"It should be remembered that amino acids, especially in eggs, stimulate insulin secretion, and that this can cause hypoglycemia, which in turn causes cortisol secretion.
Leucine is stimulating muscle turn over (new ones) when exceeding 2.5-3 g per take. It won't stimulate insulin too much if you eat some carbs at the same time. Never eat only protein without some carbs. 20 g is enough, from a tomato or an apple at the beginning of the meal.

The Leucine Threshold and mTORC1 Activation
• Fact: Consuming 2.5 to 3 grams of leucine per meal is the established threshold required to maximize muscle protein synthesis.
• Mechanism: Leucine acts as the primary nutritional signal to activate mTORC1 (mammalian target of rapamycin complex 1), which initiates cellular translation and muscle tissue turnover.
• Application: Whole proteins like eggs have a high concentration of highly bioavailable leucine, making them highly effective at reaching this trigger.
Protein-Induced Insulin Secretion and Hypoglycemia
• Fact: Amino acids (particularly arginine, lysine, and leucine) directly stimulate pancreatic beta cells to secrete insulin, independent of carbohydrate intake.
• The Risk: In the absence of dietary carbohydrates (e.g., eating only eggs), this insulin secretion can cause blood glucose levels to drop.
• The Counter-Mechanism: In a standard physiological state, the pancreas simultaneously secretes glucagon to stimulate hepatic glucose production (glycogenolysis) to keep blood sugar stable. However, if insulin secretion is highly sensitive or if hepatic glycogen stores are depleted, a drop in blood sugar can occur, prompting an emergency release of cortisol to restore homeostasis.
The Role of Pre-Meal Carbohydrates (20g Context)
• Fact: Introducing 20 grams of carbohydrates (such as from an apple or tomato) at the beginning of the meal alters the metabolic baseline before the protein is processed.
• Mechanism: The incoming exogenous glucose matches the insulin response. The insulin stimulated by the amino acids is no longer acting "in a vacuum" on existing blood sugar; instead, it has immediate dietary glucose to shuttle into cells.
• Outcome: This direct glucose supply buffers the system, ensuring that blood glucose concentrations do not fall below fasting levels, thereby preventing the hypoglycemic trigger that would otherwise necessitate a cortisol spike.
