Fasting

A relative ranking of how quickly carbohydrates increase blood glucose levels. Lower glycemic index carbs provide sustained, non-spiking energy.

A planned temporary increase in caloric intake (predominantly carbohydrates) to restore leptin, fill glycogen, and kickstart metabolic rate.

An eating pattern aligned to the body's 24-hour circadian clock, concentrating caloric intake during daylight hours when insulin sensitivity and digestive enzyme output peak.

A measure of how effectively a food suppresses hunger relative to its caloric content. High-satiety foods like eggs reduce total energy intake, aiding body composition goals.
