PWO Insulin Spike Unhealthy?

We are told to avoid spiking insulin all day, but then that it is fine post workout. We know this is because at this time, spiking insulin would cause the nutrients to be shuttled directly to our muscles and not at all to fat cells.

What effect, however, does this insulin spike have on our pancreas and endocrine system? What distinguishes the PWO insulin spike (given by something like Surge) from the unhealthy insulin spike at any other time, from an endocrinal perspective?

Just a shot in the dark, but would torn muscle in need of repair be part of the reason?

Also were spiking it one time and then getting a balanced meal as opposed to the rest of the world whom spike it and then crash and search for yet another spike etc etc,. the never ending circle

Carbs does not cause spikes in insulin, as previously believed. Read some of the new studies done in the subject. Carbs are not bad for you.

That’s actually a very good question. You might go to David Barr’s new thread in the Authors Locker Room and ask it. He’s very focused on this kind of thing.

I think you’ll find most research on PWO insulin spiking to shuttle nutrients is from a fasted state for endurance athletes. If you follow a diet that promotes consuming most carbs around a workout…pre wo & pwo, then it’s not nessessary to spike insulin at all. And the less you spike insulin the better.

I think some people need to realize that elevating insulin doesn’t necessarily mean spiking it.

It’s also important to point out that insulin sensitivity is significantly increased following training.

10:00 PM eat a huge bowl of pasta and drink a can of soda (not diet). 10:45 go to bed. Insulin (spike) glycogen from food shuttled to fat storage due to inactivity.

Compare this to slamming a Surge after an ass busting heavy metal workout where any insulin rise will be utilized in transporting amino acids and glycogen to muscle cells stimulating heightened recovery and growth.

Like PHil said the danger with insulin spikes comes from continually spiking throughout the day combined with inactivity. The life of most couch potatoes.
