Primal Potato Diet (PPD)
Time for a new thread on potatoes for weight loss.

Healthy weight loss != mostly water weight loss + muscle catabolism?
Uhh, no. water loss is what happen when you go LC.. Potatoes are the ultimate carbs so rather a water gain, no?

!= does not mean equals....

Without fat, bulk calories are stored as glycogen, excepting that there is a little de novo fat synthesis from glucose in the liver. Hepatic glycogen does not cause hepatic insulin resistance. In the near absence of FFA supply the liver maintains insulin sensitivity and the ability to degrade insulin. Nothing like as much insulin reaches the periphery as is produced by the pancreas in response to 2-3000kcal of potatoes.

The ultimate determinant of weight loss is fasting insulin. This determines how much lipolysis occurs during the period before the next meal. No one expects to lose weight during the 4 hours immediately after any meal. The following 8 hours, especially overnight, is when weight loss occurs. (Peter from Hyperlipid)

Hello all. I joined this forum to talk about the Potato diet. Specifically the use of adding a significant amount of coconut oil to AID in the amount of fat loss. I know the original calls for no fat because of the mechanisms to produce insulin need a fat source and body fat is the source on this diet BUT as has been discussed, MCT is metabolized differently in the body and is treated more like a carbohydrate. Coconut oil also has been showed to raise metabolism so if on a caloric deficit where all MCT is being burned along with the starch, would that not equal a higher rate of fat loss without messing with the mechanisms at play?
I am still not exactly clear on if this would help or hinder and all potato diet but i find it a very interesting idea, not only because it would add a much needed variety to this diet but also that it could potentially be a better version! Here are a few things pulled from different sources.
" Medium chain triglycerides are digested and utilized differently than other fatty acids. Instead of being packaged into lipoproteins that circulate in the bloodstream, they are absorbed directly into the bloodstream through the portal vein, and are then transported to the liver. Because they don’t need bile or pancreatic enzymes to break down, they are easier to digest. And because they are easier to digest, they provide your body with quick energy, like carbohydrates.
Since MCTs are utilized quickly as energy, they are not stored as fat—unless of course you over consume calories. Numerous studies have shown that ingesting MCTs contributes to weight loss and a reduction in fat."
"The ability of some of the medium chain saturated fatty acids to inhibit the liver's formation of fat very likely synergizes with the pro-thyroid effect, in allowing energy to be used, rather than stored. When fat isn't formed from carbohydrate, the sugar is available for use, or for storage as glycogen. Therefore, shifting from unsaturated fats in foods to coconut oil involves several anti-stress processes, reducing our need for the adrenal hormones. Decreased blood sugar is a basic signal for the release of adrenal hormones. Unsaturated oil tends to lower the blood sugar in at least three basic ways. It damages mitochondria, causing respiration to be uncoupled from energy production, meaning that fuel is burned without useful effect. It suppresses the activity of the respiratory enzyme (directly, 'and through its anti-thyroid actions), decreasing the respiratory production of energy. And it tends to direct carbohydrate into fat production, making both stress and obesity more probable. For those of us who use coconut oil consistently, one of the most noticeable changes is the ability to go for several hours without eating, and to feel hungry without having symptoms of hypoglycemia."
"Medium chain fatty acids (MCFA) are readily oxidized in the liver. Animal and human studies have shown that the fast rate of oxidation of MCFA leads to greater energy expenditure (EE). Most animal studies have also demonstrated that the greater EE with MCFA relative to long-chain fatty acids (LCFA) results in less body weight gain and decreased size of fat depots after several months of consumption. Furthermore, both animal and human trials suggest a greater satiating effect of medium-chain triglycerides (MCT) compared with long-chain triglycerides (LCT). "

Hey, Zach - Welcome to the fray! Here's the real problem with the "Potato Diet"...as soon as you do it once, you are an instant expert. It only takes 2 weeks or less to go from a non-believer to a guru. Richard at freetheanimal is living proof.

Good idea, as the other thread has become ridiculously long - and somewhat heated in places.
I think this PPD has already proven itself successful for most people and it's worth taking seriously, so hopefully we can concentrate a bit more on the how and why, rather than "if".
Maybe even some recipes
Tried the PPD twice now, both times lost a couple of pounds (as net loss, despite some mild regaining later). I stick to no more than 3 or 4 days though, as I find it hard to believe there's really enough protein and I'm not getting any fat-soluble vitamins etc. Besides, I now live in Malaysia and this place is very into the whole eating out with the family thing. Others seem happy going 2 weeks so why not?
Sakura, water loss is a classic issue with low carb and/or low salt, whereas most people on spuds are not only on high carb by definition but also tend to be a little generous with the salt. Especially by the 3rd day...
Going back to normal eating is probably why most of us find we lose another lb or so after stopping.
Water weight loss = when your glycogen is being used up. Since you're using glycogen on calorie restriction -> lose water weight.
