Geeking out on Low Carb
From (Am J Physiol Heart Circ Physiol 304: H1060–H1076, 2013. Review First published February 8, 2013; Ketone body metabolism and cardiovascular disease. David G. Cotter, Rebecca C. Schugar, and Peter A. Crawford): Ketone body oxidation becomes a significant contributor to overall energy metabolism within extrahepatic tissues in numerous physiological states, including the neonatal period, starvation, … Continue reading “Ketosis Information”
Noticed this morning that my body was out of ketosis. My detection method is the metallic taste in my mouth when I am in ketosis. Now, 2 hours later I am back in Ketosis. My pump delivers .5 U/hr between 4 AM and 12 PM. The rest of the time I am pumping .25 U/hr. … Continue reading “Ketosis and Insulin Levels – Status 2016-08-14”
Freeing up fat is the goal of any diet. If your body has burned enough of the fat that you have eaten and it has freed up the easily accessed stores (the fridge in Dr Fung’s analogy) then it starts burning the fat from your cells. This is called ketosis. From the WebMD site (What … Continue reading “Am I in fat burning (ketosis)? (From Aug 2016)”
Here is a nice paper from 2009 on mice fed an ad libitum ketogenic diet (Kennedy AR, Pissios P, Otu H, Roberson R, Xue B, Asakura K, Furukawa N, Marino FE, Liu FF, Kahn BB, Libermann TA, Maratos-Flier E. A high-fat, ketogenic diet induces a unique metabolic state in mice. Am J Physiol Endocrinol Metab. 2007 … Continue reading “Mice on an Ad Lib Keto Diet”
Here is another cross-over study showing the advantage of the keto diet over a medium carbohydrate diet (Johnstone AM, Horgan GW, Murison SD, Bremner DM, Lobley GE. Effects of a high-protein ketogenic diet on hunger, appetite, and weight loss in obese men feeding ad libitum. Am J Clin Nutr. 2008 Jan;87(1):44-55.). Ad libitum energy intakes were … Continue reading “Keto for the Win – Again”
Someone in a Fakebook group posted that keto is: eating in such a way that about 80% of your calories in come from healthy fats, about 15% from protein and 5% or less from carbs My median actual maintenance macros for the past 3 months (Maintenance Macros – 2018-07-20) were: Protein: 181g Carbs: 28.52g Fat: … Continue reading “Am I Keto or Low Carb?”
Contrary to much of the marketing hype, exogenous ketones inhibit fat loss. Ketones generated from the person have the following characteristics (Brianna J. Stubbs, Pete J. Cox, Rhys D. Evans, Peter Santer, Jack J. Miller, Olivia K. Faull, Snapper Magor-Elliott, Satoshi Hiyama,3 Matthew Stirling, and Kieran Clarke. On the Metabolism of Exogenous Ketones in Humans. … Continue reading “Exogenous Ketones Inhibit Fat Loss”
An interesting small study which fed subjects a very low fat diet and reversed their Type 2 Diabetes in a couple of months (Kitt Falk Petersen, Sylvie Dufour, Douglas Befroy, Michael Lehrke, Rosa E. Hendler, Gerald I. Shulman. Reversal of Nonalcoholic Hepatic Steatosis, Hepatic Insulin Resistance, and Hyperglycemia by Moderate Weight Reduction in Patients With … Continue reading “Type 2 Diabetes Cured in Less Than Two Months”
There is a correlation between level of acetone measured in the breath and fat loss. More from the study (Joseph C. Anderson. Measuring breath acetone for monitoring fat loss: Review. Obesity (Silver Spring). 2015 Dec; 23(12): 2327–2334.) notes in one study that: 1 lb/week of fat loss corresponded to BrAce = 67 nM (1.7 ppm). Every ∼40% increase in BrAce … Continue reading “Breath Ketones – Ketonix”
Earlier I found my maintenance macros. I ate to the macros today and did OK I think. My targets are listed there (minimum targets). I didn’t get in quite enough protein and I got in a bit more fat. I did CrossFit earlier today and enough yard work that my watch detected it but I … Continue reading “Day 1 of New Maintenance Numbers”
