If you want to lose weight - the simplest thing i can suggest (Coz it is a hugely complex biochemical thing).... Is basically this:
Fast one day (fluids only)
Eat normal the next.
If you reduce your food Intake - after a while your body goes "Oooh - I better conserve energy"... so it slows your metabolism - and makes it even harder to lose weight.
If you keep changing how you eat every 2 - 3 days..... The body doesn't acclimatise.
There is also the 5:2 diet that many have had success with.
And it's actually more a lifetime eating plan than a diet. Which is better 😊
Good luck 👍
