I can't pinpoint which factor contributed the most, but I continue to do intermittent fasting skipping breakfasts. When I feel like it, I try to fast for 24h, usually 2 to 3 times a month. It really isn't that difficult, it just takes discipline and focus.
Regarding your advice, I'd like to add just a point: drink more water, true, but also try to increase your salt intake. It seems to make a lot of difference in the beginning, alleviating possible side effects.

Edit: Though the video starts off talking about a vegetarian diet, the main talk by Dr. Alan Goldhamer is about fasting, and has nothing to do with one's dietary choices.
Turns out, simply cutting your calorie intake (while generally eating whatever type of food you like) works out fine and has minimal drawbacks. In fact, I felt less "bloated" (I know, that's a health food buzzword but it's kinda real), which more than counter-weighted the lack of comfort food. You also have to get used to the idea that "hunger" is a normal, everyday feeling and not an alarm signal (first world problems, right?). Usually, you can actually still _eat_ whenever you're hungry, anyway, and it even tastes better!
25-50% off is easy. You can eat a full meal, generally, and still be below your 50% daily calorie intake, there's still room for a snack. All supermarket foods have calorie labels now and the rest you can look up online and quickly get a hang for. We all know the worst offenders (chocolate, soft drinks, fried stuff,...) but once you look it up it forces you to face the reality of it. I never wrote down any lists, just a rough, rounded number in the back of my head.
Generally, it was way harder to start than to keep going. After a week or two, it's easy. Lost 10+ kilos that way over the course of a few months (like 4 or 5?), which put me within my personal weight goal.
I don't know if it's the healthiest or most ideal way of going about it, but it's what works best for me.

You then have to have an absence of glucose in your body before you may metabolize your body fat. This doesn't happen often for most people, hence, the obesity epidemic from overconsumption of sugar.
That's the short version. The long, detailed version is available from YouTube, search for Dr. Robert Lustig's videos.
Mine was, in short, reducing isn't so hard if you simply remove the unnecessary. That's it. Speaking for myself, as fit as I might be, I do know I consume unnecessaries.
> But if you think of sugar, etc. as necessary and natural then you're more or less doomed, as you deserve to be.
Which, apart from being wildly unnecessary color commentary, is the equivalent of saying the earth is flat. Sugar is literally one of the core building blocks of aerobic life, which is over 99.9999999% of multicellular organisms.
I have friends who have noticed the same thing, and others who haven't. I'm sure it depends on your metabolism. For anyone not training who hasn't tried time-restriction, it's worth it: if your metabolism works like mine, not having to think at all about food except for ~4 hours of the day is super convenient.
Interesting. Much earlier (teens), I had read a book - I think it was a story about Robin Hood - in which they said that he and his men ate only once or twice a day. I remember wondering at the time how it was possible, how they did not feel hungry, more so since they had active physical lives.
I vaguely recall a recent study that covered this. I believe the theory is that when we're hungry our brains become more focused to aide in our ability to find food. After we've eaten there's not much need to think.
To the greater arguments regarding intermittent fasting: I hate to call on the historical human argument, because it's often abused (e.g. for the raw food diet, paleo diet, etc), but in this case I think it applies because until very, very recently the vast majority of humans spent most of their lives hungry. Hell, we still have parts of our world today where people starve to death (not because of lack of food production, by the way; it's a political issue). It's no surprise, then, that not only can we go without food just fine, but a significant portion of our behaviors and adaptations are built around intermittent fasting.
That isn't to say that intermittent fasting is maximally optimal. It may just be more optimal then how most Americans eat (large meals 3+ times a day, occasional snacks and a sugary beverage throughout the day).
I think the biggest issue we face today is our food culture, particularly in Western societies. Food is the center of every occasion. In Latin derived families you see the habit of constantly forcing food on guests, and both Latin and Southern European cultures are big on forcing their children to eat until their plate is empty.
This made a lot of sense when food and calories wasn't abundant, and there has likely been a lot of selective pressures on those cultures over our recent history. But food is plentiful now. Whereas in the past when forcing children to eat every last speck meant them barely getting enough to eat; today forcing children to eat, eat, eat means making them fat.
Unfortunately I don't think the same selective pressures will work. Being overweight isn't going to stop you from raising a family. So our only two real solutions are to either forcefully change our cultures so that dieting, whatever the diet may be, is the cultural norm, or we apply science to develop foods with lower caloric densities. The latter is, unfortunately, demonized for some godforsaken reason (e.g. artificial sweeteners).

> hunger comes in waves, you'll get to a point where you feel super hungry, it'll usually pass after some time
Matches what the video above talks about "Ghrelin" from 5:03 onwards.
I agree about hunger coming in waves; I'd go 12 hours without even thinking about food, then it's all I could think about for an hour. Probably didn't help that I was still cooking for the family!
There is a lot of evidence to suggest that fasting, and even intermittent fasting, is a good thing (actually, I seem to recall some papers/articles have ended up on HN). Fasting has also been shown to regenerate the immune system[1]
Besides, I have enough body fat to supply calories for a good bit longer than 5 days :)

For those interested, most of the benefits (for me) happened after the 5th day. Thats when the hunger and caffeine withdrawal ended.
I don't know all of the science behind it, but I can honestly say that I never felt better/healthier in my life.
For me it turned out it to be easier to do than I thought. I had a mental barrier in my head that going without a meal or two would put me in some sort of dangerous state where my body couldn't function. Once I realized that wasn't the case I was able to plow through increasingly long periods of time without eating. Things I've noticed:
* being h-angry is a real thing. ;-) Make sure you have a low-stress time window to do the fasting in * drink a lot of water * hunger comes in waves, you'll get to a point where you feel super hungry, it'll usually pass after some time. * maybe it's placebo but I recognize a stronger ability to focus when I'm in the midst of a fasting period * if you get super hungry, just eat. don't beat yourself up over it * i've generally learned to NOT tell people you're fasting, they think you're crazy (immediately they associate it with anorexia, etc) * again, don't forget to drink water
