Is the Sanfu period suitable for weight loss?

　　The Dog Days of Summer (Sanfu period) are generally suitable for scientifically guided weight loss, as the body’s metabolic rate is naturally elevated and fat-burning efficiency is relatively higher during this time. However, weight loss should follow the principle of gentle fat reduction—extreme calorie restriction and high-intensity outdoor exercise under intense sun exposure must be avoided. If persistent fatigue, dizziness, palpitations, or metabolic disturbances occur during weight loss, prompt consultation with a specialist in a professional medical department is advised.

　　During the Dog Days, ambient temperatures are high, leading to a natural increase in basal metabolic rate and higher energy expenditure compared to temperate seasons. This facilitates more rapid burning of excess calories and stored fat. Increased sweating in summer accelerates water and sodium metabolism, effectively alleviating edema caused by fluid and sodium retention and resulting in a firmer, more toned physique. Additionally, hot weather naturally suppresses appetite for high-calorie, high-fat foods, reducing the likelihood of binge eating. When combined appropriately with physical activity and dietary regulation, this environment supports steady improvement in fat-loss efficiency and helps establish healthy, sustainable weight-management habits.

　　Weight loss during the Dog Days carries certain contraindications and risks; pursuing rapid weight loss without guidance may impair bodily functions. Under high-temperature conditions, the body expends considerable energy; excessive dietary restriction can lead to inadequate nutrient intake, causing symptoms such as physical weakness, fatigue, and reduced immunity. Prolonged vigorous outdoor exercise significantly increases the risk of heatstroke, dehydration, and other adverse effects, potentially compromising cardiovascular function. Moreover, gastrointestinal and spleen-stomach functions tend to be relatively weaker during this period; inappropriate dietary control may further burden these organs and disrupt metabolic balance. Therefore, fat loss should proceed gradually, relying on moderate physical activity and light, balanced meals to achieve healthy, sustainable weight reduction.

　　In daily life, adopt a pattern of eating smaller, more frequent meals; engage in gentle aerobic exercise both morning and evening; and maintain adequate hydration to replenish fluids lost through metabolic activity. Consistent sleep-wake cycles help stabilize endocrine function, while gradual, progressive adjustments to body fat percentage support long-term maintenance of a healthy, well-proportioned physique.
