Meal replacements are sometimes used as a tool for weight loss and weight management. There are lots of different products to choose from, designed to replace one or more meals in a nutritionally balanced way. For some people, they can be a practical support and make it easier to keep track of energy intake, but they are not right for everyone. In this article, we look at the pros and cons of using meal replacements for weight loss.

Protein powder can be a handy support when you’re losing weight, especially if it feels hard to get enough protein once you’re eating fewer calories. For some people, it’s a convenient option that makes meal planning a bit easier. That said, protein powder isn’t essential and it doesn’t replace a nutritious, varied diet. In this article, we look at when protein powder can be helpful and how it might support weight loss.

Protein can be a helpful support if you’re aiming to lose weight in a sustainable way. It can help you feel fuller for longer and support your body in maintaining muscle mass when you’re eating fewer calories. But how much protein do you actually need when trying to lose weight, what are the benefits and possible risks, and how can you increase your protein intake in everyday life? In this article, we go through everything you need to know about protein and weight loss.

The answer is both yes and no. It’s not smoothies themselves that lead to weight loss, no matter how “healthy” they seem. Losing weight always comes down to being in a calorie deficit.

That said, smoothies can still have a place in a balanced diet. They can be a handy option when you’re short on time or don’t feel very hungry, and they’re also an easy way to get more protein, veg, fruit and berries into your day.

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.

Weight loss supplements are often marketed as quick, easy fixes, with promises of reduced appetite, more energy and increased fat burning. In reality, the effect is usually modest. In some cases they can be a small addition to a healthy diet, but they do not replace what really affects weight and health in the long term: everyday habits, energy balance and behaviour.

‍

Fasting is often used as a tool for weight loss and better health. There are several types of time-restricted eating, also called intermittent fasting. The most common are 5:2, 16:8, Eat Stop Eat, and alternate-day fasting. For some people, fasting can make mealtimes feel more structured and help reduce overall energy intake. But it is not right for everyone, and for some it can come with risks and limitations that are important to know about.

‍

The word “keto” comes from ketones – substances the body produces when it mainly uses fat for energy instead of glucose. When ketone levels rise in the blood, this is called ketosis. It’s a natural state the body can enter during things like fasting or when you eat very few carbohydrates. But when can ketosis be harmful, and what are the risks of a ketogenic diet? In this article, we look at what the research actually says.

‍

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.
