Is ‘Food Addiction’ a Subtype of
Obesity
?  A Sharma 14 Sept
In a paper just published in Appetite, Caroline Davis and colleagues from Toronto’s York
University provide evidence suggesting that ‘food addiction’ (FA) may be a
valid clinical sub-phenotype of obesity that may possess different
vulnerabilities to environmental risk factors.

14 Sept
 Living in an enriched environment with complex

health. In white fat, enrichment induced the upregulation of the brown fat cell
fate determining gene Prdm16, brown fat-specific markers, and genes involved in
thermogenesis and
β-adrenergic signaling.

Exercise Can Produce Healthy Chatter
Between Bone, Fat And Pancreatic Cells
22 Sept
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
 21 Sept
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.

through in-vitro fertilization (IVF). The science is not certain and some
believe a ban would be tantamount to discrimination, yet a growing number of
fertility doctors worldwide already bar treatment based on a woman’s Body Mass

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
expenditure.

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

How to Talk About Weight With Your
Child
 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.

DrSharma Obesity Notes 23
Sept
Current approaches to managing childhood obesity
recommend family-centred-care (FCC). Effective collaboration between clinicians
and parents which include a positive therapeutic relationship, negotiation of
health care delivery, and regular monitoring and evaluation, emphasizes the
importance of tailoring health services to families’ needs, respect parents as
experts, and identify clinician responsiveness as pivotal to partnerships with
families.

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.

 Behaviour

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.

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.

Weight Control while Eating in a Resort for a Week:  impossible mission?

Weight Control while Eating in a Resort for a Week: impossible mission?

Controlling your weight while eating in a resort for a week is a real challenge. This was my case last week. Here are the key points about what may help or jeopardize maintaining your weight.

Duchesnay, Lac St-Joseph

I was coordinating the Obesity Boot Camp for the sixth year in a row, with a group of 24 graduate students coming from all parts of Canada during 9 days at la Station Touristique Duchesnay QC. This is a **** resort and restaurant own and operated by the Quebec government (SEPAQ). The rooms  (with AC in the Auberge main building) are very comfortable, the view on the lake is magnificient, the access to nature is exquisite, and the food is unfortunately… delicious.

I say unfortunately because when you are a gourmand-gourmet like me, this kind of gastronomic food is very interesting for the eye, for the pallate, for the stomach and, … for the brain, the site of eating behaviour regulation and … reward.

Here are the positive points that helped me to achieve an equilibrate food intake.

The menu is composed of healthy salads, tasty soups, nice meat like veal, a choice of fish or vegetarian plate every meal. There are sufficient occasions to eat enough vegetables, but not everyday depending of your plate choice. Some « nouvelle cuisine » nice presentation plates with meat or pasta were accompaign with too few veggies. Fortunately I could catch up the next meal or the day after when it happenned.  I was also pleased with choosing fish 5 times during the week, which contributed to lower calorie intake for these meals.

Delicious Antipasto Salad

A key point was the portion control for lunch and dinner. I could not add more food in my plate or serving a second plate, since it was a choice of fixed 3 courses menu served individually at the table.

I was happy with my beverage consumption which can easily add calories on top of your daily intake without notice. This year, I decided to refuse the orange juice that was offer to everybody by the waiter for breakfast and at the break. Especially that the portion served  was too high, about 12 onces. I rather chose a glass of milk, source of proteins, calcium and vitamin D and A, and replaced the fruit juice with fresh fruits. On lunch time, I had only water, and a small glass of wine for dinner.

At the break, only a 4 oz iced tea at few occasions. Nothing else.

In my room, we had access to a fridge. I put in it and drank five bottles of diet Pepsi, half a bottle of wine and 9 beers for the whole week. Not bad at all. Reasonable, except during the karaoke night party the last day. Drank too much too late. Only once.

An other positive aspect was that this food environment gives practically no occasion to binge or to snack at night. One late evening, I had a crave for salt. Normally, I would have had a full bag of chips; 500-800 calories. The small box of Pringles available in the basket provided by the hotel was 3$, and the closest convenience store was at 5km. These economic and environmental arguments were stronger than  my crave. Ipassed and ate some strawberries and cherries I stored in the fridge before going to bed.  

We had the occasion to exercise during the free time allowed between 4:30 and 6:30 pm. I did arbre-en-arbre on Monday, kayaking one hour on Tuesday and swam in the lake 4 times, usually 3 km worth for spending 600 kcal each time, enough to afford… the dessert! My credo: Move more, eat more!

Does-it worth a portion of fruit?

There are also many negative aspects that put me at risk for overeating.

The worse challenge was to refuse the dessert served … twice a day.  All very tasty, looking attractive; the kind of triple chocolate cake you normally find in the counter of a pastry shop. I could simply not resist. Geeh! That was a running gag. I even had 2 portions at two occasions, grabbing the one my next colleague was putting aside. No way I would  returned that portion. No waste!  I could have replaced on demand the cake by a fruit salad, but did not one single time. Shame on me.

The breakfast buffet was a major challenge. Considering that breakfast is my preferate meal, it was quite difficult to be reasonable. I had to decide the quantity of food  to put in my plate. This is why I was choosing a small plate, which help to limit the portions served. However, I was also choosing a bowl of yogurt (a mix of plain or flavored) and fresh fruits. Never more than one toast, and sometimes a small piece of chocolatine. No orange juice but a glass of milk.

I was always getting enough proteins by choosing a good portion of eggs (scrambled, omelette, poached or benedictine). The omelettes were very attractive. Personnally cooked for me, I could choose to add a full bowl of vegetables and meat including small shrimps! Delicious.

The final day was the most challenging with two brunches! While trying to portion control in the morning, it was not obvious at lunch time at l’Astral restaurant, the revolving restaurant at the top of Loews Concorde during a visit in Quebec City.  I succeeded to skip the appetizer counter and went directly to the meat counter. Once again, the dessert plates were a blast. 1 filled the fiste one with fresh berries and chocolate, but the other one assembled with samples of cakes and the unforgetable crepes with maple sirup, a must. Ouf!

Brunch Astral Loews

Fortunately, we took a long 4 hours walk in the afternoon. Exhausted, we stopped at a pub for some rest and a pint of beer. Then headed to a pizzeria: 4 slices of thin crust veggies pizza, and Pellegrino water. No appetizer, no dessert. Overall, many extra calories for the all day. 

Back home the day after, the ultimate test was to weigh again on the scale.  As usual, measured in the morning, naked, after going to the toilet for eliminating fluids and solids,  before coffee and breakfast. Then again the day after, for confirmation  Result: gain of 0,5 lb or 0,2 kg. I would have not being surprised with a 1 lb gain, like it was the case previous years, 2 lbs the first year.

Now, it is time to reverse the situation this week with serving smaller meals,  so I return to my pre bootcamp stable weight as soon as possible. So, quick adjustments, after monitoring little weight gain. This is the kind of strategy used by those who succeed to maintain their weight over time.

Awareness is the key point. Being reasonable on portions, compensating  sweet indulgence  with exercise, choosing as much vegetables as you can on each meal, fish meals at least two times, controlling fluid intake, especially sweet-beverages and alcohol, proteins and fresh fruit at breakfast, dairy products every day especially for breakfast, no snacking, no binging.

How do you manage your food intake in such situation? I would be happy to hear your strategies and to told if you succeed.
