35 y/o male losing weight

Hello! The name is Kevin and I'm new to MFP. About 6 weeks ago I started being more active and have lost 20 lbs. Now I'm looking to take it to the next level and hit my goals. Motivation for me sucks, to be honest. But sheer will has kept me going.

Things I don't do:
Smoke (ever)
Drink soda (stopped 6 years ago)
Eat fast food(stopped 9 weeks ago)

Things I do:
Walk an avg of 3 miles/day (for the last 6 weeks, each day I increase by 1/4 - 1/2 a mile)
Eat fresh foods
