Today, more than 65 percent of adults in the United States are overweight or obese. Poor nutrition and physical inactivity account for some 300,000 premature deaths in the United States each year. Obesity puts people at increased risk for chronic diseases such as heart disease, type 2 diabetes, high blood pressure, stroke, and some forms of cancer. Obesity-related illness results in hundreds of thousands of preventable deaths each year in the United States and billions of dollars in health care costs.
Most health care professionals agree that men with more than 25 percent body fat and women with more than 30 percent body fat are obese. Some doctors estimate body fat by measuring the thickness of the layer of fat just under the skin in several parts of the body. Some use weight-for-height tables or Body Mass Index (BMI). However, both methods is inaccurate when measuring a body builder.
BMI = ____Weight____ X 703
(Height in inches) 2
Women typically collect fat in their hips and buttocks and men usually build up fat around their bellies. Excess abdominal fat is associated with increased risk of obesity related health issues. Women with a waist measurement of more than 35 inches and men with a waist measurement of more than 40 inches may have more health risks than people with lower waist measurements because of their body fat distribution.
This is a very simple question that most weight loss products will gloss over Fat is created in the body when the pituitary gland signals the body's metabolic glands to store energy (anabolic) instead of release energy (catabolic) The body uses hormones to determine the proper metabolic choice.
As one ages, Gonadal hormones decline dramatically While these hormones are related to sexual function, they are also heavily and primarily related to metabolic rate, ATP (Energy) availability to cells, and muscle tone and development This decrease in Androgens in the body will result in les energy burn and increased fat.
Simultaneously, your body will increase production Sex Hormone Binding Globulin (SHBG) SHBG is directly related to the storing of energy in fat cells It also absorbs free Androgens and binds it to the fat that is formed This result in an even lower metabolic rate and energy.
Growth Hormone stimulates protein synthesis, tone muscle, strengthen of bones, effectively burn fat as fuel, and regulate healthy blood glucose level.
Thyroxine is a hormone produced by the thyroid gland. Thyroxine raises the metabolic rate. This increase in "metabolism" helps you to feel more energetic, burn more calories, and is important in weight loss. Blood levels of thyroxine increase by about 30% during exercise and remain elevated for several hours afterward - this period of time is increased by an increase in intensity and/or duration of exercise. Regular exercise also increase thyroxine levels at rest.
The reason most people become overweight or obese is fairly simple: by taking in more calories than they need on a regular basis. Those surplus calories that you do not use are converted into extra weight and is stored in your body as fat.
Lack of sleep may also contribute to obesity. Recent studies suggest that people with sleep problems may gain weight over time. Certain medication such as steroids and antidepressants also contribute to obesity. It may slow the rate at which the body burns calories, stimulate appetite, or cause the body to hold on to extra water. Other factors such as certain illnesses, genetics, emotional eating, environmental factors, physical inactivity, may also lead to weight gain.
Genetic Factors: Obesity tends to run in families, suggesting a genetic cause. However, families also share diet and lifestyle habits that may contribute to obesity. Healthcare professional suggest that people with family history of heart disease and diabetes should try to maintain a healthy BMI.
Environmental and Social Factors: Environment strongly influences obesity. Environment includes lifestyle behaviors such as what a person eats and his or her level of physical activity. Too often Americans eat out or get take out, consume large meals and high-fat foods, and put taste and convenience ahead of nutrition. In addition, we are eating too much fast food and processed food that cost less and easier to find and prepare than healthier foods, such as fresh vegetables and fruits. Also, most people in the United States do not get enough physical activity and more people drive instead of walk. Inadequate access to safe recreation places or the cost of gym memberships is also limiting opportunities for physical activity.
Being obese causes an increased risk for developing a number of serious and potentially lethal health problems, including: hypertension/high blood pressure, Type 2 diabetes, heart disease and stroke, High blood cholesterol, Osteoarthritis, infertility, sexual dysfunction, and emotional instability.
Who Should Lose Weight?
Health care providers generally agree that people who have a BMI of 30 or greater can improve their health through weight loss. This is especially true for people with a BMI of 40 or greater, who are considered extremely obese. Preventing additional weight gain is recommended if you have a BMI between 25 and 29.9, unless you have other risk factors for obesity-related diseases. Obesity experts recommend people with family history of heart disease and diabetes should try to maintain healthy BMI to avoid these health issues. Men who have waist circumferences greater than 40 inches, and women who have waist circumferences greater than 35 inches should try to lose weight. People with high blood pressure and high cholesterol level should also lose weight.
Exercise and Weight Loss
Weight control is a life-long effort. Eating a healthful diet and getting at least 30 minutes of moderate-intensity physical activity, 7 days a week have important health benefits. Sixty minutes of physical activity a day may be required to prevent gradual weight gain in adulthood. Previously overweight and obese individuals are encouraged to get 60 to 90 minutes of exercise a day to sustain weight loss.
Eurycoma Longifolia— The bioactive compound—Eurypeptides is shown in research to increase the CYP17 enzyme, an enzyme responsible for converting cholesterol into other useful hormones such as DHEA, Cortisol, and Testosterone. The Eurypeptides has been scientifically proven to increase Androgen production, decrease SHBG, and increase ATP production in the muscles. In addition, Eurypeptides increase IGF1 and Thyroxine level. Research has shown Eurypeptides to increase the body basal metabolism rate, which account for 60% of the calories burnt each day. These translate into better weight management.
Rosavin from Rhodiola rosea –Research found that Rosavin -- an active compound found in rhodiola activate hormone-sensitive lipase, that is capable of breaking down fat stored in adipose tissue, thus increasing the breakdown of fat stored in adipose tissue. In human clinical studies, administration of rhodiola rosea extract, in combination with moderate exercise, produced significant weight loss.
4-hydroxyisoleucine from Fenugreek - Fenugreek has a long history of folk use throughout Asia and the Middle east as an anti-diabetic. It is an adaptogen that help regulate the insulin production in responding to the body’s need. The active compound, 4-hydroxyisoleucine stimulates insulin secretion, effectively converting blood glucose into energy, thereby helped in reducing the production of body fat. The science on fenugreek on the cholesterol-lowering, blood lipid-lowering and anti-diabetic activities appear to be linked to the presence of soluble fibers, the galactomannans, which has shown fat-sequestering properties by binding to the dietary fat and reducing its absorption into the body.
Yerba Mate’ (Ilex paraguariensis) – The leaves of Yerba Mate contain caffeine, theobromine, and two methylxanthines which boost metabolism. Yerba Mate’ drink helps alleviate fatigue, suppress appetite, stimulate body and mind, and boost metabolism. Current science on Yerba Mate’ shows that a decoction of the leaves enhances bile flow and speeds intestinal transit time. Like caffeine, theobromine is a central nervous system stimulant alkaloid, a strong cardiac stimulant, smooth muscle relaxant, and diuretic. A standardized Yerba Mate’ extracts that contains 0.2% theobromine, enhanced metabolic, diuretic, and appetite-suppressing properties. Yerba Mate’ is great for those who wish to suppress appetite, boost metabolism and achieve a leaner body.
Green tea catechins, a class of polyphenols, are known to promote weight loss by increasing the metabolism of fats by the liver (thermogenic effect), inhibiting lipase (fat absorption enzyme) in the digestive tract, and providing a feeling of satiety and fullness. Catechins do not function as a stimulant.
Five independent clinical trials with at total of 500 subjects have documented that green tea catechins have reduced body weight, especially abdominal body fat. These results were even more dramatic in obese subject, who observed a greater reduction. In one particular double-blind study involving 80 subjects, the Green Tea treatment group received 588 catechins daily and showed a significant (P<0.01) weight loss of 1.7kg in 12 weeks.
