There is a great spreadsheet over here: The Mathematical Diet you can input your height, age, weight and how much you want to lose and it gives you a breakdown of how much Huel you’d need every day at each week as you’re losing. I use this but sometimes have food too, so, i reduce my Huel on those days (i know that 100g of Huel is 410 calories and i tend to look for snack or light meals that are around 400 calories).
Hope this helps.
Good luck
