Q

Fitness instructors are often in a position of being asked about weight loss. What is their responsibility? Generally, in the interest of good health:

A
  1. Promote sensible portion control and balanced eating taken from the advice in Canada’s Food Guide.
  2. Promote a sensible balance of activity, exercise and rest.
  3. Discourage excessive exercise as a method of weight loss.
  4. Discourage imbalanced eating plans as a method of weight loss.
  5. Avoid reinforcing the unrealistic expectations promoted in the media. Promote healthy concepts by speaking of “developing a stronger core” rather than “slimming the middle”
  6. Help people realize that spot reduction does not work (or chewing gum would give them thin faces).
  7. Help people realize that they are partly a product of their genetics but do have some leeway in the expression of those genes.
