Continuous glucose monitors reveal how differently individuals respond to carbohydrates. We classify these responses using Glucotype, which reflects innate carbohydrate tolerance, and Current Glucose Profile (CGP), which shows a person’s present metabolic state. Combined with visceral fat grading, this system helps identify metabolic risk and guide personalised dietary or medical interventions.
Prediabetes should be viewed as an active cardiometabolic disease stage rather than a passive risk marker. Cardiovascular injury begins before overt diabetes, creating a critical window for intervention. Lifestyle therapy remains fundamental, while agents such as metformin, GLP-1 receptor agonists, dual incretin therapies, and SGLT2 inhibitors may help modify long-term cardiovascular risk.
Some small studies show lower T3 inside fat tissue in people with obesity. This doesn’t mean systemic hypothyroidism — it simply suggests inflammation may reduce local T3 activation. Raised visceral fat quietly disrupts thyroid chemistry, increasing reverse T3 and lowering active T3 inside tissues.
At Surrey Cardiovascular Clinic, we have seen a pattern: some people whose blood sugar (HbA₁c) is technically “normal” are quietly drifting towards diabetes. Their blood tests look fine — but their day-to-day glucose readings tell another story.
The keto and Atkins diets have profound effects on hepatic lipid metabolism, and hence on LDL cholesterol handling. Let’s unpack this carefully through the lens of the endogenous cholesterol pathway.
For patients with CKD 3b, a high-protein diet may accelerate renal decline and should be avoided. However, metabolic improvement via a moderate low-carbohydrate diet with controlled protein intake (~0.8 g/kg/day) and unsaturated fats is both feasible and safe when guided appropriately. Creatinine changes should be interpreted carefully in the context of diet, and dietary interventions should be closely monitored.
When most people think of a cooked breakfast, they picture something indulgent — bacon, eggs, toast, maybe pancakes or juice. But my version of a cooked breakfast is carefully designed to help reduce visceral fat (VAT), improve satiety, and support stable energy levels throughout the morning. Here's how I do it — and why it works.
An article by Dr Edward Leatham, Consultant Cardiologist © 2026 E.Leatham Introduction For decades, health advice has emphasised “low-fat” as the healthy option. Supermarket shelves are stacked with skimmed and semi-skimmed milk, marketed as the heart-friendly choice. Yet, in recent years, our […]
Dietary fats have been wrongly maligned for much of modern nutritional history. But as the science evolves, it's clear that fat – far from being harmful – is a vital macronutrient that supports energy metabolism, hormonal health, brain and heart function, and even weight control.Rather than fearing fat, we should focus on:Avoiding refined carbohydrates and ultra-processed foods. Prioritising whole food sources of fat, including nuts, seeds, dairy, eggs, fish, and healthy oils. Understanding individual needs, especially in those with insulin resistance or carbohydrate sensitivity. Viewing nutrition in context, rather than isolating single nutrients as heroes or villains.The time has come to move beyond fat-phobia and embrace a more nuanced, evidence-based approach to eating. In a balanced, whole-food diet, fat is not the problem — it’s part of the solution.
Recent scientific discoveries have aligned much like planets, leading to an inescapable conclusion among many physicians that glucose metabolism may be even more important than LDL cholesterol in the genesis of many modern diseases.
Continuous glucose monitoring offers a valuable tool for anyone concerned with their long-term health, especially those with a family history of diabetes or other cardiovascular risk factors. Whether through self-monitoring or professional analysis such as our metabolic health assessment, CGMs can provide actionable insights that help individuals manage their glucose levels more effectively, ultimately contributing to a healthier, longer life. By understanding and managing your glucotype, optimising your diet and exercise, and taking steps to prevent prediabetes and diabetes, you can potentially avoid serious health conditions in the future.
This blog explores how individuals can conduct their own experiments to maintain a steady blood glucose and avoid potentially unhealthy glucose spikes above 7.8 mmol/L (140 mg/dL).
