1,82m not that tall. With 85kg I look skinny :)
The calorie intake was higher before. If we start to count everything we eat we would have a surprise. For example in the morning I eat a 6 eggs omelette with chesse with two leafs of proteic bread(very low on carbs and very high on protein, but more calories). At noon a kefir or a proteic quark with chicken breast salad. At dinner a starter(if I eat with clients) and a stake with mushrooms on the side. If there is drinking involved a beer(1Liter) or a glass of wine. This are easy 3000kcal. I see that I lose fat but not very fast.
You must have a great genetic baggage then, if you look skinny at 85 kilos. I'm 1.83 and my nominal weight is around 75, meaning where I tend to feel best - I'm under it now, I'm at 74 because I'm experimenting with a low-carb diet for awhile, taking myself lower so I can try to build up some more muscle, though it's much harder for a 31-year old than it is for someone who hasn't passed the 25 mark :) I've always been sensitive to carb intake - which isn't helped by the fact that I love pasta and bread-related products - and this experiment has only confirmed this. I am running at 2000/day calorie, which combined with my workout programe puts me at a calorie deficit.
I'm 34, also I feel best at 85 kg. Same as I, very sensitive to carbs, especially pasta and potatoes. I cut them out. Only bread I eat is a special high proteic bread, which is made out of maximum 7%carbs.
2000/day is I think enough for a desk job, without any activity. For one active it would be a deficit.
