First question before start loosing Weight is how much should I weight?
To determine how much you should weigh (your ideal body weight) several factors should be considered, including age, muscle-fat ratio, height, sex, and bone density.
Some people suggest that calculating your Body Mass Index (BMI) is the best way to decide whether your body weight is ideal. Others say that BMI is faulty as it does not account for muscle mass and that waist-hip ratio is better.
Body Mass Index (BMI) a good measure
Your BMI is your weight in relation to your height.
BMI metric units: Your weight (kilograms) divided by the square of your height (meters)
e.g. Weight 80 kilograms. Height 1.8 meters.
1.82 meters = 3.24
80 divided by 3.24 = BMI 24.69.
Imperial units: Your weight (pounds) times 703, divided by the square of your height in inches.
e.g. Weight 190 pounds. Height 6 ft (72 inches)
722 = 5184
190 x 703 divided by 5184 = BMI 25.76
Health authorities worldwide mostly agree that:
People with a BMI of less than 18.5 are underweight.
A BMI of between 18.5 and 25 is ideal.
Somebody with a BMI between 25 and 30 is classed as overweight.
A person with a BMI over 30 is obese.
People can lose weight for many reasons, perhaps intentionally through exercise training for a sports event, for health reasons, just to look better, or unintentionally as may occur because of an underlying disease. Weight loss refers to the loss of body fat (adipose tissue), fluid and/or lean mass. Lean mass are parts of your body without fat, such as bone mineral deposits, tendons, connective tissue and muscle.
Here is new research on loosing Weight with Green Coffee Beans
Scientists report striking new evidence that green, or un-roasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time.
In a study presented at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, Joe Vinson, Ph.D., and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.
"Based on our results, taking multiple capsules of green coffee extract a day - while eating a low-fat, healthful diet and exercising regularly - appears to be a safe, effective, inexpensive way to lose weight," Vinson said at the ACS meeting, being held here this week. He is with the University of Scranton in Pennsylvania. The study involved 16 overweight or obese people aged 22-26 years who took capsules of the extract or capsules containing a placebo, an inactive powder, for a total of 22 weeks. The subjects alternated between a low dose and a higher dose of the extract. The low dose consisted of 700 mg of the coffee extract, and the high dose was 1,050 mg. It was a so-called "cross-over" study in which people cycled through the two doses and the placebo, each for six weeks. Such studies have advantages because each person serves as his or her own "control," improving the chances of getting an accurate result.
All of the participants were monitored for their overall diet (calories, food eaten, etc.) and exercise over the study period. "Their calories, carbohydrates, fats and protein intake did not change during the study, nor did their exercise regimen change," Vinson said. Participants lost an average of 17 pounds during the 22 weeks of the study. It included an average of a 10.5 percent decrease in overall body weight and a 16 percent decrease in body fat. Vinson noted that weight loss might have been significantly faster, except that participants received the placebo and the lower dose of green coffee extract for part of the study period. Vinson pointed out that previous studies have shown weight loss with green coffee. But this was the first to use higher amounts of the coffee extract and the first to measure the response to various doses. Based on those studies, Vinson believes that green coffee beans' effects likely are due to a substance called chlorogenic acid that is present in unroasted coffee beans. Chlorogenic acid breaks down when coffee beans are roasted (usually at a temperature of 464-482 degrees Fahrenheit). Roasting gives coffee beans their distinctive color, aroma and flavor. Green coffee beans, in contrast, have little aroma and a slightly bitter taste.
