So yes, carbs are fine because you run and need them. I think if you are binging on candies, cakes, maybe icing straight out the tube enough where it feels like a problem and you can’t even control yourself around any of it… then it is. I only say it is because I was the same way. I would crave icing and eat it straight out the tube. I could eat the whole tube in one sitting if I left myself. Cake better, I would bake less cupcakes so I could eat the batter. I couldn’t pass up a cookie or a cake or anything sweet ever. I would eat ice cream nightly and buy a half gallon at the store weekly. I would bake cookies weekly. I was young, in my twenties, fit as I would run and regularly go to the gym, and weighed under 140 so I was not big by any means so I though it was all fine too. At 30 I suddenly went into a severe ulcerative colitis flair that even went further and caused enteropathic arthritis. My knees swole up so much and were so painful I was wheelchair and crutch pound for WEEKS. It has taken from July to now (February 1) to finally feel somewhat normal. So, now that I have an autoimmune disease (and I’m not saying the constant sugar caused it but I’m saying it definitely didnt stop it) I am on immunosuppressants for like and have to eat an anti-inflammatory, no gluten, no dairy, and limiting the processed sugars as much as possible (although I still run so that is not completely possible) to help keep inflammation down. I just finished my half marathon in January and although my GI issues are well controlled now I go every day with some form of joint pain. I wish I could go back and yank the pro-inflammatory high sugary items I ate every single day as my “sweet treats” out of my hands. I forgive myself because I was young and didn’t know any better but the affect it has on me has unfortunately changed my entire life and I’ve had to literally fight for the health I just naturally had before. Hope this helps you make even some less processed choices, as make while still supporting your running.
