Breakfast cereal is full of salt and sugar.
Eat some porridge or oat bran made into a porridge and sprinkle on some sweetener if you feel you want to.
Try to cut out as many carbs as you can manage - bread is akin to cake when dieting. Your carb cravings will go once you stop them. Instead of carbs eat some oatcakes - find them in the cracker section and try some different types of nut and seeds. Don't eat a lot of nuts, just about 5 at a time. Pumpkin seeds are also good, as are pine nuts. Nuts contain protein as well as beneficial fats. They are high in calories, so don't go overboard.
Don't make the mistake of thinking that all low fat stuff is good....it's not, most of it is full of sugar - like low fat yoghurts. Eat fat free natural yoghurt instead - add a few blueberries and some pumpkin seeds to it.
Eggs are a good source of protein and you can buy low fat cheddar cheese. Don't eat high fat stuff if you can help it.
Always use skimmed milk as even semi skimmed has quite a few calories in. Don't drink any fruit juices/squashes. Stick to: water, tea, coffee, herbal/fruit teas.
I've lost 10lbs on my diet:
Breakfast: Oatbran made into porridge.
Lunch: Either a tin of mackerel/sardines and lots of salad leaves OR a boiled egg, small piece of low fat cheddar, slice of lean meat and lots of leaves. Don't put any dressing on your leaves. You can buy salad seasoning powder in the herbs/spices section in the supermarket. Just experiment with different flavours.
Dinner: Whatever the family is having - something low fat and homemade, but I cut the carbs out and don't have any potatoes or pasta etc. I have three oatcakes instead. I don't eat a large portion either.
Supper: Small bowl of fat free natural yoghurt with a few blueberries, pine nuts, pumpkin seeds, 2 walnuts and 2 almonds.
I drink plenty of water, nettle tea and ordinary tea throughout the day. If I want a treat I have 150mls of heated skimmed milk and some nescafe powder - that's my way of drinking coffee.
If you feel totally deprived and want a treat then buy a low carb bar or some diabetic chocolate from Boots.
Don't eat too much fruit - it's full of sugars - esp. bananas. You can always just have a few berries if you want a fruit hit, but don't eat too much.
If you have a hypo attack if you're due on or something, then have a banana, some milk and 3 oatcakes. That'll give you enough carbs to recover. You do have to eat some carbs or you'll end up feeling faint. Also, try to get some exercise in each day - even just a quick walk will boost your metabolism.
Think low fat/low carb.
My tip is to totally rethink your eating patterns. Learn to ignore all the junk in the supermarket. It's difficult at first, but it does get easier. If you fall off the wagon, just get back on it next day. Think of it as a lifestyle change and healthy eating rather than being on a diet as such.
Hope this might help you.
