This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counselling, after which.they will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle.
This substudy aims to investigate any changes in physical activity associated with the initial 8-week weight loss intervention.

The investigators aim to describe changes in physical activity associated with a significant weight loss among overweight/obese individuals with knee OA. The investigators will take advantage of the planned trial "Effect of liraglutide on body weight and pain in overweight patients with knee osteoarthritis: A randomised, double blind, placebo-controlled, parallel group, single-centre trial" (the parent trial) in which a significant weight loss is sought achieved over 8 weeks by means of intensive dietary counseling and meal replacement in overweight/obese individuals with knee OA.
The investigators hypothesize that weight loss is associated with a decrease in daily time spent physically inactive.
Physical activity is measured using accelerometer based recordings using a wearable sensor that continuously records physical activity over the entire weight loss program (8 weeks). The sensor is miniaturised, discretely worn on the thigh, and is waterproof. Thus the measurements interfere minimally with the participants daily life.

Intensive dietary intervention
Supervised dietary weight loss program lasting 8 weeks.
Dietary Supplement: Intensive dietary intervention
Participants receive a hypo-caloric formula diet containing 800 to 1,000 kcal/day. The formula diet consists of ready-to-use meal bars and powders to mix with water to make shakes, soups, or porridge. The weight loss programme consists of an 8-week period with full meal replacement by a standard liquid energy intake protocol. To facilitate compliance with the programme, participants will be scheduled for weekly facility-based group sessions with 6-8 participants led by a dietician. The recommendations for daily nutrient intake will be met.
- Change in time spent inactive (minutes) [ Time Frame: week -8 to week 0 ]Physical activity is recorded using an accelerometer based system with a built in algorithm for detection of standardised activities. Inactivity is defined as activities done sitting or lying down.
