food environment :
-Residential property values predict obesity rates in women better than education or income!
-There is an 8-fold difference in obesity rates depending on the supermarket chain you shop at.; obese people shop at Albertsons or Safeway (30+%obesity) and not at Whole Foods (4% obesity)
-Proximity to supermarkets was unrelated to obesity rates. People who don’t live in food deserts drive to them to shop!

Exercise Can Produce Healthy Chatter
Between Bone, Fat And Pancreatic Cells
Cells in bone, fat and the pancreas appear to be
talking to each other and one thing they likely are saying is, « Get
moving. » Blood levels of the hormone osteocalcin, made by bone-producing
osteoblasts, might be a good indicator of how things are going in all three
areas. The idea is that bones can possibly sense environmental stimuli such as
being physically active or sedentary and dictate energy regulation accordingly
Deadly Link Between High Salt Intake And
Obesity May Be Explained By Abnormal Activation Of A Protein
high dietary salt intake and obesity work together to
trigger an abnormal activation of a cellular protein called Rac1. hen obese
« salt-sensitive » rats were fed a high-salt diet, the team found that
Rac1 activated the mineralocorticoid receptor (MR) on the rats’ kidney cells. Both
of these substances promote the reabsorption of salt, which causes the body to
retain fluid and results in high blood pressure.
Compounds that stimulate
thermogenesis in obesity management: from pharma to functional food Dulloo
-Obesity Reviews Sept
The concept of managing obesity through the
stimulation of thermogenesis is currently a focus of considerable attention by
the pharmaceutical, nutraceutical and functional food industries. Compounds or
combination of compounds with thermogenic and fat-oxidizing potentials are
those that possess both sympathomimetic stimulatory activity and acetyl-coA
carboxylase inhibitory property, and are capable of targeting both skeletal
muscle and brown adipose tissue. The thermogenic potentials of products so far
tested in humans range from marginal to modest, i.e. 2–5% above daily energy
Promising New Obesity Drug Contrave® Looks Set

Why Even Resolute Dieters Often Fail – NYTimes.com 20 Sept
If you’ve been trying for years to lose unwanted
pounds and keep them off, unrealistic goals may be the reason you’ve failed. It
turns out that a long-used rule of weight loss — reduce 3,500 calories (or burn
an extra 3,500) to lose one pound of body fat — may be incorrect and can
ultimately doom determined dieters.
Fat burners: nutrition supplements
that increase fat metabolism – Obesity Reviews 22 Sept
The term ‘fat burner’ is used to describe nutrition
supplements that are claimed to acutely increase fat metabolism or energy
expenditure, impair fat absorption, increase weight loss, increase fat
oxidation during exercise, or somehow cause long-term adaptations that promote
fat metabolism. The list of supplements that are claimed to increase or improve
fat metabolism is long; the most popular supplements include caffeine,
carnitine, green tea, conjugated linoleic acid, forskolin, chromium, kelp and
fucoxanthin. Caffeine and green tea are the only compounds that have data to
back up its fat metabolism-enhancing properties

The 5 A’s Approach To Obesity
Sharma 19 Sept
a framework for behavioural counselling known as the 5
A’s (ask, advise, assess, assist, and arrange). An adaptation of the 5 A’s for
obese patients includes assessment of patient health risk, assessment of
current behavior and readiness to change, advising the patient to change
specific behaviors, agreeing about the behaviors and collaboratively setting
goals, assisting patients in addressing barriers and securing support, and
arranging for follow-up

Healthy Eating Message: 13 Sept
Make Half Your Plate Fruits and Vegetables
Policies that promote healthy eating
could cut heart disease deaths by half, UK study finds
The study identifies six foods which make could a
significant improvement to cardiovascular disease rate. Researchers estimate
that eating more fruit, vegetables, whole grains, nuts (in place of starch),
vegetable oils (in place of animal fats) and fish and seafood in the diet it
would result in 9.2million fewer deaths globally. Likewise, limiting our intake
of salt and industrial trans fats would have a positive effect on CVD rates and
could save 2.6 million lives globally.
Obese 8- and 9-year-olds are more likely to suffer socially and
emotionally than their normal-weight peers, a new study finds.
How to Talk About Weight With Your
WebMD: 19 Sept
« Saying ‘We need to talk about your weight,’ puts
a lot of pressure on the kid. Instead, parents should talk about healthy eating
and exercise habits. But this shouldn’t be a one-time, big talk. It should be
an ongoing conversation, even if your child is not overweight.
The neurocognitive connection between
physical activity and eating behaviour
– Joseph – Obesity Reviews – 22 Sept
This impulsive eating drive may be counteracted by
physical activity due to its enhancement of neurocognitive resources for
executive functions and goal-oriented behaviour. By enhancing the resources
that facilitate ‘top-down’ inhibitory control, increased physical activity may
help compensate and suppress the hedonic drive to over-eat. Understanding how
physical activity and eating behaviours interact on a neurocognitive level may
help to maintain a healthy lifestyle in an obesogenic environment.
Canadians consume 26 teaspoons of
sugar daily: StatsCan 22 Sept
That amounts to 110 grams a day and accounts for 21.4
per cent of Canadians’ overall calorie intake. The total includes sugar that
occurs naturally in food such as milk and fruit, as well as sugar that is
added, the latter of which tends to be less nutritious. 35 per cent — of
Canadians’ sugar intake was from foods outside the categories of grains, fruits
and vegetables, meat products and milk products. This « other » food
category, which includes things such as candy and soft drinks, is where added
sugar is most likely to be found, Statistics Canada said.

Health and economic burden of the projected obesity trends in the USA and the UK : The Lancet 26 August
trends project 65 million more obese adults in the USA and 11 million more obese adults in the UK by 2030, consequently accruing an additional 6—8·5 million cases of diabetes, 5·7—7·3 million cases of heart disease and stroke, 492 000—669 000 additional cases of cancer, and 26—55 million quality-adjusted life years forgone for USA and UK combined.
The global obesity pandemic: shaped by global drivers and local environments
: The Lancet 26 August
In low-income countries, obesity mostly affects middle-aged adults (especially women) from wealthy, urban environments; whereas in high-income countries it affects both sexes and all ages, but is disproportionately greater in disadvantaged groups. Within populations, the interactions between environmental and individual factors, including genetic makeup, explain variability in body size between individuals.

Etiology – Determinants
New Link Found Between Obesity And Insulin Resistance by examining the levels of proteins in the livers
: 3 August
Scientists at Joslin Diabetes Center now have uncovered a new way in which obesity wreaks its havoc, by altering the production of proteins that affect how other proteins are spliced together. In the case of these proteins whose production drops in the livers of obese people, this process changes the function of other proteins that can cause excess fat to be made in the liver.
Mechanisms linking obesity to hypertension
– Obesity Reviews – : 15 August
Overweight and obesity are associated with adipose tissue dysfunction, characterized by enlarged hypertrophied adipocytes, increased infiltration by macrophages and marked changes in secretion of adipokines and free fatty acids. This results in chronic vascular inflammation, oxidative stress, activation of the renin-angiotensin-aldosterone system and sympathetic overdrive, eventually leading to hypertension.
Bariatric Surgery Reduces Response to Food Cues? A Sharma 8 August
patients tell you how their previous obsession and desire to eat (many liken this to a addiction) before surgery, has been replaced with a surprising disinterest, not to say, indifference to foods that they previously found most tempting and rewarding. Following surgery, there was a distinct decrease in the activation of key areas of the brain known to be involved in the mesolimbic reward pathways in response to high-caloric highly palatable food cues (pepperoni pizza, fudge sundae).
