What will you study on this Postgraduate Diploma in Obesity & Weight Management?

The Postgraduate Diploma in Obesity and Weight Management provides a broad understanding of obesity medicine, beginning with the biological mechanisms involved in body weight and energy regulation. You’ll examine adipose tissue and adipocyte biology, body composition, energy intake and expenditure, and the neuroendocrine regulation of appetite, considering how different organs and physiological systems contribute to energy balance.

You’ll then consider obesity as a chronic disease at both individual and population level. This includes obesity epidemiology and the global burden of obesity, alongside metabolic syndrome and obesity-related conditions, including cardiovascular disease, type 2 diabetes, and cancer. You’ll also examine wider determinants of weight gain and obesity across the life course and consider approaches to assessment and staging.

The programme explores the complexity of obesity further through genetic, medical, and environmental factors. You’ll examine genetics and inherited conditions, epigenetics and gene-environment interactions, endocrine causes of weight gain, medicines associated with weight gain, and the developing evidence around the gut microbiota.

The second half of the programme focuses on personalised weight management. You’ll critically examine evidence for nutrition and physical activity interventions alongside approaches to behaviour change, including motivational interviewing and cognitive behavioural therapy-informed approaches. You’ll also consider the importance of compassionate communication, weight stigma, and multidisciplinary working when supporting people living with obesity.

Contemporary medical management forms a substantial part of the curriculum. You’ll examine obesity pharmacotherapy, including the mechanisms, evidence, efficacy, and adverse effects associated with medical treatments, alongside GLP-1 receptor agonists and emerging obesity therapies. Pharmacovigilance and the evaluation of past, current, and emerging treatments are considered as part of an evidence-based approach to obesity medicine.

You’ll also study bariatric and metabolic surgery, including different surgical approaches, patient selection, risks, and the role of the multidisciplinary team before and after surgery. This allows you to consider nutrition, behavioural, medical, and surgical approaches within the wider context of personalised weight management rather than as isolated interventions.

During the programme, you’ll study:

  • Adipose Tissue and Energy Balance – Examine adipose tissue and adipocyte biology, fat distribution, appetite regulation, energy balance, and body composition, including the interaction between adipose tissue, the brain, gastrointestinal tract, and other organs involved in the regulation of food intake and energy expenditure.
  • Obesity Epidemiology and Population Health – Consider obesity as a chronic disease and examine its epidemiology, global burden, and relationship with population health. You’ll explore assessment and staging alongside obesity-related comorbidities, wider determinants of obesity, and approaches to prevention.
  • Disease, Genetics and Environmental Factors – Examine genetic, epigenetic, medical, and environmental factors associated with weight gain and obesity, including inherited conditions, gene-environment interactions, endocrine disorders, medicines associated with weight gain, and the gut microbiota.
  • Personalised Weight Management 1: Nutrition, Physical Activity and Behavioural Interventions – Critically examine nutritional and physical activity approaches alongside behaviour change strategies, including motivational interviewing and cognitive behavioural therapy-informed approaches, within personalised and multidisciplinary weight management.
  • Personalised Weight Management 2: Medical Treatments and Emerging Therapies – Examine obesity pharmacotherapy, including mechanisms of action, evidence, efficacy, and adverse effects, alongside GLP-1 receptor agonists, emerging obesity therapies, and the role of pharmacovigilance.
  • Personalised Weight Management 3: Surgical Interventions – Examine bariatric and metabolic surgery, including surgical approaches, patient selection, short- and long-term risks, multidisciplinary pre- and post-operative care, and the health economics of surgical and medical interventions.

Together, the six modules provide a structured progression from the biological and population-level drivers of obesity through to personalised behavioural, nutritional, medical, and surgical approaches to weight management, with evidence appraisal and multidisciplinary care considered throughout.

As each Medical Council has their own rules/regulations with regard to Postgraduate study we recommend that you contact your local Medical Council with regard to recognition.

Upon completion of the course the University would invite you to a graduation ceremony and provide your certificate which makes no reference to the fact that the course was studied online and is therefore typically recognised the same as any other UK University qualification.

Rest assured, the overall Postgraduate Diploma carries a total of 1,200 CPD points, with the MSc an additional 600 CPD points, and all official certifications are issued directly by the University.

When you study one of our programmes you may be surprised to find that there are no lectures or seminars. Your learning will be self-directed meaning that rather than being told information you find it for yourself (with tutor guidance and support). We do this via a series of clinically rich scenarios which your tutor will post on our academic forum which you and your classmates will research, respond to and discuss.

You will be assessed through the Academic Forum, Reflective Journal and Assignments. Learning will be carried out using our online learning platform: Moodle.

You can study whenever and wherever you want - our programmes are totally flexible to fit around your other work and life commitments.

The course is specifically designed so that part of your study is the application of theory to practice in your day job.

We typically suggest that students aim to log into the Moodle platform daily. We recommend a "little and often" approach for reading, reflection and/or posting. High achieving students will typically spend 1-2 hours dedicated to their studies a day; 10 hours per week is sufficient time to spend on the platform.

Those who cannot dedicate more time than once/twice per week may struggle with the demands of this postgraduate programme.

Yes, everything is done entirely online through our learning platform, Moodle. You do not need to attend the University.

Assessment Methods

This programme emphasises learning through active participation in case-based discussions, reflection, and real-life scenarios. Students engage with clinical cases that mirror everyday practice, fostering problem-solving and evidence-based application from the very beginning.

Across the modules, assessments are integrated with learning. Each week, you will work through two to three clinical cases, discussing and reflecting on them with peers under the guidance of an expert tutor. These discussions form the core of your learning and are also the basis for your assessments.

Our innovative teaching methods are designed to help you translate this learning into real-world clinical practice. You'll need to regularly log in to participate in discussions, ideally on a daily basis, and commit approximately two hours per day to your studies. Our dedicated Student Support Team is available to assist with any challenges you may encounter, from navigating our online platform to managing deadlines.

How Foundational Knowledge is Developed

The programme is structured so that foundational knowledge is introduced through carefully designed clinical cases. Each case is crafted to highlight essential concepts and progressively deepen your understanding as you apply critical thinking and evidence-based analysis. This hands-on approach ensures that you are not only acquiring theoretical knowledge but also learning how to apply it in a practical, clinical setting.

This programme is suited for professionals who thrive in an online, discussion-based learning environment. Please note that this course focuses on interactive, applied learning through peer collaboration and case discussions. You will be fully supported, encouraged and led through the programme to success and graduation!

  • Every week students are presented with two/three clinical case-based scenarios that are reflective of every day clinical practice and research.
  • Tutors will post a number of questions and prompts to aid students in a formal discussion of each case.
  • These discussions are facilitated throughout by your tutor and are then assessed at the end of every module.

The reflective journal is used by students throughout each module to monitor personal progress. This is guided by weekly feedback from your tutor and is graded at the end of every module. The journal typically includes the following:

  • Initial expectations and reasons for taking the course.
  • Module and/or personal learning objectives.
  • Description of events, issues and learning points within current personal practice.
  • Change in every day practice due to knowledge gained on each module.
  • A description of what has been learned during the module.

For this assessment, students will work on a group assignment and/or an individual assignment.

  • Group assignments are designed to hone skills in the multidisciplinary, holistic approach to modern treatments and patient management by requiring group participation in a single piece of work.
  • Individual assignments are designed to hone skills in academic career progression through such tasks as reviewing papers, developing scientific posters or abstracts, peer-reviewing, social media activities, patient information leaflets and essays.
  • Students are provided with case-based problems in the form of a one-hour timed examination.
  • The exam consists of 30 'Single Best Answer' questions.
  • Students are required to complete the exam online within the set time.
