Pills dont work
I have watched my mother struggle with obesity my entire life. She has done every diet and plan practically imagineable. Her doctor's have over the last 2 years (3 years ago she was diagnosed with type 2 diabetes) put her on several different prescribed medications to help curb eating, shut off brain functions relating to hunger, etc. to absolutely no avail.
The only time my mother has ever successfully lost weight and earned a healthier lifestyle was when she completely, and i mean completely, revamped her diet and excersized consistently.
I am in the same boat pretty much. 5'11 was 234.8 pounds at the end of April '09. I took a good look at it, and yeah, it was my lifestyle and my diet.
You can already acknowledge that your diet sucks which is the first step I made. From there its a matter of changing the foods you eat, which I find is stupid hard to be honest. All the good things for you (aside from raw fruit and veggies) are a pain in the ass to prepare in my opinion. (ordering pizza = 20minute wait, making a healthy pizza = a hella long time).
Making sure you are expending more calories than you are intaking was huge for me. Finding out just how many calories are in some of the things you consume might be enough. For me it was finding out that an Extra Large English Toffee Cappuccino from Tim Hortons boasted something retarded like 400+ calories. And I would drink 3 of em a day. So instead of going before work, on my coffee break and again after work I instead take a bottle of water. ON top of the -1200 calories I save $6.57 a day not including the gas for getting there.
What I have been doing is going through what foods I like and what foods I eat out of convenience. I make sure on days Im eating something I want to eat (taco's as an example) that I consume lighter calorie meals before hand so I dont consume more calories than I burn throughout the day. Essentially I have completely removed foods of convenience from my life (drive through or take out, packaged crap like chips, fatty snack bars, etc.) and replaced them with thigns that are more benificial like veggie plates with 1tbsp of dressing. What works for me to actually CONSUME the veggies (instead of lettin them sit in my fridge like i used to) is to prepare them when you get them home. Ill buy a head of cauliflower, broccoli, some radishes, etc. and get em home, dice em all and wash them up then put them in containers with water so they become "convenient" to eat. This works really well for me because they are so available and for me when I started not eating so much of the heavier foods (baked spaghetti, taco's, lasagna, pizza, etc.) I was hungrier more often. A light quick fix is better than a heavy fix.
Hope something in this mess helps! Good luck!
