Ten Ways to Beat the Low Carb Flu.

The low carb flu is real and it's terrible.

While it doesn't kill as many as the Spanish flu of 1918 did or inspire the amount of panic

seen during the 2009 swine flu epidemic, low-carb flu has dissuaded millions of people

from pursuing and sticking to a healthy diet. You can laugh now that

your fat adapted and humming along on stored body fat, but you've forgotten just how terrible the

transition from sugar burning to fat burning can be. Do any of the following symptoms sound familiar?

Cripling headaches. Brain fogs so thick you almost welcome the headaches for cutting through it.

Malaise, fatigue, listlessness, and other synonyms for exhaustion. Lightheadedness and dizziness? Iridability.

A sense of impending doom that you suspect would give way to bliss if only you'd have some ice cream.

At some point, you'll just have to accept the reality of the situation.

You're shifting from a sugar-burning metabolism to a fat-burning metabolism.

You're building the metabolic machinery necessary to burn fat.

You're updating your body's firmware, and it's a big update.

Coincidentally, this is why I recommend plugging into a power source for the duration.

That takes time.

If the results of one study are representative, it takes about five days on a low-carb high-fat

diet to increase AMPK and start building new fat burning mitochondria.

And sure enough, most people report that the low-carb flu lasts from four to seven days,

right on target.

But that doesn't mean we have to like it.
