My Attempt at a Lifestyle Change

Hello,

I'm a 6' 2'' 245 lbs. male looking to make a lifestyle change regarding my eating habits.  I've worked with my friends and colleagues to develop the following diet, and was wondering what your thoughts were esp. relating to sodium content.  I'm extremely new to this, and feel like where I've gone low in calories, I've upped sodium.

Breakfast:  1/2 container of egg beaters w/ hot Sauce & a 1 slice of double fiber toast with Omega-3 enriched spread.  Coffee.

Lunch:  Tuna fish and 2 tbsps of Fat Free Cottage Chesse on a bed of spinach with an occasional dill pickle. Diet soda.

Dinner:  Can of healthy choice vegetable soup (80 calories/serving) and slice of double fiber toast with cottage cheese. 

I'm doing ~30 minutes of strength (push-ups, leg lifts, etc.) and aerobic (jogging) work-out/day and constantly drinking water.

Thanks in advance for your thoughts.
