Sorry, but this is complete rubbish. You can gain muscle and lose overall weight- and by definition fat- very easily, just look at some of the success stories on the Stronglifts forum from people who started off being overweight.
I personally, aside from a scant few months in my early 20s when I did sod all and got fed square meals by my mum every day, have never been overweight. Doing stronglifts has cut my bodyfat by 1-2% while gaining me at least a stone of muscle. I was slim before I did stronglifts, I was only interested in gaining weight and strength.
Cut and bulk is a bodybuilding technique. I'm not a bodybuilder. Your body will be more willing to gain muscle if it's not staved of calories. But if you're working out with a bodyfat ratio of 25% to start with, then by definition your body is not starved of calories, and it will be quite happy to sacrifice fat for muscle.
I'd rephrase that to 'eat lots of protein'. No protein = no muscle growth. After that it comes down to simple thermodynamics- if you consume more energy than you burn you will gain weight, and vice versa.
I have never ever done a cut at all, and I'm not so far from the physique of a Men's Health cover model now. BMI 25.5, waist 32" etc.....and a deadlift of 170kg, more than twice my bodyweight.
Sorry to repeat myself, but that's just
utterly wrong on so many levels. The human body gladly gains muscle while shedding fat if it's being worked. Muscles burn energy just existing, so gaining muscle through strength training is a superb way of losing fat.
TBH Lucio, all I have to say is <deleted - unnecessary comment> get lifting weights. I saw amazing gains last year, then flaked out for five months, then saw pretty impressive gains again. I've been proper lifting now for about 8 months in total and I can now deadlift 170KG (well over twice my own bodyweight) and squat 130kg.
In my experience most men don't want to be skinny- they want to be muscular. You can get muscular by being a hod carrier or a scaffolder, but I reckon most of us are better off lifting weights.
