My guess is that you maybe start the day highly motivated to lose weight and perhaps under eat a little bit early in the day? Then when late afternoon rolls around you’re hungry and have difficulty regulating how much you eat. The human body is a clever thing...it wants and demands what it needs. If you don’t eat enough…

People think this because we all observe that there isn’t a perfect correlation between body size/weight and fitness level. We all know heavier fit people and unfit/unhealthy skinny people. Not that there isn’t a correlation, it’s just not a perfect one. I have a BMI of 28 and play a competitive aerobic sport (medals at…

I’m a similar height/weight and I have found the exact same thing. Too few calories/heavy exercise = agonizingly slow weight loss. Slightly higher calories/heavy exercise = steady weight loss of about 1 pound/week. Too few calories and my resting heart rate drops to 48 (I’m not that fit!), I’m constipated and tired. At…

And please remember that if you have serious symptoms again like chest pain and weakness that you should head back to the ER. Even though you know the cause, arrhythmias can cause some very serious problems. Hopefully you get some answers from your cardiologist appointment tomorrow.

Yup...the body does some interesting things at times. Don’t worry....with consistency the weight will come off. My only piece of advice is to not panic and respond with further calorie restriction at this point (since it’s only been a week and it sounds like you’re already eating below the recommended most days), and to…

I don’t think you’re lacking motivation. You sound like you really want to lose weight. Sounds like you maybe need to take a look at the strategies and tools you’re using. Personally, willpower and motivation get me to about 4 pm, then I’m hungry, there’s nothing to eat in the fridge....and so it begins. So get the scale…

For some reason the title of the post really struck me. On September 1st do I want to be down 25 pounds? Hell yeah! Is it possible? Absolutely. So let’s do it.

But that’s exactly what I’m doing and what I’m suggesting others do (at least the peer reviewed stuff). I am confused by this comment. My intent in posting has only been to try and introduce some of the basic science into the discussion. Mea culpa if that’s a problem on a debate forum. My mind is not made up on the issue,…

They’re probably fine. I just prefer to go right to the peer reviewed research sources, rather than relying on someone else’s summary of it. If it’s a peer reviewed journal review I’m fine with that. I’m just cautious about non-peer reviewed blog and website articles, regardless of the authors credentials.There are lots of…

Thanks, but I’ll stick with the peer reviewed literature. Since it’s what I actually do for a living I find it easier to navigate, and more thorough, than the MFP summaries.

Well, it’s been described in the literature, so it’s clearly physiologically possible. That’s not up for debate. I haven’t seen any research that tries to estimate how common it is. Individual physiologic and endocrine adaptation to an energy deficit will presumably follow a normal distribution curve, like most things in…

Here’s an excellent review article on factors that explain variance in weight loss and adaptation to weight loss. http://www.mdpi.com/2072-6643/9/5/468/pdf#page15

This is my second time on MFP. I lost about 30 pounds in 2013 over 7 months. About a pound/week, initially at 1200 cal/day, while simultaneously training for an international Masters tournament. My resting heart rate dropped to 48 bpm (and I was NOT that fit), I was constantly constipated despite a diet that was probably…

Sadly, our bodies fight to regain the lost weight, and some people have bodies that fight harder. I’m not sure how much total weight you’ve lost, but significant weight loss can result in sustained decreases in leptin levels, which means you’ll be hungrier than you were before dieting. Unfair, but a reality for many. And…

Myfitnesspal often over estimates the calories burned in exercise, but it sounds like you’re saying you’re not losing with a 1000 to 1500 calorie deficit/day. Hard to believe that’s all measurement errors...but it’s definitely possible. So start by measuring more accurately, but I’d also have a closer look at your…

i do

I did not know it was 0.0099%. Do you have a source for that figure?

The article makes no claim for generalizability. In the context of a larger study it discusses a woman whose metabolic adaptation to energy restriction exceeded the energy deficit, resulting in weight gain on a lower calorie diet. I think they’re clear that they are reporting on one end of the spectrum of inter-individual…

I think you might need to reread the article.

Sure it has. It’s not common. It’s probably quite rare. But possible? Yes. Documented? Yes. What’s even cooler is that they’re beginning to understand the genetic basis for this response to energy restriction. See Table 2 for Patient data. https://www.tandfonline.com/doi/pdf/10.2217/17460875.2.6.651?needAccess=true…

Sure it has. It’s not common. It’s probably quite rare. Has it been reported? Yes. See Table 2 for Patient details. Truth is there is significant inter-individual variation in the extent of adaptive thermogenesis relative to the energy deficit. https://www.tandfonline.com/doi/pdf/10.2217/17460875.2.6.651?needAccess=true

“The factors that you're worrying about with "metabolism"? No. Metabolism isn't really a thing, it's a sum of things. Your basal metabolic rate is the amount of calories used by all of the various metabolic processes in your body. The greater factor for most people and what you should be focusing on is your TDEE, or total…

I think what the research shows is that significant weight loss results in long lasting changes in BMR/TDEE, so there’s no need for her to return to her previous level of eating in order to regain weight. She may regain weight at a caloric intake that would result in weight loss for most individuals without a history of…

Weigh, measure, log everything. Don’t restrict at breakfast or lunch. You’ll just eat those “saved” calories and more in the evening. Resist the urge to start your diet with a fast or ultra low calorie induction phase. Slow and steady is the way to go if you’re looking for long term results. Start your diet with a scale on…

Everyone agrees (or should) that you can only lose weight if you achieve an energy deficit. Anything else is literally impossible. No argument there. My objection is to those who reflexively respond with comments like “you’re eating more than you think you are” in response to requests for help from individuals who are…

I’m not sure this study says what you think it says. This is a National Weight Control Registry study. To be enrolled in the study you have to have lost at least 30 pounds and kept it off for at least one year. Among THOSE specific individuals there is not a significant RMR difference. That’s why they’re in the study, and…

Sorry, I don’t know how to link threads but 2 recent ones are: - Endless Plateau - overall almost 6 months now - Am I eating enough? Unfortunately there are many similar threads

Of course you only lose weight if you have an energy deficit. There is no other way. My point is that the reflexive responses to tighten up weighing and measuring, and cut calories further, is unhelpful, because there are multiple factors involved in both CI and CO. A large person on 1200 cal may not be losing weight…

The point I was trying to make is that there are numerous variables that would affect how quickly people lose weight. People seem to misinterpret CICO as meaning everyone will lose weight at a similar rate if they restrict to a similar level, but of course they don’t. That’s why the insistence of some that slower weight…

Yes, exactly.
