Scientific Theories of Obesity
The well-supported explanation of natural phenomena that has been repeatedly tested and supported by evidence.
What is the Scientific Theory?
What is the difference between prospective and retrospective?
Pro: Forward-looking
Retro: Backward-looking
A large enough number of people for results to not be considered chance.
What is "statistical significance"?
18.5-24.9
Knowledge derived from and repeatedly tested in the real world.
Evidence based question
This theory suggests that biological systems actively work to regulate and maintain body weight within a specific/stable range.
What is the Evolution Theory?
Fake or Inactive Treatment
What is a "Placebo"?
Age
Gender
Lifestyle Habits
What characteristics should a control group of people share to ensure accuracy?
Hypertrophy
Increase in the size of fat cells?
Ask a question, develop hypothesis, design study/collect data, analyze results/draw conclusion
Scientific Method (4 steps)
Theory that examines how ancient genetic adaptations interact poorly with environments of food and low activity.
What is the Evolutionary Theory?
Laboratory Experiments
What is the most controlled method of research?
How many markers of High Quality Science are there?
4
(or 6)
Overweight BMI
27.5
Focuses on how nutrients affect gene expression.
Nutrigenomics
Theory that fluctuations in blood glucose influence hunger and satiety.
What is the Glucostatic Theory?
What is the difference between case and clinical studies?
Case: Non-controlled, Individual
Clinical: Control, Group
Used to ensure that results are not caused by the placebo effect.
Why is a "blank" treatment used?
Difference between hypertrophy and hyperplasia?
Hypertrophy: Cell size
Hyperplasia: Cell number
Investigates how genetic differences influence an individuals response to nutrients.
Nutrigenetics
Set Point Theory argues that while biology sets a weight range, these two external factors ultimately influence where a person's weight stabilizes.
What are environmental factors and lifestyle?
Which two trials are "cause and effect"?
Clinical + Intervention
Study where neither the participants nor the researchers know which treatment is being given at any time.
What is a "double blind" study?
Shrinks fat cells
Weight Loss
The ability to evaluate and propose explanations based on evidence.
