the adverse health effects associated with overweight and obesity require no further mention because we now know, the conditions for almost every ailment, physical and mental are linked. From heart disease to arthritis and some cancers, and from the body-image issues to low self-esteem and depression. “The general environment makes it harder for people to be physically active, and the development of labor-saving machinery – equipment for the home, cars, motor bikes and so on – allow people to do things that 50 years would have required much more energy, “he adds. Tipping the energy balance, so our energy from the food less than what we consume through physical activity is the key to any diet plan. A very low calorie diet is one of the ways to create this deficit, “says Leeds. While other weight loss diets , including low-calorie diet (LCD) is recommended to eat 800-1500 calories a person per day, very low calorie diets (VLCDs) recommend an energy intake of only 450 to 800 calories per day, “he says. “These are fortified liquid meals that provide all the vitamins, minerals, trace elements and essential fatty acids that are required on a daily basis.” He explained that if a diet of ordinary foods contains 450-800 calories, is elected, it is not possible, all micro-nutrients will be needed. “In this program, not the individual food, other food, but after the diet, they have gradually before the re-introduction of food made.” But how long can a person on to manage such a low calorie intake? Leeds says that, although a number of studies, which lasted for 16 weeks, the formal guidelines recommend VLCDs United Kingdom for not more than 12 weeks in the rule. “Once they pass through this period has to be taken to ensure the supply of energy. And then, need to go on a maintenance diet, because it is not possible, and certainly not appropriate for people at low levels that over the length of time that we recommend to stay, “he explains. On the criticism that people usually return to their weight goes off VLCDs explains, Leeds, that it just because it is not going to, or follow the appropriate maintenance diet. should be The amount of calories a person take on a maintenance diet depends on the amount of weight loss within reach of those 12 weeks. For each kilogram of weight lost during the program , you have your regular supply of energy (calories your normal inkate before the Diet of) reduce by 25 calories. This means that if you lose 10kgs on a VLCD, you would need 250 calories less than what you were before eating the diet to maintain weight loss to take. This is because, for each kilogram of weight lost is gone, there are some metabolically active lean tissue lost to her, says Leeds. “Therefore, the energy of the body is going down.” There are some side effects of this diet that are associated with weight loss. Constipation and an increased risk of gout and gall stones are sometimes seen in people going VLCDs. Some people have cold hands and feet, and develop bad breath if they generate on the diet is the body’s physiological response and to save energy But this does not seem to know there Obesity and obesity epidemic. There are some specific medical cause of obesity (eg thyroid problems), but in large populations, is obesity is usually caused by an imbalance of energy in the body compared to the energy used by the body, says obesity- Researchers and medical director of Cambridge Health and Weight Plan UK Professor Anthony R. Leeds. How modern conveniences cause us to eat more and move less, we are on more than we can lose pound package.
