Tired, dizzy and hungry would suggest two things to me - firstly that you're not eating enough fat and second, that if you're drinking plenty of water, that your electrolytes are out of balance, so you need to be consuming more sodium, magnesium and potassium.
From your meals, it looks to me like you're not really eating enough:
Day 1
Breakfast - chia porridge made with coconut milk, almond milk & cocoa
This looks OK, although I'm not sure how much fat there will be in this? Without knowing what brand of coconut and almond milk you're drinking, it's hard to know. But you should be making sure that you're eating more fat than protein
Lunch - homemade chicken liver pate with seed crackers (both from keto cookbook), salad with lettuce, tomato, avocado & caesar dressing. Small amount (10g) of 85% chocolate
Again, not sure how much fat you're getting here. I don't know what's in your seed crackers.
Dinner - courgette ribbons with smoked salmon, cream cheese and cream
This doesn't sound like much food - but again, without knowing your portion size it's hard to comment!
Snacks - some slices of ham, a few pine nuts, celery and cream cheese, pepperami
This sounds like quite a lot of snacking; it's also bringing processed food into your diet, along with smoked salmon which is also a processed food.
Drinks - 3 teas with lactofree milk, water. Total liquids about 2 litres
I don't know how much you weigh, but 'about 2 litres' does imply to me that you haven't really drunk 2 litres! Getting enough water is really important. (And hunger is often wrongly interpreted as thirst, so you should always drink more when you feel hungry!)
Day 2
Breakfast - seed crackers
Why only crackers?! No wonder you're getting hungry. This isn't a WOE that's about deprivation.
Lunch - similar to yesterday, but with blue cheese instead of avocado, and 1 slice low carb bread instead of crackers
Sounds to me like you're introducing carbs/carb substitutes instead of protein and/or fat.
Dinner - kale, mushrooms, spinach & prawns in a coconut milk, coconut oil & spice broth (from keto cookbook)
How much fat did you use here?
Overall, I suspect that you're not getting enough fat and protein, and you're probably overdoing the carbs. Forget MFP - it's not really that accurate.
Your meals should be based around fat and then protein - and only then carbs. Forget the carb substitutes.
Make sure you're drinking plenty of water, and also get more sodium - drink a hot drink made from Oxo/Bovril/Marmite. And also eat salmon, avocado, spinach and full fat yoghurt.
And make sure that your portion sizes are decent! This isn't about starving yourself.
