Here are the two strategies that were difficult but worked for my husband and myself.
Our focus on our meals was difficult. To simplify it all. I just packed the refrigerator with ready to eat, ready to heat meals, at all times, it is stuffed full, that is my job. Once it is full we move on to the next strategy.
In the first strategy, we have bean dishes, stir fries, starches like rice/beans/cooked grains/potato wedges/cooked squash, also salad-big complicated ones with lettuces, tomatoes, broccoli, two kinds of diced pickles, cooked grain, rinsed cooked legumes, assorted chopped vegetables, and a tomato no oil dressing, oat 'cookies' sweetened only with fruit. Our fridge is always packed full. We eat when we are hungry, not at an assigned meal schedule.
The second strategy, is to recognize that in the past we lived to eat but that is not healthy all that focus on eating as the only source of joy in the world. Now we eat to live. We eat completely healthy, for our health, then move on to what gives us joy and happiness in life.
The source of your joy and happiness is where you put in your time. It might be a new hobby, like reading nutritional stuff (which I did for 2+ years), or take up a hobby like painting (which I started in December last year), or do metal detecting or copper hunting (husband's hobby), or put in a big garden (which we do every year), or spend time with the grand children or children, if you have that option, or volunteer in an area you have interest. Find a source of joy and happiness for yourself and stop focusing so much on how this or that meal needs to be the focus of your attention, because it does not need to be that. When you are hungry eat, move on.
So these strategies worked for us, and it wasn't a straight line, it was tough but we did it.
1. Eat to live, move on.
2. Find your source of joy and happiness, focus on that.
