With eDiets, you're able to switch between meal plan platforms freely with no additional cost. To change your plan, simply navigate to your 'My Account' page by clicking on the blue 'My Plans' button on the top right of the eDiets site. From there, you will see a 'Change Plan' button. This will update your subscription to the plan you choose.
Remember, once you change your meal plan, your weekly menu will change to fit your new meal plan. If you have already completed your grocery shopping for the week, you may want to consider waiting until the next week to change your meal plan.
