My sister is trying to convince me to do "carb cycling". I can't do low carb. I exercise a lot and I need minimum 100g a day of carbs. I choose to get most of my carbs from beans, veggies, boiled barley and spelt, and fruits. I'm also a little below my ideal weight, so I'm not looking to lose. I can't do low carb because I think it's too restrictive. I figure as long as you aren't eating many simple carbs and getting mostly starches and fiber as carb sources, you are fine. And I can sustain it and have energy. Low carb makes me grumpy, want to binge, and leaves me feeling exhausted. I suppose if I were more sedentary it'd be better, but I'd much rather stay active and eat my carbs.
