Increase appetite / up-regulate metabolism - is fructose the key?

Answered on August 19, 2014

Hi hackers,

I'm quite lean, actually a bit too lean in my opinion. Also, I'm currently low-carb (50g-100g per day) due to IBS, this works best for me. The problem is: It seems I don't get enough calories, feeling cold/lethargic all the time. Anyway my stomach is always full, there's no way I could eat more.

Somehow my body seems to be in stand-by mode (I'm getting my thyroid checked soon, just to rule this one out).

But today something interesting happend: I ate some berries which obviously contain fructose and my appetite increased, thought that wasn't much carbs in total (maybe 20g).

The question:

Is fructose the way to signal my brain, that the winter is over, fruits are flourishing in nature and it can up-regulate metabolism?

Or is it actually the insulin spike caused by the fruits that increase appetite?

Any strategies aside from that?

Thanks =)

That was the missing link for me! Thanks! Depleted liver glycogen inhibits Thyroid function and therefore leads to my lethargy. Fructose on the other hand is forced into liver glycogen and solves my problem. Just bought honey and took 2 teaspoons right from the jar - and I feel great! Warm hands, energy, clear mind. I guess I'll stay below 100g carbs per day, but replace some rice with honey. Thanks again!

This just in: only elite athletes store glycogen in their livers.

According to Danny Roddy:

"Keeping the liver "energized" is an important factor in thyroid health. The inability to store glycogen, the storage form of sugar, can decreases the conversion of T4 to T3."

Since fructose can only be metabolized by the liver, maybe you're doing your thyroid a favor by repleting your glycogen stores!

And if you haven't checked out Sugar: The Bitter Truth, 1 hr 01 min may be of interest to you.

When I eat VLC for an extended period I do notice not being very hungry. If you are underweight obviously this isn't what your shooting for. I've always preferred a couple pieces of fruit to the tubers, but I think it is very individual. Definitely play with it a bit to see where your thresh hold is.

Only one way to find out! I'd suggest eating more berries, and seeing how you feel.

Also, check out Melissa McEwen's post on IBS and paleo- http://huntgatherlove.com/content/why-paleo-didnt-fix-my-ibs Interesting stuff about fiber and carb types.

Focus on the thyroid.

The rest may be "CDNEC." correlation does not equal causation. Maybe there were bugs in the berries and you really got protein.

I'm just sayin...
