#1 YOU MAY HAVE LESS ENERGY
The keto diet involves eating a very small amount of carbs and very high amounts of fat. Following the keto diet may cut out processed sweets and starches, they also eliminate or severely restrict nutrient-dense simple carbohydrates. Such as fruit and low-fat dairy products as well as whole grains and legumes. This is one reason why keto diet is not recommended for overall health, wellness or long-term weight loss.
For those who are active in particular, missing out on high-quality carbohydrates can have some less-than-ideal repercussions. Carbohydrates are the best fuel for the body, following a ketogenic diet can result in low energy levels. That might be less energy during your workouts, and possibly even less motivation to get to the gym in the first place. Having this lack of energy also leaves you prone to injury.
