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.
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.
