A warm welcome to the course! I am excited to share my passion for nutrition science with you and explore the topics related to obesity and healthy weight loss. I am hoping this will be an exciting learning journey for you!

This is a question that raises huge controversies. In this activity, we present the epidemiology of obesity and discuss the associations with non-communicable diseases. Join the discussion and share your point of view!

Have you ever explored different ways of assessing body weight status? The BMI and waist circumference are the most commonly used measures, but these are not without limitations, which we will discuss in this activity.

Dr Giles Yeo MBE who is a Principal Research Associate at MRC Metabolic Diseases Unit and a Scientific Director of the Genomics/Transcriptomics Core at the University of Cambridge will discuss the genetic context of obesity.

Is obesity determined by biology or is it all in the head? This activity will focus on explaining physiological and psychological factors associated with obesity.

This week you learnt about the prevention of obesity and overweight. In this activity, you will receive guidance on how to find reliable sources of information and access peer-reviewed articles.

Welcome to week 2! This week you will explore nutritional aspects of overweight and obesity. We will debunk some of the myths related to weight-loss and look at the obesity topic from the clinician and patient perspectives.

Have you ever wondered where the weight goes when it's lost? Or which diet is most effective? We'll address these questions in this activity and we encourage you to take part in the discussion on the evidence behind popular diets.

In this activity you will meet two experts who will help you in getting an insight into clinical and patient perspectives: Dr Kevin Deans – Service Clinical Director in Clinical Biochemistry and Ken Clare - chair of the EASO ECPO.

This week you have learnt about the nutritional aspects of weight loss. This activity will allow you to apply your knowledge with a hands-on task to calculate your own energy requirement.

Welcome to week 3! This week we focus on the non-nutritional aspects of weight loss, such as physical activity, psychological factors or bariatric surgery. Join the discussion share your views on weight-loss barriers & gateways.

This activity was created for you to get a better understanding of the role of physical activity and sleep in the weight loss process and to gain practical skills of calculating energy expenditure.

This activity discusses other routes in weight loss strategies including behavioural change, bariatric surgery and explores links with gut microbiota.

We hope you enjoyed learning about the non-nutritional aspects of weight loss. It is time to test your knowledge in the quiz provided and share your views on what promotes weight gain and what are the main barriers in weigh loss.

Welcome to week 4! This week we will focus on the most challenging part of the process - weight loss maintenance. The topics discussed include the time of eating, post-weight-loss wellness and public health perspective.

The main focus in the last few decades of nutrition research was on WHAT we need to eat (or avoid) to be healthy. The recent findings suggest that the timing of eating might be of equal importance.

This is one of the most controversial questions in the obesity topic. In this activity you will learn about public health strategies. What's your view on this - take part in the poll!

As you have learnt so far losing weight can be very difficult. Unfortunately, it can be even harder to keep the weight off. Meet the experts who will discuss weight-loss maintenance and the role of physical activity.

This week we have covered topics around the post-weight-loss challenges and discussed the latest chrono-nutrition research. It is time now, to reflect on what you have learnt so far in the peer-reviewed assignment.

Congratulations! We hope you enjoyed the course and learned a lot to take forward in your career and/or personal life.
