How do you other trainers get clients to make small changes in eating habits?
I agree with Danielle.
Assist your clients in developing SMART goals and never forget that if your clients are changing their behaviors self-efficacy in the new behavior will be low.
Keep in mind that you are asking your client to adopt a new behavior that they’ve never engaged in before and that past experience with a behavior is correlated to self-efficacy.
Hope this is of help to you.
