Should I go on a diet!?!

Note: picture taken when I weighed 140 lbs.

So a lot has been going on since my last post not because I have been living some crazy acidic lifestyle, but rather because my last post was awhile ago. So on Thursday my bike was built up enough to ride so I went for a ride with a few friends both of which were exhausted to the point of throwing up, but I was just fine I might have been breathing slightly harder but I was completely fine. I want to say two factors caused my friends to be so out of breath A.) They were on freewheel bikes which are a bitch to ride (heavy, unresponsive, just all out crappy) and B.) One of my friends hadn't ridden a bike in awhile. Well going into Thursday night there was a cycling party most of the bikes were fixed gear bikes my friend was on his mountain bike so that is why I say "cycling" party instead of a fixed gear party plus there could have been a few a freewheels in there as well. I have NEVER seen soo many fixed gear bikes in one house it was lovely. And to make the night even better the keg was Bosco's beer I haven't mentioned this before but I absolutely loveeeee Bosco's beer you have to come down here to get it though since it's brewed in the restaurant/bar and it's super fresh and tasty! So the fact there was bikes and Bosco's overshadow the fact it was largely a sausage fest haha. But I mean I don't even know too many girls outside of Japanese girls who ride bikes so yea. 

Going into friday I was still partying pretty hard so hard in fact that I lost my phone. Then I kept on partying hard on saturday. So I am taking a hiatus for the rest of this month because I also got my credit card bill and I have been partying a bit to hard I spent like $400 or something going out eating and drinking. Yea it isn't pretty :(

So I have been trying to step up my workouts and get ready for my return to Japan! But I weighed myself yesterday after working out and the scale read 144 to my knowledge this is the heaviest I have ever been in my life (although when I was on that chocolate almond binge I could have weighed more). But then I also like to think I am in the best shape of my life so I am not sure if I should scale back on my eating or not. I mean it's not like I am sitting around eating cheeseburgers everyday. I eat healthy about 80% of the time I will eat the occasional muffin or cookie (hey I got a sweet tooth).  So I went here to calculate my Body Mass Index (BMI) and for my height (5'10") and my weight (144 lbs.) I came out with 20.7 . Average for that height and weight is 18.5 - 24.9 so I am average so that is good. But BMI isn't the best measurement of general health so I want to go to the doctor to get my Body fat percentage test, an STD test, and possibly find out my blood type (so I will know when asked this question in Japan). So what do you guys think should I go on a diet and work out more or am being obsessively healthy.
