I'll admit, I've only just found your weight loss blog (or more appropriately titled, Fitness blog :) ) and I have to admit, this is a really fantastic idea to stay on course. I'll admit, I, too, am on the path to fitness (or regaining it, as being a full time student is taking a lot out of me) but here's something I've found really helps me:
European/Mediterranean style eating. They eat their heaviest meal in the middle of the day with a filling breakfast (oatmeal, some fruit...?), a mid-morning snack if need be, their biggest meal of the day at lunch (plenty of time to digest!), and if necessary, a mid-afternoon snack (a few veggies, a piece of fruit, some of that dark chocolate you like so much?) then one more meal at the end of the day, about 4 hours before bed.
I've experimented a lot with times to eat and how much to eat and when. I read your rant on BMI, and believe me, however long ago that was, I am fully behind you. BMI of 27 isn't terrible, but it's within the overweight limit, certainly. But my waist, thankfully, is nowhere near a danger zone. No, instead, it's all around my hips and thighs. Yay, being a woman? 5'4, 160 pounds, well, that's... certainly not thin. Solid, perhaps a little fuller, but with even weight distribution it's noticeable only when naked.
But back to the point - diet is truly up to the individual. I've experimented with the 'right diet and exercise' and I can't do 3 meals a day. Shoot, I can't even handle 4. I need about 5-6 otherwise I'm starving when it comes to meals and so much for portion control. (*raises hand* I am a foodaholic... for healthy foods). However, I did some research and tried eating 5-6 times a day - smaller meals, except for lunch. My caloric intake for the day stayed right where it needed to be to lose weight (I'm down to 147 from 154 (which took about 6 weeks) after only 3 weeks of doing this), I allow myself a small indulgence (a York peppermint patty - not only is it dark chocolate, but peppermint is an appetite suppressant!) if I get a hankering for something sweet, and I exercise every day.
Whether I go to the gym or not is another story, but I make sure I get exercise every day - for those days that the gym is closed, or it's raining too hard to walk there, or whatever the case may be, I do power yoga - movement, not static. Plus, as a fun class, I'm taking martial arts. Now THAT is a workout for your body!
But despite doing all of those things, until I switched my diet to the one I wrote above, I wasn't really losing any shape or weight. I switched to eating my heavy meal midday, and suddenly I'm losing 2-3 pounds every week. I've lost 1 1/2 inches in my waist, 2 inches in my thighs and my arms have toned up.
So maybe if you find your weight stagnating, try switching up your major meal time and see where it goes! I'll keep up with your blog here though, and hopefully this will help keep me motivated. You're doing a great thing for yourself, and doing it well!
