Yeah, we're a fun bunch here.

Tuna is a great source of non red meat protein. But the real key to weightloss is a reduction in calories, not drastic, but moderate and an increase in exercise.
This can be as moderate as a walk around the block and then maybe building up the number of laps each week. And I just have to have sauces and flavour in my food! :D (They often aren't high in calories).

Just being more active can help too. :D

That Superman coin looks awesome. Congrats!
