Most diets fail because tracking feels like homework

The research is consistent: it’s not the perfect plan that gets results — it’s showing up. Sphere exists to make showing up effortless.

Why logging

Tracking works

Across weight-management research, people who consistently record what they eat lose more weight and keep it off longer than those who don’t.

Why consistency

Showing up beats perfection

Frequent self-monitoring — not perfect days — is one of the strongest predictors of long-term weight maintenance. Sphere is built around making that easy.

The math

Clinical-grade targets

Your calorie goal starts from the Mifflin-St Jeor equation used in clinical nutrition practice, adjusted for your activity and pace.

Your plan is ready in two minutes

Answer a few questions about your goal, pace, and lifestyle. Sphere builds a calorie and macro plan around you — not a generic 2,000-calorie template — and you can edit anything.
