4. Fruit Juice (Even Fresh Juice)

Although fruit juice seems healthy, it lacks fiber and delivers concentrated sugar directly into the bloodstream. When consumed on an empty stomach, it can irritate the gut lining and spike insulin levels rapidly. Without fiber to slow sugar absorption, juice acts similarly to a sugary drink.

Morning juice consumption may also increase acidity and bloating, especially in people with sensitive digestion. Over time, it can contribute to blood sugar instability and increased fat storage. Whole fruits are far superior because their fiber supports digestion and gradual energy release.
Healthier alternative: Eat whole fruits or fiber-rich smoothies.
