Dry Fasting Turns Fat Cells into Water in 16 Hours

DeLauer emphasizes that going into a dry fast already dehydrated is like 'torture ourselves'—the goal isn't to suffer unnecessarily. By loading sodium and water beforehand, you give your body a reservoir to draw from while metabolic water production ramps up. He acknowledges that during fasting, insulin is low and the body excretes more water anyway, so sodium helps retain that pre-loaded water. He recommends Element because it provides a precise 1,000 mg of sodium per serving, making it easier to dose. He states that during a regular water fast, he's a fan of electrolytes, but for a dry fast, the logic is to hydrate prior. This protocol is a harm-reduction strategy rather than a performance enhancer.

After comparing various fasting protocols, DeLauer reveals that despite being advanced in dry fasting, the method that actually gets him leanest fastest is protein sparing modified fasting. He describes it as dropping fats and carbs while eating just lean protein at a very low calorie level for two days straight. He references that PSMF has been used in research to get people very lean very fast. He contrasts it with dry fasting, noting that with PSMF you stay hydrated and have protein, which prevents the body from breaking down muscle tissue. He asserts that dry fasting works, but he seems to favor PSMF as a more sustainable, safer tool for body composition. This recommendation is pragmatic: he has tried everything and lands on this as the most effective fat loss protocol.

DeLauer explains that fat tissue contains hydrogen. When the body oxidizes fat for energy, that hydrogen is liberated and can bind with inhaled oxygen to create H2O molecules—what he calls 'molecular water.' He acknowledges that some proponents claim this internal water is 'cleaner' because it bypasses filtration, but he pushes back: at the cellular level, water is water, and the cleanliness distinction is overstated. The real significance, he argues, is that the body literally turns fat into water, which is 'really cool' but does not instantly make dry fasting superior. He cautions that people who are chronically well-hydrated may be less adapted to generating metabolic water efficiently, whereas those who occasionally go without water (like during Ramadan) might have better adaptive mechanisms. There are also anecdotes of individuals gaining weight during short dry fasts because the body holds onto the metabolic water it produces as a survival response to perceived dehydration.

DeLauer outlines the concept of a 'cellular pressure gradient'—the change in polarization and mineral concentration due to dehydration creates a pressure differential that pushes broken cellular components and debris out of cells and into the interstitial space. He suggests this could speed up the clearance of dysfunctional parts, essentially ramping up autophagy beyond what nutrient fasting alone achieves. However, he immediately tempers this by stating that 'we don't have tons of evidence to really support it all the way' and that it's 'speculated.' He also notes that if someone carries a high toxic burden stored in fat, the accelerated release during dry fasting can make them feel 'really cruddy'—a potentially expected detox reaction. This is a double-edged sword: faster cleanup but potentially more intense side effects.

DeLauer explains that during fasting, ketone production rises. In water fasting, you can excrete excess ketones via urine, but dry fasting eliminates this route, causing ketone levels to spike faster. He quotes a timeline: ketoacidosis can occur around 3 days of dry fasting, compared to 9–11 days with water. He quickly adds that this mainly affects people with an underlying metabolic derangement, but the risk exists. This is a key differentiator between the two fasting methods and a reason he considers dry fasting advanced.

After detailing the science and potential upsides of dry fasting, DeLauer pivots: 'I think you're going to get a similar effect just fasting with some water and electrolytes.' He suggests that the accelerated fat loss claims may be offset by risks and discomfort. He notes that he personally has dry fasted and is 'pretty advanced with it,' but doesn't see it as necessary. He recommends people consider water fasting with electrolyte support and possibly protein-sparing modified fasting for fat loss, which he argues is safer and preserves muscle. This stance is notable because he is known for exploring extreme protocols but here he dials back, emphasizing that dry fasting is more about spiritual connection than metabolic advantage.
