I am prediabetic and not low carbing but am reducing carbs somewhat. Breakfast is a really difficult meal for me I hate cereal, museli and granola and certainly could not face fruit or smoothies for breakfast.
I love eggs but not sure how many I should eat in a week
As many as you want to eat. An important part of any sustainable diet is to eat things you want to eat.
I do have raised cholesterol and eat low fat foods so my breakfasts at the moment are really just cold meats with tomatoes cucumber etc most days and eggs a couple of times a week as omlettes or scrambled with mushrooms cheese and tomatoes
Chicken eggs are actually fairly low in cholesterol. You'd need to eat something at least 5 a day before you'd be anywhere near the amount of cholesterol the average needs. You don't mention what your "raised cholesterol level" actually is and it may be reduced more by reducing carbohydrates.
