Prof. Benjamin Murphy, Ph.D.The control of glucose absorption by meal sequencing is powerful because it helps control the digestive processes. Eating vegetables and proteins at the beginning of a meal activates digestive enzymes that slow down the digestion of carbohydrates. Having healthy fats before complex carbohydrates creates physical barriers in the stomach to delay sugar absorption into the bloodstream considerably.
Vegetable-First Strategy
- Fiber-rich greens form a gel matrix slowing gastric emptying rates
- Plant compounds activate digestive enzymes that regulate carb breakdown
- This creates a buffer preventing rapid glucose surges from later carbs
Protein Priority
- Amino acids stimulate GLP-1 hormone improving insulin sensitivity
- Proteins require acidic digestion delaying carbohydrate processing
- This sequencing can reduce post-meal glucose spikes by 40-50%
Fat Timing
- Healthy fats coat stomach lining slowing carbohydrate absorption
- They trigger CCK hormone promoting satiety and enzyme regulation
- This creates sustained energy release rather than sugar spikes
The inclusion of sour starters, such as vinegar or lemon, also aids in enzymatic action, as they result in the activation of pepsin for protein digestion and a retardation in the action of α-amylase on carbohydrates. This dual effect produces a useful buffer of 20 to 30 minutes. Before glucose is absorbed, even small quantities of the sour starters will have a measurable impact pharmacodynamically.
Time intervals for meals allow for complete digestion cycles to occur. Waiting 3-4 hours between meals gives insulin a chance to digest the glucose fully. Avoiding eating just before bedtime prevents glucose processing during low-sensitivity levels during night hours. Using consistent timings will train the body, allowing for metabolic expectations and optimal hormone processing.
Personalization maximizes the benefits obtained from sequencing. Constant monitoring will highlight the individual responses to varying sequences. Some individuals benefit most from vegetables taking precedence, whilst others benefit from making proteins a priority. Thus, testing the different variations of servings will help identify the optimal pattern of functioning to maintain a consistently high level of energy throughout the day.
