So I've been on a low carb plan(not too low, 50-100g carbs/day from oatmeal, fruits, veggies ketchup , but still low for me considering my past eating habits) for about 3 days now, my headaches are barely noticeable, today its all good, no pains. I haven't noticed it yet but I've heard that some people feel sluggish if they eat a lot of carbs throughout the day. Does this apply to anyone here? I guess 100g carbs isnt low enough for me to experience total change, but I definitely feel a little better now that I don't eat so many cookies, pizza, etc. The only time I felt sluggish is eating total junk food throughout the day. What's your opinion?
