Intensifying the duration or frequency of your fasting regimen may improve the chances of getting results. Undertake shorter fasts more often. Extend a longer fast. Often it is useful to do a longer fast on a regular basis, say every three to six months. Or make your fast stricter, say, by shifting from a bone broth fast to a water-only fast. If you find fasting difficult, it can be useful to closely monitor your diet and try to lower your dietary carbohydrates further.
