Most Copilot frustration is not the model—it is the prompt. Vague questions like "am I healthy?" or "fix my diet" force the assistant to guess what you mean, which produces generic advice you could find on any blog. Useful prompts remove the guessing.
A good prompt gives three things: what data window to read, what decision you are trying to make, and how many options you want back.
Think of Copilot as a coach who has only seen your recent logs. It cannot read your mind about goals you never entered. Before you prompt, log meals, movement, and sleep honestly for at least three days so answers reference your week—not population averages.
Five patterns that work
- Timeframe first. Say "last 7 days" or "since Monday" so the reply matches the trend you care about.
- One question. Ask about protein, recovery, or meal timing—not all three in one message.
- Trade-offs, not verdicts. Request two options with pros and cons instead of a single command you may ignore.
- Anchor to a feeling. Add "I feel sluggish on lift days" so suggestions respect lived energy, not only charts.
- Small next step. End with "one change for tomorrow" so output stays actionable.
Prompts to avoid
Skip diagnosis language ("do I have a deficiency?"), extreme targets ("get me to 10% body fat"), and multi-page life overhauls ("rebuild my entire routine"). Copilot is built for everyday habit-building, not replacing clinicians. If a question involves medication, injury, or disordered eating, stop and use a qualified professional.
How to review the answer
Treat every reply as a draft hypothesis. If it suggests eating more protein but you already hit your target four days this week, say so in a follow-up. If it recommends training hard but you slept under six hours three nights running, ask for a lighter plan. Good prompting is a short conversation, not one magic sentence.
Log consistently for several days in Ohga before you expect sharp answers—Copilot needs your meals, sessions, and sleep to spot patterns. Start with one focused question, compare the suggestion to how you actually feel, and adjust. The goal is fewer decisions from scratch, not outsourcing judgment.
