Cant eat enough???

HI guys

Yesterday was the first day I took MFP seriously in conjunction with Insanity. I aim to end the day with 1800

Yesterday was 'Cardio Recovery' day so I only burned 380 cal ( I assumed 10% would have burnt off without exercise so added 342 to MFP), I use a HRM

I added all food and teas/ coffee consumed and came up short by 362 calories.

I felt like I eat like a pig towards the end, I know now to better spread the meals/ snacks.

yesterday for brekkie I had grilled pork loin, slice of wholemeal toast and a tomato (215 cal)
lunch was pork loin, rocket lettuce, tomato, beetroot, boiled potatoes (333 cal)
dinner was chicken breast, 3 egg ommlette (1 full egg, 2 egg whites) with mushroom, pepper and onion. As my caloreis were still low I bumped that up with 120g of cooked couscous. (total diner - 566 cal)

I snacked on fruit (apple, banana, dried goji berries, tangerine, flaxseed, cabbage, cucumber, blueberries, mango, pineapple, yoghurt and another pork loin, cashew nuts. the majority of the snack list was in the form of a smoothie. total snack calories - 674.

total calories consumed - 1788, total exercise 350.

That was a genuine struggle on a day where Insanity was massively toned down, I typically burn off 800 cal in one work out!!! how can I get closer to my required calories??

Today as an example:

Breakfast - porridge (304 cal)
lunch - tuna salad with potaoes (318 cal)
Dinner - (tbc) lets say 600 cal
snacks - fruit, nuts (438 cal)

That leaves me with 140 calories for the day to hit my goal until I do Insanity by when I will have a deficit of circa 940 calories!!!!

I thought I could bump up with a snack after work (before exercise) of wholemeal bagel with low fat cream cheese and smoked salmon but that's not going to get me anywhere near my target!!!

On top of that MFP has told me I consume too much sugar, I put sugar in my porridge (2 tea spoons), other than that its from fruit which in todays case is apple, banana, dried goji (10g) and tangerine. I also have 30g of cashew nuts.

With so little fruit how am I having to much sugar???? I don't add sugar to anything!!!

thanks in advance for your help
