Basically, cutting weight for me has been a 3 stage crusade. I weighed myself on 26th December and I was about 262lbs iirc. It had gone up in December as I had just started a contract in Belgium and was eating a lot of bread + meat + cheese in the evening, plus not really exercising much. Now I wasn't a complete lardass, there was a decent amount of muscle from a Steve Corino '7 days a month' gym schedule. But I knew things were getting out of hand.
I started the 'Slow Carb Diet' in mid-January (living in Brussels). I was lucky as we had a really good canteen at work which offered a plat du jour with a great selection of serve yourself vegetables and salad. I would bring in my own beans/lentils. You get a cheat day on that diet where you can eat whatever you like, which I very much enjoyed. I dropped at a reasonable pace. I did that for about 3 months. By the end I was about 225lbs, though I hadn't been lifting as hard and some of that would have been muscle loss. I think this is a good diet for those who find the idea of 'no carbs' unconscionable, but in some ways it is actually more limiting than keto due to whey/casein protein not being an option yet having to eat 30g of protein within 30 minutes of waking.
I then went to America of course. My aim in America was not not let it all go to shit. Now I ate a big fucking deep pan pizza within hours of touching down at O'Haire, and had my dogs and italian beef. And I drank a lot of beer. Once I got to New Orleans, I started drinking a lot of sugary tea in a can too. In Athen, GA I ate some big plates. But mostly, I ate big once a day, with maybe a small proteiny snack at some other point. Because I didn't want to eat train food, and didn't trust myself with snacks - I actually fasted during my train rides from Chicago-Seattle-LA (I had bone broth and green drink and chia seeds sometimes, also a little MCT oil); I think this really saved me tbh. I worked out here and there until Athens GA, but mostly I walked around a lot. In Athens GA, I did a lot of gym and also hot yoga - I didn't weigh myself but I certainly didn't look any worse. My Father died (Fuck you Cancer etc) and last week or so in America I probably ate a bit more, then I visited Glasgow and I ate some bad food but lifted hardcore. By the time I got back to London I was 240lbs. To be honest, I was probably in better shape than I was at 225lbs - but my clothes were feeling tight again and I knew my ageing ass had to carry less weight. So I decided it was time to try full keto.
I think I wasn't getting it right at first. I thought it would be okay, if I drank lemon water with a lot of lemons and a 'dribble' of maple syrup. Probably not. After a couple of weeks, I started trying to get really low in terms of daily carbs. There was definitely a hump period, despite me taking in a lot of electrolytes. But I eventually got with it, and 13-14 weeks later I weighed in at 200 yesterday - and that's without significant muscle loss (I'm still a 44inch chest). I could lose a bit more, but I will actually concentrate more on improving my cardio and my lifts for a bit. I do cheat sometimes, but I usually fast afterwards to get back into ketosis. The lack of sugar spikes make calorie control a shit load easier, skipping meals is no longer a trauma. And yes, there's a lot you can't eat - but there's a lot you can. Broccoli with parmesan is good, mayo on everything (within reason) is good, casein protein with heavy cream is good, lard.....don't get me started. I honestly believe keto + cheating + fasting IS a sustainable diet long-term, more sustainable than 'good carb/bad carb' diets (South Beach was designed for people with cardiac issues who couldn't do Atkins because of the saturated fats). I keep stevia in my kitchen, but I rarely feel the need to use it.
I recommend checking out Siim Land and Cole 'Stop Eating, Fatty!' Robinson on YouTube. The latter is hilarious. There's a video where he eats only McDonalds for 30 days, but because he skips the fries (he eats the buns) and only eats once a day (one day he eats twice as much and then fasts for 48 hours lol), he fares a helluva lot differently from Morgan Spurlock - this chimes with my own experience.
Keto isn't for everyone, but it's the best diet for some people no doubt about it.
