My Health For Life Program at Stafford

I’m excited to announce that I will be facilitating a My Health for Life Program at Minds4Health in Stafford starting on Friday 5th October.

The My Health for Life Program is a free program for people over 45 that are at risk of developing a chronic health disease and would like to make lifestyle changes to live healthier and reduce their risk.

The (mainly) group program provides support to participants while they decide and start making lifestyle changes that they want to make. Many participants find the group program very supportive. Support people are welcome and encouraged to come to the program.

The program consists of one individual consultation with the facilitator and 5 group sessions over 6 months.

If you would like to be eating healthier, moving more, coping better, smoking less or not at all, drinking alcohol moderately or losing weight this program might be for you.

The program is funded by Queensland Health and there is a quick survey that can be done over the phone with Cathie to see if you are eligible.

Cathie Lowe is a My Health for Life Facilitator and an Accredited Practising Dietitian. If you would like to know more about the program and eligibility please contact Cathie directly on 0409628551 or emailenquiries@minds4health.com.au or for general information call My Health For Life on 137475.

Sleep is Really, Really Important!

canstockphoto15729484In a new journal article Alyssa Lundahl and Timothy Nelson look at how poor sleep quality and quantity affect the human drive to eat.

The take home message is if you don’t sleep well – try to get help as is has a big impact on your food choices in many ways.

Biologically, researchers have found that disrupted sleep can lead to a 20% increase in the amount of calories people eat and that portion sizes are bigger.  It appears that 2 hormones control most of this higher drive for food.  Lower levels of Leptin (tells our brain we how  satisfied we are with what we’ve eating) are found in stressed adults with disrupted sleep and higher levels of Grehlin (tells our brain we are hungry) occur.  This makes people look for more foods that are sweet, salty or starchy.  Researchers have found other hormones also are changed with poor sleep including cortisol, insulin, glucocorticoids and these also make us change our food choices.

If we don’t sleep well, our ability to think is reduced in several ways and can lead to adults and children eating more foods and for children looking for higher calorie snacks.  Poor sleep affects a part of the brain that helps us with goal directed behaviours and being able to moderate our impulses and emotions.  So it is harder to talk yourself into doing healthy goals like going for a walk, eating more vegetables and harder to say no to tempting higher calorie foods.  Another part of our brain is disturbed with poor sleep, making the brain want more rewards to pleasurable stimuli – so we want that pleasurable sensation from tasting of sweet or  fatty foods more than usual.

Poor sleep affects our emotions.  You are more likely to notice negative events and negative emotions and be emotionally distressed when you have slept poorly. I don’t think it would be a surprise to many people that when feeling negative emotions, adults and children tend to eat more foods. The changes in eating patterns are eating less fruit, vegetables and breakfast cereals and eating  more sugary or high fat foods.

The way humans behave is changed when sleep quality or quantity is poor.  Adults and children are more likely to behave impulsively and plan less when they are tired. So when you are tired it is harder to resist tempting foods if you have an impulsive personality and you will tend to eat more food then you may have wanted or planned to.

So if you are trying to make healthy eating or lifestyle changes, try to get enough undisturbed sleep so that you won’t have extra hormonal, thinking, behavioural and emotional challenges.

Does Caralluma fimbriata extract help with weight loss?

I was asked about this herbal extract recently.  It’s being marketed in a weight loss supplement at the moment. 

Caralluma fimbriata is extracted from an edible cactus that is grown in India.  It is marketed as an appetite suppressant that will help people lose weight.  In the supplement on the market in Australia the dosage is 6g of Caralluma fimbriata.

So let’s talk about the research available on this extract. 

Remember that in the pharmaceutical industry a drug cannot be sold until there are several long term studies.  A good solid study would have at least 1500 volunteers with at least half receiving the active study drug, half receiving a placebo “non active” tablet, with the side effects closely monitored and results documented for at least 1 year.

There was one study on humans that ran for 60 days.  Fifty overweight volunteers were in the study with half receiving placebo. The dose of the extract was 1g per day.    The study found that there was a significant drop in waist measurement and appetite and a trend of weight loss that wasn’t statistically different between groups.

The only other study was on 18 rats.  The rats were given two different types of food (pellets or pellets and “cafeteria style food”  and given differing doses of Caralluma fimbriata for 90 days and there was an effect on appetite on the 3rd week of taking the extract in the highest dose and less weight gain in those receiving Caralluma fimbriata.

Bottom line:
This extract may or may not help with weight loss, there’s not enough research. There haven’t been any long term studies to show what kind of weight loss could occur and be sustained at 1 year.  Side effects are unknown at this stage.  It is constantly amazing how herbal extracts can be marketed as helping with weight loss with very small research studies compared to the medications that a doctor can prescribe.
