theoretically, if you just give vitamin pills to a 400lb fat guy, could he theroretically live off of his fat/muscle? and if he does, then how long?

Yes, about a year. https://en.m.wikipedia.org/wiki/Angus_Barbieri's_fast

Theoretically, yes — a 400-pound (181 kg) person could survive for a significant period of time on stored body fat **with adequate hydration and essential nutrients (like vitamins, minerals, and electrolytes)**, but there are **limits and risks**. Here's a breakdown of how it might work and how long such a person could survive:

---

### **Theoretical Basis: Living Off Body Fat**

* **Body fat = stored energy**. One pound of body fat contains about **3,500 calories**.
* A 400 lb person might have **150–200 pounds of excess fat**, which is **525,000–700,000 calories**.
* If their daily caloric need while fasting is around **1,800–2,500 calories**, then:

**700,000 ÷ 2,000 = \~350 days** of energy from fat stores alone (in theory).

---

### **Historical Evidence**

* The most famous case is **Angus Barbieri**, a 456-lb man who fasted for **382 days** (with medical supervision), only consuming water, vitamins, and electrolytes.

* He lost **276 pounds** and survived without food.
* Key: **medical monitoring and supplementation** of vitamins, salt, potassium, etc.

---

### **What Would Be Needed**

* **Vitamins:** To prevent deficiencies (like scurvy, beriberi, etc.).
* **Minerals/electrolytes:** Sodium, potassium, magnesium, etc. — critical to avoid heart failure or arrhythmias.
* **Water:** Absolutely essential. Dehydration would be fatal in a few days.
* **Protein:** If not supplemented, the body will **catabolize muscle** to meet essential amino acid needs.

### **Risks and Problems**

1. **Muscle loss:** If protein isn't consumed, the body burns muscle tissue. This includes vital organs like the heart over time.
2. **Electrolyte imbalance:** Can cause fatal heart rhythms or kidney failure.
3. **Gout or uric acid buildup:** From rapid fat breakdown.
4. **Nutrient deficiencies:** Especially if vitamins are not complete (e.g., no B12, C, D).
5. **Refeeding syndrome:** If normal eating is resumed too quickly, it can be fatal.

well no

he ate yeast
probably quite a lot

fresh yeast (the cubes from the supermarket) are about
>~17% protein
dried yeast is
>~48% protein
plus 10% fiber
so nutritionally a great food

and as it's a mushrooms
it has every essential amino acid and pretty good bio availability

isn't surprising he supplemented yeast
that was quite popular for bodybuilders in the 60s to 70s
mostly
>beer yeast
>horse feed yeast
which both are dried and cheaply available in bulk

just remember
>eating too much yeast give you a terrible yeast diarrhea

>>76415938
man, i used to look up to this guy, you just destroyed my childhood. Hes a fraud

>>76415945
Its basically vitamin supplements in the grand scheme of things, I would still consider it a win

>>76415945
>you just destroyed my childhood
just start your own yeast diet

>>76416102
>>76415952
no, i will start my own 1 year fast. And without yeast, just to show the world. Nevermind that my starting weight is what angus weighted when he finished

Wait, is yeast supplementation a thing? I was in the supermarket a few days ago and I considered buying a cube of yeast for microbiome gains, is that a thing?

>>76415945
>>76415952
He also drank tea with milk and sugar.

>cant even survive on body fat alone
>needs stuff that cant be find in nature alone and meat
what the fuck is the point of storing fat then? awful design

>>76416116
>Wait, is yeast supplementation a thing?
not anymore
for good reasons, see >>76415938
but it was really popular from the 1950s to the 1980s

eating like a cube (~50g) of fresh yeast / day probably won't hurt
but if you start scooping dried brewers yeast (for horses, it's cheaper), it's gonna seriously mess with your gut
