Written by | published on
Image
Betaine or citrulline? Choose now. Article #2 of this series is a bit more "anabolic" than the first serving . Based on the abstracts to studies by Hudson et al, Cicholski et al and Hwang et al it explores the effects of betaine supplementation on the adaptational response to resistance training in female rookies and the longitudinal effect of the NOx-boosting combination of citrulline + glutathione (see previous article ) on the body composition of resistance-trained male subjects. As usual, the discussion of the studies is infused with plenty of information from previous research... and for those who want nothing but the gist, there are the practical implications in the bottom line.

Written by | published on

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...

Fish vs. Krill Oil, SFA ↔ PUFA - False Advice, Low-FODMAP Diet for Athletes GI Tracts - Nutrition Research Update 9/17

Written by | published on
Image
In contrast to the often-asked krill vs. fish oil question, the issue of PUFA vs. SFA seems to be resolved. At least if we focus on replacing SFA with N-6-PUFA well-controlled RCTs don't show a benefit. If studies are interesting, but there's not enough to dissect for a full SuppVersity  article, they make it to the short news . Today's installment is a nutrition research update and it deals with (1) the often-asked question whether there's a health- or performance-relevant difference between fish and krill oil , (2) the often-heard advice to replace saturated fats in your diet with omega-6 fats to improve your heart health, an advice of which a new meta-analysis shows quite cleverly that it's an artefact due to the inclusion of insufficiently controlled studies, and (3) using the low-FODMAP diet in athletes to reduce gastrointestinal problems that range from burping to diarrhea.

Meta-Analysis: Dieting Reduces Food, Fat, Sugar, Starch & Junk-Food Cravings | In Whom? Why? Is it Diet Dependent?

Written by | published on
Image
Believe it or not - At least after some time, a severely energy restricted diet will reduce your cravings for donuts, pizza, pasta, and even chocolate statistically significantly - the questions from the headline do yet remain: Who benefits? What's the mechanism? And do the effects depend on your diet / its macros? If you browse blogs and read e-books, you will read highly popular claims like "Dieting is useless, it just makes you hungry. If you want to lose weight, you got to stop eating carbs and reduce insulin." Those claims are popular because they entail the (unwarranted) claim that you could lose weight without cutting back on your energy intake. WRONG! Fortunately, more and more people seem to understand that. One thing that will still be hard for them to swallow is the conclusion of the latest meta-analysis that addresses the ubiquitous claim that "calorie restriction may increase food cravings" (Kahathuduwa 2017), would thus ruin all your weight l...

Which Fats Should Mothers-to-Be Consume if They Don't Want Their Kids to be Obese as Early as With 2-7 Years?

Written by | published on

Fat is an important nutrient for the unborn child. Accordingly, the question is not if pregnant women should consume fat, it's rather how much and at which ratios saturated, monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids should be consumed. A new study does now go even one step further and tries t assess the optimal amount of individual fatty acids like arachidonic acid (ARA), Eicosapentaenoic acid (EPA) or Docosahexaenoic acid (DHA). It should be obvious: Out of ethical reasons, the question from the headline can only be answered based on rodent or epidemiological studies. Now, I am not exactly a fan of epidemiology, but  in this important case, I wouldn't like to rely on rodent data, which tends to deviate significantly from human data in long-term trials spanning several developing periods. As you will probably know, a high-intake ratio of n -6/n-3 polyunsaturated fatty acids (PUFAs) has been suggested to contribute to excess fetal adipose tis...
