Cardio Necessary for Effective Fat Loss?

There is a common belief in the mainstream, that for maximum (or even effective fat loss) you need to do some form of regular cardio to lose fat. This is simply wrong of course because many people have just dieted to lose fat, without any form of excercise. Of course this is a bodybuilding site, therefore dieting only is not ideal, since it doesn’t preserve muscle that well.

The next decision when going on a cutting phase, is whether or not cardio is even necessary? Weight training is actually more effective than low intensity cardio. Then there is HIIT cardio, which is much tougher to do, but isextremely moreeffective for bothfat loss and muscle preservation. You would still have to do weight training for either form of cardio, to help preserve lean muscle preservation and strength.

So who should do cardio and when?

Most bodybuilders would agree that cardio is a pain. It is a nuisance and most would just rather stick to weight training only for their excercise. It is perfectly O.K no matter if you’re a newbie, or a veteran to start your cutting phase without any cardio. When you first start dieting, the act of restricting calories will be enough to start causing fat loss, even without cardio.

Eventually everyone will hit a fat loss plateau, which is when cardio will be a necessity. You can only restrict your calories so much, before you cause your metabolism to crawl to a halt. The cardio will allow a phenomenon called energy flux. Basically what that means is, you will lose fat more effectively if you eat more, but also burn more calories simulatenously. In other words, it is better for fat loss if you eat more calories and burn more, than to eat less calories and burn less simulatenously.

If you don’t want to do cardio while cutting, your fat loss will be slower. But bodybuilders often don’t want to hassle with the time and effort cardio takes and wouldn’t mind, even if the cutting phase took a little longer. You shouldn’t increase weight training to overcompensate for lack of cardio, that would cause more harm than good. You would wind up overtaxing the body putting you into overtraining state.

The Stubborn Fat Protocol is a cardio routine developed by Lyle McDonald, a respected author of multiple excercise and diet books. The routine is innovative, but it is based on scientific research.

You will break up your cardio into 2 separate sessions. The first session will be high intensity interval training, or HIIT, cardio for 10 minutes. The purpose of this first session is to manipulate the adrenaline / noradrenaline levels to mobilize the fat out of your fat cells. You then take a 5 minute rest after the first session.

Next you do 45 minutes of low intensity cardio. Afterwards you wait one hour before having a protein only meal. Then 2 or 3 hours later you can go back to normal diet, with carbs and fat included in the meals.

The reason why Lyle McDonald says it has to be done this way is because the HIIT portion gets the fat out of the cells, but there is a reduced burning effect at the muscle. It is then that you do the low intensity to finally be able to burn the mobilized fat in the muscle. Mcdonald recommends this workout 3 times a week.

Who should do the stubborn fat protocol?

The routine will be highly catabolic (muscle wasting). Ideally it should be for those who are at a plateau and low bodyfat percent trying to get that last bit of fat off. Overweight people should just stick to traditional routines as they are easier to stick to, require less time, and work well anyways. Only when you start to plateau, will a more aggressive cardio plan make sense.
