Calculate your body mass index (BMI)
BMI, or Body Mass Index, is a measurement that uses your height and weight to estimate whether you’re in a healthy weight range for your height.
This Body Mass Index (BMI) calculator is for informational purposes only and is not a substitute for professional medical advice. Many things affect health and body composition and BMI may not accurately reflect the health of all individuals, particularly in those under the age of 18, elderly, those who are pregnant or lactating and those with increased muscle mass. BMI is one potential health indicator and should be considered with other factors when assessing each individual's health.
The BMI calculator does not determine eligibility for weight loss treatment provided through the Felix Health platform. Consultation with a healthcare practitioner is required to assess suitability of medical treatment based on individual health and medical history.
Based on your BMI, you might qualify for our Weight Loss program.

Experience from start to almost finished in terms of getting things set up has been dreaming professional and rewarding and feeling like someone was taking care of me and my issues. Which I have to say was a nice feeling. I would recommend Felix to anyone as I think they're a very helpful service.

I recently moved to a smaller city in British Columbia. I had a family doctor in my last community but after moving I no longer have one. Felix Health has been a great resource. The clinicians are consistently kind, thoughtful, encouraging and clearly dedicated to making sure that my overall well-being is the focus – not just my physical self

Frequently Asked Questions
Bmi Calculator
- Underweight: BMI below 18.5
- Healthy weight: BMI 18.5–24.9
- Overweight: BMI 25–29.9
- Obesity: BMI 30 and above
Please note that these ranges help assess potential health risks, but they don’t tell the whole story. Speaking with a healthcare provider is always recommended.
Several factors can influence your body size and health beyond just your BMI. These factors are why BMI should always be interpreted as part of a broader health assessment.
Genetics: Your genes can affect how and where your body stores fat.
Lifestyle: Diet, physical activity, sleep and stress all play a role.
Certain health conditions or medications: Medical conditions and some medications can impact weight and stored fat.
Age and sex: Body composition often changes over time and can vary between men and women.
Race and ethnicity: Research shows that BMI doesn’t reflect body composition the same way across all groups. Factors like muscle mass, fat distribution and metabolic conditions can differ based on ethnicity. Cultural perceptions of weight and access to care may also shape someone’s experience with weight management.
BMI is a helpful screening tool, but it should always be interpreted as part of a broader health assessment—one that accounts for who you are as a whole person.

BMI is a simple calculation that uses your height and weight to estimate your body fat. Remember that it is an estimate, it is not accurate in some cases and it does not diagnose health.
To calculate it in metric units, divide your weight in kilograms (kg) by your height in meters (m) squared.
For example, if you weigh 70 kg and are 1.75 m tall: 70 ÷ (1.75 × 1.75) = 22.9
To calculate it in imperial units, divide your weight in pounds (lbs) by your height in inches (in) squared, and multiply the result by 703.
For example, if you weigh 154 lbs and are 5’9″ (69 inches) tall:154 ÷ (69 × 69) × 703 = 22.7
But, no need to do the math yourself. Our calculator gives you a result in seconds.
If your BMI suggests that you have overweight or obesity, you might be considering changes to help you on your weight management journey in order to support your health.
At Felix, we offer personalized weight loss treatment plans designed to support you safely and sustainably.
Our approach combines medical treatment options (if appropriate), sustainable lifestyle choices (like diet and physical activity) with ongoing care from a Canadian healthcare practitioner to support you on your health journey.
Body Mass Index (BMI) is a simple calculation that uses your height and weight to estimate your body fat. It can help categorize weight as underweight, healthy weight, overweight, or obesity.While it’s a useful screening tool, BMI doesn’t account for muscle mass, bone density, fat distribution or individual health differences. It’s designed for adults and is only one piece of your overall health picture.
Your BMI category offers a general idea of how your weight may relate to your risk for certain health conditions.
- Underweight: Possible increased risk for nutritional deficiencies, weakened immunity and osteoporosis.
- Healthy weight: Generally associated with lower risk for most weight-related health conditions.
- Overweight: May increase risk for type 2 diabetes, heart disease and other metabolic conditions.
- Obesity: Higher likelihood of developing heart disease, diabetes, high blood pressure and certain cancers.
Felix 101
Absolutely. Our online assessments have been designed to ask all the necessary questions required for diagnosis. We’ve worked with specialists to create an assessment process that can provide sufficient information for the healthcare practitioner to determine whether or not you are eligible for a prescription and craft an appropriate treatment plan.
No. Felix provides a faster, hassle-free way for you to get a treatment plan for certain conditions, but our service does not replace your primary care provider. For matters that extend beyond obtaining a lifestyle treatment safely and easily, we encourage you to consult your primary health practitioner in person — whether for checkups, personal health concerns, or to inform them about your current treatments or treatment plans.
Call 911 or proceed to your nearest emergency room immediately. Felix is not intended for medical emergencies. Once the emergency has been addressed or resolved, contact your prescribing practitioner to inform them of your experience as this may impact your current treatment plan.
Felix is Canada’s first truly integrated healthcare platform. We provide on-demand treatment for everyday health needs like weight loss, mental health, sexual health, and more. Founded in 2019, our digital-first approach to healthcare includes everything from diagnosis to prescription — all accessible from the comfort of home.
Anyone who is 18 years or older (16 or older for acne and birth control prescriptions), and is located in Alberta, British Columbia, Manitoba, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, Saskatchewan or Ontario. We cannot ship treatments outside of these provinces at this time.
Insurance
Treatment coverage varies greatly between different insurance plans.
The good news is that if you are covered, Felix can bill your insurer directly, and then process your treatment plan at no additional cost to you. We recommend that you upload your private and/or provincial benefit card during the online visit so that our pharmacy partner can apply any coverage you are eligible for before processing your treatment plan.
Insurance coverage for treatment plans through Felix doesn’t include the cost of your visit.
Go to Billing where you can add or update your insurance information on file.
You will find the official receipt for your medication costs within your package from the pharmacy. This receipt can be used to submit a manual claim directly to your insurance/benefits provider. Future refills will be direct-billed directly to your insurance provider, once you have uploaded your insurance information from the Billing tab of your account.
The coverage you are eligible for will not be deducted until the pharmacy processes your refill, so the price you see in your profile is the estimated maximum medication cost before benefits. Once the pharmacy ships your meds, the actual cost will be displayed for the respective refill.
OHIP+ covers some birth control for eligible residents of Ontario who are under 25 years old and do not have private insurance. You can check if your birth control medication is covered here. Make sure to upload your Ontario health card during your online visit so our pharmacy partners can apply your coverage directly.
Medication coverage varies greatly between different plans, provinces, and has specific criteria that determine eligibility. For private insurance, we recommend contacting your benefits administrator with your details and the Drug Identification Number (DIN) and the drug name to determine your coverage.

A Felix online visit is considered asynchronous since it is conveniently completed through a secure chat bases system. Currently, asynchronous visits are not covered by insurance or provincial health plans so you will be charged a visit fee, depending on the category of treatment you are requesting.
Online Visits

No. We use an asynchronous telemedicine model so you can complete your online visit in your own time and we save your progress so you can come back later to finish it.
If you are completing a visit in the mental health or weight loss categories, your healthcare practitioner may require a phone or video call to discuss your medical profile further during the assessment process.
Most assessments do not require a phone or video conversation. Once a prescriber has reviewed the info in your assessment they will respond to you via secure instant messages that you can access within your Felix account.
If you are completing a visit in the mental health or weight loss categories, your healthcare practitioner may require a phone or video call to discuss your medical profile further during the assessment process.
After creating an account, you will complete a medical assessment for evaluation by one of the Felix healthcare practitioners.
During your assessment, you will have the opportunity to send your practitioner questions via secure messaging.
In most cases, practitioners will complete your assessment with secure messaging alone but sometimes they may determine you require an audio or video visit and/or further diagnostic testing to help determine the best treatment plan for you.
If your practitioner has determined a prescription treatment is appropriate, they will approve your visit and write you a prescription. Our pharmacy will then ship your prescription to your home.
You’ll be able to message your healthcare practitioner if you have questions or want to make changes to your treatment at any time.
You can expect to receive a response from a healthcare practitioner within 48 hours of submission. Delays may occur at high volume periods or over statutory holidays – we thank you for your patience and look forward to supporting you.
Great, you’ve already taken the first step! Next, a healthcare practitioner will review your assessment and if necessary, will send you a link to book an online audio or video appointment with them. This appointment will help them determine the best treatment plan for you. If your healthcare practitioner thinks you will benefit from an available medication, they will write you a prescription. Our pharmacy can ship your medication to your home if you would like your medication dispensed through the Felix Pharmacy network.
