Share your goal with our care team

Tell us your goal. It reaches our care team with your name and number, and your doctor decides what your plan includes.

How many kilos would you like to lose?

By tapping Send, you agree: You may call or email me on these about Metaboliq, and message me on WhatsApp on this number. I can ask you to stop at any time, and the answers I gave above go with this so the person who calls has read them.

The only answer that goes with your name and number is your goal. The numbers you typed into the calculator stay on this page.

Whatever the estimate, the next step is the same: a home panel measures your blood sugar, lipids and liver, and a doctor reads the results with you before anything is planned.

How this is worked out

  • Formula: Mifflin-St Jeor, from weight in kg, height in cm and age, with one constant for women and another for men.
  • Source: Mifflin MD, St Jeor ST et al., Am J Clin Nutr 1990;51(2):241-247.

An estimate from a published formula, not a diagnosis. Your doctor decides your plan.

Your measurements never leave this phone: the calculation runs in your browser and we do not record it.

Questions, answered

What is BMR?

Basal metabolic rate: the energy your body uses at complete rest to breathe, keep your heart beating and stay warm. It is usually the largest part of what you use in a day.

How is BMR calculated here?

With the Mifflin-St Jeor equation (Am J Clin Nutr, 1990), from your age, height, weight and sex recorded at birth. It is an average, and two people with the same inputs can differ by a couple of hundred kcal.

Should I eat my BMR?

No. It is what your body spends lying still, not a plan. What you eat is set with a doctor and a nutritionist after your blood work, around enough protein, fibre and food.

How is BMR different from daily calorie needs?

Daily needs, or TDEE, add everything you do on top of rest. The calorie calculator multiplies this resting figure by how much you move in a normal week.

Does muscle change my BMR?

Yes. Muscle uses more energy at rest than fat does, which is one reason a good plan protects muscle while you lose weight: strength training and enough protein.

Is anything I type stored?

Your measurements stay on your device. The arithmetic runs in your browser and is never sent. Only a name, number and goal you choose to send in the goal step reach us.
