Another vote for meal prepping over Herbalife. My SIL and her parents did Herbalife, lost weight, and gained it all back, I'm pretty sure. I don't think it really taught them anything, and the ingredients don't seem to be the healthiest.

If you have time on the weekends, you can make foods you like for the meals where you tend to have the least time, and freeze them. For me, it's breakfast. I need a good breakfast to get me off on the right foot. I have found that, if I don't have a solid breakfast, I will eat everything I see later in the day.

To that point, I will spend a couple hours on Sundays making things like breakfast tacos or banana pancakes, etc, and then separating them into servings, and freezing. It makes it a breeze during the week and keeps me on track.

There are several sites that I love, but Oh She Glows may be my favorite. While I'm not vegan, her recipes are practical, easy, and the majority don't include disgusting items like tofu. Copy those recipes into the recipe builder on this site, and you'll have it available in the future.

I always get all my food ready the day before I go back to work, and some things are always the same while other things always change.
For me, the constants are portioning out little containers of protein powder for my breakfast (I currently use Orgain vanilla protein powder from Sam's Club, which I like to mix with Oikos Triple Zero greek yogurt), hard-boiled eggs, tuna made up the way my husband likes it, homemade jerky, and salads for my lunches. What changes up is usually some kind of casserole or low-carb dish I can spread out into several meals, as I also feed my husband the same things. I really like the recipes from BudgetBytes, but there are several good sites out there - most of my recipes come from Pinterest, which you can search by any kind of category you want. Personal favorites include homemade pizza, jalapeno popper chicken, bacon cheeseburger casserole, chili, and quesadillas. Meal prepping is really the only way we can stay in budget, and I can control my calorie intake much easier that way - eating variations of the same thing (at least during the days that I work), make it easier for me, as my job is very sedentary, leaving a lot less leeway. On my days at home, I can eat a much more diverse diet as I am significantly more active.
I usually spend around an hour, maybe an hour and a half making enough food for three days, but that is all three meals plus snacks for both my husband and myself, as I work in two-day blocks with days off in-between.
My diary is open if you wanted to take a peek - you can tell which days I work!

Definitely meal prepping. It doesn't have to be complicated stuff. Just eat nutritious food, at a deficit. Move more. Save your money.

I think meal prepping is just planning ahead so ingredients are on hand and maybe making some things (like lunches or some quick dinners if you know you will need them) are available. I find that helpful, although I don't really make it into a thing.

Part of what I mean by that is that I don't find it useful to focus on actual meal plans or recipes. I buy things that I know I will need for the week (basically the meats I plan to use, and a lot of vegetables, focusing on what's in season). Lots of things are just staples, like olive oil, dried pasta if you use it, canned beans and tomatoes, stuff like that (spices, of course).

I have a pretty standard breakfast (it involves eggs plus whatever vegetables I have on hand always, so I always make sure I have those things). I often prep lunch ahead or pack it with dinner stuff when cooking dinner. For dinners I will have taken the meat/fish I plan to eat of of the freezer or otherwise have it in the refrigerator ready to go (unless I'm having eggs or tofu/lentils or have made some bean based dish ahead, as beans often take longer -- usually I do meat/fish, though). I occasionally will do a slow cooker thing for dinner, but more often I use my slow cooker as part of my making lunch ahead process. Anyway, I have the meat/fish ready to go and then make sides usually just based on the vegetables that are available in my refrigerator. This is something I learned to do well when I started getting a CSA box and needed to learn to use up what I had before it went bad and is, IMO, a helpful skill, and I really advise being flexible and not thinking you need to run out to get specific ingredients to fit a specific recipe.

Often if I want to get excited about dinner I will look at recipes for the dish I have in mind (or the meat I'm having or some of the veg I know I have on hand) or else just skim seasonal recipes on a blog I like like 101cookbooks or look up ideas for a particular vegetable in something like Greene on Greens.

More often I just cook pretty simply and get inspired by what I have or something I see or some idea I have and want to try.

Don't know if any of this is helpful, but back when I started cooking more at home (years ago), trying to cook to a specific meal plan would always seem too complicated or too much work, so realizing this lazy way worked as well -- and is every bit as healthy as meals are still centered around protein and vegetables -- helped a lot.

Having super quick ideas in mind like a pasta with shrimp and lots of misc veg with olive oil and pine nuts or a stir fry with lean beef and lots of veg on rice or some such is also easy and perfectly healthy too.

100% meal prep. Don't waste your money on junk like herbalife.
