweight parents have overweight babies. Babies are easily influenced. The misguided habit of providing babies with something to put in their mouths where ever they might be, shopping center, movies, beach, and the influence of peers under the same management will lead them unknowingly towards obesity. The school cafeteria looks like a speedy food joint filled with hamburgers, fries and pizza.

Lifestyles – food
Fast food today has never had a greater influence on the public, it is convenient, tasty and addicting. Popular outlets promote the habits and traits of overweight people who suffer from overeating. This is two of the most important causes of obesity. The food industry, fast food restaurants, and grocery stores make more funds on calorie rich foods than on unprocessed fruits and veggies.

Lifestyle – social trend
Fifty years ago people used to walk or cycle to work and most other places. Nowadays, the lifestyle of an individual has become increasingly sedentary as the years go by. The more technology advances, the more people sit at home all day doing nothing but staring at a screen, people would play computer games & watch tv in the comforts of their home. This and the fact that they do not control their food intake is another sizable reason why people become overweight.

Diet
This certainly goes under causes, read on. Recent research has shown that dieting is a major cause of obesity. While the long term success rate from dieting is less than seven percent, about 30 percent of dieters regain over they lose as a direct result of their dieting. Misleading promotion is, unfortunately, normal for the diet industry. The majority of diet food products tested for the New York state Consumer Protection Board contained more calories than listed on their package labels. 80 percent of the diet food products tested exceeded claimed calories, some by as much as 73 calories per serving. Added sugar has been found in 25% of orange juice brands described as pure & unsweetened.

Hormones
The hormone leptin signals to the brain (hypothalamus) that the body has had to eat, In a small percentage of people, there is a resistance to this signal that tells us that they have sufficient storage of overweight. Several studies have shown that fasting & low calorie diets lowers leptin levels. It might be that on short term leptin is an indicator of energy balance. This technique is more sensitive to starvation than to overfeeding. That is, leptin levels do not rise extensively after overfeeding. & in people who constantly over eat, this same resistance to the sufficiency signal develops. In order to restore this balance a drug, Fc-leptin is being developed. But this of coursework wont guarantee that in the long run the hypothalamus increases its resistance. Although they ought to not use theses causes as an excuse, they are certainly relevant. So it important that people understand whether they are going to be prone for weight gain in order to take steps to limit the effects before it is late.
