**What is the consistency of a healthy portion size when it comes to meals?**
A healthy portion size typically involves balancing macronutrients across meals. For instance, a standard serving of lean protein such as chicken or fish should be around the size of a deck of cards, while vegetables should fill half the plate. Carbohydrates like grains should be limited to about a quarter of the plate. Incorporating healthy fats in moderation, like a small handful of nuts or a drizzle of olive oil, is also advisable. Listening to hunger cues can further guide appropriate portion sizes.
