Fat Metabolism

Saturated fats are presented as satiating and able to reduce meal frequency and total food intake. Increased fat breakdown in adipose tissue contributes to weight loss. By about 16 hours of fasting, fat-derived fuel use becomes more active. The article says fat-based diets can support weight management and sustained energy through satiety. Regular fasting periods are associated with improved metabolic flexibility and better glucose and lipid markers. An average thin person stores roughly 77,000 calories as fat but only about 1,700 calories as glycogen — a 45:1 ratio. The article asserts that fat yields substantially more ATP per molecule than glucose. Fat release around hour 18 is described as two to three times the baseline lipolysis rate measured at 12 hours. When carbohydrate intake is low, fat type is presented as less important than total energy balance. Fat breakdown can be reduced by 80% to 90% while insulin remains elevated compared with a true fasted state. GLP-1 and GIP agonists increase lipolysis, breaking down stored fat into free fatty acids. Hormone-sensitive lipase breaks stored triglycerides into fatty acids that can be used for fuel. Burned fat is metabolized into…
