Carbs are really what gets most people in trouble food/weight wise.
Most Americans eat between 250 and 300 grams of carbohydrates a day, the equivalent of 1,000 to 1,200 calories. The Institute of Medicine, which sets dietary nutrient requirements, recommends 130 grams a day. Some, such as Dr. Frank Hu, professor of nutrition and epidemiology at the Harvard School of Public Health, say achieving that would be a big step in the right direction, but other low-carb advocates believe the number is too inflexible.
“What people can tolerate varies widely based on age, metabolism, activity level, body size and gender,” says Dr. Stephen Phinney, nutritional biochemist and an emeritus professor of UC Davis. For healthy adults the number can be higher, he says, while others will feel and function better if they stay between 50 and 100 grams a day. “I’ve seen some people get in trouble when they eat over 25 grams.
