Blood glucose stability, avoiding the sharp spikes and subsequent crashes that follow high-glycaemic meals, is fundamental to sustained energy, body composition, hunger regulation, and long-term metabolic health. Poor blood sugar control drives insulin resistance, increases visceral fat storage, raises cardiovascular risk, and accelerates biological ageing. Managing it through food choices is both effective and sustainable.
The Meal Composition Hierarchy
- Protein first at every meal: protein stimulates GLP-1, PYY, and CCK, the satiety hormones, and produces a minimal glycaemic response
- Non-starchy vegetables: fibre slows gastric emptying, reduces the rate of glucose absorption, and feeds the gut microbiome
- Fat alongside carbohydrates: reduces the glycaemic index of the meal by slowing gastric emptying
- Carbohydrates last in the eating sequence: research has shown that eating carbohydrates after protein and fat reduces postprandial glucose response by up to 37 percent compared to eating carbohydrates first
The Foods to Limit
- Refined carbohydrates including white bread, white rice, and pasta in large portions
- Added sugars in processed foods, particularly liquid calories including fruit juice, energy drinks, and sweetened beverages
- Breakfast cereals including those marketed as healthy, which typically have a high glycaemic load
- Alcohol, which causes reactive hypoglycaemia several hours after consumption
Timing and Movement
A 10-minute walk after eating reduces postprandial blood glucose by 20 to 30 percent by driving muscle glucose uptake independently of insulin. This single behaviour change has a meaningful impact on glycaemic control. Evening meals that are high in carbohydrates produce the worst glycaemic responses because insulin sensitivity naturally decreases in the evening. Front-loading carbohydrate intake earlier in the day is a practical strategy for improving overall daily glucose management.
