In case you are wondering how a carb stacks up to a gram of fat or of protein: 1 gram of protein = 4 calories. 1 gram of fat = 9 calories. A Better Answer: 50-100 grams per day for weight loss and 100-150 to maintain weight. Following the recommendation from the USDA on how many carbs to eat everyday would probably result in weight gain and at the least in not losing weight â assuming you were eating the right amounts of other foods. By sticking with 50-100 grams of carbs a day, you can still lose weight and do so in a much more healthy and reasonable fashion.
