Low Carbs or controlled carbs or counting carbs - there are many levels and finding the level you need should be successful for anyone, if they want it to be. It is just that your level of how many carbs per meal may not be the same as mine. For instance, if I were to eat two slices of bread with my breakfast as you mention you do, my blood sugar reading would be too high. Also, if one eats too much protein while doing low carbs, this can upset the numbers as well. It also matters how much fiber and fat you eat along with the carbs. Some people might get away with more carbs if they eat them with some healthy fat and fiber. I guess finding a system that works for an individual is what's most important, but counting carbs, a method using low carbs can work for any and everybody if they look into it and understand all the factors and are motivated to use it correctly. It takes determination to count and measure and weigh until you get the hang of it. Sure, I'd rather eat as much fruit as I want, but that would not be low carbs, would it, and it would raise my numbers.
