Orlistat is a lipase inhibitor that reduces the dietary fat absorbed by the intestines by about 25%. These unabsorbed fats exit the body through bowel movements, resulting in more weight loss.

The medication can also reduce visceral fat, which is more harmful than subcutaneous fat and increases the risks of high blood pressure, heart disease, strokes, and type 2 diabetes.

Alli can provide additional support if you're struggling to lose weight by eating and exercising alone. However, it's not a miracle drug and can only be effective when combined with a healthy lifestyle.

The recommended BMI falls between 18.5 and 24.9 - with BMIs of 25 to 29.9 being classified as overweight. People with a BMI of 30 or over are classed as obese and have a high risk of numerous health conditions.

Taking Alli can enhance your weight loss efforts and help you eat healthier. It's an excellent option if you're ready to make positive changes and improve your health. However, the side effects of eating high amounts of fat while using Alli can put some people off.

Alli comes in capsule form and is usually taken three times each day—during meals or within an hour after consuming a meal. As it reduces your dietary fat intake, Alli won't have much effect unless your meals contain some fat.

Eating a low-fat diet can enhance your weight loss efforts, and Alli provides extra support by reducing the amount of fat your body absorbs from each meal. Eating high-fat meals, including greasy foods and baked goods, can result in unpleasant side effects, including urgent bowel movements.

We recommend using multivitamins while taking Alli, as it might block your body's ability to absorb vitamins and minerals.

If you're taking other medicines, please check whether Alli suits your needs with a doctor or registered pharmacist. The fat blocker can cause interactions with other medicines, including thyroid and diabetes treatments - reducing their effects.

Avoid Alli if:

• You've had an organ transplant (it can interfere with anti-rejection treatments).
• You're taking cyclosporine.
• Your Body Mass Index (BMI) is under 28
• You're pregnant/breastfeeding.

Alli is only recommended for people aged 18 and over due to its fat-blocking effects. Childhood obesity is an ongoing issue in the UK, but there are treatments and lifestyle support available to encourage healthy weight loss in young people.

Some people notice changes within a few weeks of starting Alli, but it can take longer. The treatment is designed to offer weight loss support, and most people notice gradual results when they restrict their fat intake and combine exercise with dieting.

You should witness noticeable results within six months of beginning treatment, but it depends on whether you follow the instructions.

When combined with a low-fat, calorie-controlled diet and regular physical activity, Alli can help you lose approximately 1 to 2 pounds weekly. Again, this depends on whether you remain in a calorie deficit and integrate Alli with a healthy lifestyle.

Please consult your doctor before combining Alli with other medications and supplements. It might cause interactions, resulting in side effects. In some cases, Alli can impact how other medications work, and your doctor might need to increase the dosage.

Due to potential interactions, using Alli in combination with other weight-loss products is not recommended. If you use protein shakes or meal replacements, please review the fat content before taking them with Alli.
