Let’s talk about the “I drank two Dr Peppers and my milk increased” story
Because sometimes… it actually does feel true
And also
It’s not magic
Here’s what’s usually happening 👇
If someone has been:
• Under-eating (hello, newborn survival mode)
• Accidentally in a calorie deficit
• Mildly dehydrated
• Running on caffeine and crumbs
Then suddenly they drink two regular Dr Peppers
What changed?
✨ Fluids
✨ Sugar (aka quick carbohydrates)
✨ Calories
A regular Dr Pepper has about 150 calories and ~40g of sugar
Two of them = ~300 calories and a decent fluid bump
If your body has been slightly under-fueled, that quick energy can:
• Raise blood glucose
• Lower stress hormones like cortisol
• Signal “we’re safe, we have fuel”
• Improve milk ejection (letdown can be stress-sensitive)
Milk production is energy-intensive
Your body prioritizes survival first
If you’re chronically under-eating, your supply can dip because your body is conserving
So when you suddenly provide:
Calories + hydration + a little nervous system relief
Supply can perk up
Not because Dr Pepper has secret lactation powers
But because your body finally got enough input
Important nuance:
If you’re already well-fed and hydrated, drinking soda won’t increase supply
More milk still comes from milk removal
Milk out = signal to make more
But if someone was unintentionally undernourished?
The “Dr Pepper boost” is really a calorie and hydration correction
This is also why some people notice supply dips when they’re:
• Dieting
• Skipping meals
• Post-illness
• Extra stressed
• Back at work and forgetting to eat
•Periods have returned
The takeaway isn’t “drink soda to make milk”
It’s this:
Your body needs adequate fuel and fluids to comfortably maintain production
Eat consistently
Drink to thirst
Remove milk regularly
And if two Dr Peppers were the thing that got calories into you that day?
No shame in that game
Sometimes supply stories are less about magic foods
And more about basic physiology catching up 💛
