Guides that explain the numbers
A calculator hands you a figure. It rarely tells you which population the equation was built on, how wide the error bars are, or what the number fails to capture. These guides cover that ground, citing the original papers so you can go and read them.

Meal Timing and Frequency: What the Evidence Supports
Six small meals, three square meals, one eating window: when calories and protein are matched, most of the difference disappears. Here is what timing genuinely changes.
How to Measure Body Fat at Home: Methods Ranked by Accuracy
Calipers, tape, smart scales and BMI-based equations all claim to measure body fat. Here is how each one works, how wrong it typically is, and which to trust.
Cardio vs Strength Training: What Each One Actually Does to Your Body
Endurance and resistance training produce different adaptations with little overlap. What each one changes, where they conflict, and how to run both at once.
Weight Loss vs Fat Loss: Why the Scale Lies to You for Three Weeks
Scale weight measures everything in your body, most of which is not fat. Here is what actually moves the number day to day and how to read the signal underneath.
NEAT: The Largest Movement Variable Nobody Tracks
Non-exercise activity thermogenesis varies by hundreds of calories a day between similar people, and it falls quietly when you diet. Here is what the data shows.
The Menstrual Cycle and Training: What the Evidence Does and Doesn't Support
Cycle-based training programmes promise more than the research delivers. Here is what the literature actually shows, why its quality is poor, and what is worth acting on.
How to Create a Calorie Deficit That Holds
A calorie deficit is a gap between intake and expenditure, not a figure a calculator hands you. How to size one, test it against your own data, and keep it.
Progressive Overload: The Only Rule Training Cannot Skip
Muscle and strength adapt to demands they have not already met. Progressive overload is the principle behind that, and the ways it actually gets applied.
How Much Protein You Actually Need: Reading the Evidence
The gap between the official RDA and what the training literature supports is large, and both numbers are answering different questions. A look at the dose-response data, meal distribution, protein during a deficit, and the kidney question.
VO2 Max Explained: What It Measures and How Much of It You Can Change
VO2 max is the strongest single measure of cardiorespiratory fitness, and a stubbornly genetic one. What it measures, and how much training actually moves it.
How Fast Should You Lose Fat? Setting a Rate You Can Actually Hold
The right rate of fat loss is a percentage of your body weight per week, not a fixed figure. Here is what faster loss costs you and how to pick a defensible pace.
Protein Requirements: From the RDA Floor to the Athletic Ceiling
The 0.8 g/kg allowance came from nitrogen balance studies with real blind spots. How it was derived, what protein quality adds, and who needs more.
Read the guide, then run the numbers
Each article links to the calculators it discusses, and each calculator shows the equation and source behind its output. Every article carries a named author and a publication date. Nothing here is medical advice. Our editorial policy sets out how we source, review and correct what we publish.
