Who should (and shouldn’t) eat buttermilk regularly
Good choice for: extremely low calorie (40 cal/glass), probiotic benefits, aids digestion, perfect meal accompaniment, virtually zero fat. If any of these apply to you, including buttermilk in your weekly rotation makes nutritional sense beyond just calories.
For most people eating a normal Indian diet, buttermilk is neither something to seek out nor something to avoid. It is a regular food that fits when you know the calorie count and plan accordingly.
How to reduce calories when eating buttermilk
Drink with every meal. 40 cal for a glass of probiotics and hydration. There is almost no reason NOT to have buttermilk with lunch and dinner. It aids digestion and adds satiety for negligible calories.
Replace sweet lassi with chaas. If you drink lassi daily, switching to buttermilk saves 140 cal per glass. Over a month of daily drinking: 4,200 cal saved. Over half a kilo of fat.
Add to your calorie plan as ‘free’. At 40 cal, buttermilk is close enough to zero that you can drink it freely without tracking. Very few Indian foods earn this status.
Masala chaas is still light. Adding roasted cumin, mint, and a pinch of chaat masala adds flavour for less than 5 extra calories. All the taste, none of the guilt.
