Ensuring that you are well-nourished before exercising is extremely important for optimal exercise performance. BUT eating the wrong foods before your workout can negatively impact your exercise.
So what foods should you avoid before your workout?
High fat foods: Fat is digested slowly in the body therefore, when it is consumed close to your time of exercise it can negatively impact your workout. High fat foods may make you feel sluggish, full, and bloated.
High fibre foods: High fibre foods have long polysaccharide chains which are not digested easily in the body. Therefore, this leads to gas, cramping, increased bowel movements, and gastrointestinal distress.
Refined sugars: These sugars are found in many white coloured and highly processed foods. For example- white pasta, table sugar, white bread, etc. Refined sugars have a high glycemic index. They cause a drastic increase in your blood glucose quickly after intake and tend to have a low satiety effect. This type of sugar gives you a very short boost of energy and then you become tired shortly after due to an abrupt decline in your blood glucose levels. This abrupt decline in blood glucose also leads to feelings of hunger.
Avoid expensive “pre-workout” supplements: Many pre-workout supplements tend to be high in the refined sugars (always read ingredient labels!)
