Patient education toolsKnow your numbers before you start.
Enter your details once and every calculator on this page updates: your BMI, what the GLP-1 trials would mean at your weight, your daily calories, your protein target and your water target. Same formulas our providers and coaches use. None of them replace a licensed provider.
Tool 1 of 5
Body Mass Index (BMI)
BMI compares your weight to your height using the standard formula used by the CDC and WHO. It’s a screening number, not a diagnosis, and it’s one of the first things a provider looks at.
Why it matters here
Your BMI is one of the first things your intake reviews. It helps point you toward the program most likely to fit: microdosing from BMI 20, full-dose GLP-1 from BMI 30, or 27 with a weight-related condition.
What to do with your result
Treat it as a starting point. Your provider looks at your full history, and confirms eligibility before anything is prescribed.
What’s my BMI?
Edit your numbersA healthy-weight BMI at your height is about 115–154 lb.
Educational only, not medical advice. BMI doesn’t account for muscle, bone density or body shape. A licensed provider confirms eligibility at intake.

What Could I Lose on a GLP-1?
See what the published trial averages would look like at your weight, week by week, next to what happened on placebo.
Why it matters here
GLP-1 results build slowly. Most of the change happens over months, not weeks, and the average flattens out after about a year. Seeing the shape helps set realistic expectations.
What to do with your result
Use it to picture the pace, not to set a target. In the trials, some people lost far more than average and some far less. Your provider sets your dose; your coach helps you keep the results.
What could I lose on a GLP-1?
Edit your numbersIllustration only. The end points are the published trial averages for everyone who started (semaglutide 2.4 mg: 14.9% at 68 weeks; tirzepatide 15 mg: 20.9% at 72 weeks). The curve between is smoothed to the general shape seen in the trials. Your results will differ. Trials used brand-name medicine; compounded versions aren’t FDA-approved. See the full trial data.
Tool 3 of 5
Daily Calorie Needs (TDEE)
Total Daily Energy Expenditure is roughly how many calories your body uses in a day, including activity. It’s calculated with the Mifflin-St Jeor equation, the formula most widely used in clinical nutrition today.
Why it matters here
GLP-1 medicines work partly by lowering how much you eat compared with this number. Knowing your baseline helps you and your coach make sense of the appetite changes that happen on your program.
What to do with your result
Don’t chase an aggressive deficit on your own. Eating too little makes it harder to keep muscle and to stick with it. Your coach turns this into a realistic eating pattern alongside your medication.
How many calories do I actually burn?
Edit your numbersMifflin-St Jeor equation, adjusted for activity. Estimates vary by 10% or more from person to person. Don’t go below about 1,200 calories a day (women) or 1,500 (men) without your provider’s guidance.
Tool 4 of 5
Protein Target
Muscle loss on GLP-1 therapy is largely about getting too little protein and too little strength training. Bold You coaches set every patient’s target from session 1. See where you land.
Why it matters here
A smaller appetite makes it harder to eat enough protein. Losing muscle along with fat slows your metabolism and makes results harder to keep.
What to do with your result
Use the range as a target, not a rule. Your coach narrows it based on your training, and adjusts it every session.
How much protein do I need to protect muscle?
Edit your numbersWhat reaching the low end of your range could look like:
That adds up to about 147 g.
How coaches set your protein target
Based on 1.6 to 2.2 g of protein per kg of body weight. Food amounts are approximate. Educational only; needs vary with kidney health, age and training, and your provider and coach confirm your number.
Tool 5 of 5
Hydration Target
Hydration has an outsized effect on how you feel on GLP-1. Water and timing are covered in their own coaching module.
Why it matters here
Eating less also means less water from food. Dehydration can make nausea, headaches and constipation worse, so it’s worth ruling out before assuming your dose needs to change.
What to do with your result
If you have a heart, kidney or other condition that affects fluids, this guideline may not apply to you. Talk to your provider first.
How much water should I be drinking?
Edit your numbersThat’s about 12.5 cups (8 oz each). Spread them through the day.
A common wellness guideline: half your body weight in ounces, plus about 16 oz on active days. Not a prescription. Some heart and kidney conditions require limiting fluids; always follow your provider.
