Yep, sometimes the body is in such starvation mode! Changing the food works when that happens...and sometimes you just need the extra nutrients.
I prepare really low-fat meals, so I try to make sure I get some lean red meat, lots of dairy (mostly yogurt) and fatty fish in my diet every week.
And another trick I have is adding a tablespoon or two of walnut pieces to my salads...it's a good plant source of those oils we need, boosts the protein, and helps keep things lubricated.
This is a typical diet when I am eating on my "good days" when I reach my target calories:
My favorite breakfast is one carb delight smoothie (non-fat cultured milk smoothie at 60 calories), a Jennie-O's turkey burger on two slices of Orowheat light bread with some yellow mustard.
A nice salad for lunch...mixed greens with either some salmon (about a quarter cup) or feta cheese, and a tablespoon of walnut pieces, some chopped olives, maybe some onion, and a non-fat vinegrette. Another one of those smoothies. A chewable calcium supplement.
Dinner might be a small piece of steak broiled, with steamed green veggies, rice or potatoes, or perhaps spaghetti with some jennie-O turkey italian sausage, or just marinara with a thin piece of roast beef and a salad. Always a carb dish. Preferably a high fiber veggie, like brocolli. Usually meat, but sometimes beans. I like to buy the Barilla plus pasta because it has extra protein and is multigrain. Fruit for dessert - berries, perhaps, or light canned pears, or something.
And then there are days this is just too much for me, and I eat less. I'll only have the smoothie and coffee for breakfast, for instance, and a small salad for lunch. I'll go all day on 500 calories and then eat 400 calories at dinner or less. If I eat less too many days in a row, I feel it. Then back to the higher counts, at least once or twice a week, even if I have to make myself. And frequently, it's the day after I do that that I drop the weight.
It surely gets hard juggling wanting to lose with eating well...for me it can be a real struggle, especially getting fruit in my diet. Right now, I should be eating lunch. So what am I doing? Posting! But I did have my big breakfast.
