You’ve probably heard this before:
“Drink cold water — it helps burn more calories!”
But is it just a myth, or is there real science behind it?
Let’s break it down.
đź’§ The Theory: Thermogenesis
When you drink cold water (especially between 4–10°C), your body needs to heat it up to your core temperature(~37°C).
To do this, your body uses energy — a process called thermogenesis.
Yes, this burns calories.
But… how many exactly?
🔥 How Many Calories Does Cold Water Burn?
According to a study published in the Journal of Clinical Endocrinology and Metabolism, drinking 500 ml (about 2 cups) of ice-cold water:
- Temporarily increases metabolic rate by up to 30%
- Burns around 25 extra calories
That’s about the same as chewing gum for an hour… or walking for 5 minutes.
⚖️ So… Can It Help With Weight Loss?
Technically, yes — but not significantly.
If you drink 2 liters of ice water per day, that’s about 100 extra calories burned.
It adds up over time, but it’s not a weight loss strategy by itself.
👉 It’s like a bonus — not the main event.
đź’ˇ When Cold Water Can Be Helpful
Even though the calorie burn is small, cold water still has other benefits:
- Improves alertness and mental clarity
- Reduces core temperature after workouts
- May suppress appetite slightly
- Keeps you hydrated, which indirectly helps metabolism
And for those trying to gain weight:
👉 Stick with room-temperature water — cold water might reduce your appetite.
🧠Final Thought
Cold water isn’t a magic fat-burner.
But staying well-hydrated is crucial for metabolism, digestion, energy, and even performance in the gym.
If you enjoy cold water — go for it.
Just remember: muscles, meals, and movement are still the main keys to changing your body.
âś… Quick Summary:
- ❄️ Cold water burns a small number of calories via thermogenesis
- 🔥 500 ml may burn ~25 calories
- ⚖️ It won’t replace workouts or diet, but every bit helps
- đź’§ Hydration = metabolism support

🧊 Bottom line: Drink your water — cold or not — and keep showing up daily.
That’s how change happens. 💪
