How many people in the UK are overweight?

1 in 5 people in the UK are obese and about 2 in 5 adults are overweight.

How do I know if I am overweight and what is the difference between being over weight and obese?

Obesity is measured with a body mass index (BMI), a measure of body fat based on height and weight. It relates your weight to your height. If your BMI is over 25, but below 30, you are 'overweight'. If it is 30 or above, you are 'obese'.

What are the causes of being obese or over weight?

In most healthy people, the main causes of obesity are overeating and/or eating the wrong kinds of food; little physical activity; some people also inherit a tendency to be obese. Your weight gain can be a result of combination of all these conditions as well.

An unhealthy diet and physical inactivity are contributing factors to becoming overweight or obese.

If the amount of calories provided by your daily food intake is more than the calories that you burn off, your body will store the extra energy as fat. You can lose weight if you burn off more calories than you consume on a regular basis. The only guaranteed way to lose weight therefore is to eat less, do more and preferably both.

What are the side effects of being over weight?

An unhealthy diet and physical inactivity can increase your chances of getting heart disease, cancer, stroke, type 2 diabetes, high blood pressure, breathing problems, arthritis, gallbladder disease, raised cholesterol and osteoarthritis.

What are the side effects of being over weight as a women in particular?

For most women, carrying extra weight around their waists (larger than 35 inches) raises health risks like heart disease, diabetes, or cancer more than carrying extra weight around the hips or thighs.

What are the benefits of losing weight?

You are less likely to develop many diseases which are more common in overweight and obese people. Overweight and obese people are more likely to develop diabetes, high blood pressure, stroke, heart problems, some types of cancer, arthritis of the back and legs, gallstones, menstrual problems, incontinence of urine, breathing problems, some complications of pregnancy, and depression. If you are not overweight or obese, your chance of dying at any given age is reduced by about 20%. This is mainly because you are less likely to die from heart disease, stroke, diabetes, or obesity related cancers.

How can I lose weight?

The best chance of losing weight, and keeping the weight off is about eating a healthy diet and doing some regular physical activity. You can reduce weight either by reducing your calorie intake (e.g. by eating smaller portions) or by increasing your daily calorie requirement (beg by exercising more) or both. If you’re interested in a weight-loss program, it should encourage healthy behaviours that help you lose weight that you can maintain over time. Before you start a weight-loss program, talk to your doctor.

What is a prescription medicine for weight loss?

For obese people who have difficulty losing weight through diet and exercise alone, there are a number of NICE and FDA-approved prescription drugs that may help. All of the prescription weight loss drugs work by suppressing the appetite except for Xenical (orlistat).

Can I use prescription medicine for weight loss?

Weight reduction medications are not designed for cosmetic weight loss. They are designed to help obese patients, as part of an overall weight management program. They should not be used as a substitute for healthy eating and exercise. Prescription weight loss drugs are approved only for those with a BMI of 30 and above, or 27 and above if they have other risk factors, such as high blood pressure or diabetes. Before making any decision about using prescription pills to lose weight, you should ask your Doctor for a full explanation of your options.

In what conditions can I use weight loss pills?

Prescription weight loss pills are generally reserved for people who are unable to achieve or maintain a healthy weight through diet and exercise, and often have health problems as a result. You can be a candidate if other methods of weight loss have not worked for you, your BMI is greater than 27 and you have medical complications of obesity such as diabetes and high blood pressure.

What happens if I combine weight loss pills with exercise and diet?

Combining weight-loss drugs with a low-calorie diet and regular exercise can help you lose more weight than can either drugs or lifestyle changes alone. Combining all three — medication, fewer calories and more activity — can help you lose anywhere from 5 percent to 10 percent of your total body weight within a year.

What is a prescription diet pill?

Prescription diet pills are tablets that are prescribed by a Doctor for people that are considered to be seriously overweight or obese – in other words people who have a BMI of more than 30 (or 27 if they suffer from weight associated ailments such as high blood pressure and arthritis).

Which are the approved prescription pills in the UK?

Prescription diet pills can help those looking to lose weight that need a little help. For people suffering from extreme obesity, or dangerous weight-related health problems, prescription diet pills can alleviate the fears of getting started on a regular diet and exercise programme. You can buy prescription diet pills through our easy online consultation process.

There are two main kinds of approved weight loss drugs available in the UK, appetite suppressants (Reductil) and Lipase Inhibitors (Xenical Orlistat). Both have been subject to many clinical trials, and have been proven to accelerate the rate of weight loss for those people who combined use of the drug with a regular diet and fitness programme.

In the clinical trials, people using Xenical lost 10% of their body weight. Studies on Reductil found that 77% of participants taking the weight loss drug achieved weight loss that benefited their health.

What is Reductil and does it really work?

Sibutramine is an appetite suppressant that’s available on prescription in the UK under the brand name Reductil. Reductil is prescription slimming pill for people who suffer from extreme weight related problems. When Reductil was used in a study in combination with a healthy diet and exercise plan, 77% of the people in the study group lost weight and experienced health benefits.

Reductil is what's known as a appetite suppressant. That means it helps you to feel full. The active ingredient is sibutramine hydrochloride. It works by inhibiting the release and re absorption of seratonin by nerve cells. As a result of this, your seratonin levels increase. Seratonin creates a reaction in the brain that gives you the sensation of fullness. This means you're likely to eat less, and therefore you lose weight.

The weight loss pill Reductil should always be used in conjunction with a diet and exercise plan.

What is Xenical Orlistat and does it really work?

Xenical Orlistat works by blocking chemicals (enzymes) in your gut which digest fat. Nearly a third of the fat that you eat is blocked by Xenical orlistat. The undigested fat is not absorbed into your body, and is passed out with your faeces (stools). Studies have shown that, on average, Xenical orlistat plus a weight-reducing diet and exercise causes more weight loss than a weight-reducing diet and exercise alone. Some people lose 10% or more of their body weight within six months with the help of orlistat. In others, it is less effective.

Why prescription weight loss pills are better then non prescription weight loss medicine and pills?

Prescription weight loss pills can be bought only on prescription of a certified medical practitioner. These kind of diet pills are closely regulated and require approval of authorities. Weight loss pills such as Xenical (Orlistat) and Reductil (Sibutramine) are categorized as prescription weight loss pills because you need a registered Doctor's prescription before you can buy any prescription weight loss pill. A range of clinical tests are conducted to observe the effectiveness of these weight loss pills for weight reduction and to study their side effects.

What are weight loss supplements?

Non-prescription weight loss pills can be purchased over-the-counter and are subject to only minimal regulation by authorities. Non prescription pills are also called weight loss supplements.
