no or lite mayo, -100, 300 calories of dairy instead of 600 (3x~100 kcal servings)... that could be 2x8oz skim milk (160 kcal total) and 1x no-fat yogurt cup (100 kcal), that would take another 340 off.
right there is 440 kcal!
you also forgot to add the 1.2x multiplier to your BMR for a normal day of little to no activity. if you do *extensive* walking or any exercise on top of that, then add that number on top. so your calorise used would be ~1100x1.2=1320, +345 eliptical, +250 - a bit less than 2 hours of walking, meaning total used is over 1900. BMR alone is like... how many calories you'd use if you were in a coma.
so my suggestion: cut out the protein bar in the morning since you have the turkey and mackerel, move the (no-fat!) yogurt to breakfast, no mayo, then you can have either 2 cups of (no fat) milk at lunch or 1 at lunch and 1 at dinner. that will help balance out the meals a bit more and would shave you down to 1450 for a 450 calorie deficit, which is pretty good for long term weight loss.
nice work! im impressed with how well you documented everything. if you keep this up i think you will be happy with your progress
