Do Diet Fads (Keto, Intermittent Fasting) Affect Skin Health?



πŸ₯— Do Diet Fads (Keto, Intermittent Fasting) Affect Skin Health?


Every few months, a new diet trend takes over—keto, intermittent fasting, low-carb, detox diets—and people rush to try them for quick weight loss. But while these diets may change your waistline, they also silently affect your skin health.


Let’s understand how.


πŸ– Keto Diet and Skin



Keto means eating very low carbs and high fat.

• For some, it helps reduce acne because of lower sugar intake.

• But for others, excess fats and lack of certain nutrients can trigger “keto rash” (red, itchy rashes) or worsen oiliness and breakouts.

• Lack of fruits and fiber may also make skin look dull.


⏰ Intermittent Fasting and Skin


This diet is all about timed eating windows.

• Fasting can sometimes reduce inflammation, which is good for skin.

• But long gaps without water or food may cause dryness, headaches, and even worsen eczema flare-ups.

• If meals are not balanced, skin may miss out on vitamins like B, C, and zinc, which are essential for repair.


πŸ₯¦ Common Problems Seen in Diet Fads

1. Sudden breakouts – due to imbalance in hormones and gut health.

2. Hair fall and brittle nails – from protein or vitamin deficiencies.

3. Pale or tired-looking skin – if iron and B12 intake drops.

4. Dry, itchy skin – from dehydration and missing healthy fats.


✅ Dermatologist’s Advice



• If you follow any diet trend, make sure it’s supervised by a doctor or dietitian.

• Don’t cut out essential nutrients like proteins, healthy fats, and vitamins.

• Always hydrate well during keto or fasting plans.

• Remember, balanced diet > fad diet when it comes to glowing, healthy skin.


🌟 Final Word


Your skin is often the first to show the side effects of extreme diets. Keto and intermittent fasting are not “bad” by themselves, but if done incorrectly, they can leave your skin dry, dull, or acne-prone. Instead of chasing quick fixes, focus on a sustainable, balanced way of eating—your skin (and body) will thank you.
