I’m coming to this quite late in the day but I’ve got some tips for people trying to lose weight (well, I say tips, I’ve written something more like an essay).
I’ve gone from being 70kg to (currently) 61.5 in a year and a half, although most of this weight loss occured over the course of about six months. The real way to be successful is not just to monitor what you eat, but (as others have said) reduce the total amount too. But the other vital thing you need to do is to eat according to the time of day - no, this isn’t like eating according to your blood group or anything ridiculous, it’s an easy and scientific way of managing your vitamin intake. You need different food compotents at different times as I outline below. Coupled to that you should also try and eat according to your need - plan what activity you’re doing over the course of a day and then think whether you can afford to have that dessert/can of fizzy drink/bag of crips/chocolate/whatever. It’s not that you should never ever have them, but that you should only be eating treats when you’ve got some kind of activity ahead that will a) mean you merit then and b) burn off the fat/calories they confer.
Breakfast should always be carb heavy, so lots of wholewheat/grains/fruit - eat as much as you feel you need and it should be as soon as you wake up - if you don’t eat much in the evening then you should be hungry! A good snack at mid morning (say around 10.30) is something like Dr Bircher museli which is utterly yummy and really good for you (it’s basically yoghurt and muesli mixed with fruit).
Lunch should be a full balanced meal - I totally disagree that salad is a filling lunch. Have a proper meat and two veg meal, if you’ve got a canteen (as I do) then this is easier, otherwise you may have to bring your own food it. Please for God’s sake don’t eat a load of lettuce and cold veg and then wonder why you’re feeling unsatisfied afterward. The balance at lunch should be between carbs and protein with a bit of fat, so something like lamb chop with potato and brocoli would be good (for example).
Evening meal - eat as early as you practically can and don’t eat after 8pm (this assumes a bedtime of around 11/12 - you shouldn’t be eating less than four hours before you go to sleep). Your evening meal should consist of protein as much as possible - some chicken without sauce, cold meal and a glass of milk is a great evening meal (if slightly uninteresting). Fish is a brilliant evening meal. You should try and eat as little as possible but have something to ensure your system is still going (otherwise you risk diabetes later in life). I often go to bed on a glass of warm milk or a serving of scrambled eggs - filling, protein-rich and quite light ensuring I wake up ready for breakfast the next day.
The logic underpinning all this is that you need carbs during the day to fuel activity (including the ongoing requirements of just living), and this need drops off as the day goes on. At night time when you’re asleep is when you do most of your muscle growth and tissue repair - this requires protein. Carbs eaten in the evening aren’t properly used and are far more likely to be converted into fat for use later - not what you want.
I’ve been following this diet and have given it to several others who have also had great results with it. My dad (53) has lost over a stone in four months with virtually no exercise just by reducing his intake and planning it as I’ve described. If you throw in exercise to this mix then the weight will plummet as all your excess fat is burnt off really quickly. Forget the gym as a way of losing weight - find an activity that gets your heartrate up that is fun.
Ever been to dance classes? Most modern dance types are like an aerobics workout with stretching and core strength thrown in. Not only will the weight fall off but it’ll get sucked into a tigher space as you tone up too, and you’ll have loads of fun doing it. Ever played squash/racquetball? You burn about 700-1000 cals an hour playing and it’s huge fun too (I’m off for a game in 15 minutes!). If you have a squash club near you join in and see the results - it’s another good sport for toning as well. Successful exercise is about finding something you would choose to do so that it’s never a chore, that way you don’t risk not bothering to go one time and suddenly falling out of your routine.
Phew, quite a lot but hope it’s useful. Let me know if you want to more about anything I’ve described, and good luck with the play!
