If you’ve ever tried to lose weight, you’ve probably heard the phrase: “Calories in, calories out.” While thermodynamic laws dictate that you must be in a caloric deficit to lose weight, focusing solely on calories ignores a crucial element of human metabolism: macronutrients.
What are Macros?
Macronutrients, or “macros,” are the three primary components of food that provide energy: protein, carbohydrates, and fats. Each plays a distinct role in how your body functions, recovers, and signals satiety.
The Quality Difference
Two meals can each provide 500 calories while differing in protein, fibre, saturated fat and other nutrients. The ingredients and portions determine those amounts; the meal’s name alone does not tell you its nutritional quality.
Compare the nutrient information alongside the calories. A salad with chicken, quinoa, avocado and vegetables has a different composition from a burger meal, but neither name guarantees a particular blood-sugar response or how long you will feel full.
