yes you can, you just need to ensure the fat percentage of your meal is ideally below 5%. if you read your menu suggestions in your booklet then you'll see eggs are included. One, for example, is a poached or dry fried egg on a slice of bread with a grill tomato - the tomato brings the overall percentage below 5%.
You can't control the amount of fat in meat fish eggs so, as long the meat is very lean you can ignore the 5% rule.
All fresh produce eg fresh fruit and veg is fine as obviously they don't contain any fat.
Now this is where you have to apply the 5% rule - on manufactured/processed foods. Basicaly if it comes in a packet/box etc it will have the fat content on the nutritional value panel. You need to look at the fat line and if it is 5% or more per 100 grams - not per serving, then trya and avoid it. Look for alternatives in the same line of food eg yogurts as they will all differ. It takes a bit of time doing the shopping to start with because you are reading the packets but once you know which ones to buy and like, its becomes second nature. Hope this helps a little, please don't start thinking its going to complicated, it isn't.
