What is dietary fiber powder? It is a substance that can act on human intestine, further promote the reproduction of intestinal beneficial bacteria and inhibit the reproduction of intestinal harmful bacteria. Its existence can make the intestinal peristalsis faster, and the toxins in the human body are naturally excreted faster, so that the nutrients ingested by the human body can be fully utilized. Therefore, if properly ingested, it will gradually lose weight due to the discharge of toxins. However, it should be reminded that if you want to see more obvious slimming changes, you must grasp the intake in place, because if you consume too much of any substance, these substances themselves have certain energy. Once you eat too much, the energy you consume will be far greater than the calories you consume, further causing energy accumulation and obesity. The above is a personal answer about whether dietary fiber powder can lose weight. Generally speaking, proper intake of dietary fiber powder can promote the discharge of toxins and further achieve the purpose of slimming. The slimming effect is very obvious, but the amount must be controlled.
