What is considered one of the most effective methods for weight reduction?

Regular physical activity is considered one of the most effective methods for weight reduction because it not only burns calories but also promotes overall health and well-being. Engaging in consistent exercise increases metabolism and helps preserve lean muscle mass while losing weight, which is crucial since muscle tissue burns more calories at rest compared to fat tissue. Furthermore, regular physical activity contributes to improved cardiovascular health, better mood, and enhanced energy levels, making it easier to maintain healthy lifestyle changes long-term.

In contrast, limiting total energy intake to a very low level, such as 800 kcal per day, is generally not sustainable or healthy for most individuals and can lead to nutritional deficiencies. Similarly, reducing fat intake to extremely low levels, like under 15% of energy, may not provide essential fatty acids necessary for proper body function. While reducing trans fat consumption is important for health, especially concerning heart disease, it does not directly correlate with effective weight loss when considered in isolation from physical activity. Thus, a lifestyle incorporating regular physical activity aligns with evidence-based approaches for effective and sustainable weight management.
