L-glutamine is an amino acid often sold as a supplement for training and recovery. More recently, it has also been mentioned in connection with weight loss. But is there actually evidence that L-glutamine can help you lose weight? In this article, we go through what the research shows and clarify common claims about L-glutamine.

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.

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. 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 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.

It’s easy to be tempted by simple solutions that promise quick results when you want to lose weight. Sometimes, tips circulate claiming that you can lose weight by drinking large amounts of rehydration solution. This idea is based on a misunderstanding of how the body’s fluid balance works.

Rehydration solution is designed to replace fluids and salts, for example during diarrhoea, vomiting, or heavy sweating – not for weight loss. It may temporarily affect your weight by restoring your fluid balance, but there is no scientific evidence that rehydration solution or similar products lead to long-term weight loss.

Protein is one of the body’s most important building blocks and plays a central role in maintaining and building muscle — especially when combined with strength training. But how much protein do you need per day if you want to build muscle?

‍

It’s a common claim that you need to consume protein immediately after training to build muscle. But is that really true?

Vitamins and minerals are essential nutrients that the body needs in small amounts to function properly. They affect everything from energy metabolism and immunity to muscles, blood, and bones.

The keto diet, the 5:2 method, Paleo, LCHF and intermittent fasting – these are just a few examples of popular diets that often promise solutions to your health problems and claim to be the optimal path to rapid weight loss. But how well do they actually work – and, more importantly, how sustainable are they in the long term?

In this article, we at Yazen explore how different diets work, why many people find that they’re difficult to maintain over time, and what might be a more sustainable approach to achieving your goals.

Many people have heard of the keto diet and the idea of “entering ketosis”, but what does it actually mean? In this article, we explain how the keto diet works, what the research says, and the advantages and disadvantages associated with it.

Low-carb eating (LCHF) reduces carbohydrates and replaces them with more fat and protein. For some people, this can lead to a lower energy intake, weight loss and, in some cases, improved health. In type 2 diabetes, a low-carbohydrate diet may help with blood glucose control. In this guide, you’ll learn what LCHF is, what to eat, and which risks you should be aware of before you start.
