    What is weight loss treatment?

    It’s quite a clever thing really. Some weight loss products stop the fat in the food you eat from being absorbed. The fat comes out in your stool instead, and this allows you to lose weight.

    Other weight loss products act on the brain rather than your digestive system. They send signals to the brain indicating that you’ve had enough to eat. This stops you from overeating, and promotes weight loss.

    Who is weight loss treatment suitable for?

    Weight loss treatments are only suitable for people whose BMI (body mass index) is more than 30, or 28 if you have other risk factors like Type 2 diabetes or high blood pressure.

    You can check your BMI using our healthy weight calculator. The weight loss calculator will show you if you’re a healthy weight, and how much weight you need to lose to achieve a healthy weight if you’re overweight.

    The BMI range that’s considered healthy can vary depending on your ethnicity. Black, Asian and other minority ethnic groups with a BMI of 23 or more for example are more likely to get Type 2 diabetes and other long term illnesses. The NHS healthy weight calculator asks you what your ethnicity is, so this feature is included here.

    The calculator provides you with a personal calorie allowance, to allow you to get to a healthy weight in a safe way.

    If your BMI is below these numbers, and you’re overweight, a doctor will usually recommend making adjustments to your diet in the first instance, and increasing the amount of exercise you do. They may advise you to record what you eat in a food diary for one week. This can help them to monitor any particular habits that you have (such as putting sugar in your coffee) which you can change under their guidance.

    Similarly, in terms of exercise, it can be helpful to keep an activity diary, and to wear a pedometer for a week. A pedometer keeps track of the number of steps that you take and allows you to see how active you are on a daily basis.

    Once you have this information, it can help you to make changes to your lifestyle, and create a plan of action.

    How does weight loss treatment work?

    Certain weight loss treatments stop some of the fat that you consume from being digested, and this fat is instead released from the body in your stool. The active ingredient in these products attaches to enzymes that break down fat in the digestive system, and stops them from functioning as they normally would. Because this fat isn’t absorbed by the body, it allows you to lose weight. Weight loss products such as Orlistat, Xenical and Alli all work in this way.

    Other weight loss products work a bit differently. Treatments such as Mysimba and Saxenda act on receptors in the brain that control your appetite, causing you to feel fuller and less hungry. This can help you to eat less food, and reduce your weight.

    How we source info.

    When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.

    What types of weight loss treatment are there?

    From tablets to capsules to injections, there are a variety of weight loss medicines available. Which type of treatment is the right option for you usually depends on factors like how prone you are to certain side effects, if you’re currently taking other medicines which may interact with a particular type of weight loss treatment, or if you have certain health conditions.

    Which is the best weight loss treatment for me?

    It depends on your health background really. Weight loss treatments can have side effects, so if you’re likely to get particular symptoms, this may play a big part in which treatments are suitable for you and which aren’t. For example, Xenical is a capsule that can trigger severe diarrhoea, so you may be better off with a different product (although it should be noted that all weight loss products can cause diarrhoea).

    If you have certain health conditions, or if you’re currently taking certain medication, these can also have a big bearing on what the right treatment option for you is. Mysimba for instance isn’t suitable if you have high blood pressure or if you’re taking antidepressants.

    The type of treatment that you can use (or would prefer to use) is another factor. For example, Saxenda is effective but not everyone wants to use an injection. Xenical, Orlistat, and Alli are capsules, so if you’re able to take capsules and would rather take capsules, they may be the preferred options for you. Mysimba is a tablet, so if you can take tablets and you find them easier to swallow than capsules, for example, these products may be the best ones for you.

    Xenical, Orlistat and Alli

    Xenical, Orlistat and Alli all contain the same active ingredient, orlistat, and they all work in the same way in the body.

    There are a few differences though. Xenical is the branded treatment, and the more ‘famous’ weight loss product of the three. Orlistat is the generic version, and so it’s less expensive. Alli is a ‘pharmacy’ medicine, so you don’t need a prescription for it. But you’ll still need to answer a few questions from a pharmacist before you can get it. It’s the cheapest product of the three, but it contains half the dosage of Xenical or Orlistat (60mg rather than 120mg).

    Because Alli contains only half the dosage of Xenical and Orlistat, it stops the body from digesting less fat in comparison. Xenical and Orlistat normally prevent one third of dietary fat from being digested, whereas Alli usually stops about one quarter of dietary fat from being absorbed.

    If tablets and capsules aren’t suitable for you, Saxenda may be the right weight loss treatment. It’s an injection that you can take yourself, and you gradually increase the dose week by week until you reach the recommended dose.

    So to sum up: the right weight loss treatment for you may be dependent on a number of things. Our clinician can talk you through the various options though, factoring in your medical background and any health conditions or side effects that you’re prone to.

    Weight loss and diet

    If you’re overweight, it may be that changes to your diet, along with exercising on a regular basis, are the two measures that help you to reduce your weight to a healthy level (without the need for any medication).

    Having created a food diary and assessed what sort of dietary habits you can adjust on a day-to-day basis, you can start setting yourself realistic (and safe) targets. The British Dietetic Association recommends aiming for losing between 0.5kg to 1kg (1-2 Ibs) a week, and this is achievable by managing your daily calorie intake.

    If you’re trying to lose weight, it’s really important to do it at a gradual, sustainable rate. Trying to lose too much, too quickly by skipping meals altogether can lead to what’s sometimes called ‘yo-yo-ing’ (your weight fluctuating up and down), because the natural reaction to drastic ‘under-eating’ is ‘over-eating’. If you dramatically ‘under-eat’ as well, you might put yourself at risk of other health problems because your body won’t be getting the nutrients it needs.

    So in short, eating healthier things and controlling portion sizes will help you to lose weight and stay at a healthy weight (rather than skipping meals).

    Weight loss and exercise

    Exercise can help you to burn off excess calories that you don’t lose through making dietary changes alone, so combining the two is more effective than choosing one or the other.

    But exercise is also great for keeping your motivation levels up if you’re aiming to lose weight, and boosting your general wellbeing.

    Even just moving your body around burns more calories than sitting down, so even small things can make a difference.

    Increasing the amount of activity you do bit by bit is usually an effective way to approach exercise if you’re looking to lose weight, as it’s easier to make it part and parcel of your daily routine.

    In terms of how much exercise you should take in order to lose weight, more than 20 minutes of aerobic exercise at least three times a week is recommended. Aerobic activities are exercises that increase your heart rate, and really get your blood pumping. Walking, running, cycling, dancing and swimming are all examples, and using a treadmill or stair stepper too. But if you prefer weight training to aerobic exercise, this can also be effective for losing weight and burning calories.

    If you’re looking to lose weight quickly, around 60 minutes of moderate intensity, daily exercise may be effective. Brisk walking, riding a bike, water aerobics and even pushing a lawnmower are all moderate intensity exercises. Making simple changes to your lifestyle, like walking or riding your bike to work, using stairs instead of lifts, and parking further away from your destination are other easily achievable ways to lose weight.

    It’s important though to speak to a doctor if you’re overweight before you start a new exercise regime. You should aim to push yourself to begin with, but not too hard. Not only can this lead to injury, it may impact your motivation.

    Weight loss surgery: is it an option for me?

    It may be. And it can be very effective. But it’s not a small operation, and it’s normally only an option for people who haven’t managed to lose weight in spite of changing their diet and exercising on a regular basis.

    If you’ve not had success with these strategies, and you also have a BMI of 40 or above (or a BMI between 35 and 40 and an obesity-related condition that could benefit from surgery) you can discuss it with your GP. Surgery usually involves long-term follow-up with your GP too, to monitor your progress over an extended period of time.

    FAQ: Weight loss

    Have something specific you want to know about Weight loss? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

    Is Prolistat an approved treatment for weight loss?

    Yes. Prolistat is a safe and licensed weight loss tablet approved with a prescription. Our clinician will monitor you using it to make sure that it’s working the way that it should for you.

    Illegal diet pills, weight loss supplements or ‘fat burning tablets’ are widespread online, so you should always check you’re buying licensed medications from registered pharmacies.

    If you notice any issues with the treatment, or if you have any concerns, send us a message.

    Is Prolistat the same as Xenical?

    Xenical 120mg is a branded version of Prolistat. This means it contains the same active ingredient, and it works in the same way. The only real difference is branding and price, so it pays to compare the two before buying.

    As is the case with Prolistat, you will need a prescription to buy it, whether you’re buying it online or not.

    Are there other approved weight loss treatments?

    Yes. Certain weight loss treatments work in a different way, like Saxenda. Saxenda is an injectable weight loss medication that works by suppressing appetite. You only need to inject it once a day, so it might be a good option for you if you find that easier than taking tablets three times a day.

    Why should I buy Prolistat with Treated?

    We’ll help you to make an informed choice about the right weight loss treatment for you. Tell us about your health and we’ll recommend weight loss options that are safe and suitable. Choose your medication, and how regularly you’d like to receive it from us, and the quantity of it too. Change, pause or cancel your subscription anytime.

    At Treated, we think aftercare is just as important as the first consultation, so our clinicians will check in with you regularly to see how you’re getting on with your treatment. And if you’ve got any questions, just send us a message using your account.

    How long does Xenical take to work?

    This depends on many factors, but we’ll be able to monitor how it’s working for you and suggest any changes if they’re needed. If you’ve lost 5% of your weight within a three month period, there’s no threshold for how long Xenical will be prescribed for.

    If you continue to lose weight beyond six months, our clinician may recommend that you keep taking Xenical. This may be for up to one or two years, or longer still if you have a significant amount of weight to lose.

    Is there a meal plan I should follow when taking Saxenda?

    There isn’t a specific meal plan, but it’s important to follow a low calorie diet and get plenty of exercise while you’re taking Saxenda. Before you start taking it, a clinician can help you with this. Alongside exercise, following a healthy diet will make it more likely that your treatment is successful.

    The reference intake for women is 2,000 calories a day, and for men 2,500 calories a day. It’s generally recommended to aim for a calorie deficit of 500 calories per day to lose one pound per week.

    How safe is Mysimba?

    Mysimba weight loss tablets are effective and safe. That’s two good reasons to choose it. When compared to the health risks associated with obesity, or being significantly overweight and having other underlying conditions, it can help to improve your health considerably.

    As with any weight loss treatment, a little willpower and some lifestyle changes are key to its success. We can help you work out a plan to ensure that you get the best out of the treatment and keep the weight off.

    Is there such a thing as generic Mysimba?

    There isn’t a non-branded version of Mysimba available currently, although the medication is known by different names overseas (in the USA, it’s called Contrave).

    The active components in Mysimba are available in other medications. For example, Zyban, a stop smoking treatment, contains bupropion. But this isn’t suitable for use in weight loss.

    Mysimba, Xenical or Saxenda: what’s the difference?

    Mysimba shares some similarities with other treatments for weight loss. It’s a tablet, like Xenical, but works in a different way to this medication. Xenical, instead, works by preventing the body from digesting fat, which is eliminated without being fully processed by the body.  

    Like Saxenda, Mysimba has an effect on appetite, but the way the medication is administered is quite different (Saxenda is an injection).

    So which is better? It depends on a number of things: what you’ve used before, whether it was successful, and to an extent how much weight you need to lose and how quickly you want to lose it. Our clinicians can help you settle on the treatment that works best for you.

    How many calories should I eat to lose weight?

    It depends how much weight you want to lose. The NHS advises that most men should limit their calorie intake to no more than 1,900kcal a day, while most women should cap their calorie intake at 1,400kcal a day; and that to lose weight, on average, you should reduce your daily calorie intake by 600kcal.

    What works and what doesn’t can be an individual thing. Some general advice is to:

    • Consume three regular, balanced meals each day. Aim to eat at set times of the day and only snack if you’re physically hungry.

    • Look to eat more fruit and vegetables (at least five portions every day are recommended). A handful is about equivalent to one portion.

    • Fill half your plate with vegetables or salad and the other half with fish, meat, beans or eggs, and starchy foods such as rice, pasta, potatoes and bread.

    • Select foods and drinks that don’t have a high sugar content, and restrict any salty, sweet and fatty snacks.

    • Reduce your alcohol intake if you drink. Alcohol contains a lot of calories.

    • Try to drink two litres of fluid every day, and choose low calorie, non-caffeinated drinks (ideally without any artificial sweeteners).

    • Once you’ve eaten, wait for at least 15-20 minutes before deciding if you need to eat more.  It takes the brain this amount of time to work out if you’re full.

    You may be asking yourself what the best diet for weight loss is. There are plenty of them out there, but it’s important to flag up that some diets can be severe and might cut out foods that help to give you some nutritional balance. If you’re starting on a branded or franchised diet plan, make sure you do your research into it, and that the plan you’re on helps you to lose weight gradually and sustainably. And ask a doctor if you’re not sure. If a plan makes dramatic promises that sound too good to be true, they probably are.

    Do weight loss shakes work?

    It depends on the shake. Shakes that contain added sugars and syrups won’t help you to lose weight, but high protein shakes that contain fibre and no more than a couple of grams of sugar can be effective in the short term. In one study of weight loss shakes, patients lost an average of 13.8 pounds over 12 weeks.

    While many brands are rich in nutrients though, they’re not really a substitute for a healthy, balanced diet that contains whole foods. You may find that weight loss shakes help you to lose weight, but they’re not forcing you to alter your eating habits. So once you’ve stopped replacing your meals with shakes, it’s likely that you’ll put the weight that you’ve lost back on.

    To sum up: they can be an effective measure for weight loss for a period of time, and they are convenient because you can drink them ‘on the go’. But you may find that they’re not a long-term solution.

    What side effects can weight loss treatment cause?

    It can depend on the type of weight loss treatment you’re using, but the most common side effects are flatulence, increased and sudden bowel movements, fatty or oily stools, diarrhoea, constipation, headache and feeling sick.

    Not everyone gets these symptoms, but if you do, they normally occur shortly after eating a meal that’s high in fat. They’re a lot less likely to occur if you reduce the number of fatty meals you have, and side effects tend to ease once your body has adjusted to the treatment.

    Severe side effects are rare with weight loss treatments, but if you experience any signs of an allergic reaction (such as serious breathing difficulties, rash, itching, sweating, swelling in the face and throat, increased heart rate, nausea and vomiting) you should stop taking the treatment and seek emergency medical attention immediately.

    There have been reports of suicidal thoughts, suicide attempts and depression amongst patients whilst using Mysimba. If you get any thoughts of self-harm or other thoughts which cause you distress, or if you are feeling depressed, seek medical advice or go to hospital straight away.

    Although uncommon, patients using Saxenda have reported experiencing pancreatitis (inflammation of the pancreas). Pancreatitis is a potentially life-threatening condition, and you should go to hospital or get medical attention immediately if you develop severe and persistent abdominal pain which may spread to your back, and nausea and vomiting symptoms.

    In the first instance, if you get any side effects, you should always contact our clinician. They may advise you to try an alternative weight loss product, or to make further adjustments to your diet.

    Can you get weight loss treatments over the counter?

    The only licensed treatment that isn’t prescription only is Alli, which is available in pharmacies. You’ll still need to have a consultation with a pharmacist before you can get it though.

    Other weight loss treatments can have particular side effects that require an assessment from a clinician as to whether they’re safe for you to use, and are prescription only on this basis.

    We can help you find the treatment that works best for you, and issue a prescription for your preferred choice. Tell us about your health, and we’ll put together some options for you.

    Why should I buy weight loss treatment with Treated?

    We’re making weight loss treatment nice and digestible. Let us know about your health and our clinicians will advise you on suitable and safe treatment options. And you can choose which treatment you’d like from here.

    We like to give you plenty of flexibility too. So you can decide on how often you’d like us to deliver your treatment to you and the quantity of it as well. Change, pause or cancel your subscription at any point.

    If you’ve got any questions about your treatment, or if you’d like to make any changes, our clinicians are on hand to talk you through them. You just need to sign into your Treated account and send them a message. They’ll also get in touch with you regularly to see how you’re getting on with your weight loss treatment.

    Xenical or Prolistat: what’s the difference?

    Xenical is the branded treatment, so it’s more well known than Prolistat. Prorlistat, as is usually the case with generic treatments, is a bit cheaper. The appearance of the capsules, and the packaging they come in may differ too.

    But otherwise, both treatments contain the same active ingredient (orlistat) and work in very much the same way in the body.

    What should I do if Xenical doesn’t work?

    Let us know. We can advise you on alternative weight loss treatments if Xenical isn’t effective for you.

    It may be that making further changes to your diet and exercising on a regular basis may help. Our clinician may recommend that you keep a food diary and an activity diary for exercise to help them monitor your eating habits properly. Once our clinician has got this information to hand, they can help you to implement adjustments to your lifestyle and to create an action plan.

    Is Xenical safe to use?

    For most people, Xenical is perfectly safe to use, but it’s not suitable for everyone.

    Losing weight can impact on treatment doses for conditions such as diabetes and high cholesterol. If you’re using these medicines, it’s very important that you let us know.

    If you’re using any oral contraceptives, it’s advisable to use additional contraception if you’re taking Xenical, as it can trigger severe diarrhoea. This may compromise the effectiveness of contraception.

    Xenical is not suitable for children.

    Can I buy Xenical over the counter?

    Xenical is an S3 (pharmacist only medicine), meaning that while it’s available without a prescription, it's not exactly available ‘over the counter’. You’ll still have to consult with a pharmacy prescriber at the pharmacy before you can buy it.

    Why should I buy Xenical online with Treated?

    Talk to us about your health. We’ll get to know more about you, and our clinicians will offer you safe and suitable treatment options to choose from.

    Once you’ve selected your medication, you can also choose how frequently you’d like to receive it, and the amount of treatment each time too. Change, pause or cancel your subscription at any point.

    Our service doesn’t stop once your medication has been delivered. Aftercare is as important as the prescribing process, so if you’ve got any questions about your treatment, just send us a message. We’ll reach out to you on a regular basis to find out how you’re getting on with it.

    What if I take too much Saxenda?

    If you take too much Saxenda, seek immediate medical attention. Take the medication with you so the hospital can treat you quickly if needed. If you experience nausea, vomiting and hypoglycemia (low blood sugar) you should let a healthcare professional know as soon as possible. Early signs of hypoglycemia include fatigue, sweating, hunger, palpitations, shaking and mood swings.
