Since most fruits contain high levels of sugar, consuming only fruit juice without balancing it with other foods can cause drastic fluctuations in blood sugar levels, which is detrimental to blood sugar control. For those aiming to lose weight by consuming freshly squeezed fruit juice, juices from high-sugar fruits not only fail to aid weight loss but may lead to obesity.
