9 years out...
Cut out any processed, white, simple carbs from your diet. If you've started eating them again, you'll feel like crap for a week, but then you'll feel tons better. When I get that stuff out of my system, I feel SO much better.
Focus on eating dense proteins. ( Steak, chicken ( skinless ), fish, shrimp, pork and other meats I can't think of, haha ) Weigh and measure your food, and stick to the portion size you were eating when were losing weight. Portion size tends to creep up over the years.
Make sure you get at least 60 g of protein ( but I'd personally go for 80 or 90 most days. ) and make sure you stay hydrated. Try not to drink your calories.
Don't drink with your meals if you've started.
It will take the weight longer to come off this time, but it's totally doable.
Hopefully others will respond and mention steps I'm sure I forgot.
ETA: Log your food into an app like MFP to keep track of your protein, calorie, carb, and sugar intake.
Good luck!
