Keerthy Suresh Weight Loss Journey With Cardio Only: The Truth Behind Her Transformation

South Indian actress Keerthy Suresh, celebrated for her talent and grace, shocked fans when she revealed she lost 9 kilos through a cardio-only approach — without any fad diets, weight-loss pills, or extreme restrictions. While the results were impressive, Keerthy has since shared that relying solely on cardio came with hidden drawbacks.

The Beginning: Keerthy’s Cardio-Only Phase

In 2019, Keerthy felt she needed a physical transformation. “I was a little built… not fat, but I wanted to slim down,” she shared in an interview. She committed to intense cardio sessions — running, cycling, and high-intensity workouts — but skipped strength training completely.

This approach led to rapid weight loss. “My face looked sculpted, I was looking very thin,” Keerthy recalled. But she later realised her muscle mass had dropped significantly. “When you do a lot of cardio without strength training, you lose muscle,” she said.

The Problem With Cardio Alone

Cardio exercises such as running, swimming, and skipping are excellent for burning calories and improving heart health. However, overdoing cardio without incorporating strength training can result in:

• Muscle loss: Lean muscle mass breaks down when strength exercises are absent.
• Slower metabolism: Less muscle means your body burns fewer calories at rest.
• Skinny-fat appearance: Weight is lost, but body definition is lacking.
• Lower strength and stamina: Day-to-day functional strength decreases.

Why Muscle Matters

Muscle tissue is metabolically active — it burns calories even when you’re not working out. Losing muscle through excessive cardio can make future fat loss harder. It also impacts posture, bone health, and overall body strength.

Cardio vs Strength Training: The Balance

Experts recommend combining both cardio and resistance training for optimal results. Here’s why:

• Cardio benefits: Improves cardiovascular health, burns fat, increases endurance.
• Strength training benefits: Builds and maintains muscle mass, boosts metabolism, tones the body.
• Best approach: 150–300 minutes of cardio weekly + 2–3 days of weight training.

Keerthy Suresh’s New Fitness Strategy

Learning from her earlier approach, Keerthy now focuses on:

• Integrating strength training to maintain muscle mass.
• Keeping cardio sessions moderate for heart health and fat burn.
• Eating balanced, whole-food meals instead of crash diets.
• Prioritising sleep, hydration, and recovery.

Common Weight Loss Mistakes to Avoid

• Doing only cardio without resistance work.
• Relying on extreme diets that cut out entire food groups.
• Overtraining without giving the body time to recover.
• Ignoring protein intake, which is essential for muscle repair.

Expert Tips for Sustainable Weight Loss

• Combine cardio and strength training for a balanced body composition.
• Follow a protein-rich, nutrient-dense diet.
• Track your progress through measurements, not just weight.
• Allow at least 1–2 rest days weekly to prevent burnout.
• Stay consistent rather than chasing quick fixes.
