Why Anchor Protein at 1.0g/lb of Body Weight?
Mainstream diet apps often suggest default percentage-based targets (e.g. 30% Protein, 40% Carbs, 30% Fat). For active weightlifters, this is highly inefficient[1]. If you eat in a high calorie surplus, percentage splits force you to ingest excessive amounts of protein that your body cannot utilize.
Nulls Tracker anchors your daily protein goals to exactly **1.0g per pound of body weight (2.2g/kg)**[2]. This ensures optimal muscle protein synthesis (MPS). The remaining calories are divided between dietary fats (essential for testosterone and hormone support)[3] and clean carbohydrates (vital for refueling muscle glycogen stores and power output)[4].
