Little advice re fitness and weight loss

[Deleted User 234324]

So I signed up to a gym a few days ago and also gone for a 12 week challenge thing, partly because this past year I've gained back most of the weight I lost previously on a ketogenic diet where I went from 114kg to 82kg, I'm now back to 107kg having gone back to eating normal foods (not always clean I would admit).

Anyway on of the things the PT asked for was my blood type, at first I was confused as to why that would matter, but apparently it does o_O

I'm O+ which apparently means I should be on low carb, high fat food, aka ketogenic as I was originally, anyone else come across this?

Blood-type nutrition is a load of tosh.

Calorie balance is king for weight loss/gain/maintenance, fat/carb ratios will depend on your food preferences, activity level and what sort of training you do. There's nothing magical about ketogenic diets either - when protein is matched in two diets of the same caloric deficit other than a slight difference in water weight there's no difference between low and moderate carb intake.

I find high protein food very satiating, which lets me keep the calories down without getting too hungry. O+ too (if it makes much difference, which I doubt).

I've gradually lost about 3.5 stone over 2 years, after deciding to go for something I thought I could maintain indefinitely. I went for high protein, calorie controlled with no particular restriction on other macronutrients (but after getting in sufficiently high protein you have to be picky with what else you eat with the calorie restriction). I set the calories based on the Katch McArdle equation for getting BMR ( http://www.calculatorpro.com/calculator/katch-mcardle-bmr-calculator/ ) with an estimation of lean body mass to feed into it and a moderate calorie deficit targeted at losing less than a pound a week.

At weekends all restrictions are off but I think I gradually picked up bad habits and went for too much sugary stuff. The weight loss stalled but it didn't go back on (as it had done previously). Recently I switched to mostly unrestricted but cleaner food at weekends, which seems to work better.

Previously, like you, I'd gone very low carb (probably ketogenic but not systematically so) and lost quite a lot of weight in a short time but I found it boring and couldn't keep it up. Hence the weight had gone back on. What I'm doing now I can probably keep up indefinitely with some minor tweaking if and when I get to where I want to be.

I've tried to stay fairly consistent exercise wise. I get in some resistance training most days (bodyweight exercises and lifting whatever's to hand allows me to do this without spending loads of time at the gym) and maybe 3 quite intensive cardio sessions a week.
