You can use a measurement called a body mass index, or BMI, to decide whether your weight is dangerous to your health. The BMI is a combination of your height and weight. If you have a BMI of 30 or higher, your extra weight is putting your health in danger. Where you carry your body fat may be as important as how many extra pounds you have. People, who carry too much fat around the middle, rather than the hips, are more likely to have health problems. In women, a waist size of 35 in.(88.9 cm) or more raises the chance for disease. In men, a waist size of 40 in.(101.6 cm) or more raises the chance for disease.
Abdominal fat is more dangerous than other fat in your body. They wrap around your organs and affect their function. If you are in apples shape (most fat store in your waist than other body part), you are in much higher risk to develop health problems related to obesity.
Don´t try to lose weight when you are not in a range of obesity or overweight. Try to keep your weight near normal range. Optimal is around 22 BMI. If you are overweight, change your eating habits and try to lose weight slowly.
Don ´t check scale everyday. Instead, check scale regularly, once or twice a month.
