For many Nigerians in the UK, fasting isn’t just about weight loss — it can be part of religious observance, health goals, or lifestyle changes. But did you know fasting can significantly affect your blood sugar levels? While it can have benefits, it also comes with risks — especially if you have certain medical conditions.
🩸 How Fasting Affects Your Blood Sugar
When you fast, your blood sugar and insulin levels drop. This signals your pancreas to release a hormone called glucagon, which tells your liver to break down stored sugar (glycogen) for energy.
As fasting continues:
- Your body starts burning fat for fuel
- Ketones are produced — a powerful energy source for your brain and muscles
- You may feel more mentally alert and less hungry (thanks to ketones)
Some studies show intermittent fasting — for example, eating within an 8-hour window or the 5:2 method — can help manage blood sugar levels, but this depends on your health condition.
🕒 How Long You Fast Matters
Here’s what typically happens at different fasting stages:
- 0–12 hours: Your body uses stored sugar for energy, lowering blood sugar.
- 12–18 hours: Fat burning kicks in, ketones rise, and some people feel sharper mentally.
- 24 hours: Autophagy (cell cleaning) begins — helping reduce inflammation.
- 36–48 hours: Growth hormones increase, aiding muscle repair.
- 72 hours: Stem cell regeneration may occur, boosting immune health.
✅ Other Health Benefits of Fasting
Think of fasting as a deep clean for your body:
- Improves insulin sensitivity (your body’s ability to use sugar effectively)
- Reduces inflammation
- Supports weight management
- Enhances mental clarity
- Strengthens immune function
⚠️ Risks to Watch Out For
Fasting isn’t for everyone. It can cause:
- Low energy
- Irregular eating patterns
- Blood sugar crashes (dangerous for diabetics)
- Social disruptions (e.g., skipping meals with family)
You should not fast if you:
- Have a history of eating disorders
- Are pregnant
- Are very physically active with high energy needs
- Have certain health conditions requiring regular meals
📌 Fasting & Diabetes — Special Considerations
If you have type 2 diabetes, fasting might help improve blood sugar control if done under medical supervision.
If you have type 1 diabetes, fasting is riskier because of insulin dependence — you’ll need constant monitoring to avoid low blood sugar or ketoacidosis.
Safety Tips:
- Always speak with a doctor before starting
- Monitor your blood sugar regularly
- Adjust medication with professional guidance
- Stop fasting immediately if you feel dizzy, weak, or unwell
🔑 Takeaway for Nigerians in the UK
Fasting can be a powerful tool for better health — but it’s not one-size-fits-all.
If you’re considering it for weight loss, religious reasons, or better blood sugar control:
- Do your research
- Seek medical advice
- Listen to your body
Your health always comes first. 💚
