Totally agree with you Going gluten-free was a necessity for me, but it also changed my lifestyle for the best. Before I went gluten-free my eating habits were bad, I ate whatever I wanted, whenever I wanted. When I rented my own place I gained nearly 10 kgs in one year (22 lbs). Going gluten-free made me have to plan my meals and choosing healthier options. A lot of junk/comfort foods I used to eat are either unavailable now or hard to come by and expensive. No more snacks on the go or stopping somewhere for coffee and cake. Cooking also changed: I can't use pre-fab stuff like sauces and spicemixes so I have to cook my own. These are tastier, contain less salt and no flavour enhancers.
Going gluten-free also gives me the energy to exercise, I'm totally addicted to strength training now People often think that going gluten-free is very difficult and restrictive, they hardly see the positive side of it. As a matter of fact: I wouldn't want to go back to gluten even if I could.
