How a Single Mistake Cost Me 6 Months (And Taught Me Everything)
It was early 2025. I stepped on the scale after months of gym time. Up 10 pounds. My heart dropped as the number glared back.
I’d been eating what I thought was clean. Salads, shakes, the works. But I ignored my daily calorie intake. Turns out, those “healthy” snacks added up fast. I felt defeated, like all effort was wasted.
That low point pushed me to dig deep. I learned calorie deficit explained isn’t about starving. It’s about smart choices. The aha hit: balance food with exercise calorie burn, not just cut everything. A related concept we explore is

Okay, let’s break this down. Think of your body like a car engine. It needs fuel (calories) to run. Too much, and you store fat. Too little, and it stalls.
