Accuracy of Calculated Metabolic Rate in Athletes: Best and Worst Equations are +3% to -17% Off Measured RMR | Plus: Spreadsheet to Calculate Your RMR With Each Equation

Image
Wouldn't it be cool if you could simply plug your computer into a USB-slot at the back of your head to read out your energy status...? Ah, no, it wouldn't! It's already scary enough how much Fitbit, Garmin, and co know about us. This is by no means the only problem with metabolic research, these days, but it's one that's really getting on my (and probably also your) nerves. It's all about the sick and obese. It is thus no wonder that you will easily find papers that assess how the Nelson, Mifflin, Harris-Benedict and other equations that are commonly used are off wrt the real energy requirements of the average obese type II diabetic. What you'll be hard-pressed to find, though, is data on their accuracy in athletes. I have addressed this issue before, but with the publication of a recent paper in the  Journal of Strength and Conditioning Research  there's now more data available than from all the previous studies I've seen. The effect of lean...

High(er) Dose Fish Oil (3g EPA+DHA per Day), an Effective Thermogenic for Older Women - 187 kcal/Day Higher RMR

Image
This study is different from the average "fish oil is good for you" study and that's both refreshing and revealing. Speaking of "fresh" you got a 50/50 chance you buy fresh, not rancid fish oil. I am not exactly a fan of fish oil supplementation, but I am neither ignoring the few gems among the bazillion of "fish oil is good for you" papers. Samantha L. Logan's and Lawrence L. Spriet's latest paper in the open access journal PLOS|ONE  looks as if it was one of those gems. A gem that suggests that 3g of DHA + EPA per day (2 g/d EPA, 1 g/d DHA, to be precise) will not just lower the triglyceride levels of community dwelling older, healthy women by 29%, but also (a) increase their lean mass by 4%, (b) boost their functional capacity by 7% and (c) bump up their resting metabolic rate by 14%, their energy expenditure during exercise by 10%, and the rate of fat oxidation during rest and low-intensity cycling by 19% and 27%, respectively. You...

Metabolic Damage, Energy Intake & the Human "Energy Thermostat" - An Update Based on Recent Studies

Image
You may argue that it is unfair, but there's no way to negate that people who have been sign. overweight once are at a high risk of ending up with a reduced metabolic rate when they've achieved the same weight and body comp. as people who have never been obese. You will probably have heard of, maybe even experienced the nasty reduction in basal energy expenditure that occurs during and often persists after energy restricted diets. In today's SuppVersity article, I will briefly summarize the results of a couple of recent studies that may yield new insights into a phenomenon some people call "metabolic damage". Now, "metabolic damage", or as I prefer to call it, the diet-induced (semi-)permanent down-regulation of our basal energy expenditure wouldn't be a problem if our appetite would decrease to the same degree. Unfortunately, there's a disconnect between appetite and energy expenditure of which a recent study from the University of Leeds ...

Metabolic Damage in Biggest Losers: Will Diet & Intense Exercise Make You Fat, While Surgery Will Make You Lean? Plus: How to Avoid / Correct Diet-Induced REE Reductions

Image
If you start to work out when you are already obese, it'll still help you lose weight, but if you'd been active the years before chances are you'd not have such weighty problems and wouldn't have to fear metabolic slow down. Let me answer the question in the headline of today's SuppVersity Article right away, 'cause the answer short and easy: "No!" If you compare the body composition of the Biggest Losers who were included in a recent study by scientists from the National Institutes of Health in Bethesda and the Pennington State Biomedical Research Center, the Vanderbilt University School of Medicine and the University of California-Los Angeles to that of their bariatric surgery patients, the "Biggest Losers" (BLC) had lower body fat and higher lean mass percentages than their peers who took the easy way out (Knuth. 2014). What is non-debatable, though, is the fact that the thirteen "Big Losers" also exhibited significantly m...

22g High EAA (6g) Protein + 36g CHO Pre- / Intra-Workout Boost Fat Oxidation & PWO Resting(!) Energy Expenditure

Image
I don't doubt that you can do that, too! It does sound awkward: If you mix Twinlab: Amino Fuel (22 g protein - 6 g essential amino acids | L-phenylalanine: 633 mg; Lvaline: 781 mg; L-tryptophan: 133 mg; L-threonine: 679 mg; L-isoleucine: 565 mg; L-methionine: 292 mg, L-histidine: 282 mg; L-leucine: 1350 mg; L-lysine: 1449 mg) with a regular  sports recovery drink that contains 36g of simple sugar, down half of the resulting 800ml serving of whatever you want to call this mix immediately before your workout and consume the rest during the rest periods between sets, this will have measurable effects on your resting energy expenditure and fat oxidation. From long-term to short time effects At first, it does questionably sound counter-intuitive that the ingestion of an EAA + carbohydrate mixture before / during would increase the resting energy expenditure and rate of fatty acid oxidation after your workout. On the other hand, if you think about the long-term effects of co...
