New Delhi, May 22: Intermittent fasting, a dietary trend that focuses more on when you eat rather than what you eat, continues to gain momentum as a strategy for quick weight loss and improved metabolism. However, health experts are sounding a note of caution about its long-term impact, especially for women with underlying health conditions.
Fitness coach Bhavika Patel, in a post dated May 10, highlighted both the benefits and pitfalls of intermittent fasting. "It helps regulate insulin, supports digestion, and enhances fat-burning," she said. "But here’s the truth — intermittent fasting isn’t for everyone."
Patel warned that those with PCOS, thyroid disorders, or hormonal imbalances could experience adverse effects. She listed five common side effects:
1. Elevated cortisol (stress hormone): Extended fasting can stress the body, leading to fatigue, anxiety, and belly fat gain.
2. Hormonal imbalances: Women may experience disruptions in estrogen and progesterone, potentially affecting menstrual health and fertility.
3. Slowed metabolism: Over-fasting can put the body into "survival mode," leading to weight plateaus or gain.
4. Digestive issues: Bloating, acidity, and constipation may occur due to irregular meal timings.
5. Disordered eating habits: Fasting can create an unhealthy obsession with food, triggering binge-eating cycles and emotional stress.
On the other hand, Dr Bhavna Garg, Senior Consultant Dietitian at Yashoda Super Speciality Hospital, Kaushambi, emphasized the positive impacts in a March 2025 interview with HT Lifestyle.
"It helps reduce overall calorie intake, improves insulin sensitivity, lowers inflammation, and may even enhance brain health," she noted. Dr Garg added that the method suits those who seek dietary flexibility without cutting out food groups.
As experts remain divided, the consensus is clear: intermittent fasting isn’t a one-size-fits-all approach. Individuals considering this regimen are advised to consult healthcare professionals, especially if they have pre-existing conditions.
