Best Workouts for Fat Loss (Evidence-Based Ranking)

By IndexBody Editorial·IndexBody Editorial

Counterintuitive finding: The best workout for fat loss is not the one that burns the most calories during the session. It's the one that preserves muscle, raises your metabolic rate long-term, and is sustainable enough to do consistently.

Why Resistance Training Wins for Fat Loss

Research consistently shows that resistance training produces superior body composition outcomes compared to cardio alone during a caloric deficit — even when cardio burns more calories per session. The reason: resistance training preserves lean muscle mass, which maintains metabolic rate and improves the ratio of fat to muscle lost.

A meta-analysis of 58 studies found that resistance training combined with a caloric deficit lost 28% more fat mass than calorie restriction alone, despite burning fewer calories during exercise sessions.

The Optimal Fat Loss Programme

Resistance training 3–4×/week: Compound movements — squat, deadlift, bench press, row, overhead press. 3–4 sets of 8–12 reps. This is non-negotiable for muscle preservation.

HIIT 1–2×/week: 20–30 minute sessions of high-effort intervals. Effective for additional calorie burn with minimal time investment and a meaningful EPOC (excess post-exercise oxygen consumption) afterburn effect.

Daily walking: 8,000–10,000 steps per day. Do not underestimate this. Walking does not feel like exercise but it significantly increases NEAT, can account for 200–400 extra calories burned per day, and has no meaningful recovery cost.

What About HIIT vs LISS Cardio?

HIIT (High-Intensity Interval Training) burns more calories per minute than LISS (Low-Intensity Steady State) and produces a greater afterburn effect. However, HIIT has a higher recovery cost, which can impair performance in resistance training sessions. For most people, 1–2 HIIT sessions per week supplemented with daily walking is the optimal balance.

Frequently Asked Questions

What type of exercise is best for fat loss?
+
For body composition, resistance training combined with a caloric deficit produces the best results — more fat lost and more muscle preserved compared to cardio alone. Complement with 1–2 HIIT sessions and daily walking for an optimal fat loss programme.
How many calories does lifting weights burn?
+
A 75kg person burns approximately 200–350 kcal during a 45-minute resistance training session. However, the lasting metabolic benefit — elevated BMR from increased muscle mass — is more significant long-term than the calories burned during the session.
