Thanks all, good advice here as expected. I guess I was a bit misled after reading the carbohydrate curve and seeing that 50-100g was the way to go for weight loss, so I figured a 50g meal and whatever fruits and "passive" carbs would keep us in that range, but it seems the insulin and whatever else is in play here is working against us faster than the lowering of carbs is working for us.
I'm getting out an Excel spreadsheet and planning out all our meals for the next week to remove the temptation, because we have really bad habits when it comes to pulling something out of the cupboard and microwaving it, or just cooking up some spaghetti. I'm going to pick out a bunch of recipes from the site and try some different things. The bad thing is that there's no Trader Joe's around here (eastern Nebraska), so almond meal and such are really expensive. But even in the wonderful world of meat/veggies/fruits there's enough variety to make things work.
To answer the other questions she's in the high 170's last I checked, 177 or so, she's 5'3. Not horrific, but we both know the health benefits of being closer to a better weight for her height. I've stopped talking about it in terms of weight though because that's a motivation killer, instead I'm just saying we're going to eat healthy, here are the benefits, etc etc.
Mia made some good points on that as did the rest of you. Primalchild makes a lot of sense with the viewing sugar/carbs as a drug.. I'm more or less there, but it's really hard to defeat 20+ years of brainwashing and bad habits. It's worth it though, and I'm committed to Grok out. Starting today, no more grains on our plates and bowls! I can't tell you how motivating it is to have such a huge community behind this, it's the whole reason it's successful. Let's keep being loud and proving the science to anyone who will listen, because people deserve better than ignorance-induced obesity.
