They were taking part in the launch of a new weight management programme to help people in the city's West End, as well as uni workers and students, fight the flab.
The drive, by Reach Pharmacy, is part of Sport and Wellbeing Week, which kicked off on Monday.
Members of the local community can pop along to the chemist, located on the university campus on Hillhead Street, to get their body mass index (BMI) calculated and free weight management advice from the experts.
The pharmacists will help those wanting to lose weight draw up goals and give advice on healthy eating and portion controls.
Each week there will be a weigh-in to monitor results.
The programme, also available in the pharmacy's Argyle Street branch, is part of the battle against obesity in Scotland.
Pharmacist Neeraj Salwan said: "Anyone worried they may be overweight should pop along to Reach Pharmacy to get their BMI calculated.
"This will reveal whether they are within a healthy weight range for their height.
"An essential part of a healthy lifestyle is maintaining your body weight within the range considered normal for your height."
