If you really want to lose weight you'll have to do something about your diet! Whatever diet you end up following, what you're eating isn't right. It's high carb, high calorie and high fat.
From a carb perspective:
Digestive biscuit
In one McVities digestive biscuit there are 9.3g carbs. If you consider that in the induction phase of the Atkins diet you're only allowed 20g carbs per day, you can see that this is adding a lot of carbs to your day!
Porridge with milk (skimmed) honey (small bit) and large pear
Obviously I don't know what brand or type of porridge you're eating, but to give you an idea, a ready made pot of Quaker Oat So Simple (to which you just add water) contains 31.2g carbs. And that's before you add honey - Sainsbury's Runny Honey is 12.2g carbs per serving - and the pear, which will add 35g carbs.
So that's around 80g carbs before you even get to your lunch!
Lunch was fry up - 2 rashers bacon, 2 sausages, mushrooms, baked bean, halloumi cheese and 2 slices white toast
The bacon is fine, from a carb point of view, but the sausages could be very carby, depending on the brand/type you chose. Mushrooms are brilliant for low carbing, as is the halloumi, but the baked beans and white bread aren't. 1/4 can of beans is around 13g carbs and 2 slices of white Kingsmill, medium slice, will add another 37g carbs.
1 x G&T plus about 10 Mistrels at cinema
The Minstrels will be around 18g, and if you had a full sugar tonic with your gin, a 150ml serving would add another 7.7g
Turkish chicken pilau (add aubergine, raisins, parsley and 0% fat Greek yogurt as garnish) plus rice and chicken and tomatoes.
This is harder to work out, but to give you an idea - aubergines are great for low carbing, at only 2.2g carbs per 100. However, raisins are 69.3g carbs per 100g and rice is 46g carbs per serving.
About 4 cups tea skimmed milk, 1 camomile tea in evening. 5 large glasses water.
Depends on how much milk you have in your tea, but let's say it's half a serving, which is 200ml, this will have added around another 5g carbs.
So well over 200g carbs, based on these estimates. A rough rule of thumb from Dr John Briffa, who wrote "Escape the Diet Trap" is that we should aim to have around 100g carbs per day, to not gain weight.
