Deficit
Coaches weight loss through small accountability circles instead of a paid coach
Deficit builds a personalized calorie plan from your starting data and revises it weekly, while an AI "Coach Bo" answers questions and adjusts the plan on request but explicitly stops short of medical advice. The core mechanic is a Circle — up to 12 invited people who see a one-line daily summary of everyone's calories, steps, and strength work, so a missed log gets called out socially instead of slipping by quietly. It prices itself directly against the alternatives: $19/year, or $35 once, versus $700+/month for GLP-1 drugs or $200+/month for a human accountability coach.
What holds up
- +Costs $19/year (or $35 once) versus $200+/month for a human accountability coach
- +Circles cap at 12 people by design — a small crew, not a public forum
- +Coach Bo sticks to the weight-loss plan and explicitly gives no medical advice
Mind the limits
- −The whole mechanic is public accountability — your off-plan days are visible to your Circle too
- −Coach Bo won't give medical advice, so it can't help with GLP-1 side effects directly
