Quick numbers, no login

Rough math you can run in ten seconds. None of it is a diagnosis, and a calculator has never met you. If something here looks off, that is your cue to get real labs and a real conversation, not to panic at a number.

Body mass index

What's my BMI?

BMI is a blunt instrument. It cannot tell muscle from fat, so a guy who lifts can read "overweight" while carrying very little of it. Useful as a rough flag, useless as a verdict.

Daily calories

How much should I eat?

An estimate of what you burn in a day (the Mifflin-St Jeor equation, the one most dietitians actually use). Eat around maintenance to hold, a bit under to lose. Bodies vary, so treat this as a starting line, not gospel.

Caffeine

Is coffee wrecking your sleep?

Caffeine has a half-life of about six hours, so half of that afternoon cup is still in you six hours later. If you lie awake wired or your anxiety spikes at night, this is often the quiet culprit. See how much is still circulating at bedtime.

Rough guide: brewed coffee about 95mg a cup, espresso shot 65mg, energy drink 80mg, tea 45mg, cola 35mg.

Alcohol

How much are you actually drinking?

No lecture, just the math against the usual guidelines. One drink means a regular beer, a glass of wine, or a shot. Count an honest week, the kind you would not round down on.

Low testosterone

Could it be low T?

Check the ones that have been true for a few weeks or longer. This is a gut-check, not a blood test. The only thing that settles it is actual labs, and plenty of these overlap with stress, bad sleep, or just a rough season.

None of these replace a clinician. If a number or a screen here lines up with how you actually feel, that is worth a real workup. Reach out and we'll sort out what's actually going on.
