Description
2 studies reviewed
In plain English

Switching from sugary drinks to drinks with artificial sweeteners does not change body weight, blood sugar levels, insulin resistance, cholesterol levels, or blood pressure in people who participate in randomized controlled trials.

See the scientific wording

Replacing sugar-sweetened beverages with artificially sweetened beverages has no significant effect on body weight, fasting glucose, HbA1c, insulin resistance, lipid profiles, or blood pressure in randomized controlled trials.

Why this might work

When people drink drinks with artificial sweeteners instead of sugary ones, their taste for sweetness doesn't drop much, so they still crave sweet foods. At the same time, since there's no sugar to spike blood glucose, insulin doesn't rise enough to signal the body to store fat or slow down energy use. Without these metabolic signals, body weight and blood sugar stay the same.

What the research says

2 studies
  1. Study: Effects of Sugar‐Sweetened, Artificially Sweetened, and Unsweetened Beverages on Cardiometabolic Risk Factors, Body Composition, and Sweet Taste Preference: A Randomized Controlled Trial

    Switching from sugary drinks to diet drinks didn’t make most people lose or gain weight or change their blood sugar or cholesterol overall — but for people with extra belly fat, it helped them gain less weight than if they kept drinking soda.

  2. Study: Switching from Sugar- to Artificially-Sweetened Beverages: A 12-Week Trial

    This study found that when people switched from sugary drinks to diet drinks with artificial sweeteners, their weight, blood sugar, and cholesterol didn’t change—so swapping them doesn’t seem to help or hurt these health measures in the short term.
