Think Zero Sugar Is Healthier? New Study Says Think Again

Completely cutting sugar out of your diet has become a popular trend among people trying to live healthier lives. But according to new research, eliminating sugar entirely may not be the healthiest choice after all.

A study presented at the ENDO 2026 conference by researchers from the Dasman Diabetes Institute challenges the idea that a zero-sugar diet is ideal. The researchers found that completely avoiding sugar may interfere with the body's normal functions, since it relies on carbohydrates and natural sugars in appropriate amounts to operate efficiently.

According to the findings, carbohydrates and sugars serve as the body's primary and most readily available source of energy, particularly for the brain. When this energy source is severely restricted, it can lead to fatigue, reduced energy levels, and, over time, may negatively affect important bodily functions.

Balance Matters More Than Elimination

The researchers stress that good health is not achieved by completely banning sugar, but by consuming it in moderation.

While excessive amounts of added and highly processed sugars are linked to a variety of health problems, the body still benefits from naturally occurring sugars found in foods such as fruit, as well as from complex carbohydrates like whole grains, legumes, and vegetables, which provide a steady source of energy along with fiber and other essential nutrients.

The takeaway, the researchers say, is that balance, not complete elimination, is the healthier long-term approach.
