FAQs

A:

Obesity can be defined as an excess accumulation of body fat sufficient to endanger health. It is a disease (not a personal weakness) that requires long-term management to achieve and sustain weight loss

Experts agree that the main cause of obesity is people taking in too many calories, generally in high-fat or sugary foods, with not enough calories being used up through physical activity. Obesity results from too many calories being consumed, with too few being used up. The body starts to store these excess calories in the form of fat.

A:

Obesity is associated with an increase in serious health risks including the following:

•    High blood pressure
•    Diabetes
•    Heart disease
•    Stroke
•    Certain forms of cancer
•    Osteoarthritis

If you have a question about obesity or your personal health, check with your doctor.

A:

The most widely accepted measurement of obesity is known as the body mass index (BMI). BMI is calculated by weight (kg) divided by height (in metres) squared.

BMIs are graded as follows:

• BMI < 18.5 (underweight)
• BMI 18.5-24.9 (desirable weight)
• BMI 25-29.9 (overweight)
• BMI 30-39.9 (obese)
• BMI ≥40 (severely obese)

Other methods of measuring obesity used by healthcare professionals include:

• waist circumference — measuring how much fat is stored in the stomach area, which is well known to be closely linked with the risk of developing heart disease.
• height-weight ratio — using an appropriate measurement of a person’s frame size — small, medium, large — height/weight tables can be used to estimate ideal weight.
• measuring the percentage of body fat — using the skin fold test.

No. You should not take alli if your BMI is less than 28. alli is used for weight loss in adults who are overweight with a BMI of 28 or above. Use the BMI calculation tool on the alli website now to find out your BMI and see if it’s in the right category for you to use alli. (You need to know your weight and height.)

Alternatively, you can ask your pharmacist to work out your BMI, or use the chart below to see if alli can help you lose weight and so improve your health. Find your height on the chart and if you weigh less than the weight shown for your height, do not take alli.

If you are overweight, yes. Obesity experts in the UK agree and widely available research demonstrates that moderate weight loss is beneficial to your health. Achievable, realistic weight loss of 5% can result in significant improvements in overall health, including decreased risk of heart disease.

Slow, steady weight loss is the healthy way to reduce body fat. The alli programme helps you lose weight gradually and shows you how to sustain your goals over the long term, if you’re prepared to make positive lifestyle changes.

A:

alli is designed to help you to lose weight. It should not be taken for more than six months.

If you have lost some weight by taking alli but are not losing any more, you may need to re-set your calorie and fat targets, taking into account your current weight and activity level.

If you are satisfied with the weight loss you have achieved, continue to follow a reduced calorie, lower-fat diet and keep up your activity levels. People who lose weight and maintain the loss make long-term lifestyle changes, which include changes to what they eat and how active they are.

No. alli is only for overweight adults with a BMI of 28 or more.
