Consider a colon cleanse, then a liver/ gall bladder cleanse. That will help restart your system and will take off some weight right away.
What are you doing for excercise?
Are you eating tons of nuts and sugars???

Maybe what I should find out about is...
what have you been doing in between time? Could it be that something you've either been doing, or else not doing, has had some effect on the metabolism that's changed things around some. Think.

The older we get, the more difficult it is to release weight, in my experience. I did the raw diet two years ago and easily released 30 lbs in 4 months eating as much as I wanted. I was never hungry.

This time, I'm 58 and it seems more difficult. It took more time to start the lbs releasing. (I read that we should condition our minds to release weight--not lose it. When we lose something, we're constantly trying to find it again, subconsciously speaking.) But in 3.5 weeks now, I've released 7.5 lbs. I am letting myself go hungry more this time. I have a tendency to eat too much at night and I'm trying to curb that. Plus, all my usual favorite things to eat like cheese and crackers are gone from my apartment now.

As for colon cleansing, I like Jon Barron's product, Colon Correction. His company is called Baseline Nutritionals. It's gentle, works every time, and seems safe to use daily, if needed. It strengthens the colon. He also has various herbal products of very high quality for cleansing. I've been using this product for a long time, so perhaps this is why I don't have problems going 100% raw instantly

I eat 3 fruits in the morning: 1 small apple, 1 Valencia orange because I like them juicy, and some strawbs or blubes or kiwi. I tend to need 3 TBS of ground flax or some chopped nuts on top because I'm pre-diabetic and the sugars in the fruits seem to be too much without some mitigating protein. I know this is bad food combining, but I don't notice any problems from it.

I have a very large mixed green salad that includes lots of sprouts--alfalfa, pea sprouts, mung bean, and/or sunflower sprouts. It has shredded carrot, shredded beets on occasion, romaine, spinach, shredded cabbage, avocado, sometimes pumpkin seeds, dulse, broccoli, and dressing.

Dinner is a hodgepodge. Maybe I'll make a smoothie, or maybe marinara sauce over zucchini noodles, or a green soup made with sprouts, etc.or I just eat a bunch of flax crackers. I eat olives or dates sometimes later when I still feel hungry. Or a handful of goji berries, or a handful of nuts.

This might be a high fat diet, but I seem to need it or I get that hypo-glycemic reaction.
