This week was quiet on the pregnancy front but so…
Before I decided I wanted a gastric bypass I researched pretty much everything I could about it and I also looked into some things about obesity in general. I have always believed there is more to being obese than it simply being if you eat less and exercise more, then you too can maintain a healthy weight. I have always thought there must be physiological difference in how we are made up and that’s what contributes to some of us finding it much, much harder to easily maintain a normal weight.
I was stoked when I found an exhibit at the Science Museum in London called Cravings and its looking into and showcasing research that’s currently being done into the relationship between the brain and the gut, how we respond to different foods based on their calorie content and how food and addictions have similar effects on the brain.
I have always thought to a certain degree my relationship with food had been one of an addictive nature and if I could just stop one day and never eat again then I’d be happy and wouldn’t miss it. Reasearch being done by Paul Kenny (Neuroscientist) has found that high fat and sugar foods can get the same response from the brain as drugs or alcohol. This does not surprise me in the least.
As well as this there seems to be a relationship between what Mum consumes when you are in the womb and what foods you will find more rewarding later in life. Nicole Avena (neuroscientist) found that pregnant rats who consumed high fat and sugar diets had babies whose brains not only reacted more positively to high calorie food but also were more sensitive to the effects drugs and alcohol.
Scientists are running with this kind of information and are looking at ways that they can incorporate reducing food cravings and the potential effect that may have on reducing cravings for smoking and drinking. Tony Goldstone is an obesity expert and has found ways of controlling cravings through different hormones. If this has flow on effects to treating alcohol and smoking addiction this could be great.
Another piece of Tony Goldstone’s research really interested me because it works in a similar fashion to a gastric bypass. Basically a plastic sleeve is placed into the front portion of intestine which allows food to pass through the small intestine quicker and gets the “I’m full” signals going faster. This is a not so invasive way to get the effects of a bypass without having to change the physiology of the person to achieve similar results. Interestingly they suspect that the sleeve interferes with the hormonal communication between the head and the gut regarding cravings.
It seems that more and more is being realised by researchers about the effects our hormone pathways have on our cravings and how they could possibly be controlled in the future. I really do think that food controlled me before my bypass and it was a losing battle. No amount of willpower was ever going to be enough to out run the stuff that was going on inside my body driving me to eat.
Since having my gastric bypass I have found much to my dismay or delight that my interest in food has seriously waned. I can bake cupcakes and not want to eat them which is so super weird. I have learnt a lot about how my body reacts to cravings now and I’m going to write a follow-up post to this one talking about what influences my cravings now and how I deal with it.
I was really happy to see this exhibit at the Science Museum in London. I think this area of research is really important as obesity is more and more common and the more we know about it the better. I also think research like this can help to bring down social stigma around obesity and bariatric surgery. Are you surprised by any of this information or was it something you suspected all along like I did. Comment below I’d love to know your thoughts on this.
