Eating & Still Feeling H U N G R Y

I had the same problem, constantly hungry! I too was addicted to fast food. The ONLY way to lose weight and feel full is to eat vegetables. Problem is, I hated veggies and maybe you do too. The trick is to hide them.
My big thing now is wraps. Stuff some shredded chicken breast in a low cal tortilla and add lettuce, onions, mushrooms, whatever you can stomach. A dash or seven of a nice spicy sauce and I guarantee you will feel much fuller than after a burger and fries.

"1) When I eat breakfast I'm always hungry all day long. "

meal timing is bro science. eat as few or as often as needed to keep your hunger in check.
different strokes for different folks. some things work for me, but not you.

try to focus on getting protein and fiber from real food. they are universally filling and satisfying foods.
how much of each varies on what you can handle, and is the best for you.
a general guideline for fiber is 30 g a day. if you eat the oats i suggested, there could be almost half
your fiber right there. depending on your portion. i like a cup (measured dry) possibly more.
it doesn't have to be expensive or difficult to do.
if you're eating less carbs you will need 100g of protein a day. possibly more.
