Portion size

How much food do I eat at the two meals?
I am currently “loading up” at each meal.
My thought being “get it while you can! This is the only opportunity for food over the next X hours!”
Whilst this thought is accurate – I’m NOT getting more food until the next meal – I’m wondering if the sentiment is too dramatic/ negative. I’m trying to re-frame thought to “I get to fuel my body now so I have energy for x hours”. It’s all good food and what is on my plan. It’s just the quantity I’m questioning. If I am eating to over-full so I don’t get hungry in between… isnt that a bad thing? Stomach shrinks during famine then expands during feast?? 🧐
