Summary
Nutritionist Tsui Chee-ka, writing on her Facebook page, is debunking a common weight loss myth as summer arrives and many Hong Kong residents ramp up their exercise routines . Many exercisers believe that visible sweating indicates successful fat burning, but Tsui explains that "fat burning" and "fat reduction" are fundamentally different physiological processes . True fat reduction requires sustained calorie deficit over time, not merely the sensation of burning calories during a workout . Her practical guide offers three actionable tips that address the root causes of weight loss plateaus.
Key Points
- "Fat burning" refers to the body's use of fatty acids for energy during moderate, sustained activities such as brisk walking, jogging, swimming, or easy cycling .
- "Fat reduction" demands two conditions: fat tissue must be broken down and enter the bloodstream, and the body must maintain a long-term calorie deficit .
- Exercise modalities better suited for actual fat reduction include HIIT jump rope, sprint intervals, spinning, and resistance training, as these preserve muscle mass and maximize total calorie expenditure .
- High-intensity training carries risks when combined with poor sleep, insufficient calories, or elevated stress, potentially causing fatigue, chronically elevated cortisol, appetite swings, and post-workout binge eating .
- Three essential factors beyond sweating are whether protein intake is sufficient, sleep quality and duration are stable, and muscle mass is maintained or increased .
Why It Matters
For Hong Kong's fitness-conscious population, this distinction between exercise-induced fat burning and genuine body fat reduction could reshape how they approach summer weight loss goals . Understanding that sustainable fat loss depends on consistent calorie deficit rather than workout intensity may help prevent the burnout and frustration that often derail long-term weight management efforts .
