The Metabolic Myth-Busting
!The 3,500 Calorie Rule
Old science claimed 3,500 calories exactly equalled 1 pound of fat. Modern metabolics show this is a static estimate that ignores **Adaptive Thermogenesis**. As you lose weight, your body becomes more efficient, often requiring periodic "Refeeds" or deficit adjustments to maintain progress.
Avoiding the Metabolic Crash
Aggressive deficits (>25% reduction) can trigger a physiological shutdown known as hypothalamic amenorrhea or significant thyroid down-regulation. Our "Standard" 20% deficit is the clinical gold standard for preserving hormone health while maximizing fat oxidation.
Deficit Science FAQ
Why focus on Protein?
Protein has the highest **Thermic Effect of Food (TEF)**. Your body burns 20-30% of protein calories just to process them, effectively creating a "hidden" calorie deficit.
Metric vs. Imperial?
Scientific studies use metric (kg/cm) for the MSJ equation. Our calculator converts imperial inputs to metric internallly to maintain clinical accuracy.
When to Adjust?
Recalculate your deficit for every **5-10 lbs** lost. A smaller body requires fewer calories to maintain its weight, meaning your maintenance baseline is constantly shifting.
