Track your meals, movement, and the measurements that actually matter. Snap a photo, let AI handle the details, and watch your Body Balance Score bring it all together—one clear, science-backed view of your health.
Weight and BMI offer only a partial view of your health. Research confirms that body composition, not just how much you weigh, is a far better predictor of long-term health.
PlateSage cuts through the guesswork. It synthesizes your eating, movement, and body measurements into one clear, actionable metric: the Body Balance Score. Understand your metabolic health more completely, without expensive equipment.
One score
Five components
Total clarity
Your Body Balance Score gives you a single, science-backed view of your metabolic health—so you can focus on what actually matters.
It combines five research-validated inputs: physical activity, waist-to-height ratio, waist-to-hip ratio, body roundness index, and meal quality. Each weighted based on its real impact on long-term health outcomes.
When your meals, movement, and body composition align, you notice:
Steadier energy through the day
Better sleep consistency
Fewer cravings and snack spirals
Less post‑meal sluggishness
Better focus and mood
A clearer sense of what works for your body
