Which is better for fat loss, HIIT or cardio?

Neither is inherently “better” – they’re different tools for different purposes. HIIT is more time-efficient and creates a greater metabolic disturbance (EPOC) ( 2 ), which can enhance fat loss. Traditional steady-state cardio can be performed for longer durations, potentially burning more total calories in a single session, and is less taxing on the body, allowing for more frequent training. A balanced program that includes both is often the most effective approach for overall health and sustainable fat loss.

Should you do an HIIT workout on an empty stomach?

Training in a fasted state may slightly increase fat oxidation during the workout, but the evidence is mixed on whether this translates to greater overall fat loss over time ( 17 ). For some people, exercising on an empty stomach can lead to dizziness or reduced performance, which compromises the intensity that’s required for a true HIIT session. It ultimately comes down to personal preference and tolerance.

What should I eat before an HIIT workout?

If you choose to eat, consume a small meal or snack rich in easily digestible carbohydrates 1-2 hours before your workout. This will top off your glycogen stores and provide the fuel that’s needed for a high-intensity session ( 18 ). A piece of fruit, a small bowl of oatmeal, or a slice of toast are good options. Avoid heavy, fatty, or high-fiber foods that can cause digestive discomfort.

Is HIIT better than a treadmill?

This question compares a training style (HIIT) with a piece of equipment (a treadmill). You can perform HIIT on a treadmill by alternating between sprints and walking/jogging. A treadmill is a tool, while HIIT is a method. The effectiveness depends on how you use the tool to implement the method.
