The Renaissance heralded a nascent interest in structured dietary practices. Thinkers like Leonardo da Vinci advocated for plant-based diets, associating them with enhanced vitality and improved health. Renaissance medical texts began to analyze the physiological effects of various foods, marking an early effort to systematize nutritional science. Concepts such as the humoral theory influenced dietary prescriptions, linking food choices to the balance of bodily fluids and temperaments. Physicians of the time began to differentiate between foods that promoted weight gain and those believed to have slimming properties, an early precursor to modern nutritional profiling.

The 19th century: the birth of modern dieting

The Banting diet

The 19th century saw the formalization of dieting with the introduction of the Banting diet. William Banting, an English undertaker, popularized this low-carbohydrate regimen in his 1863 treatise Letter on Corpulence. Under medical supervision, Banting eliminated carbohydrates such as bread and sugar, achieving notable weight loss. His dietary framework resonated widely, laying the groundwork for contemporary low-carb approaches and fostering a broader societal interest in systematic weight management. Banting’s work spurred discussions about macronutrient distribution and its impact on metabolism, influencing generations of dietary strategies.

Calorie counting

Concurrently, the scientific quantification of food intake emerged as a pivotal innovation. Wilbur Olin Atwater, an American chemist, pioneered methods for measuring the caloric content of foods, establishing a foundational paradigm for dietary planning. This shift from qualitative to quantitative evaluation enabled a more precise understanding of the relationship between energy balance and body weight. The concept of calorie counting soon gained traction, influencing both public health initiatives and individual dietary practices. Calorimetry experiments of the era provided critical insights into the energy dynamics of human metabolism.

The 20th century: scientific advances and popular diets

Weight loss medications

The 20th century marked a period of significant advancement in the pharmacological treatment of obesity. Early efforts, such as the introduction of Dinitrophenol (DNP) in the 1930s, leveraged metabolic stimulation to promote weight loss. However, the severe side effects associated with these medications underscored the need for safer alternatives. Later decades saw the development of appetite suppressants, such as amphetamine derivatives, which, despite their efficacy, posed risks of dependency and cardiovascular complications. These developments catalyzed further research into safer pharmacotherapeutic options.

Modern pharmacotherapy evolved with the advent of agents like Orlistat and, more recently, semaglutide. These medications offer improved safety profiles and efficacy, reflecting advances in understanding the hormonal and metabolic mechanisms underlying obesity.
