Welcome to the boards! There's lots of info here and TONS of good support. For me it's nice to have a place to turn and get some instant validation for losing a pound or two or fitting into a new size. Those aren't things I feel comfortable braggin about IRL!
I've lost 50lbs in the last 6 months. Here are some key things that I think made a difference for me...
1) I ordered frozen meals through a company (BistroMD). I know this isn't a possible for everyone because it's expensive ($180/week), but it's made a big difference in how I see portion sizes and the types of food I should be eating. I feel like it retrained me and I'll make better choices once I stop ordering food. It was also easier to avoid fast food and other pitfalls because there was always a meal waiting for me!
2) Even without the food delivery (there have been times where I still made my own food), I've been eating much "cleaner" -- unprocessed foods, LOTS of fruits and veggies.
3) I've kept a food journal of everything I eat (well for 95% of days anyways!) and tracked the calories. I don't keep track of carbs, but I do keep an eye on them. I try to have each meal fall between 45-60g carbs and snacks from 10-15g carbs. I also don't track protein, but I keep an eye on it. I eat protein at every meal. I average around 90g of protein a day which is more than the USDA guidelines, but fits with many recommended weightloss plans. I plan for the calories (1400-1700 a day) and the carb, protein fall into place because I pick healthy foods.
4) I drink LOTS more water, 50-70oz a day, and no more sodas.
5) I eat 3 meals a day and 2-3 snacks.
I've done very little extra exercise. I walked/ran for a couple of weeks, but stopped. It's on list to get started again. I find it more difficult to lose when I'm exercising a lot, but I suppose it would be healthier!
BEst of Luck!!
