Dry fasting is a more advanced variant of intermittent fasting in which you avoid not only calories but also drinks and water. Soft dry fasts permit skin contact with water, whereas severe dry fasts forbid it entirely.
Dry fasting provides all of the health benefits of regular water fasting, but there is also evidence that it stimulates autophagy considerably faster and more effectively.

Does Dry Fasting Boost Autophagy?
During a dry fast, the body begins to collect water from the cells. H20 molecules makeup around 60% of your body and are the primary component of muscle, tissues, and organs.
Burning fatty acids, known as beta-oxidation, produces metabolic water by releasing hydrogen atoms from glycerol. The backbone of triglycerides, which are fat energy molecules present in adipose tissue, is glycerol. Even if you don’t drink or eat anything, you’ll eventually obtain access to water. Desert animals in nature, such as camels, survive by burning fat for fuel.

Cell dryness suppresses mTOR signaling while boosting AMPK, which is required for increased autophagy[i]. As a result of the increased energy stress, dry fasting will trigger autophagy.
A 5-day dry fast was safe, enhanced renal function, decreased body weight, and all circumferences in 10 healthy subjects[ii]. Short periods of dehydration and deliberate dry fasting strengthen the body through hormesis and fat adaption.
Is Dry Fasting More Effective Than Water Fasting?
Water fasting and dry fasting both raise glucagon concentrations, ketosis rates, and metabolic acidosis[iii]. Dry fasting, on the other hand, can promote hyperglycemia, whereas water fasting causes lower glucose levels.
Cortisol and glucagon levels may be higher during a dry fast than when drinking water because the body must break down more of its fuel to make energy. This will result in increased fat oxidation and may be increased autophagy.
Cancer and bacteria are both living creatures that require energy to survive. Because of autophagy and hunger, water fasting has reduced carcinogenesis and combat tumors[iv]. Dry fasting also removes water from malignant cells, hastening their demise.
Symptoms of Fasting Detox
Another advantage of dry fasting is that you will be more protected against detox symptoms. Your adipose tissue tends to accumulate poisons and inflammatory chemicals.
During a water fast, you release them into your bloodstream and eliminate them via urine, liver, and kidney filtration. This may result in unpleasant detox symptoms such as nausea, diarrhea, or tiredness.
On the other hand, dry fasting will burn up all of the energy in the cell, including the toxins, rather than excreting them. As a result, you avoid the filtration process that occurs during water fasting.
At the same time, water fasting can assist in eliminating toxins more quickly and frequently because urination, sweating, and liquid excretion all wipe away some toxins and illnesses. If you are dehydrated for an extended period, you may experience constipation and delayed bowel motions until you rehydrate appropriately.
Deuterium Depleted Water for Dry Fasting
The body can produce around 110 grams of water for every 100 grams of fat, compared to 60 grams of carbohydrates and 42 grams of protein[v]. As a result, burning your adipose tissue is a very effective survival adaption during times of dehydration and energy deprivation.
Deuterium is depleted in the metabolic water produced during beta-oxidation, which supports mitochondrial function and health. Water consumed by deuterium also prevents cancer growth and regulates the cell cycle.
