Alright, buddy, this is where I have to call bullshit on just about everything in that post of yours but it's for your own damn good.
First, about losing your mentals. You seemed to lose motivation in your weight loss before that ebook thing if you look back at your previous posts. And as I recall, you've been mostly non-productive for over a decade so why now with all the emo stuff? And now you point to applying for a shit job watching after the old and feeble and say the pay is ok at possibly $45 per hour? OK pay? Please, I know of nobody who has made near that amount doing that type stuff. With the slightest bit of OT you'd be talking 100K a year. IDK, maybe Australia is the real land of opportunity but sounds a ton excessive for that type work. I know it's the thing to do to greatly exaggerate one's earnings or even potential earnings on MBs but let's keep it more real, can we?
Now, let's get back to the weight loss thing. You say you know what you're doing and have had success but you don't and you haven't. You were stalling and losing motivation throughout and seeing as you wanted to go from 300 lbs to 200 lbs, losing 30 or so pounds in 5 months is nothing. Being 100 pounds overweight, that first 30 or 40 pounds should melt off quick as you please with the slightest bit of effort. Now looks like you've been gaining weight again so it was nothing you could sustain anyway. You say you you were eating 6-9 meals a day but not only is that very stupid but from your previous posts it seems quite inaccurate as well. In the posts in which you alluded to what you were eating, it was 5-6 meals a day and much more like 1 meal and 4-5 light snacks. You definitely had a calorie deficit going on but never giving your body a break or need to call on all that excess of fat reserve you have.
Back to intermittent fasting and, again, I only push it cause I have just had great success with it. There is more to the concept of IF than just losing weight. When you sleep, your body takes this opportunity of you not stuffing your face and uses it to regenerate and do great things such as produce HGH. As soon as you wake and stuff your face first thing, it stops doing this but if you held off eating for many more hours, it would use that extra time to continue what it was doing while you were sleeping. Obviously it's highly beneficial for us older peeps to afford our bodies more time to produce HGH, which encourages muscle growth and the burning off of fat. I really think you should give IF a try and I'll tell you why.
Look at the lame excuses you've been making during your endeavor to drop 100 pounds of lard. For one thing, I have no doubt your frame is a tight fit through a doorway while lugging around that excess weight. And, as already mentioned, while your workouts seemed rigorous enough, you struggled to stay motivated as most people would especially with the little amount of sleep and aches and pains you say you have. As for as using your age as an excuse, you can shut up about that cause I just told you how I lost 30 pounds in 4-5 weeks (now 35 lbs) and it was easier than I could have possibly imagined and I'm older than you. You also complained about the cold being a deterrent. I hate the cold more than anyone and can tell you it will never get in the way of getting fast results from intermittent fasting. In fact, cold therapy is another method people have used successfully to lose weight. By taking an ice cold shower 5 minutes a day, people have lost 5-6 pounds per week.... but I digress. Let's stay with Intermittent Fasting which, in itself, makes every excuse you've made a non-factor. You won't need those excuses anymore. With intermittent fasting, you need do nothing but stop feeding your face every few hours. And you'll see it has other benefits too. Maybe reduce some of those aches and pains and/or help you sleep better.
Don't really know how overweight you are but just going on the fact you initially wanted to lose 100 pounds and write an ebook about how you lost 100 pounds in 1 year. I think you can forget about that too cause there have been plenty who have lost 100 pounds much quicker than that and already wrote the books. Also, I know, speaking for myself, while I consider about 200 lbs to be optimal for me, if I was to look up what my weight should be at 6' even, it would probably say around 170 lbs which I know would be ridiculously low for me and leave me looking like no more than just skin and bones. Right now, I'm at 195 or was right after I ate 4 fried eggs last night at 11PM. I haven't eaten since but if I was remotely hungry I would eat right now cause I don't want to go any lower. I'll just have a bigger dinner though cause I don't feel like eating now. As I've said I've dropped weight before and get to this weight virtually every year but this time, with intermittent fasting, it feels so very different. In the past when I've gone as low as 195, I'd look gaunt and many people would even comment saying that. This time, I don't look gaunt at all and feel so much stronger. The only place it looks like I've lost weight is in the stomach area. I'm not a health nut either and I don't eat the best stuff and never count calories but what I did do was eat more of the food, I think is good, instead of the food I know is just empty calories. Depending on who you listen to, they might say some of the food you think is good is actually bad but I don't listen to that either. If it's crap food and just empty calories, we all know it so no need to overthink it past that. My main staples during the weight loss were chicken breasts, steak, eggs, sweet potatoes, rice, spinach, broccoli and still had me some peanut butter and jelly sandwiches.
