That's 5,929 calories per week. Nearly 2 pounds of fat you could have lost... but didn't, because these calories were invisible.
They're called "Sneaker Calories" — and they're the #1 reason you can't break through your plateau, no matter how much willpower you have.
In one week, that's 5,929 calories
= 1.69 lbs of pure fat
Three independent studies prove liquid calories are the invisible weight loss killer
Harvard Medical School tracked 3,847 dieters for 18 months. Nearly 3 out of 4 completely forgot their daily beverages.

UCLA study: Dieters who tracked liquid calories lost 4.5x more weight than those who didn't — even with identical food intake.

Johns Hopkins: 63% of plateau dieters started losing again within 14 days after tracking sneaker calories.

Dr. Richard Mattes, Purdue University's leading nutrition researcher, discovered the mechanism:
"The brain doesn't register liquid calories the same way it registers solid food."
Your satiety hormones (leptin and ghrelin) barely respond to beverages — meaning 320 calories of bubble tea feels like zero to your brain.

The world's first AI system specifically designed to catch the calories your brain ignores
Our AI (powered by Claude 3.5 Sonnet — the most accurate food recognition AI in 2025) analyzes your meals in 3 seconds.
Every evening, you get a gentle prompt: "Did you have any beverages or snacks today?" Takes 30 seconds to answer with visual icons (no typing).
Coffee? Bubble tea? Wine? Cooking oil? The Catcher finds them all. You simply tap the icons — boom, tracked.
For the first time ever, you'll know your TRUE calorie intake — not the fantasy number that's been sabotaging you.
Other apps require manual searching through databases. Sneaker Catcher uses visual icons — tap and done.
Behavioral psychology timing: 8 PM is when your memory is sharpest for the day's beverages.
"You caught 1,240 sneaker calories this week — that's why you lost 0.4 lbs even though you had pizza!"
"You're in the top 12% of Sneaker Catchers this week!" No guilt, just awareness.
