Polyfill.io vulnerability

28 june 2024

Our eHealth team advised us yesterday of an international vulnerability relating to polyfill.io . This domain has become compromised and is  spreading malware through a widespread supply chain attack, estimated to affect over 110,000 websites including major websites such as the BBC. The Polyfill site offered widely used bits of code for older browsers that allowed the use of modern Javascript features. Such code makes the work for web developers easier and allows compatibility with a broader range of browsers. 

Websites that have used the Javascript code from Polyfill have been urged to remove such code immediately. The change occurred after a suspected Chinese firm purchased the domain in early 2024.

Tactuum have identified and are now testing a fix to remove all Polyfill code from the RDS site.. They will be deploying the fix on Monday 1 July along with other planned fixes and amendments. I will notify you of the timing  of the deployment as soon as possible.

In the meantime, please ensure that you have up-to-date anti-virus software installed on your machines and personal devices.

 

Managing my weight

Your weight plays a large role in  your risk of developing  type 2 diabetes, especially if your extra weight is around your waist.

What is a healthy weight to aim for?

This is about working out your Body Mass Index (BMI).  BMI uses your height and weight to work out if you're a healthy weight.  You can work your BMI out for yourself using this NHS tool  – it will show you your target range.

For many people living with obesity, aiming for a healthy BMI may not be realistic. Research shows that  even losing just 5% of extra weight will improve your health. The more weight you lose, the greater the health benefits.

What is a healthy waist size?

BMI  doesn’t look at how much fat you have around the middle. That is why you need to measure your waist too.

Healthy weight size all depends on your gender and ethnicity. For a healthy measurement you need to aim to be less than:

  • 80cm (31.5in) for all women
  • 94cm (37in) for most men
  • 90cm (35in) for South Asian men.

This video from Diabetes UK shows you how to measure your waist size.

 

Diet plan options to lose weight

There are a lot of different ways to lose weight – but there’s no one-size-fits-all diet.

It starts with finding a way to eat fewer calories than you use. A calorie (or kcal) is a unit of energy, which is in the food and drink we consume. Your body uses energy for everything we do – from breathing and sleeping to exercising. When you eat, you’re replacing the energy you’ve used, which helps you to maintain a healthy weight.

As a general guide, government recommendations are that men need around 2,500kcal a day to maintain a healthy weight, and women need around 2,000kcal a day. But most people need different amounts of calories based on how their bodies work, how active they are and any weight management goals.

A range of diet options is listed below, with links to menu plans from Diabetes UK. Research suggests that the best type of diet is one that you can maintain in the long term, so it's important to talk to your healthcare professional about what will work for you. 

With any weight loss diet it is important to speak to your healthcare team first as it may impact on your health conditions or medication.

What is the evidence for different types of diet?

Researchers have examined all the evidence on which diets help people with type 2 diabetes to lose weight. They found that low-calorie meal replacement diets helped people to lose more weight than other types of diets and gave people with type 2 diabetes the best chance of going into remission. 

The research showed that people with type 2 diabetes who went on a very low-calorie diet of around 400-500 calories a day for 8-12 weeks  lost the most weight. This type of diet involves swapping your usual meals for a short period with total diet replacement products, often soups, bars and shakes, that are carefully designed to provide the vital nutrients your body needs. Normal foods are then gradually introduced

This type of diet on average helped people lose 6.6kg more weight compared to food-based low-calorie diets of around 1000-1500 calories a day. This is because very low-calorie meal replacement diets provide fewer calories. 

The evidence also showed that low carbohydrate diets did not lead to greater weight loss than higher carbohydrate, low-fat diets.

High-protein and Mediterranean, diets all led to only a small amount (between 0.3-2 kg) or no weight loss compared to other diets tested, but the researchers found the evidence on these diets was of poor quality.

Support from healthcare professionals

The people who took part in the study were supported through their behaviour change and to stay on the trial diet. If you want to follow a similar diet, it's very important to get support from your healthcare team to make sure it's safe and suitable for you.

A healthy balanced diet

A healthy diet is all about variety and choosing different foods from each of the main food groups every day. This variety is essential, as no single food contains all the essential nutrients your body needs.

The main food groups are listed below, with links to more information from Diabetes UK:

Low carb diet

Eating a low-carb diet means cutting down on the amount of carbohydrates (carbs) you eat to less than 130g a day.

But low-carb eating shouldn’t be no-carb eating. Some carbohydrate foods contain essential vitamins, minerals and fibre, which form an important part of a healthy diet. 

It’s really important to first reduce your carb intake from unhealthy sources such as sugary drinks, pizzas, cakes, biscuits, chips, white bread, fruit juices and smoothies.

And it is a good idea to get your limited carbs from healthy high-fibre carb foods, such as pulses, nuts, vegetables, whole fruits and whole grains.

Benefits and risks

One of the main benefits of following a low-carb diet is weight loss. This helps to reduce HbA1c and blood fats such as cholesterol. For people with prediabetes, losing weight can reduce your risk of developing type 2 diabetes, and a low-carb diet is one option to help you do this.

However, there’s no evidence that following a low-carb diet is any more beneficial in managing diabetes than other approaches in the long term, including a healthy, balanced diet.

Depending on the approach, following a low-carb diet may also lead to  side effects, such as constipation or bad breath. Although these can be unpleasant, they are usually temporary and shouldn’t be harmful in the long term. Speak to your healthcare professional if you’re concerned about any of these.

You can help make sure you're getting the calcium you need by including unsweetened milk and yoghurt in your diet too. 

Meal plan 

Diabetes UK provides a 7-day low-carb meal plan that you can try.

Mediterranean diet

Mediterranean diets have been associated with reduced risk of high blood pressure and cholesterol which are risk factors for heart disease. A Mediterranean style diet can therefore provide a great option for people at risk of diabetes, as it could help reduce the risk of heart-related diabetes complications.

There’s also evidence to show that the Mediterranean-style diet can promote weight loss and improve blood glucose management.

A Mediterranean diet includes a lot of fruits and vegetables, beans and pulses, nuts and seeds, wholegrains and olive oil. It also includes some dairy (milk and yogurts), lean protein like chicken, eggs and fish, in moderation. Red meat and processed foods are included in much smaller amounts, and wine is included in moderation.

Diabetes UK provide a 7-day Mediterranean diet meal plan that you can try.

Lower calorie diet plans - e.g. 1200 or 1500 kcal per day

Diabetes UK provide a range of low calorie meal plans for men and women, Including vegetarian options.

 

Low calorie and very low calorie diets

A low-calorie diet is made up of between 800 to 1200 calories a day. A very low-calorie diet means having less than 800 calories a day. 

Most people who follow these diets use special meal replacement products, likes soups and shakes, which are nutritionally complete. If you chose to try a low-calorie diet, speak to your GP, nurse or dietitian first.

These are short-term diets. You would usually have the soups or shakes for about 12 weeks, then gradually reintroduce normal, healthy food again.

This type of diet isn't right for everyone. You need to talk to your doctor before starting a low-calorie diet, so you can be sure that it's safe and could work for you.

It may sound obvious, but this diet isn’t easy. You'll need a lot of support from your doctor and other healthcare professionals, as well as the people around you.

Benefits and risks of a low-calorie diet

Your doctor can talk to you about the benefits and risks of a low-calorie diet.

A low-calorie diet can have side effects, including:

  • constipation
  • dizziness
  • headaches.

These side effects often go away after a while, but it's important to talk to your doctor if you have any of these, so they can keep a close eye on you.
