The Need For a Competent Agent When Sell Your House Amarillo Fast

Once you finally decide to put your house for sale in the market there are few things that you have to know about the process of selling your home in the Amarillo real estate. Every buyer does inspection for whatever they purchase. And you do not have the control over the time when these buyers want to check your home. They usually visit at any time of the day, particularly at night and on weekends even at times that you do not feel entertaining strangers. If you want to sell your home quickly, you should always eager to entertain those prospective buyers and show eagerness of entertaining them. You should avoid instances of time that you do not allow showing your home when the agent is bringing a perfect buyer to see your home that was perfectly suit them. They may not have available time to revisit your home so you must always be ready in showing your Amarillo real estate home even at the least time that you expect them to visit. With this problem you can have a lockbox, so that agents have the chance of showing your home even if you are not at home. Lockbox contains your sets of keys in your home and is accessible by those Licensed Real estate Agents only. It is always an advantage on your part to hire a real estate agent. This is to remove emotional attachment from the transactions. Agents will surely represent you to every negotiation that may happen. After all of your blood, sweat and tears that you have just to have your own home, of course you do not want to hear any negative comments from any buyers. As we all know that it is hard to invest home in Amarillo real estate because homes are very expensive. It will be an insult on your part hearing buyers offering you low cost or unexpected offer. With this your agents will speak on your part and see to it to come up with one agreed price. Once your house in Amarillo real estate is "under contract" there are still a lot of behind the scene work that you have to finish. Of course you will feel relax because you have an expert real estate agent that will take care of the task for you. There are lots of procedures that you need to undergo through in “we buy houses Amarillo” , this is why it will be beneficial to hire a real estate agent.

STRESSFULL

I thought I couldn't get more stressed than when Rex got cancer and died, but I was wrong. It is a different stress, but I feel more stressed. When he was sick and getting sicker, I had one thing to think of, taking care of him and making him comfortable.During that time I was in a tunnel, trying to stay between the lines. Now I have had the house to sell, which the 2nd contract was accepted, waiting to close hopefully at end of month!!! Met the wonderful people who are buying it and I feel good about it. But still very hard emotionally dealing with it. I have had alot of business things to deal with, get rid of stuff, sell stuff, pack and pack and find place to live in Utah!!!!. Had a last pool Memorial Day party here. So many wonderful friends and family here. I had to come in the house many times so no one could see me crying. Last year we had a party and celebrated Rex's birthday at same time. So it was first Memorial Day and Rex's birthday. Hard day!!! So check list has been “sell house Amarillo”, check, sell Rex's truck, check, find place to live in SLC, check. Sell Rex's lawn mower, check, sell couches, check, sell BBQ, check. Tomorrow is my last day at work, check!! So many memories with my sweet husband going out the door. I have to keep saying it is only a house, it is only things. I have his memories and his love to hold on to right? So many memories with my friends. I refuse to say good bye, only see you later. Now it is pack, pack, throw away, donate, pack, wrap, pack!!! Will it all fit?????? Talisa and McCoy and Blake's mom Lisa came out on May 30th to help pack. So thankful for Lisa, she was like a bull dog packing. So grateful for my sweet daughter. Got so much done, I'm so grateful . McCoy is so busy, but is in the stage he wants to have his momma in sight all the time!!!! So hard to get things done.

Why Do We Eat? A Neurobiological Perspective. Part III

In the first post, I explained that all voluntary actions are driven by a central action selection system in the midbrain (the reward system).  This is the part of you that makes the decision to act, or not to act.  This system determines your overall motivation to obtain food, based on a variety of internal and external factors, for example hunger, the effort required to obtain food, and the sensory qualities of food/drink.  These factors are recognized and processed by a number of specialized 'modules' in the brain, and forwarded to the reward system where the decision to eat, or not to eat, is made.  Researchers divide food intake into two categories: 1) eating from a true energy need by the body (homeostatic eating), e.g. hunger, and 2) eating for other reasons (non-homeostatic eating), e.g. eating for social reasons or because the food tastes really good.

In the second post of the series, we explored how the brain regulates food intake on a meal-to meal basis based on feedback from the digestive system, and how food properties can influence this process.  The integrated gut-brain system that accomplishes this can be called the satiety system.

In this post, we'll explore the energy homeostasis system, which regulates energy balance (energy in vs. energy out) and body fatness on a long term basis.

An Encouraging Trend

I was in the Seattle/Tacoma airport today, and I noticed quite a few people taking the stairs even though they're flanked by escalators.  It's been my impression lately that more people are using stairs than even five years ago.  I used to be the only weirdo on the stairs, but today I shared them with about ten other people.  I know Seattle isn't necessarily representative of the nation as a whole, but I (optimistically) think of it as the vanguard in this respect.

One of the healthiest things a person can do is build exercise into daily life.  You don't have to be Usain Bolt or Lance Armstrong to reap the benefits of exercise.  In fact, evidence is acctmulating that moderate exercise is healthier than extreme exercise.  Taking the stairs instead of the elevator/escalator, walking or jogging even a modest amount, or standing for part of the day, can have an immediate, measurable impact on metabolic health (1).

Maybe it's macho, but I'll feel defeated the day I need a giant energy-guzzling machine to take me up a 15 foot incline.  I have legs, and I intend to use them.  Escalators are good for people who are disabled or have very heavy bags, but the rest of us have an opportunity to use our bodies in a natural and healthy way.  Part of the problem is how buildings are designed.  Humans tend to take the path of least resistance, and if the first thing we come across is an elevator, and the stairs are grimy and tucked away down some side hallway, we'll tend to take the elevator.  Architects in some places are building in more prominent stairways to encourage gentle exercise throughout the day.

Food Reward Friday

This week's lucky winner... the Hardee's MONSTER THICKBURGER!



Two 1/3 lb beef patties, four strips of bacon, three slices of American "cheese", mayo and bun.  This bad boy boasts 1,300 calories, 830 from fat, 188 from carbohydrate and 228 from protein.  Charred and fried processed meat, fake cheese, refined soybean oil mayo, and a white flour bun. You might as well just inject it directly into your carotid artery.  Add a large fries and a medium coke, and you're at 2,110 calories.  Who's hungry?  Actually I am.

Food Reward Fridays

Each Friday, I'm going to post a picture of a modern food so ridiculous it makes you want to laugh and cry at the same time.  I'm doing this for two reasons:
  1. To raise awareness about the unhealthy, fattening foods that are taking over global food culture.  These are highly rewarding, highly palatable, energy-dense foods that drive people to eat in the absence of hunger, and continue eating beyond calorie needs.  In many cases, the foods have been specifically designed to maximize "craveability" and palatability.
  2. Because it's funny.
Without further ado... the first lucky winner:

Candy at the Cash Register

Last week, the New England Journal of Medicine published an interesting editorial titled "Candy at the Cash Register-- a Risk Factor for Obesity and Chronic Disease."  This fits in well with our discussion of non-homeostatic eating, or eating in the absence of calorie need.

There are a few quotes in this article that I find really perceptive.

Why Do We Eat? A Neurobiological Perspective. Part II

In the last post, I explained that eating behavior is determined by a variety of factors, including hunger and a number of others that I'll gradually explore as we make our way through the series.  These factors are recognized by specialized brain 'modules' and forwarded to a central action selection system in the midbrain (the reward system), which determines if they are collectively sufficient cause for action.  If so, they're forwarded to brain systems that directly drive the physical movements involved in seeking and consuming food (motor systems).

The term 'homeostasis' is important in biology.  Homeostasis is a process that attempts to keep a particular factor within a certain stable range.  The thermostat in your house is an example of a homeostatic system.  It reacts to upward or downward changes in a manner that keeps temperature in a comfortable range.  The human body also contains a thermostat that keeps internal temperature close to 98.6 F.  Many things are homeostatically regulated by the body, and one of them is energy status (how much energy the body has available for use).  Homeostasis of large-scale processes in the body is typically regulated by the brain.

We can divide the factors that determine feeding behavior into two categories, homeostatic and non-homeostatic.  Homeostatic eating is when food intake is driven by a true energy need, as perceived by the brain.  For the most part, this is eating in response to hunger.  Non-homeostatic eating is when food intake is driven by factors other than energy need, such as palatability, habitual meal time, and food cues (e.g. you just walked by a vending machine full of Flamin' Hot Cheetos).

We can divide energy homeostasis into two sub-categories: 1) the system that regulates short-term, meal-to-meal calorie intake, and 2) the system that regulates fat mass, the long-term energy reserve of the human body.  In this post, I'll give an overview of the process that regulates energy homeostasis on a short-term, meal-to-meal basis.

The Satiety System (Short-Term Energy Homeostasis)


The stomach of an adult human has a capacity of 2-4 liters.  In practice, people rarely eat that volume of food.  In fact, most of us feel completely stuffed long before we've reached full stomach capacity.  Why?

Photos and More Gardening

I've needed new professional and blog photos for a long time.  My friend Adam Roe was in town recently, and he happens to be professional photographer, so he graciously offered to snap a few shots.  Despite less than ideal conditions, he did an outstanding job.  Here's a larger version of the photo on my profile (which Blogger shrinks down to a tiny thumbnail):

Why Do We Eat? A Neurobiological Perspective. Part I

As with all voluntary movements, eating food is an expression of activity in the brain.  The brain integrates various inputs from around the body, and outside the body, and decides whether or not to execute the goal-directed behaviors of food seeking and consumption.  Research has uncovered a lot about how this process works, and in this series I'll give a simplified overview of what scientists have learned about how, and why, the brain decides to eat.

More Thoughts on Macronutrient Trends

I had a brief positive exchange with Gary Taubes about the NuSI post.  He reminded me that there's an artifact (measurement error) in the USDA data on fat consumption in the year 2000 when they changed assessment methods.  Here are the USDA data on macronutrient consumption since 1970, corrected for loss (28.8%) but not corrected for the artifact:

Calories and Carbohydrate: a Natural Experiment

In the lab, we work hard to design experiments that help us understand the natural world.  But sometimes, nature sets up experiments for us, and all we have to do is collect the data.  These are called "natural experiments", and they have led to profound insights in every field of science.  For example, Alzheimer's disease is usually not considered a genetic disorder.  However, researchers have identified rare cases where AD is inherited in a simple genetic manner.  By identifying the genes involved, and what they do, we were able to increase our understanding of the molecular mechanisms of the disease.

The natural experiment I'll be discussing today began in 1989 with the onset of a major economic crisis in Cuba. This coincided with the loss of the Soviet Union as a trading partner, resulting in a massive economic collapse over the next six years, which gradually recovered by 2000.

A Late Summer Harvest

It's been a good year for gardening in Seattle, at least in my garden.  Thanks to great new tools* and Steve Solomon's recipe for homemade fertilizer, my house has been swimming in home-grown vegetables all summer.  I'm fortunate that a friend lets me garden a 300 square foot plot behind her house.  Here's a photo of part of today's harvest; various kale/collards, zucchini, tomatoes and the last of the pole beans:

Does Calorie Restriction Extend Lifespan in Mammals?

Until about two years ago, the story went something like this: calorie restriction extends lifespan in yeast, worms, flies, and rodents.  Lifespan extension by calorie restriction appears to be biologically universal, therefore it's probably only a matter of time until it's demonstrated in humans as well.  More than 20 years ago, independent teams of researchers set out to demonstrate the phenomenon in macaque monkeys, a primate model closer to humans than any lifespan model previously tested.

Recent findings have caused me to seriously question this narrative.  One of the first challenges was the finding that genetically wild mice (as opposed to inbred laboratory strains) do not live longer when their calorie intake is restricted, despite showing hormonal changes associated with longevity in other strains, although the restricted animals do develop less cancer (1).  One of the biggest blows came in 2009, when researchers published the results of a study that analyzed the effect of calorie restriction on lifespan in 41 different strains of mice, both male and female (2).  They found that calorie restriction extends lifespan in a subset of strains, but actually shortens lifespan in an even larger subset.  Below is a graph of the effect of calorie restriction on lifespan in the 41 strains.  Positive numbers indicate that calorie restriction extended life, while negative numbers indicate that it shortened life:

AHS11 Talk Posted

After a one-year delay, my talk from the 2011 Ancestral Health Symposium is online with slides synched.  The talk is titled "Obesity: Old Solutions for a New Problem", and it's an overview of some of the research linking food reward to food intake and body fatness.  This is the talk that introduced a fundamentally new idea to the ancestral community: not only does the chemical composition of food matter, but also its sensory qualities-- in fact, the sensory qualities of food are among the primary determinants of food intake.  I didn't come up with the idea of course, I simply translated the research for a more general audience and put my own evolutionary spin on it.

The talk would be a bit different if I were to give it today, as my understanding of the subject has expanded, and my speaking skills have improved.  However, the central message remains as true today as it was a year ago.  You can find the talk here.

The slide synching was done by an extremely generous man named Ben Fury.  As you can see in the video, he did an excellent job.  Without Ben, this video would have remained in internet limbo forever.

Below, I've published a message from Ben explaining the interesting work that he does.  Please contact him if you think it's interesting.

A Message from Ben Fury

I was writing a book on health, fitness and diet in 2009 when my house burned down in the Station Fire, along with 165,000 acres of my beloved Angeles National Forest. Since then, I've had a series of people needing help come through my life, that have upgraded and morphed my talents...

Seniors with chronic pain, falls, brittle bones, and stiff shrunken muscles.
Diabetics with out of control blood sugars, going blind, and having limbs lopped off.
Neurologically challenged people with spastic limbs and foggy brains.
Fat, listless, unhappy people with no idea how they got that way, seeing no way out of the darkness.
Each of them needing help in different ways, but all with an underlying theme of what works to help heal our conditions:
  •     Remove flour, sugar, beans, and heavily processed oils from our diet. Eat real food.
  •     Get strong.
  •     Get flexible.
  •     Stop ceding health responsibility to outside forces, and take charge of our own wellness.
  •     Only use truly evidence based medicine. Don't just pop the latest pill or get the latest surgery all the other people are doing. Be wary of the disease mongers in both the conventional and alternative camps.
  •     Find our "happy thoughts." Use the simple restoratives of sleep, play, and reflection, to let go of pain, find inner peace, and let in joy and purposeful outer direction.
The methods to accomplish these goals are varied, and I have both non-profit and for-profit ventures to share them.
Their websites are currently in development.
The for-profit is BenFury.com
The non-profit is PainRelieversUSA.org , whose mission statement is:

To move beyond pain management...
and learn to live pain free.

Ancestral Health Symposium 2012

I recently returned from AHS12 and a little side trip to visit family.  The conference was hosted at Harvard University through the Harvard Food Law Society.  Many thanks to all the organizers who made it happen.  By and large, it went smoothly.

The science as expected ranged from outstanding to mediocre, but I was really encouraged by the presence and enthusiastic participation of a number of quality researchers and clinicians. The basic concept of ancestral health is something almost anyone can get behind: many of our modern health problems are due to a mismatch between the modern environment and what our bodies "expect".  The basic idea is really just common sense, but of course the devil is in the details when you start trying to figure out what exactly our bodies expect, and how best to give it to them.  I think our perspective as a community is moving in the right direction.

Lorcaserin: the Latest FDA-approved Obesity Drug

The FDA recently approved a new drug called lorcaserin (brand name Belviq) for the treatment of obesity.  Lorcaserin causes an average of 13 lbs (5.8 kg) of weight loss over a year, compared to 5 lbs (2.2 kg) for placebo (1), which is less than the other recently approved drug Qsymia (formerly Qnexa; topiramate/phentermine).

Learning about obesity drugs is always a good opportunity to gain insight into the mechanisms that underlie the development and reversal of obesity.  If you've been following this blog for a while, you already have a pretty good guess what organ this new drug acts on.  Make your guess and read on!

Two Great Quotes About Obesity (technical)

By Dr. Hans-Rudolf Berthoud, from a recent paper, "The Neurobiology of Food Intake in an Obesogenic Environment" (1).  I came across it because it cites my review paper (2).  My perspective on obesity is similar to his.  From the abstract:
The modern lifestyle with its drastic changes in the way we eat and move puts pressure on the homoeostatic system responsible for the regulation of body weight, which has led to an increase in overweight and obesity. The power of food cues targeting susceptible emotions and cognitive brain functions, particularly of children and adolescents, is increasingly exploited by modern neuromarketing tools. Increased intake of energy-dense foods high in fat and sugar is not only adding more energy, but may also corrupt neural functions of brain systems involved in nutrient sensing as well as in hedonic, motivational and cognitive processing.
And a nice one from the conclusions:

How Should Science be Done?

Lately I keep running into the idea that the proper way to do science is to continually strive to disprove a hypothesis, rather than support it*.  According to these writers, this is what scientists are supposed to aspire to, but I've never actually heard a scientist say this.  The latest example was recently published in the Wall Street Journal (1).  This evokes an image of the Super Scientist, one who is so skeptical that he never believes his own ideas and is constantly trying to tear them down.  I'm no philosopher of science, but this idea never sat well with me, and it's contrary to how science is practiced.

New Review Paper by Yours Truly: High-Fat Dairy, Obesity, Metabolic Health and Cardiovascular Disease

My colleagues Drs. Mario Kratz, Ton Baars, and I just published a paper in the European Journal of Nutrition titled "The Relationship Between High-Fat Dairy Consumption and Obesity, Cardiovascular, and Metabolic Disease".  Mario is a nutrition researcher at the Fred Hutchinson Cancer Research Center here in Seattle, and friend of mine.  He's doing some very interesting research on nutrition and health (with an interest in ancestral diets), and I'm confident that we'll be getting some major insights from his research group in the near future.  Mario specializes in tightly controlled human feeding trials.  Ton is an agricultural scientist at the University of Kassel in Germany, who specializes in the effect of animal husbandry practices (e.g., grass vs. grain feeding) on the nutritional composition of dairy.  None of us have any connection to the dairy industry or any other conflicts of interest.

The paper is organized into three sections:
  1. A comprehensive review of the observational studies that have examined the relationship between high-fat dairy and/or dairy fat consumption and obesity, metabolic health, diabetes, and cardiovascular disease.
  2. A discussion of the possible mechanisms that could underlie the observational findings.
  3. Differences between pasture-fed and conventional dairy, and the potential health implications of these differences.

What Causes Type 2 Diabetes, and How Can it be Prevented?

In the comments of the last post, we've been discussing the relationship between body fatness and diabetes risk.  I think this is really worth understanding, because type 2 diabetes is one of the few lifestyle disorders where 1) the basic causes are fairly well understood, and 2) we have effective diet/lifestyle prevention strategies that have been clearly supported by multiple controlled trials.

Why Did Energy Expenditure Differ Between Diets in the Recent Study by Dr. Ludwig's Group?

As discussed in the previous post, a recent study by Dr. David Ludwig's group suggested that during weight maintenance following fat loss, eating a very low carbohydrate (VLC) diet led to a higher metabolic rate (energy expenditure) than eating a low-fat (LF) diet, with a low glycemic index (LGI) diet falling in between the two (1).  The VLC diet was 30 percent protein, while the other two were 20 percent.  It's important to note that these were three dietary patterns that differed in many ways, and contrary to claims that are being made in the popular media, the study was not designed to isolate the specific influence of protein, carbohydrate or fat on energy expenditure in this context. 

Not only did the VLC diet lead to a higher total energy expenditure than the LF and LGI diets, the most remarkable finding is that it led to a higher resting energy expenditure.  Basically, people on the VLC diet woke up in the morning burning more energy than people on the LGI diet, and people on the LGI diet woke up burning more than people on the LF diet.  The VLC dieters burned 326 more calories than the LF dieters, and 200 more than the LGI dieters.

It's always tempting to view each new study in isolation, without considering the numerous studies that came before it, but in this case it's essential to see this study through a skeptical lens that places it into the proper scientific context.  Previous studies have suggested that:
  1. The carbohydrate:fat ratio of the diet has little or no detectable impact on energy expenditure in people who are not trying to lose weight (2, 3).
  2. The carbohydrate:fat ratio of the diet has little or no detectable impact on energy expenditure in people who are being experimentally overfed, and if anything carbohydrate increases energy expenditure more than fat (4, 5).
  3. The carbohydrate:fat ratio of the diet has little or no detectable impact on energy expenditure during weight loss (6, 7, 8), and does not influence the rate of fat loss when calories are precisely controlled. 
This new study does not erase or invalidate any of these previous findings.  It fills a knowledge gap about the effect of diet composition on energy expenditure specifically in people who have lost weight and are trying to maintain the reduced weight.

With that, let's see what could have accounted for the differences observed in Dr. Ludwig's study.

New Study: Is a Calorie a Calorie?

A new study in JAMA led by Dr. Cara B. Ebbeling and colleagues purports to challenge the idea that all calories are equally fattening (1).  Let's have a look.  When thinking about the role of calorie intake in body fatness, there are basically three camps:

1.    Calories don’t matter at all, only diet composition matters.
2.    Calories are the only thing that matters, and diet composition is irrelevant.
3.    Calories matter, but diet composition may also play a role.

The first one is an odd position that is not very well populated.  The second one has a lot of adherents in the research world, and there’s enough evidence to make a good case for it.  It’s represented by the phrase ‘a calorie is a calorie’, i.e. all calories are equally fattening.  #1 and #2 are both extreme positions, and as such they get a lot of attention.  But the third group, although less vocal, may be closest to the truth.

What Puts Fat Into Fat Cells, and What Takes it Out?

Body fatness at its most basic level is determined by the rate of fat going into vs. out of fat cells. This in/out cycle occurs regardless of conditions outside the cell, but the balance between in and out is influenced by a variety of external factors.  One of the arguments that has been made in the popular media about obesity goes something like this:  


A number of factors can promote the release of fat from fat cells, including:
Epinephrine, norepinephrine, adrenocorticotropic hormone (ACTH), glucagon, thyroid-stimulating hormone, melanocyte-stimulating hormone, vasopressin, and growth hormone
 But only two promote fat storage:
Insulin, and acylation-stimulating protein (ASP)*
Therefore if we want to understand body fat accumulation, we should focus on the latter category, because that's what puts fat inside fat cells.  Simple, right?

Can you spot the logical error in this argument?
