régimes

Régime (plural régimes) is a term used in French and English to describe a system or plan that governs behavior in a domain. In political science, a regime refers to the set of political institutions, norms, and practices that structure government and public life. In nutrition and health, a regimen or diet is a planned series of meals and supplements intended to achieve health, weight management, or performance.

Political regimes vary in form and legitimacy. Common classifications distinguish democratic or liberal regimes, constitutional regimes, authoritarian regimes, totalitarian regimes, and hybrid or illiberal regimes. Key features include the source of authority, rule of law, civil and political rights, and the degree of political participation. Regime change can occur through elections, reforms, coups, revolutions, or external pressure. In international relations, states may adhere to international regimes—sets of rules and norms governing specific activities, such as arms control or trade.

Dietary regimens range from weight-loss programs to medical diets for chronic conditions. They are defined by nutrient composition, energy intake, and timing. Examples include calorie-restricted regimens, Mediterranean, low-carbohydrate, high-protein, vegan, and DASH diets. Effectiveness and safety depend on individual factors, adherence, and supervision; long-term success often requires sustainable changes and professional guidance. Criticisms include variability in evidence, potential nutrient deficiencies, and the challenge of maintaining beyond initial phases.
