I really must learn to shut my cakehole!

I really must, this is serious. I'm eating too much cake. Can't get enough of it! But what about my biscuit hole? That too! (They're one and the same). I don't know what it is, but cake and biscuits are fantastic. I love them! But you can get too much of a good thing and in my world that's an occupational hazard.

A few years back I embarked upon a diet. I limited myself to just three slices of bread per day (which was a little better than my (easily) one dozen slices. Put it this way, I'd wake up in the morning and have between two and four slices of bread, normally with marmalade (something I've given up completely, along with any 'spreads', so jam, honey, it's all been off the agenda for years now). Also off the agenda, 99.9% of the time are chocolate bars – wrapped chocolate like Twix, Mars bars and so forth. There was a time, about five years ago, when I lapsed for a while and enjoyed a Mars bar once a day, but that was short-lived.

I could have done without the dessert...

I think it's foodstuffs (better make that food groups) with the letter B, so bread, buns, biscuits and now, of course, beer, since I've stopped drinking (coming up for five months on 28 March – actually, that's today!).

But of late I've lapsed on the letter B foods. I simply can't resist a biscuit or two during the day and I really wish this wasn't the case. I've also lapsed on cake. Whenever I visit a National Trust property, which is roughly once a week (forget the culture, I go purely for the cake and the gift shop) I enjoy a slice of cake. And then there's Westerham's Tudor Rose café, where I've been a regular fixture over the past few weeks, and guess what? There's a great selection of cakes. Only last Sunday I enjoyed a chunk (make that a brick) of bread pudding and the week before there was a rather nice Bakewell tart with icing and a large cherry and just a day before that a lemon sponge with lemon curd sandwiched between the two sponges and lemon icing on top – wonderful, yes, but good for me? Well, spiritually, perhaps, but I've noticed my trousers are a little tighter, which means they've got to stop.

I've forgotten to mention my weekly trips to mum's. My mum makes exceedingly good cakes and I make a point of having two slices (make that chunks) with my tea and I have been known to raid the biscuit tin too – it's all got to stop. Perhaps I'll stop everything but my weekly ration of mum's cake. Yeah, that's what I'll do.

Now that the severe weather has lifted (that said, it's raining today and for the foreseeable future no doubt – it's the Easter bank holiday this coming weekend) I'm getting out at lunch times for some long walks and I've even walked to Merstham railway station some evenings. That's the good news. I'm also guaranteeing myself 40 minutes of additional walking everyday simply by taking the train from a railway station 20 minutes' walk away (as opposed to just 10).

Breakfast and dinner are fine, it's just the bit in between that is causing problems. While my lunch, give or take, is fine (normally baked potatoes, heatlhy stuff, or a sandwich from M&S) it's the snacking in between that's an issue. God forbid if anybody has a birthday in the office as the rule is they have to bring in cakes and stuff and most people push the boat out and display an array of goodies, normally from Sainsbury's, including mini millionaire's shortbreads, doughnuts (I'd only eat the custard ones, but they never get them) and other snacks that carry labelling saying 'not good for you'.

Fortunately the summer is coming, and that can mean warm weather. Warm weather suppresses the appetite a little and with sunshine comes exercise, so the future is looking good, but I must resist foods beginning with the letter B and as I said earlier, there's loads of them, although a lot of them good be grouped under the title 'Baked Goods'.

My rule on chocolate has been broken a couple of times this week as I've bought, as part of my lunch from M&S after a walk, is a small bar of chocolate (containing tumeric – so I think it's healthy). The bar boasts just 144 calories (not bad) so, well, no more, let's say that, no more.

Anyway, that's just to let you all know where I am on the dieting front. I'm not doing too bad in the scheme of things, but I think my report card would read 'could do better'.
