A lot of studies now would push you towards a more meat centred diet.
Either regards to being full, I believe it’s to do with the fats.
I’ve been trying to get fit and eat better, they say to try and eat 2g of protein per kg if working out a lot. Which is actually a lot harder than you would expect.
I also started eating a lot of Greek yogurt rather than cakes and ice cream( it’s now become my favourite part of the day) I started eating zero fat ones as that what a lot of the influencers and posts would say, then I came across others saying you should have the 5% fat as in that it makes little difference but the fat make you feel more full so your less likely to snack more after.. it has the added bonus of tasting like whipped cream rather than sour cream.
We have always ate a lot better than most we know, the wife being Chinese, me being a chef, one daughter being allergic to a lot and my youngest having been diagnosed with crohns a few years ago ment we only eat fresh cooked food, mainly organic meat, a lot of fish, fruit and veg.
Down side is between the 4 or 5 if you include the dog, as she eats better than some people. We spend an unreal amount on food & I spend way more than most ever would cooking.
Funnily my daughter used to call herself a meatetarian
