The "running on an empty stomach" theory is just something that the magazines made up and people started to belive it and repeat it. Exertion while hungry will not suddenly alter the laws of biophysics and make the body use fat for fuel. You would have to be in ketosis, and when that happens the body also burns up an inordinate amount of muscle.

Nelson Montana said:I'd say that walking 2 miles burns about as many calories are jogging 2 miles -- which isn't many calories at all and wouldn't make much of a difference is fat loss.
The "Target Heart Rate" theory is a myth based on skewed studies. There is no magic heart rate that suddenly burns fat.

The next source of fuel would be....? Muscle.
Just because you have an "empty stomach" doesn't mean you're gylcogen depleted.
For everyone who says they had success with this method, I can find someone who had equal success without it -- which is another way of saying there were other factors involved and not those percieved.
Swimming is only a good way to burn calories if you aren't a good swimmer. Skilled, leisurly swimming will barely burn the calories of a bowl of oatmeal in 30 minutes.
Eight physically fit women (aged 21-27 years) participated in four separate exercise trials.

Energy metabolism during exercise at different time intervals following a meal.
Willcutts KF, Wilcox AR, Grunewald KK.
Department of Physical Education, Dance and Leisure Studies, Kansas State University, Manhattan 66506.
The objective of this study was to compare caloric expenditure and substrate utilization during exercise begun at different time intervals following a standard test meal or in the fasted state. Eight physically fit women (aged 21-27 years) participated in four separate exercise trials. In three trials, the subjects consumed a 940-kcal meal following an overnight fast and began exercising either 30, 60, or 90 min after the meal. In the other trial, the subjects did not consume any breakfast prior to exercising. Energy expenditure and substrate utilization were determined by indirect calorimetry during the last 23 min of a 30-min run on a treadmill at an average work load of 62% VO2max. There were no significant differences among trials when comparing the total caloric expenditures (range: 215-219 kcal). However, the subjects oxidized significantly more fat (94.3 kcal) when they exercised on an empty stomach than when they exercised 60 or 90 min after the meal (71.6 and 68.8 kcal, respectively) (P less than 0.05). It was concluded that consumption of a meal prior to exercise does not increase the energy cost of the activity for physically fit women, but it does disrupt the pattern of substrate utilization, reducing the contribution of fat as an energy source.
rj420 said:while we are on the topic of cardio I might as well throw this in. Many BB's today are not doing cardio cause of the catabolic effects, and would rather achieve leaness through better diet and drugs. My ? is this: Isn't it important to raise V02 max, thus supplying the body with more O2 rich blood, less C02, lowering of Hydrogen Ions and lactic acid? Wouldn't better aerobic conditiong equate to better performance in anaerobic actions, leading to an increased anabolic environment? I know trying to do both simultaneously would render in anabolic failures, but shouldn't a cycle of both types of conditioning occur for the best possible output? Just wondering what you guys think.
how do you suggest for one to deal with shin splints? i started jogging a while back 2 miles 3 times a week tog et in shape but stopped for 3 months b/c shin splints never went away and got worst. If i start running is that too hard for a beginner or atleast one that been layback for a while? will it improve endurance and stamina faster than jogging? I want and need distance like up to 5-6 miles so I don't think sprint will work for me.
Nelson Montana said:jboldman: This is the problem:
You assume that because a "study" was done it is "hard evidence," as you say. But I just disproved the study! It was not well controlled! It wasn't even conducted properly! Yet, that logic eludes you. You say I am not offering "hard evidence."Logic is evidence, bro. A misconducted study is bullshit. But some people love the numbers and the titles, ya know?
And another thing. Just because a study doesn't exist doesn't mean something isn't so. A_LOT OF PEOPLE NEED TO GET THAT THROUGH THEIR HEADS!!! There isn't a single study to show that poking a five inch fork into my eye is any worse than poking a four inch fork into my eye. But LOGIC tells me it's gonna hurt.
BTW, there are plenty of studies that show aerobic activity lowers testosterone, so let it go man. You're wrong. BUT...you can do and believe whatever you want.

Would Nolva help with this fat reduction at 10 mg ed?

It is realatively easy to talk the body into burning fat preverentially over carbohydrates, simply exercise on an empty stomach and keep the exercise intensity down.

Seth said:This is just my thinking – I don’t know crap but this seems logical to me:
Weight loss is taking in less calories then you consume.
Running, walking and swimming all burn more calories then not doing those things.
You can either do them or eat less food.
I don’t believe that if you burn 400 cals running you will lose more muscle then if you just ate 400 cals less that day. This may not apply to you if you are trying to get from 7% bf to 6% body fat.
Either way you have to be under your maintenance level to lose weight.
If your body started to break down some muscle to fuel your workout, then the extra 400 cals that you consume would go towards rebuilding your muscles – remember, you are still under your maintenance amount of cals, so it is not going to be converted to fat.
Nelson Montana said:John G: You're not serious, are you? You're suggesting that if HR gets too high you stop burning fat? Don't mean to flame son, but you're clueless on this one.
DaMann. Of course skill is a factor. Do you think a skilled runner burns as much energy running a mile as someone who is out of shape? If so, you're way off track.
DKH. The good swimmers dont have good bodies because they're good swimmers. They're good swimmers beause they have good bodies! The fat swimmers don't do as well.
Seth: True, everything burns calories. That's the point I'm trying to get across. There is nothing magical about aerobics.
You can only do a certin amount of activity before you overtrain. A bodybuilder should do the maximum amount of bodybuilding. Why waste energy with something that doesn't build muscle and burns less calories than lifting weights? AND PLEASE NOBODY WRITE TO SAY IT'S TO RAISE HEART RATE! Weightlifting raises heart rate just fine.
