Obesity and the role of adipose tissue in inflammation and metabolism



Obesity and the role of adipose tissue in inflammation and metabolism

Andrew S Greenberg and Martin S Obin

Abstract

Recent discoveries, notably of the hormones leptin and adiponectin, have revised the notion that adipocytes are simply a storage depot for body energy. Instead, adipocytes are also endocrine organs, with multiple metabolic roles in regulating whole-body physiology. Small adipocytes in lean individuals promote metabolic homeostasis; the enlarged adipocytes of obese individuals recruit macrophages and promote inflammation and the release of a range of factors that predispose toward insulin resistance. Exercise activates the AMP-activated protein kinase (AMPK) in muscle and other tissues, a pathway that increases fat oxidation and glucose transport. Importantly, the adipocyte hormones leptin and adiponectin also activate AMPK; remarkably, the same pathway is activated by certain antidiabetic agents such as thiazolidinediones. Increasingly, our understanding of the adipocyte as an endocrine organ is leading to new insights into obesity and health.

Dietary patterns in relation to quality-adjusted life years



Dietary patterns in relation to quality-adjusted life years in the EPIC-NL cohort

Heidi P. Fransen, Joline W.J. Beulens, Anne M. May, Ellen A. Struijk, Jolanda M.A. Boer, G. Ardine de Wit, N. Charlotte Onland-Moret, Yvonne T. van der Schouw, H. Bas Bueno-de-Mesquit, Jeljer Hoekstr, Petra H.M. Peeters.

Abstract

Background

Dietary patterns have been associated with the incidence or mortality of individual non-communicable diseases, but their association with disease burden has received little attention.

Objective

The aim of our study was to relate dietary patterns to health expectancy using quality-adjusted life years (QALYs) as outcome parameter.

Methods

Data from the EPIC-NL study were used, a prospective cohort study of 33,066 healthy men and women aged 20-70 years at recruitment. A lifestyle questionnaire and a validated food frequency questionnaire were administered at study entry (1993-1997). Five dietary patterns were studied three a priori patterns (the modified Mediterranean Diet Score (mMDS), the WHO-based Healthy Diet Indicator (HDI) and the Dutch Healthy Diet index (DHD-index)) and two a posteriori data-based patterns. QALYs were used as a summary health measure for healthy life expectancy, combining a person’s life expectancy with a weight reflecting loss of quality of life associated with having chronic diseases.

Results

The mean QALYs of the participants were 74.9 (standard deviation 4.4). A higher mMDS and HDI were associated with a longer life in good health. Participants who had a high mMDS score (6-9) had 0.17 [95% CI 0.05;0.30] more QALYs than participants with a low score (0-3), equivalent to a two months longer life in good health. Participants with a high HDI score also had more QALYs (0.15 [95% CI 0.03; 0.27]) than participants with a low HDI score.

Conclusion

A Mediterranean-type diet and the Healthy Diet Indicator were associated with approximately 2 months longer life in good health.

BMI calculator wrongly labelling thousands as obese, research shows, plus BMI and Spinal Cord Injuries


The BMI calculator used in the public health system to measure obesity rates is highly flawed and could be slapping a false fat label on thousands of Australians, new research has highlighted.

A study into the size and shape of women aged 18-44 has found that almost one-third of participants were miscalculated as obese using the BMI calculator alone, highlighting the need for body measurements, percentage body fat and muscle mass to be introduced into testing.

Read the rest.

Your waist measurement compares closely with your body mass index (BMI), and is often seen as a better way of checking your risk of developing a chronic disease.


Measuring the waist circumference in people with a SCI should be done in supine position.

Being overweight is a common problem for people with spinal cord injury (SCI). Some research shows that two out of three people with SCI are overweight. Excess weight gained after SCI is difficult to lose, and it is hard to maintain weight over time and avoid putting on extra pounds. In part this is due to a reduced ability to move freely. The higher the injury, the more difficult it is to move, stay active, and exercise. A person with a cervical SCI will have more difficulty moving compared to someone with SCI in the lower spine. The same is true for the completeness of an injury. A person with an incomplete injury who is able to walk will likely burn more calories than a person who has a complete injury and uses a wheelchair full time.


A review of body mass index and waist circumference as markers of obesity and coronary heart disease risk in persons with chronic spinal cord injury.


Waist circumference is the best index for obesity-related cardiovascular disease risk in individuals with spinal cord injury.

Dietary Animal and Plant Protein and Human Bone Health: A Whole Foods Approach


Image result for diet and calcium

Dietary Animal and Plant Protein and Human Bone Health: A Whole Foods Approach

Linda K. Massey

Urinary calcium excretion is strongly related to net renal acid excretion. The catabolism of dietary protein generates ammonium ion and sulfates from sulfur-containing amino acids. Bone citrate and carbonate are mobilized to neutralize these acids, so urinary calcium increases when dietary protein increases. Common plant proteins such as soy, corn, wheat and rice have similar total S per g of protein as eggs, milk and muscle from meat, poultry and fish. Therefore increasing intake of purified proteins from either animal or plant sources similarly increases urinary calcium. The effects of a protein on urinary calcium and bone metabolism are modified by other nutrients found in that protein food source.

For example, the high amount of calcium in milk compensates for urinary calcium losses generated by milk protein. Similarly, the high potassium levels of plant protein foods, such as legumes and grains, will decrease urinary calcium. The hypocalciuric effect of the high phosphate associated with the amino acids of meat at least partially offsets the hypercalciuric effect of the protein. Other food and dietary constituents such as vitamin D, isoflavones in soy, caffeine and added salt also have effects on bone health. Many of these other components are considered in the potential renal acid load of a food or diet, which predicts its effect on urinary acid and thus calcium. “Excess” dietary protein from either animal or plant proteins may be detrimental to bone health, but its effect will be modified by other nutrients in the food and total diet.

The associations between overweight, weight change and health related quality of life: Longitudinal data from the Stockholm Public Health Cohort 2002–2010

N. Döring, J. de Munter, F. Rasmussen.

Abstract

Objective

Cross-sectional studies have shown that people with obesity and overweight report lower health related quality of life (HRQoL). With a lack of longitudinal studies, this study aims to assess the association between eight-year weight change and HRQoL measured by the EQ-5D instrument and to investigate whether the association differs with regard to baseline body mass index (BMI).

Method

A population-based survey was conducted among a random sample of 31,182 individuals from Stockholm County aged 18–84 years in 2002 and reassessed in 2010 and supplemented by record linkage with regional and national registers. Multivariate Poisson regression and linear regression were conducted with adjustments for socio-demographic and health-related variables and baseline BMI category as effect modifier for the association between weight change and HRQoL.

Results

Individuals with overweight and obesity respectively have 0.014 and 0.039 lower EQ-5D indexes compared to those being normal weight. Over the eight-year follow-up, 17.6% gained moderately (≥ 5% body weight) and 13.9% gained heavily (≥ 10% body weight) in weight. In the fully adjusted analysis, heavy weight gain was associated with a significantly lower overall EQ-5D index and an increased risk of reporting impairment in all but one EQ-5D dimensions irrespective of baseline BMI category. Weight reduction had no significant preventive effect.

Conclusion

Next to obesity status itself, weight gain leads to impairment in HRQoL irrespective of BMI category at baseline while eight year weight loss seems not to have the reversed effect on HRQoL, emphasizing the importance of primary prevention of weight gain.

Are you using protein powder supplements?


"These so called 'dietary supplements' are not considered to be a food or a drug in most countries and therefore the contents and purity of these products is NOT tested or closely regulated by national governments. Clearly, the burden of safeguarding athleticism and public health against contaminated dietary supplements for building muscle in athletes has been placed on the individual." 

I recently came across some very interesting articles about the use of protein powder supplements. I suggest you read them before deciding to put them in your dietary/training program:

1. Here are the average amounts of metals we found in three servings of these protein drinks - ConsumerReport.org
3. Consumers Union, the nonprofit publisher of Consumer Reports, believes that the FDA's oversight under the Dietary Supplement Health and Education Act is inadequate to ensure that protein drinks and other dietary supplements are consistently low in steroids heavy metals and other contaminants -
ConsumerReport.org
4. Many dietary supplements are contaminated with steroid-like chemicals that cause a 'positive' doping test and that are not known to be safe - The University of Texas
5. Why Steroids Are Bad for You -  WebMD

Apart from the possible negative effects of these supplements, there is an important reason I, personally, do not use them: it is more fun and a greater challenge for me to test my limits with what I have and what my body can do and without any "external" help ;-)

PrecisionNutricion



Our continuing research drives new coaching practices that our clients benefit from every single day. And our coaching generates new research that we can apply in the future.

Diets. They've become a cliche, haven't they? We're on them, then we're off. We stick to the program, then we fall "off the wagon".

We're told that if we just found the perfect program -- and were just a little more disciplined, had just a little more willpower -- we'd finally be successful.

But that's the great lie of the fitness and nutrition industry.

Yes, it sells more diet books. And yes, it helps fitness gurus get more attention.

But it does nothing to help you figure out what works for you and how to stick to it.

Here's the truth: If you repeatedly struggle with diet programs, jumping on another diet program can't be the answer.

What you need instead is guidance. Someone who can help you figure out the few important things you should be doing differently.

Someone who can walk alongside you, troubleshooting the inevitable challenges and difficulties that come up.
That's real coaching, and that's what we do at Precision Nutrition.

Since 2000, our world-class, multidisciplinary team of counselors, doctors, exercise specialists, naturopaths, and nutritionists have coached more than 200,000 people in nearly 100 countries through our coaching and certification programs.

When working with our clients:

  • We listen to their needs and what they want to accomplish.
  • We learn how they live.
  • We discover what’s really important to them.
  • We work together to create the right nutrition and exercise approach; personal and unique, based on their goals and lifestyle.
  • And then we coach them through the process; helping with the inevitable roadblocks along the way to success.

We Can! - ways to enhance children's activity & nutrition


Boy raising arms in the air

National Heart Lung and Blood Institute Logo

A great movement of the National Heart, Lung, and Blood Institute in the USA, We Can! (Ways to Enhance Children's Activity & Nutrition) is a national movement designed to give parents, caregivers, and entire communities a way to help children 8 to 13 years old stay at a healthy weight.

Research shows that parents and caregivers are the primary influence on this age group. The We Can! national education program provides parents and caregivers with tools, fun activities, and more to help them encourage healthy eating, increased physical activity, and reduced time sitting in front of the screen (TV or computer) in their entire family.

We Can! also offers organizations, community groups, and health professionals a centralized resource to promote a healthy weight in youth through community outreach, partnership development, and media activities that can be adapted to meet the needs of diverse populations. Science-based educational programs, support materials, training opportunities, and other resources are available to support programming for youth, parents, and families in the community.

How much protein is right for you when you work out?




We all have the same question when we start working with our muscles. Here is a very nice article on this matter on By Mike Roussell on Livestrong.com.

What I point out from this is the following:


  • You need more protein during a weight-loss program, both to lose fat and to preserve your muscle
  • About 25-30 percent of your calories should come from protein in that case
  • The amino acids that form the building blocks of protein provoke a much-lower insulin response than the one triggered by a high-carb meal. So consuming more protein will have a less dramatic affect on your blood sugar.


  • Never overdo it however. Keeping your protein's level at that percentage (no more, no less) is crucial for your overall health.

    Some general principles on how many calories should you eat and a Basal Metabolic Rate (BMR) calculator you can find in this link.

    Calories are needed to provide energy so the body functions properly. The number of calories in a food depends on the amount of energy the food provides. The number of calories a person needs depends on age, height, weight, gender, and activity level. People who consume more calories than they burn off in normal daily activity or during exercise are more likely to be overweight.

    Fat: 1 gram = 9 calories 
    Protein: 1 gram = 4 calories 
    Carbohydrates: 1 gram = 4 calories


    Always ask your personal nutritionist and/or GP before you follow any guideline on your own.
