"Participants who viewed low sugar claims were significantly less likely to intend to compensate for calories in these low sugar products by modifying their food intake or physical activity," the report said.
The study asked 501 Australian women aged 18-35 how they viewed six identical drinks, with half asked about products which claimed to be low-sugar.
Respondents rated those with low-sugar claims as lower in kilojoules, generally healthier, less harmful to their health and more suitable for weight management.
"Our findings demonstrate that low sugar claims on alcohol products can be misleading and (we) support policy options to prohibit such claims on alcohol products and/or counter their effects, for example, via health warning labels and/or mandatory energy labelling," the report said.
Excess alcohol consumption increases the risk of weight gain and chronic diseases such as cancer and heart disease, even if the drink claims to be low in sugar.
"Alcohol is energy dense and alcoholic products are the largest discretionary source of energy in the diets of Australian drinkers (around 16 per cent of daily energy intake; around double the 8 per cent provided by discretionary cakes and muffins)," the report found.
