How Physical Activity Shapes Metabolic Function
Metabolism is often discussed as if it operates in the background, separate from daily movement. In practice, physical activity is one of the clearest signals the body receives about how...

The Role of Hormones in Metabolism
Metabolism is not governed by nutrients alone. Hormones act as chemical messengers that tell tissues when to store energy, when to release it, and how to respond to feeding, fasting,...

Why Metabolism Slows With Age
People often talk about metabolism “slowing down” with age as if it were one single process. In reality, age-related metabolic change usually reflects several shifts happening together, including changes in...

How Energy Balance Is Regulated
Energy balance refers to the relationship between energy entering the body and energy being used, stored, or released. That sounds simple at first, but the body does not manage energy...

What Is Insulin Sensitivity?
Insulin sensitivity describes how strongly cells respond to insulin’s signal. When that signal is received efficiently, tissues such as muscle, liver, and fat can manage circulating glucose in a more...

How the Body Switches Between Fuel Sources
The body does not run on a single fuel all day. It moves between carbohydrate, fat, and, in some situations, amino acid use depending on whether a person has recently...
