KIDSCutting sugary drinks reduces childhood obesity
Is this true? Make your call, then see what the science says.
Short answer: It depends. The evidence is mixed.
Kids who drink more sugary drinks tend to have higher body weight, and Australian health advice is to limit them. But most studies only show a link, so cutting them is not proven on its own to reduce childhood obesity.
AI-generated summary of the research cited · not reviewed by a medical professional · checked 13 October 2026 · How we checkWhat the research found
A 2022 review pooled 33 observational studies with 121,282 children and teens. High sugary drink intake was linked to a higher BMI, bigger waist and more body fat. These studies show a link only. The authors called for more large, long-term studies.
A 2022 World Health Organization-commissioned review looked at unhealthy foods and drinks in young children. Almost all the studies (59 of 60) were observational, and the evidence was rated low quality. A 2006 review also found a link between sugary drinks and weight gain. It noted one school program where children drank fewer soft drinks and fewer became overweight or obese after 12 months.
Australian health guidance says the evidence on changes in sugar intake and body weight in children is of moderate quality. It still advises limiting soft drinks and offering water instead. Extra energy from any source, without enough activity, can lead to excess weight.
What it doesn’t mean
- Cutting sugary drinks is a sensible step, but it is unlikely to fix weight on its own. Overall food, activity and family habits all matter.
- Most evidence shows a link, not proof that cutting drinks causes weight loss. Results for individual children will vary.
- If you are worried about your child's weight or growth, talk to your GP or child health nurse before making big changes.
