<human>: Can you condense the text into a few key points?

I am 5'11" and I started at 226lbs on January 11th this year, I'm now 212lbs. I work from home, so I am able to make losing weight and working out a priority. I was suprised how quick I dropped ~15 pounds, and I want to make sure what I'm doing is "healthy". 

When I setup MyFitnessPal it suggested I have 1700 calories a day. As best I can tell I am coming nothing close to that most days (around ~1200 usually), and I haven't seen any side effects, so I just want to be sure what I'm doing is alright. I eat pretty much the same thing for breakfast/lunch every day.

Roughly what I eat each day:
- Breakfast: 16oz smoothie in the morning (~30% spinach leaf, ~30% frozen fruit, a banana, and a few big spoons of yogurt) [~250 calories]
- Lunch: One salmon filet and a single serve pack of peas or corn [~160 calories]
- Dinner: Lots of variance here, but avoiding bread/pasta [~400 calories]
- Snacks: Atomic Fireballs and Turkey Jerkey [~100 calories max]

Exercise:
- Every other day 30 minutes on the elliptical
- Every day dumbell arm/chest exercises (25lb weights)

Is there any reason I should try to eat more calories than ~1200/day if I'm not starving and don't see any obvious side effects? I used to eat until I was past-full, whereas now I just eat until I'm no longer hungry. I'm excited about the results, and just want to see if I need to mix anything up for the next 15 pounds.

Thanks in advance for any feedback/suggestions!
<bot>: Looking to make sure dropping weight this fast is okay and if I should adjust my diet to be higher than 1200 calories/day going forward.
