There's a lot there. Let's go through this in stages.
i was 24 stone at the age of 18, and i understand that has more than likely caused me to become diabetic my eating habits were terrible.
NO.
Type 1 diabetes is NOT caused by what you eat, or how you eat, or how much you eat. Type 1 is an autoimmune condition. Sadly (or gladly?), there was absolutely NOTHING you could have done to prevent it. You could have been the world's greatest marathon runner and it would still have happened. Do not blame yourself. Your diet did not cause you to get diabetes. The only thing your diet can do is influence how your diabetes will affect you in the long term.
I then stupidly decided to stop taking my medication, as i know this would aid me in losing weight. I have done this cycle time and time again and really i feel enough is enough. I need to be healthy and control my diabetes as i do not want to die from the condition, it is a very stupid things to do.
You are by no means the first person to do this. There's actually a name for it, 'diabulemia'. The fact that you have decided enough is enough and you aren't going to to do it anymore is a major step forward.
I am going to get my diabetes under control, and really i just wanted some advice about diet and what diet methods are safe for a type one diabetic
Good for you. And this question is less simple than it sounds.
I'm going to suggest something which won't be to everyone's tastes here. The following is NOT medical advice. It's ideas that should inspire you to do your own research and consult with qualified professionals.
You say you want to avoid the yo-yo cycle. Therefore you need to get to grips with some basic points about fat storage.
Body fat is not caused by eating too much fat. Or even eating too much. Body fat is excess blood sugar, converted by insulin to an alternative form for storage.
Whenever there is more sugar in your blood than your body needs, provided there is insulin, this excess sugar is converted to body fat. Insulin also inhibits the metabolism of fat.
That's why when you don't take your medication, you lose weight quickly. Your excess blood sugar just stays there, and instead of being converted to fat, rips your body to shreds like sandpaper. And because your body can't metabolise this glucose, it metabolises the fat.
So in the first case, it looks like you're in a catch-22. If you take insulin, you put on weight but control your diabetes. If you don't take insulin, you lose weight but you get the diabetes complications.
Except, it's not a catch-22 at all.
There are three major food groups in your diet: protein, carbohydrates and fat. Only carbohydrates affect your blood sugar level significantly, which means you need to take more insulin for them.
In other words, if we know that taking less insulin promotes weight loss, then logically if there was a way of taking less insulin WITHOUT affecting your blood sugar, that would give you the best of both worlds - weight loss and diabetes control.
See where this is going?
The dark and dirty truth is a salad baguette will probably in the long run make you fatter than eating steak and eggs. Therefore you may want to investigate what impact reducing your carb intake has on your weight and your control.
Importantly though, you need to be on a basal-bolus regime for this to work. You say you have two types of injections but it's not clear whether you mean you are taking a basal and then bolusing when you eat, or if you are on mix insulins twice a day. You CANNOT reduce your carb intake in mix insulins. So if this is the case for you, a very good first step would be to shift to a more intensive but more flexible insulin regime. Giz a shout if you want some more pointers, this is just the initial overview.
