These courses are designed for adults who want to improve their health through practical, evidence-based lifestyle changes. Whether you’re living with prediabetes, type 2 diabetes, high blood pressure, overweight or obesity—or simply want to improve your long-term health—our courses are designed to help.

All courses are created by Dr Zain Kapasi BSc (Hons) MBChB MRCGP BSLM LMCA, a UK General Practitioner with 25 years of clinical experience and additional accreditation in Lifestyle Medicine. The aim is to provide clear, practical advice that bridges the gap between medical evidence and real life.

Yes. Every course is based on current scientific evidence and recognised clinical guidance. As medical knowledge evolves, course content may be updated to reflect the latest evidence.

Yes. While some examples refer to UK healthcare, the lifestyle principles taught are relevant worldwide.

If you have diabetes, take medication that lowers your blood sugar or blood pressure, are pregnant, have significant heart disease or another serious medical condition, you should discuss any major lifestyle changes with your own healthcare professional before starting.

No. Most recommendations require little or no equipment. The focus is on improving everyday habits rather than buying expensive products.

Most people spend around 30–60 minutes per week watching the videos and completing the workbook exercises, alongside putting the ideas into practice in everyday life.

You’ll have 180 days (approximately six months) from the date of purchase to complete the course. This gives plenty of time to work through the material at your own pace and revisit lessons whenever needed during your access period.

Absolutely. Although the content is organised into weekly modules, you can progress at a speed that suits your lifestyle.

The courses work on computers, tablets and smartphones with an internet connection.

Videos are streamed through the course platform and are not generally available for download. Any downloadable resources—such as workbooks, trackers or PDFs—can be saved to your device for personal use.

While you can access lessons in the order you prefer, you’ll get the greatest benefit by completing the course as designed.

Lifestyle changes can significantly improve various health metrics. However, everyone’s health is different, so specific outcomes cannot be guaranteed.

For the Prediabetes Reset Programme, most people should arrange a repeat HbA1c blood test around 8–12 weeks after starting the programme, or as advised by their own healthcare professional.

Many people notice improvements in energy levels, sleep, fitness or weight within a few weeks. Blood test improvements often take longer and vary from person to person.

Weight is only one measure of health. Improvements in blood sugar, blood pressure, fitness, strength, sleep, energy levels and overall wellbeing are equally important.

No. The courses focus on sustainable habits rather than restrictive dieting. You’ll learn practical principles that can be adapted to your own preferences, culture and lifestyle.

No. Never stop or adjust prescribed medication without first discussing this with your healthcare professional. Lifestyle changes can sometimes reduce medication requirements, but this should always be done safely and under appropriate supervision.

There is no shortage of health information online. The challenge is knowing what to trust—and how to turn knowledge into lasting habits.

These courses combine evidence-based medicine with practical behaviour change strategies, helping you understand not only what to do, but why it works and how to make it part of everyday life. The focus isn’t on perfection or quick fixes—it’s on creating sustainable changes that can improve your health for years to come.

No. Your purchase provides access for one person only. Sharing login details or distributing course materials is not permitted. If friends or family members would like to complete the course, we’d encourage them to purchase their own access so they can benefit fully from the programme.
