I really think your nurse was talking out of turn. There is no possible way that she can say "you won't ever get off". Since she doesn't know if your blood pressure problems are hereditary or weight related you'll just have to wait and see when the weight comes off. Even though I haven't lost huge amounts, my blood pressure is more under control now than it was at my highest weight and my doctor always assures me that my numbers will be better the more weight I lose.
Stacey, what kind of "junk food" are you talking about? Do you mean fast food meals? Or do you mean snacky stuff? If it's fast food then my best suggestion is to research some of the places he likes to eat so that you know what choices are saner for you and your eating plan. Even Micky D's has nice grilled chicken options now. Their new Snack Wraps with the grilled chicken option are really good and they have some really nice salads as well. If the trouble is snacky stuff then my suggestion would be to get yourself some snacky stuff that you like and that is good for you. Kashi makes a number of cereals that are really satisfying eaten dry as a snack. Fruit is an obvious choice. Fat free, sugar free pudding and jello are good choices. Even Frito Lay puts out a "light" potato chip that's not bad in moderation. Just beware of portion control. It can be done. Honey and I have a snack every night while we're watching TV. I know others would say that's a bad habit that we should break, but I prefer to not josstle my life around too much and still be successful.
Hang in there.
