What ever works for you but calories in & calories out are fairly important losing weight, I’m no expert & can only go with my personal experience, but I’ve been using Huel for about 4 months now & have lost around 3 stone.
I wear an activity tracker on my wrist to count my steps & record sleep, I also use a couple of free smartphone apps to measure converted exercise to calories burnt & record what I’ve eaten / calories in.
These are my normal meals.
Day shift I have
3 scoops for breakfast at about 0430
3 scoops for lunch at 1100-1200
3 scoops for snack/dinner at 1600-1700
Then either 3 scoops or proper dinner at about 2130.
Night shift I have
3 scoops at 1700
3 scoops at 2300
3 scoops at 0500-0600
3 scoops at 1130-1330
Days off are normally about the same as night shifts.
I aim for 1750 calories a day to lose 1.5lb a week & then depending on how much exercise I get will determine how many calories I earn back, this can be upto 2500 some days giving me a 4000 calorie intake. But 5000-10,000 steps a day is normal which is about 700 calories.
I’ve probably made it sound complicated but apps make it really easy to stay on top of it.
