But for me, artificial sweeteners (AS) are really hard on me, just like sugar! Maybe it's bad for you, too. Many folks are incredibly sensitive to AS.
Also, even tho I do eat bacon and sometimes sausage, they DO tend to stall me a bit and I'm certian it's b/c of the sugar that they are cured with. Also, the excessive (but YUMMY saltiness).
I also avoid as much as possible wheat. Bloatsville for ol' Betty.
Of course, it took trial and error to figure this stuff out.
I have found for myself (again YMMV) that I do a lot better when I omit added carbs from my breakfast and lunch and just add them to dinner or perhaps a snack, too, sometimes.
For instance, I have a red pepper with breakfast or some lettuce, and for lunch I may have a salad, but I only add in the starchy (sugary) carbs at dinner. I'll have some berries with cream, like you, no AS, or some other piece of fruit, etc.
I have found this system is working for me. I've really limited the starchy carbs, upped the non-starchy like greens, and VIOLA! I'm in the mix and feeling great.
May work for you, may not. We are all different, right? I would suggest eliminating the AS, the wheat (have 1/4 cup--measured dry--whole oatmeal instead perhaps?) one at a time and see what happens for a week or two.
And as Lisa said, past dieting history can determine how your body will act on a healing plan such as SP. Also, you may indeed need more calories from fat and protein sources.
Wishing you all the best!
