i know that if you're on a large calorie deficit your body will think it's being starved and will try to reduce muscle to reduce the amount of maintenance calories for the next day.
i've been thinking about it, so what if you did a lot of exercise with a fairly large calorie deficit but not enough to make your body think it's starving, would your body primarily burn fat?

anything more then 3500 per week / 500 per day calorie defect and apparently your body will start to burn muscle.
just eat 500 calories less then your maintinence and exercise cardio 3-5 days a week with weight training 3-5 days a week and you should consistently loose 1-2 lbs of fat while maintaining your lean muscle mass.
hope that helps..

from personal experience, yes it would burn primarily fat if you exercise enough, b/c when your body empties its glycogen stores, it turns to fat, not muscle, and you basically maintain the same state as one would achieve on ketosis
just take "The Biggest Loser" for example, those contestants train like crazy on severely cut back diet. the only muscle they're losing is a result of weight loss when their legs aren't forced to manuever 300lbs anymoreLast edited by natescope; 06-09-2007 at 06:45 AM.

Well... your body uses muscle for energy if it thinks you're starving (see gluconeogenesis)
That's why going into too much of a calorie deficit is detrimental.
500 calories is really a ball park. I think the real formula was something like 32 calories per pound of body fat you have is the max caloric deficit including exercise.

Everyone is different. Everyone's body responds differently. Some people might lose muscle going on more than a 500 calories a day deficit but some can handle it. I have been doing a defecit of 1000 -1200 calories a day and have been consistently losing 2-3 pounds a week for months now. I keep my protein up and lift weights hard every week hitting each muscle twice a week. Add to that 30 minutes of cardio 5-6 times a week and I have had great results.
Everyone likes to say no more than 500 calories a day but you must remember that this is a guidline, NOT A RULE.

If you're concerned about your calorie deficit forcing your body to burn muscle, perhaps you should look into a ketogenic diet. On keto, your ration of fat-protein-carbs is around 65-35-5. After a few days your body will exhaust it's glycogen stores, and a low carb intake will not be enough to replenish them, forcing your body to use another fuel source. The high quantity of protein will help spare muscle, and the very high quantity of fat leads signals the body to use this as fuel since it's so abundant. A 500 calorie deficit on keto is much more muscle sparing than any other diet I've yet encountered. It sounds counterintuitive, but it works for most people.

I just read an article in Time about how the majority of biggest loser contestants gained back most if not all (and then some) of their weight. They tried to imply the only way to keep it off is to do what the one girl does and exercise 6 days a week for 4 hours+ (which is pure BS).
The bb.com way is generally 1-2 lbs a week (3 lbs if you are 300+), but of course there are always people who like the more extreme stuff.
If the OP is really 5'9" at 147 lbs you definately need to add muscle mass....

OK then, here's a recent interview with Marty from the last season of TBL, talking about how he and Amy (also from the same season) are now motivational speakers, personal trainers, although there's only a very brief mention of their current training.

You need ton consume your resting metabolic rate's base calorie intake for basic functioning & maintaining. Add EE (Energy Expenditure) on top of that and you find yourself in a calorie defecit... enough to lose body weight.
To promote bodyfat loss... depends on the type of exercise and your habitual eating habits. Through training this can become more occuring to burn body fat.Enter.at.your.own.Pleasure
