BooJewels, I never thought about how eating foods different from what you're used to might require different enzymes and digestive processes.
Two things helped me when I started the diet: 1) I already ate all the LCHF foods I eat now, both as a child and today as an adult, and 2) I had given up wheat, barley, and rye four years earlier (though I'll always miss rye breads and crackers). Even so, while I ate far less carbs than most people, that still was a huge adjustment. Also, figuring out how to manage my electrolytes. Taking 99 mg potassium with breakfast, and 150 mg magnesium with each meal has helped a lot. At first I had drank salted hot water once a day, but not so much now.
Having a variety of LCHF foods in the house that I liked at all times helped. Adjusting to the different textures of the food was also hard. I missed "crispy" and "rich, creamy" textures the most. Every few nights I'd cheat and eat three to four corn chips topped with melted cheddar cheese, or not cheat and have a slice of ham wrapped around cream cheese with a dill pickle slice. Drinking green tea between meals took away the need to overeat, and green olives helped when I repeatedly would open the refridgerator door with the need to eat "something".
I think if I didn't already like meats, cheeses, and butter, this would have been a lot harder, and it was hard enough. When I went on the diet, I was eating a potato in one form or another at least once a day. Not sure which was harder, giving up bread or potato, or sweet potato...ah, those wonderful starchy sugars.
Googlegoss, hope you get through the adjustment soon.
