Calculator Questions

Are these calculators accurate?

They are well-established estimates (for example, Mifflin-St Jeor for calories and Epley for one-rep max), accurate enough to guide everyday decisions. Track real-world results for 2–3 weeks and adjust — the trend matters more than any single number.

Should I use BMI to determine whether I'm healthy?

No — BMI is a screening measure, not a diagnosis. It doesn't distinguish muscle from fat. Use it alongside waist size, activity, sleep, blood work and how you feel, and talk to a clinician if you're concerned.

Are calorie calculator results exact?

No. They estimate your needs within a few hundred calories. Bodies, tracking errors and day-to-day activity all vary. Start from the estimate, eat consistently, and adjust intake by 100–200 kcal based on the scale trend.

How should I interpret protein estimates?

As a daily range to distribute across 3–4 meals (roughly 25–40g each). Hitting the range most days matters far more than perfect precision on any single day.

How much water should I drink each day?

Most adults do well on 2–3 liters of total fluids, more with training or heat. Pale-yellow urine, steady energy and rarely feeling thirsty are better guides than a fixed target.

Important: estimates, not medical advice
