It's a good plan but why will it work for you? How do you know if it will work for you?
Do you know what your diet actually looks like right now to compare it to?
HelloFresh are good but you do have to be careful; at work, we tested some of their products and by weight, they typically contain more calories than advertised.
Meal replacement products, like shakes, etc. serve a purpose but they're not intended for long term use and whilst there are so many really good options out there, there are double the number of really poor quality options out there too but they're all ultraprocessed and not very good compared to meals with wholefood ingredients. I'll tout batch cooking and meal prep all day long for people who are limited in the amount of time they have available each day over meal replacement products any day.
If I were you, I'd jump on Nutracheck and start logging everything I'm eating and drinking after every meal. Every single thing that passes your lips should be logged (within reason, I don't think there's many calories in chewing a pen lid amongst other non-food things we might put in our mouth... I'm sure there's a joke here somewhere but I'm far too innocent to see it). This will give you a clear picture of the state of your diet right now, how many calories on average your consuming per week etc.
The average woman needs 2000 calories per day to maintain their weight, men need 2500; we'll call these "maintenance calories". There are different factors which will influence this figure but as a rule of thumb... If you're currently eating 2800 calories per day, you need to reduce your portion sizes to achieve the maintenance calories first and develop this new way of eating as a habit engrained into your lifestyle before you attempt a calorie deficit. 2800 calories to 1500 calories is a MASSIVE jump, completely unsustainable. 2800 calories to maintenance calories is a massive drop for women, a lot more manageable for men. So we reduce our intake incrementally until we achieve maintenance calories. Once this has formed as a habit (around 6-12 weeks of strict consistency), then you can start incrementally reducing the amount you eat to achieve your deficit goal of 1500. You might find you're quite happy with the progression of results at 1800 and decide that 1500 is unnecessarily low or that you feel lethargic and irritable at 1700 so 1500 is going to be an absolute nightmare!
The easiest, most sustainable way to lose weight and keep it off is to take small and deliberate but consistent steps towards your goal over a period of time. You have to be as consistent with your decisions that will make you lose weight as you were with your decisions that lead you to gain weight in the first place. You didn't use meal replacement shakes to gain weight... Something to think about. :)
