Introduction
The recently published House of Lords Food, Diet, and Obesity Committee Report for the 2024–25 session shines a critical light on the UK’s ongoing health challenges related to diet and obesity. The Health Survey for England 2021 published late last year showed that in the UK 68.6% of men and 59% of women are either overweight or obese.
As obesity rates continue to climb, the report calls for urgent action in improving public health through targeted policies and individualised nutritional approaches. This places the evolving field of personalised nutrition in a unique position as an integral part of our future healthcare paradigm. Personalised health and nutrition align perfectly with the Government’s strategy and emphasis on preventative and therapeutic health policies.
Cambridge Nutritional Sciences believes that personalised nutrition sits at the heart of healthcare. Understanding how food sensitivity testing and adopting personalised nutrition protocols based on the results may play a role in helping people achieve better health outcomes, manage weight more effectively and stem the obesogenic tide is a key goal for the company.
Key points from the report
The House of Lords report underscores a number of strategies for tackling obesity, including:
1. Improving dietary quality
Recommending policies to make healthier foods more accessible and affordable. Due to the struggle for many to make ends meet during the cost-of-living crisis, food choices have become dependent largely if not solely on affordability. The overall price of food and non-alcoholic beverages rose around 25% between January 2022 and January 2024. In the 10 years prior to this, overall food and non-alcoholic beverage prices rose by 9%. Consuming home prepared foods as part of a nutritious balanced diet - wider nutrition education in schools and communities as well as upskilling cooking skills so that people can confidently prepare cost effective nutritionally balanced home prepared meals for their families.
2. Personalised nutrition
Recognising that dietary interventions are not one-size-fits-all and advocating for tailored nutrition plans to support long-term health.
3. Public health initiatives
Emphasising the need for public awareness campaigns to educate individuals about healthy eating and obesity prevention. Initiatives such as wider nutrition education in schools and communities alongside basic cookery skills will enable people to confidently prepare cost-effective, nutritionally balanced home prepared meals for their family.
4. Food industry to bear the cost
Business gains taking precedence over food quality and the need to meet our dietary requirements, has led the report to conclude that the food industry must bear a major responsibility for the obesity public health emergency and shoulder a fair share of the cost through new taxation and regulation.
5. Research
More scientific research independent of industry on food, diet and health, and on food and health policy, and to ensure that there are effective funding mechanisms in place for such research to be undertaken.
These recommendations align well with a broader perspective on health, where individual variation, such as food sensitivities, can be considered in crafting effective, personalised dietary plans.
Food sensitivity testing: a valuable tool in personalised nutrition
Food sensitivity testing, i.e. IgG-mediated testing, offers insight into how an individual’s immune system may react to certain foods over time. Unlike immediate, life-threatening allergies, food sensitivities can lead to delayed and often subtle symptoms, such as bloating, fatigue, or mild inflammation. While these reactions aren’t necessarily harmful on their own, they can affect a person’s overall wellbeing, and in some cases, may contribute to challenges with weight management.
IgG-mediated food sensitivity testing helps individuals and practitioners identify foods that might be best limited or removed temporarily to assess improvement in symptoms. By reducing or eliminating these “trigger” foods, people may experience more stable energy levels, fewer cravings, and improved digestive health—all factors that support adherence to a healthier diet.
Exploring the link between food sensitivities and obesity
Although food sensitivities alone are not a primary cause of obesity, research and clinical observations suggest they can influence dietary habits. Food sensitivities may lead to chronic low-grade inflammation, which is associated with various metabolic issues. Individuals dealing with bloating, fatigue, or discomfort after eating may struggle to stick to a balanced diet or may experience increased cravings for specific foods, especially those high in sugar or carbohydrates.
Identifying and managing food sensitivities could help people maintain more consistent energy levels, reduce cravings, and support healthier eating habits. In clinical practice, some patients who address their food sensitivities report improved adherence to weight management plans and an overall improvement in wellbeing.
Practical applications for clinicians and patients
For clinicians, food sensitivity testing can be a useful addition to the tools available for guiding patients in personalised nutrition. When test results are carefully interpreted, they can help design a plan that minimises reactive foods while ensuring a balanced intake of nutrients. Patients are often encouraged to keep a food and symptom diary as they adjust their diet, allowing them to track improvements in symptoms, including mood, sleep and energy levels, and adherence to their health goals.
It is essential to emphasise that food sensitivity testing is not a stand-alone solution for obesity; rather, it works best when combined with a comprehensive approach that includes a balanced diet, regular exercise, and mental health support. With this holistic approach, clinicians can offer their patients a more personalised strategy for weight management.

Policy implications and future directions
As we consider ways to incorporate the House of Lords report’s recommendations into everyday healthcare, food sensitivity testing presents an area for potential inclusion as part of a personalised nutrition approach. Future policies could explore how food sensitivity testing might fit within personalised nutrition strategies, especially for individuals facing metabolic challenges related to obesity. With more research and evidence, food sensitivity testing could become a recognised component of national dietary guidelines, supporting people’s journeys to healthier lives.
Conclusion
The House of Lords Food, Diet, and Obesity Committee Report is a call to action, aiming to improve public health and tackle the obesity crisis with innovative, evidence-based approaches. Early and decisive action in a child’s life will reduce the risk of obesity and diet-related disease.
By recognising the role of individualised nutrition and considering food sensitivity testing as a complement to dietary guidance, healthcare practitioners and policymakers can work together to promote better health for all.
The journey to optimal health is unique for everyone, and food sensitivity testing could be an important piece of the puzzle, helping people make informed choices and achieve lasting wellbeing.
