Measure Baseline and Set a Doctor-Approved Target
1–2 weeks
Measure your current BMI (height and weight), document your baseline, and determine your target BMI range (18.5–24.9 for most adults). Consult with a doctor or registered dietitian to confirm the target is medically appropriate for your age, body composition, and health status — BMI is a screening metric, and some individuals have legitimate medical reasons for different targets. Create an initial plan (caloric target, activity level) with your healthcare provider's input.
Proof required
Submit: (a) your baseline BMI calculation (height, weight, date) and the target BMI range you are working toward, (b) a note or record from a healthcare provider (doctor or registered dietitian) confirming the target range is appropriate for you and noting any relevant health considerations, and (c) your initial plan summary (caloric target, planned activity level, timeline). The healthcare provider note does not need to be formal — an email confirmation or clinic visit note is sufficient.
What gets checked
- Baseline measurements are specific (actual height and weight on a named date, not estimates)
- Healthcare provider input is documented — pursuing significant weight change without medical input is a health risk, especially if starting BMI is below 18 or above 35
- Initial plan includes a timeline that is realistic — 0.5–1kg per week is the evidence-based sustainable rate
