We would encourage a controlled carbohydrate approach compared to "low carb" which doesn't have a foundation for amount. That term is what sets people off many times because of arbitrary carbohydrates numbers that don't have any foundation in ratio to total caloric intake.
Let me give an example. In the hospital setting, doctors routinely order 1800 calorie diabetic diets for people that are admitted with diabetes. They pull that number out without knowing if the person is 100 pounds or 300 pounds. The ratio ratio of carbohydrates and need by the body are very different based on body size and type and there isn't a one size fits all approach.
If your Spark plan suggests 1200 calories and you are following a 100 gram carbohydrate diet - that is about 30% of your calories (which is a little lower than recommended level of 40%). That is very different than someone that has a calculated need for 2000 calories and only consumes 100 grams of carbohydrates which only provides 20%.
Carbohydrates are the body's ideal fuel for most functions. They supply the body with the energy needed for the muscles, brain and central nervous system. In fact, the human brain depends exclusively on carbohydrates for its energy. www.sparkpeople.com/resource/nutrition_art
We certainly agree that carbohydrates from fruits, vegetables, beans, dairy products, foods made from whole grain products are favorable over those that include sweeteners such as sugar, honey, molasses, and corn syrup.
We encourage everyone to use those nutrient rich carbohydrate sources to include enough carbohydrate that is no less than 40% of your total calories recommended to ensure your body has all the energy it needs to reach the goals you have set.
