On healthy eating

The problem with sitting on a train for a couple of hours a day and not going dancing or doing trapeze or even walking to and from work each day is that I've been getting a bit podgy. So I'm trying to cut down on calories.
The maths:
Daily calorie intake for a man is about 2550. Now this is just an average. I'm sitting down all day so it's probably closer to 2100. Fat people eat more than thin people without gaining weight, and a pound of fat burns a few calories just by itself. The point being that just be reducing calorie intake, or increasing calorie expenditure, the body will eventually reach an equilibrium position. Fat is a highly efficient energy storage unit (3500 kCals per lb) so this would take time. Mathematically it would take an infinite amount of time because we're looking at a convergence but the real world isn't quite that well regulated.
Ideally then, If I avoid the equivalent of a mars bar a day, or do some light exercise for an hour a day, I'd burn of a pound every 2 weeks.
And this is where things get complicated. And also slightly surprising. There are more calories in the healthy looking crunch cereal I had this morning than the sugary crunchy nut cornflakes I had last night. 100g of rice has 350 calories which is more than that in a mars bar (granted that's a lot of rice and the rice is probably better for you). Adding 30g of cheese to my pasta will increase the calorie count by 100. I have no idea how much the difference is between the healthy option at work is and the normal option.
Long and the short of it is I have no idea how to accurately gauge my intake. So i figure I don't really care. I'll just take some ad hoc exercise and snack on fruit rather than chocolate. I would let you know how it goes but I have no intention of being a fitness fanatic. Still, would be nice to be below 13 stone by September.

Date: 2010-03-24 12:17 pm (UTC)A quiet 25 mins pootle on an exercise bike at the gymn burnt a bit over 100 calories.
Which I later found is about the same number of calories in a Shortbread finger...
No wonder I had issues with tight trouser waistbands when I had a bit of a shortbread nibbling habit at work!
Have you considered some form of self-enforced regular walk or gym equipment use?

Also eat earlier and never last thing at night (i think after about 8pm is supposed to be bad).
Anyway, i don't know how much of this is just myth but i think some of it works, and just changing your routine is much more effective than calorie counting.

Date: 2010-03-24 02:01 pm (UTC)I do have my main meal at lunch.
Any suggestions for a light protein based evening meal? Typically I do spuds, rice or pasta, because that's easy and scales down easily but if I should avoid carbs, that's exactly what I shouldn't be eating.

Oh Chilli! Lean mince red onion red chilli tom puree coriander, bake a butternut squash and scoop out half the insides and stir through the chilli, serve in the remaining squash with some spinach. Not that light though.

I dunno, seems easy enough.

WRT not having time to cook in the evenings, make big batches of soups, stews and curries (veggie once can be low-fat) to freeze and eat over the week. I can share recipes if you like.
Also, Quorn is teh ebil, tofu is better ;)
