that is a poop diet.
you need to know exactly how many cals you are eating everyday.
check out
www.fitday.com, it takes a little bit to get all your foods loaded in there but it will tell you exactly how many grams of protein, and what percentage of your calories come from carbs fat and protein.
for cutting you should have a ratio of something like 50% protein, 30% carbs, 20% fat.
so plug your diet in to fitday, and BE EXACT. see what it comes out as, if it doesn't come out as taht and i'd say you need to be at around 2k cals/day for gradual fat loss, maybe 1750 if you want to cut harder (this is combined with 45 min cardio 4-5x a week)
put most of your carbs towards the early part of the day, protein with every meal, and fats more towards the end (and carbs/protein pwo)
you are 84kg that's 184lbs. i'm guessing you're trying to cut to like 170lbs (77kg)?
if you are taking the winstrol, you can cut harder and faster and worry less about muscle loss, this is one of the primary benefits to using AAS for cutting, getting body fat to even sub-10% levels even in someone with average or slightly poor genetics does not require AAS.
if you are running a 6-wk cycle of winstrol and you are trying to lose 15 pounds bodyfat, this is possible, but your diet and training will have to be perfect, which i can promise you it won't be.
also as far as loose skin, this will probably only make the situation worse (more rapid fat loss) maybe you should give your skin some time to adjust for a few months then start back with the fat loss.
