How long does it take to lose body fat?

[creatinegenius]

I do about 30 mins of cardio each day and burn about 500 calories at each session. I usually do my cardio in the morning when I don't have any food in me at all so my body is forced to use fat as its fuel. How long will it take to drop about 15 lbs with this routine? My diet is about 2,000 calories. I am 175 lbs.

[jdmalm123]

Your BMR is about 2000 calories, so you are barely eating enough to maintain health. Still, that would mean you are using up to 500 calories of fat/muscle as energy for the difference. As long as you stay with it, you could lose 1 pound for roughly every 3500 calories you burn, so that's a pound per week. (500 kcal x 7 days).

Now, hear this: If you are not lifting weights and eating adequate protein, you are losing as much of that weight from muscle as fat. That means, when you stop the cardio and dieting, you will have less lean mass and will gain back more fat than you had before.

what level of lifting should be used to maintain the muscle
I'm always curiuos about that

and why is someone that is 175 lbs tryig to drop fat
are you sure you need to at that weight?

[boxtrot]

kane fan u haver 16,000 replies but you're asking basic questions like that? Why??

Almost any level of lifting will do the trick but diet is key.

The person in question who is 175lbs could be fat, thats why.

Hey man,

Question: From the BMR formula it looks like its independant of body fat %. Is that the case?

I mean how can somebody weighing 200lbs with 40% fat get the same BMR with somebody weighting 200lbs with 8%? Wouldnt the guy with more muscle have a higher BMR?

Thanks

I think thibdeau says 2 levels.

BMR/RMR is a baseline for maintaining health assuming zero activity. It's the other calories over BMR where most people over-eat or under-exercise.

fat at 175 is unlikely unless you are rather short or have never had any real physical activity
as for asking, um when smart people want to know something they try to find out, a good way to do that is to ask a question in an area the topic is being discussed you see. as to why I didn't know it before which is obviously your little shot you are taking at me, well I never bothered trying to lose weight before

Best advice you could've given him. Keep the muscle you have> lift weights. If you're too tired from the lower calorie intake then lower the weight, but try to keep lifting heavy. Lifting heavy weights will keep up the need to maintain muscle.

There is alot more to it than just lifting, you need to "control" your bodys hormones.

http://www.abcbodybuilding.com/magaz...urningdiet.htm

have a read there

It explains the roles of insulin Glucagon and cortisol; tells you what you need to do to control their release; its all about diet.

It also has a diet that maintains your metabolism and minimizes the burning up of muscle while on a calorie defecate.

YOU NEED TO READ ALL OF IT.

After you have your diet right you just need to lift as normal.

[Kane Fan]

thanks I'll read over that
I have been dropping some weight lately and I'm hoping it's all fat
or at least like 70% fat
but I'd rather it was like 95 or 100% fat I am ditching
I don't seem to be any weaker but I'll find out next time I lift

Great article mate. Gotta love these forums. learn something new everyday.

BMR/RMR depends on lean body mass not total, thats how muscle versus fat is taken into account. - I'm at a good ~ 2600 cals.

2600 cals should make up around 70% of my daily energy expenditure => my total daily expenditure is 3700 cals

Isn't this too much?

Have a read; it's short and concise and to the point.

I want to high light 2 things though:
HIIT and eating before running in the morning. Further explained in the thread.

My BMR (2000) plus ADLs (500)= approx 2500 kcal/day
My BMR (2000) plus ADLs (500) plus workout (1000) = 3500 Kcal per day

Bigger guys who lift weights can easily need 3000-4000 kcal per day or more.

How do u know how tall this person is? How do u know how much physical activity this person has done? You dont, therefore your point is invalid.

Good for u.

his BMR is clearly higher than that, unless he sits in bed all day and doesn't move a single muscle

I see why you are so deep in the Red
your not very bright
my statement makes clear that I do not know how tall he is but you seem to indicate that I think I do?
same with the physical activity....
if you get any smarter maybe you'll get some Green next to your avatar..

[jdmalm123]

VERY GOOD!

BMR is based on calories needed to maintain basic life functions when you are completely at rest...i.e. sitting in bed all day and not moving a muscle.

That's why you have to add calories for exercise and ADLs (activities of daily living).

You have to strike a balance between CV intensity and duration, the amount of weight lost per week, how much you eat and the resultant quality of your weights workouts (strength levels, volume etc).

For proper cutting, weights comes first really. You need to try and maintain strength on a cut to preserve that muscle. Tweek your diet and CV to fit round the workouts and still get a calorie deficit.

But you will get weaker and lose some muscle on a cut. It's inevitable. Don't worry as long as it isn't drastic. BTW, you may not need to do cardio every single day. Maybe 5 times per week max would be fine. Tweak the diet and hammer the weights more.

[powhippie]

ok cause i was thinking i need to do more cardio...im only running like 10 min a day...i hit the weights for like 2 hours 5 days a week. like my bench has increased from 185x5 to 205x5 in about a month but everything else hasnt stayed the same but im losing mass. And no matter how much i eat when im running im hungry in like 30 min again..should i be eating more filling foods or what? i eat lots of fish, chicken, and greens
