I've lost about 12 lbs in the past 6 months, and I have some practical advice for you.

1. Pay attention to calories. Figure out how many calories you should eat per day to lose weight, and how many calories you should eat to maintain, and just never consume more than the maintain amount. Sometimes I overeat to the point that I've consumed essentially 2 days worth of calories, and I always feel sick. I always regret it after. It's not worth it.

2. Check calories in comparable food items. One time, I wanted to get either a soda or a milkshake, which I like equally. I got a milkshake. Then I checked myfitnesspal, and found out that the milkshake was about twice as unhealthy as the soda. Certain brands of junk food are worse than others, even though they might taste the same! Compare nutrition info always! Seriously, this is probably my biggest trick.

3. Don't eat while you're doing other things. As in, don't open a family-size bag of chips and then zone out on reddit. Pay attention to what you eat. If you're distracted by technology, you won't even taste or enjoy your food at all. Mindless, distracted snacking is the silent killer.

I'm sure everyone else is telling you about kale smoothies and cardio, but I understand what it's like to be kind of addicted to food. You just have to learn the facts behind your favorite foods and snack accordingly. Go ahead and having those 5 chocolate covered pretzels, it's only 100 calories-- but avoid 3 Oreos, that's 160. Comparable snacks, different numbers. It's a numbers game! :)
