Obviously I don’t know anything about you beyond what you’ve posted here but 35 kg in six months seems like a way too ambitious goal for anyone, one that is likely to fail and make you feel miserable in a number of ways.
If you’re very overweight, 1 kg per week is quite possible for a limited time, but after a couple of months I would recommend that you instead aim for 0,5 kg/week, otherwise you risk losing too much muscle mass. In turn, that will make it more likely that you gain the weight back once the diet is over.
In conclusion, start with a deficit of 1000 kcal/day for the first month and keep it up for another month if you feel good. After that, at the latest, adjust the deficit to 500 kcal/day and keep that up for as long as it takes. Listen to both your body and your mind and allow yourself to eat for maintenance for a week now and then if it’s needed.
Huel has a very good macro nutrient ratio, but when on a deficit as large as 1000 kcal/day, you may actually need more protein than that to not lose muscle mass. Perhaps one meal a day could be cod or lean chicken breast with spinach, broccoli, bell peppers, tomatoes etc?
Working out with weights is necessary to keep as much muscle mass as possible. Preferably twice a week, at least.
