Calories &
Energy Balance
Your body runs on energy. Calories are that energy. Everything else in nutrition — macros, meal timing, supplements — sits on top of this foundation. Get this wrong and nothing else matters.

Common Traps
Where the math

Underestimating what you eat
Studies consistently show people underreport intake by 20–40%. "I eat pretty clean" is not a calorie count.
×
Overestimating what you burn
Your fitness tracker inflates calorie burn. Most people burn less than they think in a session.

Ignoring the weekend
A week's worth of deficit can vanish in two untracked days. Balance is weekly, not just Monday to Friday.
Keep it simple
Three rules.
Start here.
Start here.
I
Know your maintenance. Before chasing a deficit or surplus, know what "eating enough" actually looks like for your body.
II
Track with honesty. Measure or log food for at least two weeks. You'll be surprised — everyone is.
III
Adjust based on results. Calories are estimates. If nothing's changing after two weeks, change the number.
The Naked Truth
Every diet that's ever worked — keto, paleo, IF, clean eating — worked because it put you in a calorie deficit. The strategy changes. The maths doesn't.
You don't have to count calories forever. But you should count them once, properly, so you know what you're actually doing.
