I definitely had the large portion thing going on. For protein and for everything. It took a few weeks to get it through my head and find smaller meals that were satisfying.

And, I tracked not just what I ate, but how it made me feel later, both physically and emotionally.
To the point where I would do head-to-toe checks between meals.
How was my mood; did I feel good or antsy, or hungry; weak or energized.
That was how I made the connections between meals and how my body responded to meals.

I know it sounds kind of, ahem, too attentive, but I was out of whack and disconnected. Not much worse than taking 3 antiobiotics a day if you have strep, is how I think of it now.

FYI, semi-low carb.... can be regular low carb. The people who are on 20 g per day are VLC - very low carb.

Low-carb ketogenic diet (LCKD): less than 50g carbs and 10% calories daily
Low-carb diet (LCD): 50-130g carbs daily and between 10-26% of calories
Moderate-carb diet (MCD): 130-225g carbs daily and between 26-45% of calories

That's from the suggested definitions of the Nutrition and Metabolism Society. Not that it makes any difference, just in case your brain is saying you're not really low carb if you have more than 20 g per day; not quite accurate.
