Everyone has experienced those mornings when a fresh apple or a bowl of berries seems like a healthier-than-ever recharge, following a full weekend of takeout. One is tempted to believe that the answer to the ideal glow and inexhaustible vitality is to double-dose on the candy of nature. Although a recent study in the American Journal of Clinical Nutrition states that antioxidants are an extremely important factor, a life based entirely on fruit may not be the dream we all aspire to.
Fluctuating Blood Sugar Levels

As fruits are full of natural sugars such as fructose, consuming them solely would result in the drastic peaks and declines of your glucose level. This could make you very weak or tired.
Muscle Mass Could Slowly Begin to Diminish

Proteins are the crucial building blocks of your muscles, and most fruits have virtually none of them. As time goes by, your body may begin to cannibalize its own muscle tissue to perform simple repairs.
Your Digestive System Might Feel Quite Overwhelmed

An enormous amount of fiber in a fruit-only diet would cause bloating or unforeseen bathroom visits. A variety of food groups tends to be essential to your gut and keeps it running well.
Specific Nutrient Deficiencies Could Become a Reality

Minerals such as iron or zinc and important vitamins such as B12 are primarily not found in fruit. The absence of other food groups may later cause such problems as anemia or a weak immune system.
Healthy Fats May Be Missing from Your System

Most fruits contain very minimal fat besides avocados, which are essential to the health of the brain. In their absence, your body may have difficulties in taking up fat-soluble vitamins such as A, D, E, and K.
Your Teeth Could Face a Constant Acid Attack

Natural sugars combined with citric acid in most fruits can also wear your tooth enamel down over time. This may even cause greater sensitivity or even the risk of cavities.
Brain Fog Could Start to Cloud Your Thinking

The brain needs to be fed with a consistent amount of different nutrients and healthy fats to remain sharp. Fruit alone may lead to loss of concentration or inability to remember basic everyday chores.
Bone Density Might Be Negatively Impacted

The fruit kingdom rarely contains any significant amount of calcium, which is important for the strength of skeletons. Veganism (and more specifically, fruitarianism) may pose a unique risk to your long-term bone health.
Hormonal Balance Could Be Thrown Off Course

Cholesterol and healthy fats are needed by your body to make most of the necessary hormones. Getting them out of your diet may cause all sorts of disruptions in the way your internal organs communicate with one another.
Metabolic Rate Could Potentially Slow Down

When your body feels that it is not getting a variety of nutrients, it may go into a defensive mechanism to save energy. This may result in a slowing of the metabolism, and it becomes difficult to lose weight.
The Risk of Developing Fatty Liver May Increase

Taking a lot of fructose in the form of pure fructose without other nutrients to counter it may put a strain on your liver. Other studies indicate that a high consumption of fruit may potentially cause atypical fatty liver problems.
