I wouldn’t describe what you need as training so much as changes. People don’t dump when they want to, they dump when they need to. Some people like your hubby are just lucky that they don’t have as much of a problem, but when you do have a problem, you need to fix some things.
So you may have a little problem getting your body to “need” to go. I’m guessing that your diet may be lacking in fiber and you might not be drinking enough fluids or exercising enough. You need to have the right combination to get things moving.
If you don’t already do this, start adding fruits and vegetables to every meal that you eat (have strawberries or oranges or dried cranberries with breakfast, have carrot sticks, apple slices or grapes with lunch, have multitudes of vegetable main dishes and side dishes for dinner) and start eating less meat, cheese, processed foods and other fattening/unhealthy foods. I’ve often heard the term “Don’t eat white foods.” That’s because things like white bread, white rice, potatoes, cheese and other full fat dairy foods will stop you up plenty, because there’s little or no fiber.
When buying bread, make sure the very first ingredient on the package is some type of whole grain (not somewhere half way down the list) such as whole wheat, whole rye, whole oat etc. And when you start adding your veggies, try to eat a colorful spectrum of veggies (broccoli, squash, sweet potatoes, peppers, radishes, lettuces (except iceberg) beets, orange or purple colored cauliflower, cabbage, carrots, mushrooms, turnips etc.) You can eat these things raw or throw them into soups, stews, enchiladas, salads, lasagne, or even roast them. Try different methods of prep so you don’t get bored.
For dessert, don’t eat ice cream, cookies or cake. Instead eat bowls of fresh berries with a tiny bit of sugar, or have some whole grain cereal with nuts and dried cranberries, take a plate of orange slices or apple slices with peanut butter in front of the TV. You can also eat popcorn, as long as it’s not drenched in salt and butter (popcorn is a whole grain).
You might also want to consider a fiber supplement. I take 2 that are more accurately described as food, rather than a pill or a supplement. But Metamucil makes a non-flavored powder fiber supplement that you can add to any drink or your morning cereal with milk. It’s less gritty than what I take, but I don’t mind that. Metamucil also makes a very delicious cinnamon fiber wafer that tastes very good, much like giner snaps. I take 1 tablespoon of Bob’s Red Mill ground flax meal and 1 tablespoon of Trader Joe’s psyllium husk in a big old glass of water or juice each day (usually before dinner) so that by morning I’m running smoothly. Make sure you drink plenty of fluid throughout the day and get 30 minutes or so of vigorous walking or other aerobic exercise every day. That should help.
