one meal a day diet

My dad has eaten this way as long as I can remember. he has a banana and pepsi for lunch every single day..and then a massive dinner. Has always made my mom a bit testy. But I can say he has never struggled with his weight. On saturdays he has a big lunch, and on sundays he has a big breakfast..nothing else for the rest of the day. I like giant meals. I often budget out my calories and half of them are spent on dinner. But I also like eating..so I munch all day, and then have a reasonably large dinner.

Well okay if it works good, but I'd still recommend to take BCAAs while fasting

I was going to bring up 18:6, as well. Or what Leangains recommends. I spent some time on the leangains website and saw some of the meals the creator was eating and decided to try it. If you are the kind of person who actually enjoys the Thanksgiving-esque process of eating until you feel stuffed to the gills, it is a great way to cut calories and still stuff yourself.

Everyone has different hunger queues. Some people wake up starving, and some people can have a cup of coffee and go about their day until well into the afternoon. I've always been the later type. I would have a bunch of water (1L or so) upon waking, and maybe a travel mug of black coffee on the way to work. Unless I was boredom snacking, I wouldn't feel hungry all morning, and unless I was going to lunch with friends, I would often skip or delay lunch until well into the afternoon.

With the leangains style of eating, one generally eats a single large meal later in the day. The meals the creator shows are often way over my calorie limit (including whole cheesecakes, etc) because he is also an intense heavy lifting athlete. But trust me, a 1500-2000cal meal, especially a relatively healthy one with veg and meat, is super filling.

A couple racks of ribs, some mixed steamed vegetables with butter. A huge steak, baked potato and veg. Even 1500 calories of takeout pizza is more than enough to make me go "ugh, that's enough..".

If you feel hungry all day waiting your giant meal, this isn't the eating plan for you. For me, I get to stay under my daily, while still stuffing myself with delicious food late in the day.

Edit: This eating plan also means you, generally, work out fasted. This doesn't work for some people, especially some people focused on cardio. For those into heavy lifting, it has the added benefit of increasing cortisol (stress hormone) production during lifting while fasted which can help maximize lifting gains over time.
