A 2015 study from the Annals of Internal Medicine showed that for those who have a hard time following a strict diet, simplifying the weight loss approach by just increasing fiber intake can still lead to weight loss. Women should aim for at least 25 grams of fiber per day (based on a 2,000-calorie) diet, according to the most recent U.S. Dietary Guidelines. Start with our high-fiber diet plan.
But before you set out to follow this weight-loss regime, you should know that you are not going to lose pure body fat. Due to the calorie deficit required to burn each kilo of fat, it is not possible to lose 4.5 kg of pure body fat in just one week. Although a lot of the weight you lose will certainly comprise body fat, you will tend to shed kilos by dropping excess water weight from your body. This is because the plan involves lowering your insulin levels and ridding your body of stored carbs that hold water.
Ideally, health experts recommend that you aim for a loss of 1 to 2 pounds a week (7 days). Aiming to lose 2 pounds in a day is extreme and potentially dangerous; it is neither recommended nor guaranteed as an outcome. However, there are unusual times when a person considers this necessary, such as before a weigh-in for sports, so there are plans for achieving this in existence for those rare, one-off occasions. For details on this topic, see How to Lose 2 Pounds in One Day.
