Hey there You should be eating your TDEE for around 8 weeks. There are some people who decide to do it for a shorter period of time, but normally it takes around 8 weeks. It really is up to you. If you think your metabolism is not that bad, you can do it for 4-6 weeks, and if you feel your metabolism is OFF! then you should probably do it for 8 weeks, especially if you've been bulimic, anorexic, or have taken your body to other extremes. I guess it's all about understanding and "listening" to your body.

In terms of food you should simply eat clean. Try to stay away from processed food, high fat, empty calories food. Go for fruits, veggies, whole wheat products, lean meats, etc.

Yes! It can feel like a bunch of food, especially because healthy food are normally not so high in calories, compared to other kinds of food. Just try to eat every three hours with 6 or 7 meals a day, and you'll be fine.

I also noticed in your diary that you are still eating the percentage of macro nutrients set by MFP, so try to go to your goals and customize them. Try to eat 40% of carbs, 30% of protein and 30% of fat, also eating 30 gr of fiber
