Rye bread is so much more filling than regular white or even regular wholegrain bread. It's packed with fibre and has a lower GI, so you'll keep those blood sugar levels on an even keel.
These slices are based on a slice of rye bread coming in at 100 calories. You can buy rye breads ready-sliced at roughly this calorie count, which makes the whole process so much easier.
Although these make a great breakfast, you can really eat them any time of day when you need a low-calorie flavour hit.
