On social media and blogs, it’s sometimes claimed that levothyroxine can be used for weight loss. For people living with overweight or obesity, it can be confusing to know what’s actually true. This article explains the risks and what may be useful to know about levothyroxine and weight loss.

Modern medical treatment for overweight and obesity helps many people lose weight, improve their health, and maintain a lower weight over time. However, some experience side effects such as nausea, heartburn, or constipation. For most people, these symptoms are most common at the beginning of treatment and during dose increases. The side effects are usually mild and can often be prevented.

In the liver, fat is converted into ketones – an alternative fuel for the body and brain when carbohydrate availability is low. This state is called ketosis, or “keto” in everyday terms, and is an important part of the body’s ability to adapt to periods of limited energy availability. In this article, we explain ketones and ketosis – what they are, how they are produced, and why they matter.

Metformin is one of the most widely used medical treatments for type 2 diabetes. At the same time, this medication often appears in discussions about weight and metabolism. But why is metformin talked about in connection with weight loss, how strong is the effect really, and what risks do patients need to be aware of?

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.

‍

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.

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 and intermittent fasting are popular ways to lose weight and improve health – for example through 16:8 schedules and the 5:2 approach.

Intermittent fasting is a popular way to reduce energy intake for weight loss.

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) 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.

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 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.

According to the WHO, overweight and obesity affect nearly 60 per cent of the adult population in Europe, highlighting the need for integrated treatment strategies that combine medical therapy with lifestyle changes (1).

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).

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.

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.
