How you would build it
Your prompt to Claude
"Build a TDEE calculator. Inputs: weight in pounds, height in inches, age, activity level (sedentary, light, moderate, heavy), goal (cut, maintain, bulk). Calculate BMR using Mifflin-St Jeor, multiply by activity, adjust by 500 calories for goal, then split into 1.0g protein per pound, 25% fat, rest carbs."
A 165-pound, 70-inch, 32-year-old male at moderate activity targeting a cut gets 2,450 calories, 165g protein, 68g fat, 280g carbs.

FAQ
Can I customize the macro split?
Yes. Tell Claude your formula (e.g., 1.2g protein per pound, 30% fat, rest carbs). It builds the conditional.
Can clients see the result?
Yes — show the calorie target and macro split. Keep your internal coaching notes private. You choose per field.
Can I gate the result behind email?
Yes. Add email as a required field. The result only shows after the form submits, and the email lands in your dashboard.
Does it support metric units?
Yes. Add unit toggles as inputs, or build a separate metric version. Claude handles the conversions.
