Third time lucky

I'm getting on it again for the third time, trying to pinpoint where I keep failing.

So I weigh 129lbs (was 56.9 on the 9th, just finished period though and resent weigh in was today so not sure how much of that is related)

Height 5ft.
Age 29
Waist 35 inches

According to my scales I am:

BMI 24.8
Body fat 36.6%
Fat free body weight 36.4%
Body water 43.5%
Skeletal muscle 37%
Muscle mass 34.2kg
Protein 14.3kg
Metabolic age 32

My overall goal is to get rid of this belly fat, I'm told it's all down the deficit which my calories are set at 1200 per day.

Do you think there is anything in particular I should be avoiding? Food wise?

To start with I am trying to cut out sugars, with exception of half a spoon in coffee/tea.

I am eating snacks like biscofi biscuits one a day, sometimes I will snack on a few rice crackers. Banana, apple, oranges and Passion fruit are my main go to fruits.

My food diary is really bad since I have only re-joined again today.

As a snap shot food consists of:

Breakfast (if I have it) toast best of both, two slices, butter and Marmite. If it's the weekend and I have time I sometimes have eggs poached or scrambled on toast.

Lunch: usually a ham sandwich, home made.

Dinners for the last week or so have consisted of:
- cod fish cake with boiled potatoes
- beef casserole (slow cooker)
- Maultaschen (German parcel thing) with scrambled eggs
- chicken and chorizo paella (slow cooker)
- spaghetti Bolognese
- baked haddock, potatoes, asparagus and hollondaise sauce
- hot dogs in brioche rolls (tonight)
- chicken chipolata sausages with potatoes and Yorkshire pudding.

Looking at that I guess it's pretty carby and not enough veg?

Drinks I usually have water, tea, coffee usually sit around 1500ml. Have cut out lemonade and substitute with sparkling water now.

Exercise is pretty much non existent.

Used to work full time in a hospital so was fairly active with work but am now full time studying.

Have a gym membership (yet to use)

Have tried working out at home with dvds ( can never seem to stick to it)
I do have some weights at home and was thinking to start out with ten mins exercise a day in the morning and see how long I can stick to that for.

Any advice on what I could change diet wise and exercise wise?

Is there a particular area I need to worry about?

Sorry massively long post, I just want to change my lifestyle and become healthier because otherwise everything is just going to keep going up and bring problems later in life.

Thank you
