Question 1

What formula does the James Smith Calculator use?

Accepted Answer

This tool utilizes the Revised Harris-Benedict Equation (1984), which significantly improves accuracy for modern body compositions compared to the original 1919 baseline formula.

Question 2

How often should I recalculate my macros?

Accepted Answer

You should revisit the James Smith Calculator every time you drop or gain roughly 3 to 5 kilograms (7 to 10 lbs), as your metabolic baseline will naturally shift alongside your new weight.

Question 3

Is a calorie deficit safe for long-term weight loss?

Accepted Answer

Yes. The calculator computes a sustainable, moderate deficit designed to protect your energy levels and prevent metabolic adaptation, allowing you to lose weight without starving yourself.

Question 4

What is BMR in the James Smith Calculator?

Accepted Answer

BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to stay alive. The James Smith Calculator uses your gender, age, weight, and height to calculate this baseline number.

Question 5

What is TDEE and how is it calculated?

Accepted Answer

TDEE (Total Daily Energy Expenditure) is your BMR multiplied by an activity level multiplier. It represents the actual total calories you burn every 24 hours based on your lifestyle and exercise habits.

Question 6

How much protein should I eat according to the James Smith method?

Accepted Answer

The James Smith Academy recommends 2.0g of protein per kilogram of bodyweight per day. This is kept intentionally high to support muscle recovery, keep you full during a deficit, and protect your metabolism.
