Why Nutrition Isn’t Just About Weight

If you’ve ever felt irritable after skipping a meal or noticed how comfort food lifts your mood (even briefly), you already know this truth: what we eat affects how we feel.

Mood swings, anxiety, low energy, and even depression aren’t just emotional challenges — they’re often signs of biochemical imbalances rooted in our gut, nutrient status, and food choices.

At L&B Clinic, we’ve seen first-hand how poor nutrition fuels emotional dysregulation, and how targeted nutritional interventions can shift the mental health trajectory of both children and adults. This isn’t just theory — it’s backed by neuroscience, clinical nutrition, and gut-brain axis research.

The Gut-Brain Axis: Your Second Brain in the Gut

The gut is home to over 100 million neurons — and 90% of your serotonin, your brain’s “feel-good” neurotransmitter, is made in the digestive tract. This means that a disturbed gut can directly impact your emotional state.

GUT 360, L&B Clinic’s advanced gut microbe test in delhi, helps decode how imbalances like:

• Dysbiosis (bad bacteria overgrowth)
  
  

• Leaky gut syndrome
  
  

• Low microbial diversity
  
  

…can trigger or worsen conditions like:

• Anxiety
  
  

• Brain fog
  
  

• Mood swings
  
  

• Chronic fatigue
  
  

• PMS-related emotional sensitivity
  
  

Dr. Deepika Krishna says:
“We often treat the gut before we treat the mind — because inflammation, malabsorption, and gut toxins silently hijack mental well-being.”

The Science Behind Nutritional Psychiatry

Nutritional psychiatry is a growing field that looks at how specific nutrients influence mood, cognition, and resilience.

A study in The Lancet Psychiatry (2015) showed that dietary patterns high in processed foods were associated with increased risk of depression and anxiety.

A poor diet can lead to:

• Neuroinflammation (inflammation in the brain)
  
  

• Insulin resistance
  
  

• HPA axis dysfunction (stress hormone imbalance)
  
  

• Oxidative stress
