Hi here, I was hoping someone could look over my eating days and tell me if im starting off alright,
I have made major changed from my old lifestyle, and i no longer eat red meat,, just turkey, chicken, and ground turkey and chicken, and some fish, and tuna,

I have been trying really hard to make my calorie intake everydy, but i never get there, im always too full to eat more, calso recovering from years of eating disorder abuse so i understand this is probably a huge factor as well,

Could someone tell me what a healthy calorie breakfast lunch a dinner should be ,
my breakfasts usually are under 300, and under 200 even, lunches are usually small, but not always, and dinners i never know how big or small to go on calories, im told 500 cals for dinner is a good dinner.

just looking for some advice,
Thanks so much.

Steph
