Not fasting... but kinda REALLY fasting

So let me ask this a different way...

Let's say you really worked out a lot very vigorously and burned about 1200 calories a day and you were eating like 1200. (= -2000+/- per day) (with BMR) Would that be bad to go so negative or like "ultrafasting" if they were a lot of great various and healthy calories? like whole grains and salmon and veggies and berries and yogurt and beans and vitamins and stuff?

Yes...No ?

I have read that post 4 times and it still doesnt make sense to me...
are you asking if it is OK to exercise more than you eat, caloriclly?

No, I am saying If I eat 1200 calories of very healthy food + a good multivitamin and lots of water...
but am burning 1200 through exercise + 2000 BMR = 3200 calories burned per day
which equals a caloric deficit of like 2000 per day - is that okay ?
That is kinda what I am doing for weeks on end... I mean I am not hungry and I am getting lots of good food... is this dumb or genius ??

If you are not hungry and you have energy and are loosing weight healthfully then I would say that's ok...I do that too and I feel great.

sounds OK - so long as you dont get burnt out working out that much. I am much do you weigh, and how much weight are you losing/week.

I am not the OP and I do the same thing with the burning more calories than eating...When I Started I weighed about 125 and I am 5'5 and I have lost 6 pounds...I have been doing this for 3 weeks so I will say 2 pounds a week. I change my exercise up a lot so I dont get burnt out or "bored"

I hear ya'
My only problem is sometimes I get weak and have a bad day or two here or there, but I can sustain it for at about 12 days at a stretch so far... and over time it is working despite my occasional imperfections...

What do you do that burns so many calories? I work 45 hrs/week plus have class 2 nights a week for 3 hour time is of the essence for me. I feel lucky to get in 1-2 hours/day, but am able to do more on weekends. Are you doing INTENSE activity in a short amount of time, several bursts of exercise thoughout the day, in the gym or out of the gym?

PP - seriously, I have to run for 2.5 hours to burn 1200 calories!

I have been getting into better and better shape for a year and a half and increaseing intensity -
In the morning I lift weights like a psycho for 30 mins and then run 4 miles or so
At lunch I do the eliptical maxed out resistance as fast as I can make it go for 35 mins then run a mile and lift a little more...
I figure that is around 1200. I know +/- but still ballpark.

I just basically want to know if the basic advice of like:

BMR 2000 + exercise 500 = 2500 burned
therefore you should eat 2300 is really just flawed

I do
BMR 2000 + exercise 1200 = 3200 burned
therefore I eat 1200 (healthy various nutrient dense) calories

and whammo I lose lots of weight but am still getting my fat and calories and fiber and nutrients and vitamins and whatnot...

anything wrong with this ? - cause it seems better than the old school !approach.

burning max calories in an hour

I've been able to burn 600 calories per hour doing X-C skiing (mediium level), and between 500-600 per hour in advanced step aerobic class (with one risor - with no risor - just step onlyI got about 475 ph.) or cardio kick boxing. I don't think I could ever do more than that per hour. Most exercises I do, (eliptical and weights) do less.

As a 6' male your basal metabolic rate should require you to consume a net total of about 2000 cals to maintain a "healthy" weight...I'm not sure if you're going for a chic and lean look (like a distance runner's body) but I would imagine that to be the case?
I can tell you that at 1200 cals plus daily exercise you're not consuming enough to build additional lean muscle- and the weakness you feel is a symptom of that. It sounds like you're eating a great diet though, maybe just upping the cals by about 500-600 would help you have more energy and overall drive to maintain this over the very long haul.
Good health and best wishes!

Yeah you make a very good point, CJ. You're a male, OP, and on top of that, you live a very very active lifestyle. You need to increase those calories to get the benefits of lifting weights. I'm a small female, yet I could never go a day on 1200! I'd feel so deprived (yes, veggies and smoothies fill you up to those who will point out how much produce you can eat but I like variety...and carbs!). When I eat 1700 calories per day (including moderate exercise), I lose about a pound per week. Plus, I don't have a lot to lose.

I hear you CJ and 11:22 - thanks.
I have muscle to spare if it means shedding some fat - I can bench 255 lbs. and I can gain muscle pretty quickly, so honestly it's okay
I am looking for that Matthew McConaheigh - Brad Pitt physique that my wife seems to dig- that seems healthier vs. bulky or skinny guys
As far as tiredness and performance I am not really worried about those for a few months so no worries.

If you are basically eating negative 2000 calories a day...

...are you getting the value of all those nutrients or are they being burned off too as energy ?
