LEAN Mass Preservation With Resistance Exercise and Protein During Semaglutide and Tirzepatide Therapy (LEAN-PREP Study)

Status: Recruiting

Location: See location...

Intervention Type: Dietary supplement, Behavioral

Study Type: Interventional

Study Phase: Not Applicable

SUMMARY

The aim of the current study is to determine whether resistance exercise and/or protein intake can preserve lean mass and improve physical function in patients with obesity initiating semaglutide/tirzepatide therapy. To achieve this aim the study will have the following objectives. In people with obesity initiating semaglutide/tirzepatide therapy 1. Form a PPI group to refine the study protocol and establish study materials, 2. Quantify the effects of a pragmatic resistance exercise intervention and/or increasing protein intake on lean mass and physical function during semaglutide/tirzepatide induced weight loss, 3. Establish whether the resistance exercise intervention and/or increasing protein intake has concomitant benefits on glycaemic control, lipids, liver function, quality of life, physical activity and sleep during semaglutide/tirzepatide induced weight loss. The participants will: Begin their weight loss medication, starting at a low dose and then increasing the dose to maximize weight loss. They will be randomly assigned by a computer to ONE of the following groups and will be followed up to 6-months: * Control group * Protein intake group * Muscle strengthening exercise group * Muscle strengthening exercise AND protein intake group.

Treatments

Experimental: Resistance exercise

Participants assigned to the resistance exercise group will be asked to perform exercises 3 times a week for the intervention period. The first 3 sessions of the exercise will be performed under the supervision of a qualified exercise specialist to ensure that the participants are happy with the exercises and are performing them appropriately. These will also be group sessions to encourage participants to build social connections to support them during the intervention. A similar group social session will take place at week 4 and then every 4 weeks of the study to overcome any issues with the exercises and to ensure progression to an appropriate intensity.

Experimental: Protein Intake

The aim of this arm of the intervention is to ensure a protein intake of 1.6g/kg/day, as this was the intake level identified as the level after which no further effect was found on muscle mass in the meta-regression from (Morton et al., 2018). For the initial 2 weeks of the study, investigators will ask participants to consume 2 protein drinks, containing 25g protein (3g leucine), per day - one in the morning and one in the evening. At this stage, investigators won't know the magnitude of reduction of protein intake following initiation of semaglutide/tirzepatide treatment. After 2 weeks, when the first assessment of dietary intake after beginning semaglutide/tirzepatide treatment occurs, the additional protein will be based on the amount required to ensure 1.6g/kg/day with an aim to spread protein evenly across the day and aim for at least 25g protein (3g leucine) per meal or snack.

Experimental: Resistance exercise + protein intake

Participants in this arm will follow the above resistance exercise and protein intake interventions.

No_intervention: Control

Participants assigned to the control group will be asked to maintain their usual exercise habits
