Thin 0. 1 kg, strictly speaking, can be considered thin, but the amount of thin is small, which may be difficult to detect. One kilogram is 500 grams, so reducing 0. 1 kg is equivalent to reducing 50 grams. Our weight will fluctuate due to the changes of water, food and other factors, so the change of losing 0. 1 kg can not fully reflect the reduction of body fat. If you want to lose weight more obviously, you need to continue proper exercise and reasonable diet planning to achieve long-term stable and healthy weight loss.
