'Training Low[Carb]' Requires 0.12g/kg Extra-Protein | Fitbit Fitness Data Decently Reliable | Plus: Salt vs. Passin' Out

Written by | published on
Image
Mixed news about nutrition, exercise, and supplementation. In the absence of game-changing nutrition, exercise, and supplementation science I decided to post one of the recently rare installments of the good old " on short notice " column at the SuppVersity . This installment of the " short news " features two plus one papers from the latest issue of "Medicine & Science in Sports & Exercise"  and their, as of yet, unpublished "ahead of print" articles. While we'll start with a short discussion of the latest investigation into the accuracy (or rather usefulness) of your (old) Fitbit Charge 2.0 , I suspect that most of you will be more interested in the "training low [carb/glycogen]" study which is the first to quantify the (to be expected) increase in protein/amino acid requirements in those who avoid carbs to maximize the mitochondrial response to exercise (see "Maximizing Training-Induced Cellular Adaptation: T...

Missed the ISSN 14th International Society of Sports Nutrition (ISSN) Conference and Expo? I've sifted through the proceedings and picked studies of for a multi-part article series. Today: IIFYM & Nutrient Deficiencies, (Iso-)Leucine & Blood Glucose and the notorious question: How much protein do lifters need? If you have, just like me, been unable to attend the "Fourteenth International Society of Sports Nutrition (ISSN) Conference and Expo" on June 22-24, 2017, you have missed the presentations of the following selection of studies I plugged from the proceedings . Studies like Michael Dahlinghaus' short-term (3 week) Paleo diet intervention over the course of which the subjects, the 11 healthy, normal-weight subjects who had been randomized to the intervention group lost 3.27lbs (P < .05), improved their systolic BP by 7.46 (P < .043) and boosted at least one of the fitness measures Dahlinghaus included, i.e. the number of push-ups they could do be...

Protein - 0.8g/kg Insufficient for Female Athletes, Too. Plus: Revised RDA is 1.71-2.2 g/kg/d Depending on Sport & Sex

Written by | published on

With average daily protein intakes of only 90±24 g (Gillen 2017), many female athletes are probably missing the sweet spot of ~1.7g/kg/d. I guess I am preaching to the choir when I write that the recommended daily allowance (the magical "RDA") for protein is laughable; the number of studies which show that an increased protein intake will have beneficial metabolic effects is increasing by the day; the subjects of these studies are men and women, kids, teens, tweens, adults, and grandparents, perfectly healthy or sick, lean or fat... and in all of these increasing the protein intake to ~2x the RDA of 0.8g/kg has been found to be associated with significant beneficial effects on body composition and/or health in the majority of the studies ( learn more ). High-protein diets are much safer than some 'experts' say, but there are things to consider...

Protein Intake & Muscle Catabolism: Fasting Gnaws on Your Muscle Tissue and Abundance Causes Wastefulness

Written by | published on

How much of the protein you can eat and how much of it you need two keep the status quo are very different questions. Don't worry, this article is not about the notorious " Anabolic Barndoor " or the purported magic of "nutrient timing" and post.workout supplements. The thing I want to discuss in today's SuppVersity article is of a more general nature and revolves around the upregulation of the ubiquinase enzymes and consequent proteolysis (=catabolims) of skeletal muscle tissue ... or if you want to use my buddy Carl Lanore's term: "The loss of metabolic currency" we all know you better avoid at all costs, if you care about aging healthily.  You can learn more about protein intake at the SuppVersity Are You Protein Wheysting? Cod protein for recovery Protein requ. of athletes High EAA protein for fat loss Fast vs. slow protein Too much ado about protein? What we are going to deal with today is protein breakdown, o...
