Q

Main messages from 2020 CPGs for obesity

A

The ’obesity’ field is starting to apologize for the stigma/bias it has caused. Everyone deserves to be treated with respect, dignity and care
* Not all people with higher weights, BMIs or larger body sizes have obesity
* NEW: Obesity is a chronic, progressive disease characterized by abnormal or excessive body fat (adiposity) that impairs health
* BMI should NOT be used at the individual level to diagnose obesity
* Emerging evidence is shifting our understanding and treatment options. Move away from weight, body size or shape to focus on
improving health outcomes. Research community to shift the focus from BMI and weight towards health based outcomes (regardless of weight change)

Q

CPG recommendation

A

Adults living with obesity should receive
individualized medical nutrition therapy
provided by a registered dietitian (when
available) to improve weight outcomes
(body weight, BMI), waist circumference,
glycemic control, established lipid and
blood pressure targets.
* Level 1A, grade A.

Q

5 key steps from CPG

A
  1. Ask permission to offer advice and help treat this disease in an unbiased manner recognizing obesity as a chronic disease.
  2. Assessment of an individual living with obesity, using appropriate measurements, and identifying the root causes, complications and barriers to obesity treatment.
  3. Discussion of the core treatment options (medical nutrition therapy and physical activity) and adjunctive therapies that may be required, including psychological, pharmacologic and surgical interventions.
  4. Agreement with the person living with obesity regarding goals of therapy, focusing mainly on the value that the person derives from health-based interventions.
  5. Engagement by health care providers with the person with obesity in continued follow-up and reassessments, and encouragement of advocacy to improve care for this chronic disease.

Q

Recommendations regarding weight bias for health professionals

A

Healthcare providers should
1. Assess their own attitudes and beliefs regarding obesity and consider how their attitudes and beliefs may influence care delivery
2. Recognize that internalized weight bias (bias towards oneself) in people living with obesity can affect behavioural and health outcomes
3. Avoid using judgmental words, images and practices when working with patients living with obesity.
4. Avoid making assumptions that an ailment or complaint a patient presents with is related to their body weight.

Q

Good versus bad language to use

A

Seek to not be
* Authoritarian “You must not eat these foods”
* Disapproving “You shouldn’t eat that” (red circle on records)
* Demanding “Before you come and see me, fill out this food chart so I can see what’s going wrong”
* Threatening “If you don’t lose weight, you’ll get diabetes”

Seek to be more
* Encouraging “I can see the effort you’re putting in…”
* Empowering “What changes do you feel are needed?”
* Collaborative “Let’s talk together about the different options and see what you think would suit you best”
* “How can I help you achieve your goals? “

Q

Obesity as a chronic relapsing progressive disease process

A
20
Q

Clinical component of the medical diagnosis of obesity

A

candidates for weight-loss therapy can present with either excess adiposity (i.e. anthropometric component) or weight-related complications (i.e. the clinical component)

21
Q

What is included in the science of obesity?

A
  • appetite control - homeostatic, hedonistic
  • energy balance dysregulation
  • obesity paradox - MHO (metabolically healthy obesity)
22
Q

Iceberg of obesity

A

The root causes lie below the surface and need to do more digging to find changes

23
Q

Complex factors affecting weight

A
  • sleep
  • Environment
  • Body composition
  • Genetics
  • Psychological
  • Stress
  • Medications
  • Health conditions
  • Life stage
  • Neuroendocrine

Simplistic: food and activity

24
Q

How might pharmacotherapy impact weight?

A
  • appetite, satiety
  • metabolic rate
  • respiratory or heart rate
  • digestion, gastric emptying rate
  • alertness and cognition

Evidence for the efficacy of a dietary supplement in stimulation of weight loss is absent or inconclusive

25
Q

Use of obesity medications

A

Obesity medication in conjunction with health behaviour changes can help when health behaviour changes have not been effective or sustainable on their own.
* GLP-1 analog → Liraglutide 3 mg (Saxenda®)
* lipase inhibitor → Orlistat (Xenical®)
* opioId receptor antagonist + antidepressant → Naltrexone/bupropion (Contrave®)

Medications (prescription or OTC) not approved for obesity treatment may not be safe or effective and should be avoided.

26
Q

Contraindications to obesity interventions

A
  • New diagnosis or change in medical conditions where treatment could impair or impede treatment of management of that condition
  • Pregnancy or recent post-partum (within 6 months of delivery or lactation)

A
  • patient history
  • Biochemical Data, Medical Tests and Procedures
  • Anthropometric Measurements

  • Food / Nutrition Related History
28
Q

Why gather patient history?

A
  • Helps you understand their lived experience

  • Helps to target treatment and explore supports/providers needed
  • Helps to establish realistic expectations
29
Q

Key processes for gathering patient history

A
  • Active listening: paraphrase, summarize to ensure you understand and validate the patient’s thoughts and experience
  • Show compassion
  • Build trust
  • Acknowledge strengths
  • Explore and reframe misconceptions

* Is your weight impairing your health?
* Peak and lowest weight as adult, last 5 years?
* Pattern? Slow, steady gain; “Yo-yo” with each attempt at loss – what interventions?; Major life event(s) associated with weight change
* Age of onset of excess weight

34
Q

Talking about weight when setting goals

A
  • “When people see a dietitian to help them improve their health and weight, some people have a goal in mind. Do you have a specific weight goal? What weight are you are trying to get to?”
  • “Can you share with me how you set (or the reasons for) that specific weight goal?”
  • “If you were this weight, can you describe to me what your life would be like? (i.e. compared to now - what do you think gets better, what would stay the same and what might get worse?)”
  • “If you were to not able to achieve or stay at this goal weight – what do you expect to happen or not happen?
35
Q

How to gather intervention history

A

Many people have tried different ways to manage their health and weight. I’m interested in learning more about what you have tried, what you liked, what you didn’t, what worked or didn’t work for you? Would it be ok if we talked about what you have tried in the past?
* Look for ideas what may be most helpful now
* Screen for inappropriate methods in past (risk)
* Need referral to other health care provider?

36

  • Edmonton Obesity Staging System (EOSS)
  • Determine targets to measure outcomes
