The site, Eat This Much, helps you save you time and energy while also giving you complete control over the meal planning process. Caloric and macro targets, recipes, grocery lists and a growing food database are all there to help you create your best meal plan.
There are many sites and plans that can help with meal planning. This site is just an example of how technology can help you plan your meals and regulate your food intake. Look around the Internet and find a site that you like. Most aren't difficult to use and, dare I say, can be fun to navigate and experiment with.
P.S. Don't let Thanksgiving get in the way of your diet. Enjoy the holidays!
