I don’t think you’re eating enough fat, as Pex suggested. I would use the ‘regular’ versions of cottage cheese and milk instead of the low fat ones. A little more fat in your diet would likely stimulate your metabolism better. Low fat products are, quite honestly, less healthy than ones without fat taken out.
Other than that, your food choices are fine.
For taste, seasoning changes everything. Get a good cook book, and learn several cooking techniques for variety. Seasoning adds flavor without adding calories. Salt and pepper on everything (use iodized salt, NOT sea salt). I also like turmeric, cumin, cayenne, and a variety of other seasonings.
