Carbohydrates are the body's main and preferred source of fuel, powering everything from basic cellular functions to high-intensity exercise. But how do carbs get converted into energy, specifically into the molecule called adenosine triphosphate (ATP)? The journey begins with digestion and continues through the intricate process of cellular respiration.

Every living cell requires a constant supply of energy to function, with some organisms burning thousands of their own weight in ATP daily. The two fundamental processes that help in obtaining energy from food are cellular respiration and fermentation, which break down nutrients to produce the energy currency of the cell, adenosine triphosphate (ATP).

According to the U.S. Environmental Protection Agency (EPA), a drop in temperature from 24°C to 7°C can increase vehicle fuel consumption in urban commutes by 12 to 28%. This highlights how even small environmental changes can impact what is the fuel utilization, which is the measure of how efficiently fuel is converted into useful energy or work.

According to the Cleveland Clinic, your metabolism uses energy from food constantly, even while you sleep, to keep your body functioning. This intricate metabolic process is the reason what makes food into energy, supplying every cell with the power it needs for survival and function.

The human body is only about 25% efficient at converting food energy into mechanical energy, with the rest released as heat. The intricate process of cellular metabolism explains how do we use energy from the food we eat to perform tasks, from fueling basic cellular functions to powering intense physical activity.

Did you know that your small intestine alone absorbs about 90% of the water you consume, an essential part of the process of conversion of food into nutrients? This incredible journey from meal to cellular fuel is a complex biological feat, involving multiple organs working in concert to break down food and deliver energy to every cell.

According to the Food Standards Australia New Zealand database, a raw, peeled cavendish banana contains approximately 394 kJ per 100g. In simple terms, this means that a 100g serving of banana delivers nearly 394,000 joules of energy, a figure which can vary slightly depending on ripeness and variety.

Per unit mass, fat molecules provide more than twice the energy of carbohydrates, making them an incredibly dense fuel source for the body. To harness this potent fuel, you must understand the metabolic pathways and strategic triggers that answer the question, "How do I turn fat into energy?".

The average human adult needs around 2,000 kilocalories of food energy per day to sustain normal bodily functions. This vital fuel is extracted through a complex and highly efficient biological process that explains how does the body take energy from food to power every cell and activity, from thinking to running.

One kilojoule (kJ) is equal to 1,000 joules, making it a larger and more practical unit for measuring energy in many applications. This metric unit of energy, often seen on food labels in countries like Australia, quantifies the energy people get from consuming food and drink. To understand how much is 1 kJ of energy, we can translate it into relatable, everyday terms and comparisons.
