I did the intermittent fasting thing for about a month but it's not for me. I'm a shift worker so it just doesn't work out. Exercise routines are also an issue. I work an odd schedule. 12 hour shifts on a 4 week rotation. 2 days on, 2 days off, 3 days on, 2 days off, 3 days on, 2 days off then switch to nights. 2 nights on, 2 days off, 3 nights on, 7 days off. Repeat.
I work out on my days off and either hike, swim, or lift weights. Not enough time to get in an effective workout during my work days as I eat up about 15.5 hours between commuting, work, and attending to basic needs like cooking, cleaning, hygiene, chores, etc. Fortunately, my work usually sees me walking around 8-10 KM per shift so at least I'm not sedentary.
My diet is approx 80% fat, 15% protein, 5% complex carbs. I don't eat any processed carbs or anything with added sugars. Started out at 263 lbs. Down to 223 right now but I've hit a plateau and the high LDL cholesterol numbers are a concern.
I've read up a lot on the keto/cholesterol thing but I'm what's known as a hyper-responder so a lot of the info doesn't apply to me.
