Let's Talk About Obesity

Obesity is a chronic disease: Recognized by the World Health Organization and Canadian Medical Association and defined as a prevalent, complex, progressive and relapsing chronic disease, characterized by abnormal or excessive body fat that impairs health.

Obesity is not simple: How an individual develops obesity and how they will respond to interventions involves a complex interaction of generic, biological, environmental and behavioural factors. Simple approaches will not solve complex problems.

The Three Pillars of Obesity Management that Support Nutrition and Activity

Psychological Intervention

  • Implement multicomponent behaviour modification
  • Manage sleep, time and stress
  • Cognitive behaviour therapy and/or acceptance and commitment therapy should be provided for patients if appropriate

Pharmacological Therapy

  • Liraglutide
  • Naltrexone/Bupropion (in a combination tablet)
  • Orlistat
  • Semaglutide

Bariatric Surgery

  • Sleeve gastrectomy
  • Roux-en-Y gastric bypass
  • Biliopancreatic diversion with/without duodenal switch

Importance of Physical Activity

Physical Activity improves a wide range of health benefits without losing any weight, including:

  • Quality of Life
  • Depression/Anxiety
  • Body Image
  • Mobility
  • Blood Pressure
  • Blood Sugars
  • Fat Tissue on the liver and heart (visceral and ectopic fat)

Weight loss should not be the goal of physical activity.


Goals for physical activity are:

  • To improve breathing fitness (not feeling winded or out of breath
  • To have better mobility
  • To feel stronger
  • To maintain or build muscle

Medical Nutrition Therapy

MNT is used in managing chronic diseases and focuses on nutrition assessment, diagnostics, therapy and counselling.

MNT should:

A. be personalized and meet individual values, preferences, and treatment goals to promote long term adherence

B. be administered by a registered dietitian to improve weight-related and health outcomes
