Questions
Diet plans & nutrition programs: common questions
Should I talk to a doctor before starting a diet plan?
Yes. A doctor or registered dietitian can check whether a plan is suitable for your health, medications and goals. This is especially important if you are pregnant, have diabetes, heart or kidney conditions, or a history of disordered eating.
What is the difference between a coach and a dietitian?
A registered dietitian holds a recognised qualification and can give clinical nutrition advice. Program coaches are usually trained in behaviour change but may not be clinically qualified. Check the credentials each program lists.
Is Jenny Craig still open?
Jenny Craig closed its US centres in 2023. The brand was later bought by Wellful, the parent of Nutrisystem, and relaunched as an online business. Check the current site for what is offered in your area.
Are free diet apps enough?
For many people, a free tracking app is a useful start. Paid tiers add features such as meal plans or coaching. Neither replaces personalised advice from a health professional.
Do meal delivery plans work for vegetarians?
Many services offer vegetarian options, but the range varies by week and region. Check the current menu and filters before subscribing.
