Health Guides
Generic health advice uses population averages. You are not average.
These guides translate your body data into personalized decisions — calorie targets, macro splits, body composition, and fitness metrics calibrated to your specific numbers.
How Much of Your Weight Is Muscle vs Fat?
Knowing your lean mass versus fat mass in pounds changes how you think about your weight. Calculate the split and use it to set more meaningful goals.
How Many Calories Did You Burn During Exercise?
Your fitness tracker is probably overstating your caloric burn by 30-90%. Here is why — and how MET-based science gives you a more accurate number for any activity.
What Is Your Body Surface Area (BSA)?
BSA matters for medical dosing and burn coverage calculations. Calculate yours using standard clinical formulas and understand how it differs from BMI.
How Much Protein, Carbs, and Fat Should You Eat?
Two people eating 2,000 calories can have completely different body composition results depending on their macro split. Here is how to set yours for your specific goal.
How Much Protein Do You Actually Need Per Day?
The official RDA is a survival minimum, not an optimum. Active adults and anyone trying to build or preserve muscle need significantly more. Here is your real target.
How Many Carbs Should You Eat Per Day?
The right amount of carbs depends on how active you are, your metabolic health, and your goals. Here is how to calculate your range and choose the right approach.
How Much Fat Should You Eat Per Day?
Dietary guidelines recommend 20-35% of calories from fat. But type matters more than quantity. Here is how to calculate your daily fat target and what kinds to prioritize.
When Is Your Baby Due?
Only about 4% of babies arrive on their calculated due date. Here is how EDD is calculated, why it is a window not a deadline, and what the key milestones are along the way.
When Are You Most Fertile?
Your fertile window is only about six days per cycle — but knowing exactly which six days makes all the difference. Here is how to identify your window using cycle length, signs, and tracking tools.
When Will Your Next Period Arrive?
Your next period is predictable if your cycle is regular — and understandable even when it is not. Here is how to calculate it and what drives the variation.
How Much Weight Should You Gain During Pregnancy?
Pregnancy weight gain guidelines depend on your pre-pregnancy BMI — not a single universal number. Here is how to find your target range and what the extra weight is actually made of.
What Is Your Body Type? Ectomorph, Mesomorph, Endomorph
Ectomorph, mesomorph, and endomorph describe general body composition tendencies — not destiny. Here is how to identify yours and what it means in practice.
