Let's bring things into perspective.
No matter what kind of starch-rich or protein concentration you can bring to the table, cells cannot divide fast enough in a given day to achieve 1in of length unless you completely destroy the penile tissues to the point of no return. Nerves and blood vessels cannot break down and heal fast enough to establish functional pathways in 24-hour period, or even 100-hour period to establish biological significant integration without destroying cellular establishment permanently. There is no quantum-level generative methodology through amassing bioavailable resources and breaking down fast enough for the body to provide energy-rich integration by cellular consumption and processing through the constant high-anthropic principle to grow 1-inch per day, or even overlapping 0.5-inch per day. Cellular subatomic stabilization after antropic states can be achieved through cancerous growth style, where 0.35-inch per day can be achieved. However, by the end of the 17-day period, you will have one elephant-sized penis that looks like a limped and disfigured noodle known in the medical world as giant cell tumors (GCTs). Yes, it also happened for penises.
Ingesting "MASSIVE" amounts of these foods can also create phyto-toxicity that the body cannot process fast enough. Most of the solids will be secreted as wastes. Most of the "extracted" contents in juice form will also be secreted by the body due to biological rejection because the body cannot absorb fast enough. If you want medical and biochemistry publications on the biological absorption rates for human across the world, I can provide that for you. You can eat all you want 24 hours a day, 7 days a week, for the next 17 days, but all will come out as massive waste. High concentrations of carrots and broccoli will spike specific heavy metals that will indeed kill you, if they don't give you either diarrhea or constipation. Milk proteins will block carrots, broccoli, and beet beneficial minerals absorption up to 80%, while the high fiber contents strip the protein loading and complex sugars from your system. Why do you think dieticians have specific dietary plans for certain groups of males and females pursuing different things? Dieticians have not just suddenly appeared since the 1980s because there was not enough field of studies to scam the world.
You can create "super pills" or "super supplements", or simply snake oils or scam products, to promote explosive growth like the rest of the world's products introduced since the 1100s. But I'll stop here. Again. Pursue this endeavor with a large jar of salt at the ready. If you're hooked on purchasing a "plan" or "method", I wish you luck. Do stay on top with logical reasoning.
