Carbohydrates provide fuel for the central nervous system and energy for working muscles. There are two forms of carbs such as Simple Carbs and Complex Carbs. Simple Carbohydrates consist of mostly sugary and packaged foods with a high GI. These foods will provide you with high energy spikes due to the sudden change in blood sugar levels, but can leave you feeling lethargic again after a short period of time. Complex Carbohydrates consist of wholegrain foods such as wheat, oats, lentils, brown rice and have a lower GI, helping you to feel fuller for a lot longer. So why do we need them?
Gives You Energy
Carbohydrates contain glucose which once entering the blood stream can become immediately used for energy. When glycogen stores in the body are depleted due to vigorous exercise or a low carb diet - the body burns fat for energy. If neither fat nor carbs are available as an energy source, the body will burn protein as a last resort which will result in a loss of muscle mass. Fuelling your workouts with carbohydrates is to ensure that your body has the building blocks for an energetic workout with sufficient amount of fats and protein in the body.
Many complex carbohydrates contain fibre which help to regulate your bowl movements and improve digestion. Toxic waste will be removed from the body more efficiently and will lead to less stomach cramps and bloating.
Macronutrients are the main nutrients of foods that we eat such as carbohydrates, fats and proteins. Each macronutient has their own specific role within the body and with a loss of one macro, you're compromising the roles of the other 2 in the body.
They Taste Good!
Because when have cheat meals ever consisted of fruit and vegetables? ;) Whether it's pizza, pasta or just a slice of cheesy toast - you simply cannot beat a good carb feast!
