Macro Tracking FAQs
What are macronutrients and why do they matter?
Macronutrients are the three primary energy-yielding nutrients required in large quantities: Protein (4 kcal/g), Carbohydrates (4 kcal/g), and Fats (9 kcal/g). Balancing their ratio optimizes muscle protein synthesis, athletic performance, hormonal equilibrium, and metabolic rate.
How does the Macro Calculator determine calorie and macro targets?
The calculator first establishes your Total Daily Energy Expenditure (TDEE) using the Mifflin-St Jeor equation and physical activity level, applies your desired surplus or deficit, and divides calories into scientifically supported gram targets based on International Society of Sports Nutrition (ISSN) guidelines.
What is the best macro split for fat loss?
For fat loss, a high-protein split (35–40% protein, 35–40% carbohydrates, 20–25% fat) is clinically proven to preserve lean skeletal mass, maximize diet-induced thermogenesis, and optimize satiety compared to standard lower-protein diets.
How much dietary fiber should I consume daily?
The Institute of Medicine (IOM) recommends 14 grams of dietary fiber for every 1,000 calories consumed (typically 28–38 grams daily for adults) to support gut microbiome diversity, insulin sensitivity, and digestive health.
