How permanent is the effect of intermittent fasting on insulin resistance?
Intermittent Fasting and Health: Expert Q&A
Dr. Jason Fung, a leading authority on fasting for weight loss and diabetes reversal, answers common questions about intermittent fasting (IF), insulin resistance, and more.
Fasting and Insulin Resistance
Q: How long do the effects of fasting on insulin resistance last?
The effects aren’t permanent. Think of it like bathing—you can’t shower once and stay clean forever. To maintain reduced insulin resistance, ongoing fasting is required. Most weight loss diets (and fasting) aren’t “one-and-done” solutions.
Q: I’m a Type 2 diabetic. Is consuming whey protein post-workout harmful?
I don’t recommend it. Stick to whole, unprocessed foods.
Q: Can raw, unprocessed monk fruit be added to drinks during fasting?
Not recommended.
Aspirin Use
Q: Does aspirin artificially stimulate insulin secretion?
No.
Q: Does daily aspirin help prevent heart disease?
No. It’s only useful for secondary prevention (e.g., after a heart attack). The outdated recommendation for daily aspirin in adults over 60 applies only to specific high-risk patients, not the general population.
Q: Is daily aspirin suitable outside of occasional headaches?
No.
Dairy Intolerance and Fasting Tips
Q: On Day 3 of fasting, I’m experiencing dairy intolerance. Can I swap double cream with coconut milk?
Yes. Opt for coconut cream (thicker and richer) instead of coconut milk for better results.
Q: Do fat cells store micronutrients? How to maintain electrolytes during fasting?
Consider a multivitamin for extended fasts. For electrolytes, focus on sodium, potassium, and magnesium.
Q: Does taking 2 tablespoons of raw organic apple cider vinegar daily aid fasting?
Yes.
Q: After finishing a fast, does “alternate-day fasting” mean water-only or 500 calories as in Dr. Krista Varady’s The Every Other Day Diet?
Both approaches work. Choose what fits your lifestyle.
Key Takeaways
- Fasting improves insulin resistance but requires consistency.
- Avoid processed supplements like whey protein; prioritize whole foods.
- Aspirin has limited benefits for heart disease prevention in most people.
- Adapt fasting to your needs (e.g., coconut cream for dairy intolerance).
- Stay hydrated and monitor electrolytes during extended fasts.
Always consult a healthcare provider before starting fasting or making major dietary changes. 🕒🥑
