Am I going to do something with this diet?
What should I change if this is not good for me?

So I am 22, 152lbs, 5’6 height, and about 12% bf.

I am going for 130 lbs, but I am not in any particular hurry.

My daily diet looks something like this (and I don't mind the repetition):

2 peppers/cauliflowers.

2-3 onions (red or brown, it doesn't matter).

200-250 gr of mixed vegetables (stir fried)

400 gr chicken breasts/500 gr fish fillets (usually grilled).

I occasionally throw in 1-2 eggs

1/2 cup of brown rice

I usually have a day or two when I skip this routine, where a little alcohol may creep in, and sometimes fast food.
When I feel the need for sugar I have one cup of yogurt with a little honey added.

Currently following some workout plans that I've found on http://healthyfitnatural.com/, and I think I'm doing alright, so far..
Would classify myself as a beginner, I don't have much experience but I am learning..

So.. I would appreciate any advice, what should I and what should I not change, thanks!
