Low-GI foods: recipes and guide
The GI method was originally developed to help people with diabetes, but has since become a popular approach for healthier eating and more stable blood sugar levels. GI (glycaemic index) describes how quickly carbohydrates are broken down and absorbed into the bloodstream – the lower the GI, the more slowly blood sugar rises. In this guide, we explain what low-GI foods are and share practical tips for creating meals with a lower glycaemic index.
Low-GI foods: advantages and disadvantages
The concept of the glycaemic index (GI) was introduced by researcher David Jenkins and his colleagues more than 40 years ago as a way to describe how carbohydrates affect blood sugar. Foods with a low GI produce a slower, more even rise in blood sugar, while foods with a high GI raise blood sugar more quickly. In this article, we go through how GI works, what the research says, and the pros and cons.
Ketosis weight loss per week: guide and long-term goals
In the early 20th century, doctors discovered that ketosis – a state in which the body uses fat as its main source of energy – could reduce severe epileptic seizures. Today, the ketogenic diet is best known in the context of weight loss and health, with promises of rapid weight loss and improved metabolic health. But what actually holds true? In this guide, we explore the relationship between ketosis, weight loss, and health.

Fasting for weight loss: guide, risks and benefits
Fasting and intermittent fasting are popular ways to lose weight and improve health – for example through 16:8 schedules and the 5:2 approach. Many people experience better appetite control and a clearer daily structure, but the method is not suitable for everyone and may involve risks. In this guide, we go through what fasting is, its potential benefits and risks, and how it can be combined with Yazen’s comprehensive treatment for overweight and obesity.
Intermittent fasting for weight loss: how it works, benefits, and risks
Intermittent fasting is a popular way to reduce energy intake for weight loss. For some people, it can be a helpful support on a weight journey, but it’s not right for everyone and needs careful thought to be safe and sustainable. In this article, we look at how intermittent fasting works, potential benefits, and risks you should be aware of.
Myths and facts about obesity
There are many myths and prejudices surrounding overweight and obesity. They are deeply rooted in society and can create guilt, shame and misunderstanding, despite obesity being a complex medical condition influenced by biology, environment and living conditions. When myths dominate the conversation, they obscure what actually helps. In this article, we address common misconceptions and highlight knowledge that truly makes a difference.
Body mass index (BMI), body measurements and body composition – why Yazen uses multiple measures
Body mass index (BMI) is a commonly used measure of the relationship between weight and height in weight loss and obesity treatment, but it does not provide the full picture of your health. At Yazen, we therefore complement BMI with body measurements and body composition to gain a better understanding of your body and develop more individualised strategies for sustainable weight loss.
Boost your metabolism – how it works and how you can influence it
Every second, your body uses energy. Your brain needs fuel to think, your heart to keep beating, and your lungs to fill with air. Even when you are lying still, your body is constantly working in the background. All of this requires fuel. Metabolism, also known as metabolic rate, is the process by which the body converts food into energy.
Effective fat burning: a guide for those who want to burn fat the right way
Effective fat burning isn’t about extreme methods – it’s about understanding how the body uses energy, how you can increase your expenditure, and how to build habits that last for more than just a few weeks. Many people who want to lose weight think they need to do everything “perfectly”, but in reality it’s about finding long-term, sustainable strategies combined with training, nutrition, and more daily movement.
Beyond GLP-1 medicines: the path to successful and long-term weight loss
We are in a new era of obesity treatment. GLP-1-based medicines have transformed the landscape – but real success is achieved when medication becomes part of a comprehensive approach that supports the whole person.
Long-term health and weight loss require more than medicine alone. It is when medical treatment is combined with lifestyle change and continuous guidance that meaningful, lasting progress becomes possible (1–2).
Trulicity and Medical Weight Loss: How Treatment with Dulaglutide Works
Trulicity is a prescription medication containing the active substance dulaglutide. It belongs to the group of GLP-1 receptor agonists and is used for the treatment of type 2 diabetes.
Dulaglutide mimics the effect of the body's own hormone GLP-1, which helps regulate blood sugar. The medication can also affect appetite and satiety, which can lead to some weight loss.
Saxenda (liraglutide) in the Treatment of Obesity
Saxenda is a daily injection treatment with liraglutide that can reduce appetite and increase the feeling of fullness. It is used for overweight and obesity, combined with diet and exercise. The dosage is stepped up gradually to reduce side effects such as nausea.
How to reduce the risk of loose skin after weight loss
Weight loss can bring significant positive changes for both health and wellbeing. At the same time, many people experience loose skin after substantial weight loss, especially if the weight has decreased rapidly or if they have lived with overweight or obesity for a long time.
Loose skin is a natural result of changes in the skin’s elasticity as the body adjusts. By understanding how the skin is affected after weight loss and which factors influence its elasticity, you can give the skin better conditions to tighten and feel firmer again.
Ozempic (semaglutide) for the treatment of obesity
Ozempic is a prescription medication used for the treatment of type 2 diabetes as a supplement to diet and exercise. The active substance, semaglutide, contributes to improved blood sugar control and also has an appetite-suppressing effect, which can lead to weight loss.
Wegovy (semaglutide) in the Treatment of Obesity
Wegovy is a prescription medication used for the treatment of obesity and overweight.
It contains the active substance semaglutide and has shown significant effects on weight loss and cardiometabolic risk factors in clinical studies. By affecting the body's appetite regulation, this treatment can lead to an increased feeling of fullness and reduced energy intake.
Blood pressure – a guide to normal levels, high, and low blood pressure
Blood pressure shows the force of the blood as it is pumped out into the blood vessels. Both high and low blood pressure can affect your health negatively, but high blood pressure is of particular concern. If blood pressure remains elevated over a longer period, it increases the strain on the blood vessels, which raises the risk of cardiovascular disease.
Weight loss and healthy lifestyle habits — such as eating a nutritious, balanced diet, being regularly physically active and reducing alcohol intake — can often help lower blood pressure, but in some cases medication is also required.
Are weight loss and fat loss the same thing?
Many people who want to improve their health talk about “losing weight” – but what does that actually mean? Is the goal to weigh less, or to have less body fat? The difference is crucial for both health and results. To choose the right strategy, you need to understand the distinction between weight loss and fat loss. Even though they may sound like the same thing, they have different effects on our bodies and our health.
