Drinking diet sodas instead of sugary drinks might help some people lose a little weight for a while, especially if they're already at risk for heart problems. But drinking them for many years might not be safe and could actually cause health problems.

People who drink diet sodas and other artificially sweetened drinks may be more likely to have a stroke, heart disease, or even die sooner — even if they’re not overweight or don’t smoke.

Drinking more diet sodas and other artificially sweetened drinks might raise your chances of dying from any cause, heart problems, or getting type 2 diabetes, according to big studies that tracked people over time.

If you swap sugary drinks like soda for diet drinks with artificial sweeteners, you might lose weight and reduce fat in your body and liver — especially if you’re overweight or obese.

Switching from sugary drinks to diet drinks might help people lose a little weight and body fat, but it doesn't clearly improve blood sugar or heart health markers.

Drinking more sugary drinks like soda is linked to a higher chance of heart problems, partly because it makes you gain weight, but also because it directly messes with your blood sugar, insulin, fats in your blood, and blood pressure.
