The concept of measuring energy in food dates back to the 18th century, with initial experiments linking respiration to combustion. The journey to understand how did humans come up with calories involves a surprising cast of scientists and engineers, and was not a straightforward process, evolving significantly over centuries of scientific inquiry.

In the late 19th century, a Wesleyan University chemist named Wilbur Olin Atwater pioneered the scientific measurement of food energy, a concept that would later evolve into modern calorie counting. His work laid the foundation for the practice, which was then popularized for the masses by early 20th-century author Lulu Hunt Peters.

The modern unit of a food calorie, or kilocalorie, was originally a unit of heat used for steam engines in the 19th century. The journey of this physics term into a household health metric reveals the surprising story of where did calorie counting come from and how it shaped dieting for over a century.

In 1770, French chemist Antoine Lavoisier discovered the process of metabolism, a groundbreaking achievement that led many to consider him the man who is known as the father of nutrition science. He was the first to explain how the body uses oxygen and food to produce energy.

A sample of food is burned in an insulated, oxygen-filled chamber to determine its gross energy content. This simple yet profound technique was a crucial step in how scientists figure out calories, a journey that revolutionized our understanding of food and energy.

The idea of quantifying food energy emerged in the 18th century, but its standardized use in nutrition took decades of scientific refinement. Discover how scientists, starting with pioneering chemists, figured out how were calories in food discovered and applied to everyday life.

While there isn't one singular 'inventor of nutrition,' French chemist Antoine Lavoisier is widely regarded as the 'father of nutrition and chemistry'. His groundbreaking work in the 1770s laid the foundation for modern nutritional science by discovering metabolism and the chemical processes by which the body consumes food and oxygen. However, a long line of researchers and discoveries over centuries contributed to our comprehensive understanding of nutrition.

The calorie, a unit we associate with diet and exercise, was originally a measurement of heat for steam engines. Before it landed on our food labels, the concept of quantifying the energy in food underwent a fascinating and complex transformation, with scientists figuring out the calorie through burning food and measuring human heat output.

In 1894, the U.S. Department of Agriculture published its first formal dietary recommendations, providing a foundational answer to the question: **What year was the first food guide created?** These early guidelines, spearheaded by chemist Wilbur Olin Atwater, predate the visual pyramids and plates many people are familiar with today.

While dietary wisdom existed in ancient civilizations, modern nutrition science is a relatively young field, truly beginning with quantitative chemical analysis in the 18th century. So, **who is the father of nutrition**? The title is most often attributed to the French chemist Antoine Lavoisier, whose groundbreaking work in metabolism laid the essential groundwork for the field.
