It’s not something that’s possible to comment on even if you ask “what happens if I have 2000kcal of Huel Black Edition a day” because it’s dependant on a lot of different factors.
If you’re looking for a tailored diet plan try a registered nutritionist or dietitian, it’s not something anyone should be offering to you without knowing about you or your medical history.
Please don’t go to PTs unless they are registered nutritionists (very few are). Most PTs either don’t have any qualifications or have taken a low hour nutrition course.
