Eating at night/Cravings before bed

Big time. That's how I ballooned from my college weight of 193 pounds to 330 (now back down to around 240 and still working on it). I doubt more than 10 % of my excess weight was put on before 10 pm.

30 % doesn't sound too bad. I am easily capable - and have done so, hundreds of times - of eating 1,800 calories during the day and then consuming 2,000 or 3,000 calories in half an hour, sometime around midnight. Sounds like a lot of calories but it's super easy. 1 pint of Haagen-Dazs, 1200. Big bag of Doritos and salsa, 2000, or cheddar pretzel chunks, 1400. Couple of candy bars to round things out, 440. Easy. And that's excluding real binge behavior, like ordering a large pizza after all that other stuff is sitting in my stomach - done that plenty of times, too. Even when I'm not binging, I can do a thousand calories in minutes late at night. Bagel with a few ounces of cheese melted on it, 600, add a granola bar and a handful of nuts, bam, 1000.

It took an act of will for me to end that destructive behavior, and you can do it too.

You need a "kitchen is closed" rule in your house, or at least for yourself. Pick a time, any time. 7 pm, 8 pm, I wouldn't go much past 8. When the clock strikes that time, you are done eating until the morning. No exceptions for a month, no excuses. You need to gain confidence that you can break the habit, and the only way you can gain the confidence is by ... actually breaking the habit. In my house, the only "food" consumed after 7 pm is water or unsweetened iced tea. As an habitual, lifelong night-time snacker, I cannot recommend this approach highly enough.

You will need to learn to be a little hungry at night, for a while. Hunger pangs and their associated psychological cravings are weird things. We're conditioned to react to the tiniest little hunger pang with a panic reaction to stuff food in our face, when in reality, hunger pangs are incredibly minor physical sensations, compared to things like the aches and pains we endure constantly. Not only are hunger pangs and cravings minor, they're also temporary. Within one week of implementing a "kitchen is closed" policy in your house, you will discover that hunger pangs dissipate in around 10 minutes and then you will likely either stop having them, or they'll become pretty rare. Not feeding the beast does make it shut up.
