Looking at your stats you likely lost around 2.5 Lbs of fat and muscle combined so far in 6 days.
It would take you over 80 days to fast to get to 140 lbs. That’s of course not reasonable but even 20 days will get you down only 9 Lbs.
You see that fasting is not very sustainable as primary weight loss regimen. However fast is very effective to jump start a weight loss program.
Well ideally you would be drinking plain water. I’ve actually never fasted while drinking zero Gatorade, and creamer, or la Croix. I have done black coffee while fasting, I’ve seen a few sources say that there is a fat burning benefit to it.
Now I understand completely that there is usually nothing wrong with using fasting for weight loss. My concern is however is that you are using extended bouts of fasting to drop weight very quickly with certain expectations.
TLDR: Stick to 36-48 hour fasts, This will help maintain muscle tissue which is essential in maintaining metabolic health/Speed, while gaining the metabolic benefits of norepinephrine. ADF is perfect for this ebb and flow eat up to +10% of maintenance on your eating day. Again think in months or you will screw yourself over
Depending on what you have to lose, weight loss, ideally the loss of fat only is a process that takes months, yes, months to see significant progress. Now if you are leaner bodied ( I am an idiot don’t know how to read the your stats) you could potentially see progress with-in weeks.
Next is a mixture of Bioscience and studies that have researched metabolism and extended fasting.
Almost all of the literature I have seen, states that after 36-48 hours the metabolic boost from norepinephrine and adrenaline levels out. If I remember correctly it is a benefit of around and up to 10% which is considered statistically significant.
Extended Fasting may offer benefits associated with autophagy and the regeneration of T-cells within the body. T-Cells migrate back into the bone marrow where they then receive immune system boosting benefits. During this time however you are much more vulnerable to infection due to the transient immune suppression from absent T-cells within your circulating blood supply.

My personal opinion based on what I understand is starting a regime that:
Allows you to reach that 36-48 hour window, to obtain the metabolic benefits of the bodies hormone response but not significantly deplete your EAA levels within the blood.
Essential Amino Acids are unable to be synthesized by any biological process with-in the body. If you don’t get them through food or supplements you are screwed, basically. The reason this is important is because these EAA’s are vital to maintaining your muscle tissue. HGH is released into the blood as fasting length increases up to around 300% in some instances. HGH helps to maintain muscle mass while fasting, but only up to a point. After that the body has no choice but to catabolize protein tissues (muscles then organs eventually) to feed the brain (BCAA will be responsible for this because they can be synthesized by biological processes, not necessary the EAAs) Many say that you can build muscle while fasting but thats only partially true.
Its only applicable to newbie trainers and individuals with high amounts of available stores energy reserves. Otherwise Insulin Growth Factor or IGF1 is heavily suppressed during extended fasts. IGF1 is vital to muscle protein synthesis or the creation of new muscle fiberd. So you may gain some muscle but the hormone profile in the blood isn’t exactly condusive to the process.
Ok so rambling over. Thankfully lol.
Flavcity with Bobby Parrish < that guy has great info, focus on the brands of food he is recommending. If you are eating like garbage on your eating days you are killing your fat loss gains. Bleaches, hydrogenated oils assault your microbiome and cell membranes, bad for health and fat loss.
If you have any further questions I would be glad to share what I understand on the topic.
