Basics of nutrition and energy balance

Nutrition is the science of obtaining and utilizing nutrients from food.

It includes macronutrients (carbs, proteins, fats) and micronutrients (vitamins, minerals).

Energy balance is the equilibrium between food intake and energy expenditure.

Imbalance leads to weight changes.

Carbs provide primary energy, proteins aid growth and repair, and fats store energy and absorb vitamins.

Micronutrients like vitamins and minerals support immune function, bone health, and nerve signaling.

A balanced diet includes nutrient-dense foods: fruits, veggies, whole grains, lean proteins, and healthy fats.

Be mindful of portion sizes to avoid weight gain.

Stay hydrated and engage in physical activity for a healthy lifestyle.

Applying nutrition and energy balance principles leads to informed choices for well-being and healthy weight.

Small changes matter.
