Experimental: eTRIP smartphone application
Intervention group 1 involves using the eating behaviour trigger-response inhibition program(eTRIP) smartphone application for 10 weeks, where participants will need to take pictures of their food items as part of their food logging and may also engage with app-based activities to build self-regulatory skills in sticking to their weight loss plans. Additionally, participants will also apply a continuous glucose monitoring (CGM) sensor on their arm and taught how to scan the CGM sensor so that they can monitor their glucose levels for the first 10 days.
