The Role of Nutrition in Muscle Function of Bariatric Surgery Patients

The Role of Nutrition in Muscle Function of Bariatric Surgery Patients

Current recommendations for protein intake after bariatric surgery are not based on strong scientific evidence. It remains unclear how much protein should be eaten to minimize muscle loss and preserve the metabolism and function of individuals post-bariatric surgery.

The objective of this study is to analyze the relationships between changes in body composition, nutrition and protein intake, and muscle function after bariatric surgery to further our understanding of the nutritional needs of patients after bariatric surgery.

We intend to recruit around 75 participants, men and women, aged between 18 and 65 years. Participants will be recruited from the Bariatric Surgery Clinic, McGill University Health Center.

Inclusion Criteria:

• Male and female
• Aged 18 to 65 years old
• Undergoing first bariatric surgery (any type)
• Diabetics and non-diabetics
• Non-smokers and non-cannabis consumers

Exclusion Criteria:

• Pregnant and breastfeeding women
• Individuals undergoing second bariatric surgery
• Regular smokers and cannabis consumers
• Current use of Ozempic (or Ozempic-like medication) and anti-psychotic meds
• Limited physical mobility (using walking aids such as canes, walkers, or wheelchairs) and issues with hand resistance
• Kidney disease, non-controlled / unstable hypertension and hypothyroidism, and any metabolic disease other than diabetes
