What a food journal is (and why it works)
Food journaling is a “low numbers” approach to awareness: what you ate, when, and how it affected your hunger, energy, mood, and cravings. It works because it’s easy to do consistently, and consistency is what reveals patterns.
The simplest daily routine
- After each meal, write one message with what you ate.
- Add one sentence about hunger/energy/cravings (optional).
- Once per week, ask for patterns and one small change to try.
Copy-paste journal prompt (one message)

Weekly reflection prompt
Based on my food journal entries this week: 1) Summarize the top 3 patterns you see 2) Identify the 2 situations where I overeat / snack most 3) Suggest 1 small change for next week that is easy to follow
