I'm not an expert on nutrition, and I've seen some comments made regarding insulin spikes and cutting calories (losing fat).

Can someone elaborate on the correlation?

Spikes before/after training, or just in general throughout the day? To put it simply, you will not be burning body fat when insulin levels are high. It's too general to talk about "spikes" however. How many grams of carbs are we talking? When? How often?

There actually is no correlation in terms of results. The effects on insulin on a cut pertain to hunger and energy. Managing insulin levels will not make you cut faster or more effectively it will just make it easier. For people that don't count calories or follow a structured diet then it could make a huge difference as they are eating randomly and if they aren't as hungry they will eat less.

Insulin and it's effects are largely mis-understood. Sure it may make you deposit fat but then your blood sugar is low and then guess what, your body goes about mobilizing and using the fat it just stored.

I disagree, i'm basing this on the effectiveness of protein sparing modified fasts.

The short story of it all is that insulin is a 'storage hormone' and elevated levels of insulin blunt fat mobilization.

Sure, your scale weight will continue to decrease if you are in a calorie deficit. But since insulin will blunt fat mobilization, you'll lose less fat and more lean mass. Hence the point of a PSMF.

You can't just stop there though. It's far too much of an oversimplification.

Sure it blunts fat mobilization. Then it drops blood sugar. What do you think your body does after that?

Note:

I'm not recommending anyone "not" try to manage insulin levels. I think it's a great thing even just for mood regulation. I do however think it's important to understand how our bodies work and there are many "magical" attributes attached to insulin that are just not true.

I love a good diet argument with Holto.
