The Science Behind Exercise & a Low-Calorie Diet
🔹 Why Exercise is Essential for Fat Loss (Not Just Weight Loss)
Most people believe that cutting calories alone is enough for weight loss, but without proper exercise, up to 25% of weight lost can come from muscle instead of fat.
✔ Preserves Lean Muscle: Strength training prevents muscle breakdown when calories are reduced.
✔ Increases Caloric Burn: HIIT and resistance training raise post-exercise calorie burn (EPOC effect).
✔ Prevents Metabolic Slowdown: Maintaining muscle keeps your metabolism high.
✔ Supports Long-Term Weight Maintenance: Regular exercise makes it easier to keep weight off permanently.
🔬 Science Insight: A study in The American Journal of Physiology found that resistance training preserves lean muscle while dieting, whereas cardio-only plans often lead to muscle loss.
📌 Quick Tip: Pairing strength training + low-impact cardio is the best combination for fat loss without muscle depletion.
Best Exercises to Pair with a Low-Calorie Diet
1️⃣ Strength Training (The Foundation of Fat Loss Without Muscle Loss)
✅ Why It’s Important:
✔ Prevents muscle loss while dieting.
✔ Burns more calories over time due to increased muscle mass.
✔ Improves strength and functional movement.
📌 Recommended Strength Training Routine (3-4x per week):
Workout Plan:
1️⃣ Squats (3 sets x 12 reps) – Works legs, glutes, and core.
2️⃣ Push-ups or Dumbbell Press (3 x 10-12 reps) – Builds upper body strength.
3️⃣ Deadlifts (3 x 8-10 reps) – Engages full body, preventing muscle loss.
4️⃣ Plank Holds (3 x 30 sec) – Core stabilization for better posture and balance.
How to Perform These Exercises (Step-by-Step)
📌 Squats:
1️⃣ Stand with feet shoulder-width apart.
2️⃣ Lower your hips as if sitting in a chair, keeping knees behind toes.
3️⃣ Push through your heels to return to standing.
📌 Push-Ups:
1️⃣ Start in a plank position, hands slightly wider than shoulders.
2️⃣ Lower your chest until your elbows reach a 90-degree angle.
3️⃣ Push back up to the starting position.
📌 Deadlifts:
1️⃣ Stand with feet hip-width apart, holding dumbbells or a barbell.
2️⃣ Hinge at the hips and lower the weights toward the ground.
3️⃣ Keep your back straight and engage your core as you return to standing.
🔬 Science Insight: Studies show that lifting weights while in a calorie deficit helps retain 85-90% of muscle mass compared to cardio-only routines.
📌 Tip: Use progressive overload (increase weight or reps over time) to maintain muscle while cutting calories.
2️⃣ High-Intensity Interval Training (HIIT) for Fat Loss
✅ Why It’s Effective:
