The only way to measure correctly is to use body fat calipers.
I,ve been working out for years and know exactly how to drop weight without losing muscle.
Its not easy and take's a lot of will power.....
I,m 6' 1" and started my 12 week cut about 4 weeks ago now.
Started at 16 stone 4lbs with 28% body fat (the beers and crap food had taken its tole over the last year)
working out 6 times a week (got my own gym in my workshop at the bottom of the garden) and eating 6 small meals a day 40% protein 40% carbs 20% fats.
I,m now at 15 stone 5 lbs and 13.63% body fat.
Abs come in at around 10%.
I,ve been down to 5.8% before.
The workouts are killers as every 2 weeks I drop 150 calories and up the cardio by 10 minutes.
Worth all the effort though as you feel amazing with mega high energy levels.
about 9 weeks in I start to add the calories back in.
Give it ago anyone can do it if your strong willed.
