Intermittent Fasting (IF) has surged in popularity as a dietary strategy to enhance health, manage weight, and even improve longevity. By alternating periods of eating with periods of fasting, it promises benefits like better metabolic health and greater mental clarity. But is it right for everyone?
In an exclusive interaction with Onlymyhealth, Dr Shubendu Mohanty, Senior Consultant, Sharda Care - Healthy City, helped in explaining what factors determine its suitability and the precautions you should take before embarking on an intermittent fasting plan.
What Is Intermittent Fasting?
Intermittent fasting is not a diet but a pattern of eating. Popular IF approaches include the following methods:
16/8 Method: Fasting for 16 hours and eating during an 8-hour window.
5:2 Method: Eating normally for five days and reducing calorie intake to about 500-600 calories on two non-consecutive days.
24-hour Fast: Fasting for a full day, typically once or twice a week.
Alternate-Day Fasting: Alternating between normal eating days and fasting days.
Each method can suit different lifestyles, but the question still remains: is it suitable for you?

Factors That Determine If Intermittent Fasting is Right for You
Dr Mohanty pointed out that determining if IF is right for you is based on the following factors:
1. Your Health Goals
Weight Loss: IF can help create a calorie deficit and improve fat metabolism, making it an effective tool for shedding extra pounds.
Metabolic Health: Studies suggest that IF can improve insulin sensitivity, lower blood sugar levels, and reduce inflammation.
Mental Clarity: Fasting may boost brain function by promoting ketone production, which can serve as an alternative energy source for the brain.
2. Your Lifestyle
Work Schedule: If your job requires constant physical activity or irregular hours, prolonged fasting periods may leave you fatigued.
Social Life: IF can be restrictive during social events, which often revolve around meals.
Cultural/Religious Context: Consider whether fasting aligns with your values or fits into existing traditions.
3. Your Health Status
Existing Conditions: People with diabetes, eating disorders, or chronic illnesses should consult their doctor before attempting IF.
Medications: Some medications require food to prevent side effects or to improve absorption.
Pregnancy/Breastfeeding: Nutritional needs increase during these stages, making fasting potentially risky.
4. Your Personality and Eating Habits
If you’re prone to overeating after fasting or struggle with food-related anxiety, IF might exacerbate these tendencies.
Consistency is key. If you’re unable to stick to an eating window, the benefits of IF may not materialise.
Potential Side Effects Of Intermittent FastingAnd What To Be Cautious Of
Adapting to fasting can be uncomfortable, hence, it is important to note the following side effects:
- Hunger
- Irritability
- Fatigue
- Nutritional deficiency
- Overeating during feasting windows
- Impact on hormones (women, in particular)
- Risk of disordered eating
Tips for Trying Intermittent Fasting Safely
If you are thinking about IF, here are a few expert-approved safety tips you must follow:
- Begin with a shorter fasting period and extend it as your body adapts.
- Drink plenty of water during fasting hours to prevent dehydration.
- Prioritise whole, nutrient-dense foods to maximise the benefits of fasting.
- If you feel unwell or overly fatigued, reconsider your approach.
Thus, it’s clear that deciding whether intermittent fasting is right for you isn’t a simple yes-or-no answer—it depends on the factors mentioned above and your individual needs.
Conclusion
Intermittent fasting can be a powerful tool for improving health and achieving specific wellness goals, but it’s not a one-size-fits-all solution. It is important to consider your health status, lifestyle, and personality, and be aware of potential risks, to decide if this eating pattern is the right fit for you. Remember, the best diet is one that supports your well-being, aligns with your lifestyle, and is sustainable in the long term.
