We all know someone who can eat all the sweet treats, and whatever else they want and still not gain weight. At the other extreme are people who seem to gain weight no matter how little they eat. Why? What allows one person to remain thin without effort but demands that another struggle to avoid gaining weight or regaining the pounds he or she has lost previously?
On a very simple level, your weight depends on the number of calories you consume, how many of those calories you store, and how many you burn up. But each of these factors is influenced by a combination of genes and environment. Both can affect your physiology (such as how fast you burn calories) as well as your behavior (the types of foods you choose to eat, for instance). The interplay between all these factors begins at the moment of your conception and continues throughout your life.
The simple math
Calorie burnt is calorie lost rest are stored expanding your calorie basket.
So the fat cells are becoming bigger and happier when they are energized pm he other spectrum they become sad and shrieveled when stripped of energy.
The bottom, line is you dont want your fat cells to be happy.
You want you fat cells to be sad, very sad.
Many studies have concluded that, more than 400 different genes have been implicated in the development of overweight or obesity, although only a handful appear to be major players. Genes contribute to obesity in many ways, by affecting appetite, satiety (the sense of fullness), metabolism, food cravings, body-fat distribution, and the tendency to use eating as a way to cope with stress.
The strength of the genetic influence on weight disorders varies quite a bit from person to person. Research suggests that for some people, genes account for just 25% of the predisposition to be overweight, while for others the genetic influence is as high as 70% to 80%. Having a rough idea of how large a role genes play in your weight may be helpful in terms of treating your weight problems.
Genes are probably a significant contributor to your obesity if you have most or all of the following characteristics:
- You have been overweight for much of your life.
- One or both of your parents or several other blood relatives are significantly overweight. If both of your parents have obesity, your likelihood of developing obesity is as high as 80%.
- You can’t lose weight even when you increase your physical activity and stick to a low-calorie diet for many months.
Genes are probably a lower contributor for you if you have most or all of the following characteristics:
- You are strongly influenced by the availability of food.
- You are moderately overweight, but you can lose weight when you follow a reasonable diet and exercise program.
- You regain lost weight during the holiday season, after changing your eating or exercise habits, or at times when you experience psychological or social problems.
People with a strong genetic predisposition to obesity may not be able to lose weight with the usual forms of diet and exercise therapy. Even if they lose weight, they are less likely to maintain the weight loss. For people with a very strong genetic predisposition, sheer willpower is ineffective in counteracting their tendency to be overweight. Typically, these people can maintain weight loss only under a doctor’s guidance. They are also the most likely to require weight-loss drugs or surgery.
The prevalence of obesity among adults in the United States has been rising since the 1970s (see Figure 1). Genes alone cannot possibly explain such a rapid rise. Although the genetic predisposition to be overweight varies widely from person to person, the rise in body mass index appears to be nearly universal, cutting across all demographic groups. These findings underscore the importance of changes in our environment that contribute to the epidemic of overweight and obesity.
After birth, babies who are breast-fed for more than three months are less likely to have obesity as adolescents compared with infants who are breast-fed for less than three months.
Technology and fastfoods: Kids who drink sugary sodas and eat high-calorie, processed foods develop a taste for these products and continue eating them as adults, which tends to promote weight gain. Likewise, kids who watch television and play video games instead of being active may be programming themselves for a sedentary future.
Many features of modern life promote weight gain. In short, today’s “obesogenic” environment encourages us to eat more and exercise less. And there’s growing evidence that broader aspects of the way we live — such as how much we sleep, our stress levels, and other psychological factors — can affect weight as well.
Fat isn’t necessarily the problem; in fact, research shows that the fat content of our diet has actually gone down since the early 1980s. But many low-fat foods are very high in calories because they contain large amounts of sugar to improve their taste and palatability. In fact, many low-fat foods are actually higher in calories than foods that are not low fat.
The exercise crunch
Our daily lives don’t offer many opportunities for activity. Children don’t exercise as much in school, often because of cutbacks in physical education classes. Many people drive to work and spend much of the day sitting at a computer terminal. Because we work long hours, we have trouble finding the time to go to the gym, play a sport, or exercise in other ways.
Part of the problem may be that people are watching television instead of exercising or doing other activities that burn more calories (watching TV burns only slightly more calories than sleeping, and less than other sedentary pursuits such as sewing or reading). But food advertisements also may play a significant role. The average hour-long TV show features about 11 food and beverage commercials, which encourage people to eat. And studies show that eating food in front of the TV stimulates people to eat more calories, and particularly more calories from fat. In fact, a study that limited the amount of TV kids watched demonstrated that this practice helped them lose weight — but not because they became more active when they weren’t watching TV. The difference was that the children ate more snacks when they were watching television than when doing other activities, even sedentary ones.
Stress and related issues
Stress and lack of sleep are closely connected to psychological well-being, which can also affect diet and appetite, as anyone who’s ever gorged on cookies or potato chips when feeling anxious or sad can attest. Studies have demonstrated that some people eat more when affected by depression, anxiety, or other emotional disorders. In turn, overweight and obesity themselves can promote emotional disorders: If you repeatedly try to lose weight and fail, or if you succeed in losing weight only to gain it all back, the struggle can cause tremendous frustration over time, which can cause or worsen anxiety and depression. A cycle develops that leads to greater and greater obesity, associated with increasingly severe emotional difficulties.
Drug side effects
Several prescription drugs can cause weight gain as a side effect by increasing appetite or slowing metabolism. These include corticosteroids such as hydrocortisone (used for a variety of conditions to reduce inflammation); estrogen and progesterone (used in oral contraceptives); anticonvulsants such as valproic acid (Depakote, others); certain anticancer medications; and drugs such as olanzapine (Zyprexa), haloperidol (Haldol), lithium (Eskalith, Lithobid), and clozapine (Clozaril), which are used to treat psychiatric conditions.
Illnesses that affect weight
A few illnesses that are characterized by an imbalance or an abnormality in your endocrine glands can also affect your weight. These include hypothyroidism (an underactive thyroid), polycystic ovarian syndrome, and certain unusual tumors of the pituitary gland, adrenal glands, or the pancreas.
Although they are the least likely cause of obesity.
In order to lighten up we at DIet science leader (DSL) determine the factors at play in your particular case and work to lighten up starting from that.
Its much easier to lighten up and maintain the weight lost forever if the cause is found and treatment targeted at the cause rather than just unscrupulous use of supplements or nutrients.
