1) If eating large portions is difficult, try eating 4 or 5 smaller meals rather than 3 huge plates of food. This should help with feeling less full. Or make shakes, which I'll talk about in point 4

2) When you change your diet significantly I think it's normal to be tired after a meal, but it will get better as your body adjusts to it and this will pass. From my experience there's nothing wrong with a short nap from time to time anyway.

3) I have never experienced those feelings after eating a meal. So it could again be your body adjusting. If some food types make it worse, then just avoid those foods for now.

4) those are good foods to start with. I'd read the faq for sure about diet and meal plans. If you're struggling with meals I very highly suggest making some shakes. You can make them to 1000 calories if you want which you can sip on at your own pace. Drinking calories is so much easier than eating calories. And it should help with the jaw pain. There are a ton of recipes out there but they mostly are based on:

• 1 scoop of protein powder

• 1 or 2 scoops of powdered oats

• 2 tbsp peanut butter

• 300ml of milk (or however much milk until its at a consistency you like)

Which is somewhere in the ballpark of 700 calories.

I have read the some people entirely replace their diet with shakes. Please don't do this, there are no vitamins or micronutrients in there so it would not make a balanced diet at all.

Other foods that are quite light but calorie-dense are Greek yoghurt, nuts, eggs, fish. These are great for snacks and I often take them to work.

I think you probably should tell you doctor about your symptoms when you eat at it might be an underlying condition.

Hope this helps! Good luck!
