Lean Body Mass Maintenance and Metabolic Rate Slowdown – Q&A
I suspect that some of this comes down to an issue of semantics (you sort of get to part of what I’m going to talk about in your second paragraph) but some of it doesn’t. The short answer to your question is that your assumption isn’t entirely correct; even with 100% maintenance of lean body mass (LBM) there can still be some metabolic slowdown. Now here’s the longer answer.
Do I Need to Eat More Fat to Burn Fat – Q&A
I suspect that the idea that one needed to eat fat to burn fat came out of a misunderstanding of some of the early literature on low-carbohydrate/high-fat/ketogenic diets (note: I’m defining a ketogenic diet here as any diet that contains less than 100 grams of dietary carbohydrate; a topic discussed in more detail in my first book The Ketogenic Diet).
Protein Intake While Dieting – Q&A
The above question actually came through in the comments section of Exercise and Weight/Fat Loss: Part 2 and I thought it was important enough to address explicitly since it’s a place where I still see many mainstream diets and dieters making mistakes. It’s worth noting that bodybuilders and other strength athletes have been promoting higher protein intakes while dieting for decades and this is yet another place where modern science has ended up validating those beliefs many years after the fact.
Exercise and Weight and Fat Loss: Part 2
Certainly larger amounts of exercise can approach significance (and as folks become fitter, they can burn more calories with activity) but the idea that a little bit of exercise is going to have a massive impact on anything is fairly misguided. However, there are more ways that exercise might positively impact on weight/fat loss (especially when combined with changes in diet) and that’s what I want to look at today. I’d mention that readers should check out PJ Striet’s comments in Exercise and Weight/Fat Loss: Part 1 for some other potential benefits of exercise outside of weight and fat loss per se.
Exercise and Weight and Fat Loss: Part 1
I think it was last year some time that Time magazine ran an article to the effect of “Exercise will make you fit but it won’t make you thin.” Yes, it’s taken me that long to get around to writing about this. I remember someone asking me about this (it might have been my mom) and I wasn’t really sure what the issue was; I had written back in my first book The Ketogenic Diet about some of the realities of exercise and fat loss. Most of my other books have at least dealt with the issue to some degree.
Role of Nonexercise Activity Thermogenesis in Resistance to Fat Gain in Humans – Research Review
But as it turns out, that’s not all that’s going on. As I discussed in The Energy Balance Equation one mistake people often make is assuming that the output side of the equation is static; that the energy output of a given individual is invariant over time. But we’ve known for decades that this isn’t the case. In response to both increases and decreases in food intake (as well as body weight), we know that basal or resting metabolic rate (BMR/RMR) can go up and down.
