The Snake Diet, popularised by Cole Robinson on YouTube, advocates extended dry and water fasts combined with a specific electrolyte mixture (“snake juice”) and aggressive language around weight loss. The community has a devoted following and produces dramatic before/after results. It also includes practices that range from reasonable to genuinely dangerous, often without distinguishing between them. This guide is safety-focused: which elements have legitimate use, which are risky, and what to know if you’re considering trying any of it.

What the Snake Diet Is
Core elements of the Snake Diet community’s recommendations:
- Extended water fasts (often 3-7+ days)
- “Snake juice” — a specific electrolyte mix using salt, potassium chloride, magnesium, and sometimes baking soda
- Daily 23:1 eating windows or longer between extended fasts
- Periodic dry fasts (no water) of variable length
- Aggressive marketing language around obesity, willpower, and food behaviour
- One large meal of mostly meat and fat when eating
The Snake Juice Recipe
The widely-used recipe (per litre of water):
- 2 grams salt (sodium chloride)
- 1 gram no-salt (potassium chloride)
- 0.5 grams magnesium sulfate (Epsom salt) or magnesium chloride
- Sometimes a small amount of food-grade baking soda
This is essentially a homemade electrolyte solution, similar to what’s recommended by mainstream extended-fasting protocols. The recipe itself is reasonable. The use case (multi-day water fasts) is where the safety questions arise.
What’s Reasonable
- The electrolyte mix recipe (snake juice approximates standard fasting electrolyte protocols)
- Single 24-48 hour water fasts in healthy adults
- Daily intermittent fasting (16:8, OMAD)
- Recognition that obesity is serious and aggressive intervention may be appropriate
- Emphasis on electrolyte adequacy during fasts
What’s Risky
- Multi-day water fasts (3+ days) without medical supervision
- Dismissing concerns about disordered eating
- Promoting fasting through hunger that’s become alarming
- Aggressive shaming language directed at obesity
- Fasting protocols recommended without screening for contraindications
- Extended fasts in people on medications (especially diabetes, blood pressure, anticoagulants)
- The general framing that more fasting is always better
What’s Genuinely Dangerous
- Extended fasting in people with eating disorders. The community attracts people who are using fasting to suppress eating in disordered patterns, and the framing reinforces these patterns.
- Multi-day fasts in adolescents and young adults. Real cases exist of teenagers attempting extended Snake Diet fasts with serious medical consequences.
- Dry fasting beyond 16-24 hours. Real risk of dangerous dehydration and kidney injury.
- Aggressive refeeding after multi-day fasts. Refeeding syndrome is real and the community rarely emphasises careful refeeding.
- Fasts in people with type 1 diabetes following internet protocols. Risk of severe hypoglycaemia and DKA.
- The implicit message that medical supervision is unnecessary. For multi-day fasts, in chronic conditions, on medications — this is wrong.
- The pattern of using extended fasts to compensate for binge eating. Reinforces disordered cycles.
Dry Fasting Specifically
Dry fasting (no water) gets specific advocacy in the Snake Diet community. The honest medical position:
- Brief dry fasts (under 16 hours) are normal — most people don’t drink overnight
- Religious dry fasting traditions (Ramadan during daylight hours) have been practised for centuries with mostly safe outcomes in healthy adults
- Dry fasts beyond 16-24 hours carry meaningful risks: kidney injury, severe dehydration, electrolyte derangement, syncope
- The claimed benefits (faster autophagy, deeper fat loss) are not supported by significant evidence
- The risks scale faster than the benefits as duration extends
For most people, water fasting is the rational endpoint of strict fasting. Adding dry fasting on top is risk without proportional benefit.
Refeeding After Long Fasts
Refeeding syndrome — the rapid intracellular shift of electrolytes when food returns after prolonged fasting — is a real medical risk and the area where the Snake Diet community most commonly fails to communicate adequate caution.
For fasts of 3-5+ days:
- Start with broth and tiny portions (a few bites)
- Wait 2-3 hours between small meals
- Day 1 total: 30-50% of normal calories
- Days 2-3: gradually increase
- Avoid: large refeeding meals, refined carbohydrates, alcohol
For fasts of 5+ days, refeeding should ideally have medical input. See our refeeding recipes and safety guide.
A Safer Version
If you’re drawn to the Snake Diet’s appeal but want to avoid the dangerous elements, the safer version:
- Use the snake juice recipe — it’s reasonable
- Limit individual fasts to 36-48 hours unless under medical supervision
- Get medical input before any fast longer than 48 hours
- Use careful refeeding after any fast over 48 hours
- Skip dry fasting entirely
- Address eating patterns through behavioural support, not punishment fasts
- Track health markers, not just weight
- Work with a doctor on chronic conditions and medication adjustments
Frequently Asked Questions
Is snake juice safe?
The recipe is fine and approximates standard extended-fasting electrolyte protocols. The application (extended water fasting) is where individual safety considerations apply.
Can dry fasting really increase autophagy?
The mechanistic claims are speculative; the human evidence for benefit beyond water fasting is weak. The risks (kidney injury, severe dehydration) are real and well-established.
I’ve seen impressive Snake Diet results. Should I try it?
Aggressive caloric restriction works for weight loss whether labelled Snake Diet or anything else. The results are real; the methods used to achieve them range from reasonable to risky. You can get the results with safer methods.
What if I’m severely obese and need aggressive intervention?
Discuss with a doctor. Medical fasting programs exist (operating under medical supervision) for severe obesity and have better safety profiles than self-directed extended fasting based on internet content.
Is the language “tough love” or just harmful?
Subjective. Objectively, there’s no clinical evidence that aggressive shaming language improves long-term weight outcomes. There is evidence that it harms people with eating disorder vulnerability.
Can I lose weight as fast on safer protocols?
Slightly slower, often. The trade-off is sustainability and safety. Faster initial loss often regains; slower loss with sustainable practice tends to last.
The Bottom Line
The Snake Diet contains some reasonable elements (electrolyte mix, recognition that aggressive intervention may be needed for severe obesity) packaged with risky practices (frequent multi-day water fasts without supervision, dry fasting, casual approach to refeeding) and harmful framing (shaming language, dismissing eating disorders). The reasonable elements can be extracted; the risky and harmful ones should be left out. For aggressive weight loss, medical fasting programs and careful self-directed protocols both produce results without the safety concerns.
