🧠 What is the latest natgeo article saying about low-carb diets & heart health?
✅ The big message:
Not all low-carb diets are the same and what you replace carbs with really matters.
❤️ What researchers found
A very large long-term study (200,000 people over 30 years) showed:
👉 Some low-carb diets were linked to higher heart disease risk
👉 Others were linked to lower heart disease risk
The difference?
The type of carbs you eat and what you replace them with.
🚫 Low-carb can increase heart risk when…
People cut carbs but replace them with:
• Refined carbs (white bread, sweets, ultra-processed foods)
• Lots of saturated fat
• Low fibre intake
• Very little fruit, veg, or whole grains
In this pattern, heart disease risk increased by about 14%.
🌿 Low-carb can LOWER heart risk when…
People cut refined carbs but still eat:
• Whole grains
• Fibre-rich foods
• Fruit & vegetables
• Higher-quality carbs overall
In this case, heart disease risk actually dropped by about 15%.
🥗 The real takeaway (this is the important part)
It’s not about “low carb vs high carb.”
It’s about quality and what you eat instead of carbs matters just as much.
💬 What I tell my clients
You don’t need to fear carbs, you need to choose better ones.
Focus on:
✔ Vegetables
✔ Whole grains
✔ Legumes
✔ Fruit
✔ Fibre
✔ Healthy fats
✔ Balanced meals
Avoid:
❌ Ultra-processed carbs
❌ Extreme restriction
❌ Replacing carbs with lots of saturated fat
🧩 Simple rule to remember
Low carb doesn’t automatically mean healthy.
Balanced + high-quality food = healthy.
Sustainable nutrition is never extreme.
The goal is metabolic health, heart health, and long-term adherence, not just weight loss.
