Protein is an essential macronutrient, which means that it’s necessary for survival. It’s responsible for repairing and building muscle tissue. Carbohydrates are the body’s primary source of energy, while fats help to keep you full and satisfied between meals.
Although fat has been demonized in recent years as a result of various studies on its effect on cholesterol levels, there are some benefits to including it in your diet namely in terms of cardiovascular health.
Carbohydrates are essential for healthy bodily functions. They provide energy and promote a feeling of fullness, which can help keep you from overeating throughout your day.
Carbohydrates are also responsible for producing serotonin, an important neurotransmitter that plays a role in regulating moods. One caveat to be aware of is the glycemic index (GI), which measures how quickly carbohydrates enter the bloodstream after being consumed.
Typically high-glycemic foods include products made with refined flour or sugar including breads, pastries and sodas, they cause blood sugar levels to spike rapidly, resulting in subsequent dips over time leading us crave more sweets while providing little other nutritional value.
