Excerpts from the link (see enclosure):
Lack of Energy Balance
A lack of energy balance most often causes overweight and obesity. Energy balance means that your energy IN equals your energy OUT.
Energy IN is the amount of energy or calories you get from food and drinks. Energy OUT is the amount of energy your body uses for things like breathing, digesting, and being physically active.
To maintain a healthy weight, your energy IN and OUT don't have to balance exactly every day. It's the balance over time that helps you maintain a healthy weight.
The same amount of energy IN and energy OUT over time = weight stays the same
More energy IN than energy OUT over time = weight gain
More energy OUT than energy IN over time = weight loss
Overweight and obesity happen over time when you take in more calories than you use.
Other Causes
- An Inactive Lifestyle
- Environment (Lack of neighborhood sidewalks and safe places for recreation, work scheduled, oversized food portions, food advertizing, etc)
- Genes and Family History
- Health Conditions (Some hormone problems may cause overweight and obesity, such as underactive thyroid (hypothyroidism), Cushing's syndrome, and polycystic ovarian syndrome (PCOS).)
- Medicines (Certain medicines may cause you to gain weight. These medicines include some corticosteroids, antidepressants, and seizure medicines.)
Emotional Factors (Some people eat more than usual when they're bored, angry, or stressed. Over time, overeating will lead to weight gain and may cause overweight or obesity.)
- Smoking (Some people gain weight when they stop smoking. One reason is that food often tastes and smells better after quitting smoking.
Another reason is because nicotine raises the rate at which your body burns calories, so you burn fewer calories when you stop smoking.)
- Age (As you get older, you tend to lose muscle, especially if you're less active. Muscle loss can slow down the rate at which your body burns calories. If you don't reduce your calorie intake as you get older, you may gain weight. Midlife weight gain in women is mainly due to aging and lifestyle, but menopause also plays a role. Many women gain about 5 pounds during menopause and have more fat around the waist than they did before.)
- Pregnancy (During pregnancy, women gain weight to support their babies’ growth and development. After giving birth, some women find it hard to lose the weight. This may lead to overweight or obesity, especially after a few pregnancies.)
- Lack of Sleep (Research shows that lack of sleep increases the risk of obesity.)

People may make decisions based on their environment or community. For example, a person may choose not to walk to the store or to work because of a lack of sidewalks. Communities, homes, and workplaces can all influence people's health decisions. Because of this influence, it is important to create environments in these locations that make it easier to engage in physical activity and to eat a healthy diet.
There may be places in your area that support physical activities from parks, trails, and sidewalks to recreation and fitness centers. Even malls provide opportunities for fitness walking. Understanding environmental opportunities and barriers that we face in our pursuit for a healthy lifestyle may provide some of the knowledge necessary to promote healthy living. This information may also provide ideas for advocacy and civic participation.
cience shows that genetics plays a role in obesity. Genes can directly cause obesity in specific disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome.
However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight. In some cases multiple genes may increase one's susceptibility for obesity and require outside factors; such as abundant food supply or little physical activity.

Depending on lot of calorie rich food, keeping body at rest for most of the time, avoiding exercises or hard work added with hereditary links are few of the major causes behind obesity.
My personal experience is that: the lack of physical exercise leads to overweight and obesity.
Dear Abedallah,
I partially agree with your statement. Your analysis is the normal reaction to obesity. But it´s a little bit to simple. You know, there are different features influencing the metabolism. Just remember the thyroid hormons or the status of intestinal bacteria.
My personal solution is: eat the right food, not to much of the treats, do a lot of sports.
I totally agree with you dear @Hanno, "eat the right food, not too much of treats, do a lot of sports."
Eminent friends - "Eat the right food" is a good advice. We also need to drink a minimum of 3 litres of water per day. Many of my friends prefer to drink soda / cola drinks instead of water. Also, "eat the right food at the right time" is a good advice. It is always preferable to avoid a heavy dinner at night. A light food for dinner is always ideal. Green tea without sugar is very nice. I am looking forward to my Tunisia trip in March to take green tea with mint leaves along with friends from Tunisia and Algeria. Fasting once in a while also helps regulating the stomach functioning. Also, midnight snacks may be kindly avoided. (I posted medical problems with over-night snacks in a separate query).
The prevalence of overweight and obesity in Australia has been increasing steadily over the past 30 years. According to the National Preventative Health Taskforce Australia, it has been estimated that if current trends continue unabated over the next 20 years, nearly three-quarters of the Australian population will be overweight or obese in 2025. The results give an indication of the potential deaths and PYLL to be saved if effective action is taken to reduce overweight/obesity. The results show that strategies targeting a reduction in the prevalence of overweight/obesity at a whole of population level will be most effective. If only children are targeted progress will be very slow.

I would like you to refer this RG discussion..https://www.researchgate.net/post/What_is_the_link_between_child_obesity_and_daily_activities#view=53967e09d039b19b048b45dd
There are many motives for obesity. More than one motive can be found in a single person. Obesity is not exclusively a creation of modern society or of modern diet as many state. There are examples of obesity which are as old as 45,000.
See this article for some examples:
www.hormones.gr/pdf/241-244.pdf
Important factors for obesity are hormone levels and genetics. I can't understand that a energy deficit can contribute to ideal weight control. No system can function properly if its goal is to cause a energy deficit. What makes our body lose fat are hormones and enzymes, not heat or any combustion process.
We have not evolved from steam engines to depend on beat to produce work. Our bodies run on chemical energy from the macronutrients (carbohydrates, fat, and protein), which are processed in the mitochondria. Respiration and combustion is not the same process.
Many suggestions were given in this discussion thread..
Hope people got benefitted by the suggestions given..
A little or long walk every day.. some aerobic activity, avoiding junk foods, eating organic food, good diet, exercise, biking or jogging, and good sleep are keys to keep good shape.. Kindly avoid junk food at late night while watching movies or sports!
Best wishes, Sundar
