Food and Mood -- a followup

So we tried the experiment two days in a row. Replace part of the morning serving of grain with an egg. Won't that stick with her longer? No, she says. She enjoyed having an egg for breakfast, but was famished by midmorning, whether or not she had her egg with a teaspoon of orange marmalade. She offered the rest of her hardboiled eggs to the rest of the family, and is now again happily eating a cereal-and-milk breakfast every morning.

Hi - I followed your link to this post from Bix's blog. One thing to keep in mind when switching from a high-carb to a low-carb diet is that it may take more than two days for the hunger-alleviating effects to kick in. There seems to be some variation in this - I don't know of studies that have been done, but anecdotal evidence hanging around the low-carb blogosphere suggests it could be as much as 3 to 5 days.

The other thing, though, is that the extra shot of protein may not increase satiety if the rest of the diet is still high in carbs. This is what I mean when I say protein increases satiety.

This is not to say, of course, that you should force feed your kid eggs, just that it might take longer to be a truly effective experiment!

Hi, again - I just looked up the original Food and Mood post, and there may be another explanation why the experimental meal didn't help your daughter. When I look at the macronutrients, it looks like you decreased net carbohydrate from 60 g to 56 g - not a great net decrease - and unless there's a mistake in your analysis, there's slightly less protein in the egg meal. And sugars are still at 25 g.

What if you replaced the oatmeal completely with two eggs and offered your daughter a low-sugar fruit like berries or a small clementine? Or even a little meat - ham or turkey ham ...

I wasn't trying a low-carb breakfast. I just wanted to drag out the rate at which the sugar gets into her blood, so she won't "run out of steam" before lunch. I think the egg replacement was just wrong for someone running on carbs. It decreased the energy available to her. I like your high-fiber fruit idea. She used to eat fruit as a midmorning snack, but they don't always do snack-time in 4th grade!

I'm just fiddling around the edges, not considering a Zone or ketogenic diet for my child.
