Is your mother supposed to be controlling her diabetes with diet only, insulin shots, pills, or what? How long has she been a diabetic? How severe is it-as in, has she ever been hospitalized for high/low blood sugar comas, etc. etc. etc.
Sorry so many questions, but I am borderline/gestational diabetic, it runs in my family heavily, and my mother is a nurse and deals with this all of the time. It will really help to shape my response to you, as to what to do.
I would like to comment, though, that it is absolutely IMPERATIVE that she start following proper care for her diabetes. I know that her doctor tells her things, but some people just don't listen to their doctors. Maybe if you print this out, and let her read my response???
I am simply stating this from a relative who lost someone that they loved from diabetes...and the only reason that my aunt passed (in her early 40's) was because she didn't follow her diet and exercise properly. It was the ONLY reason for her passing.
People don't take their diabetes seriously, and in fact, it is very serious. Most bodies are capeable of processing the carbs and sugars that we eat, and keep our blood sugar in line...it has to work extra hard if we eat too much sweets or crap, but it still is able to handle the load. In a diabetic, it simply can't. When you test your blood sugar and follow your diet, the idea is to keep things in line yourself, since your body can't. When your sugar is too high or too low, it causes stress on your body. It isn't "okay" to have it high one day, and low the next. This causes stress on your entire system, and over time, causes a lot of damage to your heart, circulation-not controlling diabetes leads to heart failure, amputation of limbs, etc.
My aunt played with fire...eating what she wanted, and then overcompensating later. In her last couple years, she was in various comas, had a port in her chest, and ended up passing from heart failure. Her system just couldn't handle the highs and lows in her blood sugar for so long.
It is VERY important that she see a nutritionist recommended by her doctor. At her weight, and knowing that she will fail on a 1500 calorie plan, I would honestly talk to the doctor and nutritionist about having her put on the 1800 calorie diabetic diet. There is an 1800 plan, and it is much better than what she is currently doing (or not doing) if she cannot follow 1500.
Calories count, but with diabetics, WHAT you eat at each meal, and how much of it, also count. This is because a diabetic can only handle so many sugars and carbs at each meal-too little will cause them to have an insulin reaction if they are on insulin...and too much will cause high blood sugar. They also must have a serving of protein at each meal. You have to stay in a certain calorie count to lose weight, but at the same time, you have to eat certain amounts of protein and carbs.
I would fully, fully recommend that you support her by going to the doctor and nutritionist with her, and encourage that she follow the low calorie diabetic diet. Purge the house of M&Ms if you have to...and instead, figure out treats that she CAN have on her plan-so she doesn't feel deprived. (One of my favorites is an apple baked with Splenda and cinnamon on top, in place of apple pie.) Once you have the diabetic diet in hand, you can find diabetic recipes in books or online, that list the exchanges per serving.
I recommend that she move as well, and do whatever she can. Moving is the most important thing that she can do, to help with not only her weight, but to aid in helping the circulatory problems that diabetics often encounter.
I really encourage you to help your mother and support her during this time-and I think losing weight WITH you will help, especially if you have offered to get her rewards, etc. for milestones. I think it is also important though, to stress to her that you love her, and want her around, so that you can enjoy her.
