What is the causes of obesity
What is the causes of obesity
The Glycemic Index offers an interesting, and scientifically valid, way of assessing the types of carbohydrates we eat.
It measures and rates the way these carbohydrates enter the bloodstream.
And in doing so offers a way of approaching a meal so that it may be both nutritionally valid, and keep hunger pangs at bay.
This of course is one way of preventing overeating.
And its a great way for parents to try and curb their children’s desire to eat unhealthy food between meals.
What does the glycemic index do?
The Glycemic Index rates carbohydrates as having either a high, low or medium glycemic index.
And the idea is to eat more foods that have either a low or medium glycemic index, and less with a high one.
Low glycemic index foods enter the bloodstream more slowly, and so don’t raise blood sugar levels like high glycemic index foods.
So, what is a carbohydrate?
All sugars, or foods that are broken down into sugar, are carbohydrates.
This includes regular sugar, glucose (often used in sports drinks), fructose, (in fruit), lactose, (found in milk and similar products like yoghurt), maltose, (found in malt which is often used to flavor cereals).
All types of starches, from potatoes to noodles and pasta, and legumes, such as lentils and peas (though these also
contain some protein).
Fruit is considered to have a low GI (not fruit juice though).
Is there a link between fructose and obessity?
Interestingly though, recent research has found what they believe is a link between fructose and obesity.
However, the type of fructose studied was in corn syrup, which is a refined and concentrated form of fructose.
It also doesn’t have the beneficial fiber, antioxidants and other phytochemicals that fruit does.
This was also preliminary research done in an animal model, so it may not be valid for humans.
Researchers from the University of Florida found that fructose may make people believe they are hungrier than they should be.
And when these researchers interrupted the way fructose was metabolized, the rats they were working with did not put on weight, even though they still ate fructose.
This is not the first research that has suggested fructose may be linked to a propensity to put on weight, more so than other types of food.
A study at the University of Cincinnati found that eating fructose (high fructose corn syrup), led to greater fat storage.
They say that the body processes fructose differently to other types of sugars.
Though again, it is not clear if this is mitigated by perhaps the lower concentration of fructose in fruit as compared to the corn syrup used in the study.
The research from the University of Florida found that there were higher levels of uric acid in the bloodstream after eating or drinking fructose.
This spike in uric acid affects insulin, by blocking it. Insulin regulates the way our cells store and use fat.
If uric acid levels are elevated a lot, then symptoms of metabolic syndrome can develop.
These symptoms include high blood pressure, high cholesterol levels, as well as gaining a lot of weight.
Conclusion
What is of possible concern to people is that fructose is used in a lot of soda drinks, so if you drink a lot of soda it is going to be quite easy to frequently spike uric acid levels in the blood.
Metabolic syndrome is also a precursor of type 2 diabetes.
Signs of metabolic syndrome include fat on the abdomen, such that the waist appears as big as the hips or larger.
There tend to be lower amounts of the good type of cholesterol in the blood, and high levels of triglycerides which make the blood ‘sticky’.
Metabolic syndrome is associated with the way the body responds to insulin, so that there are higher levels of glucose in the blood.
All of these things can be tested by doctors.
But there is some new hope for those suffering from obesity.
Just recently researchers discovered breakthrough with a new all natural weight loss supplement called Resurge.

According to a renowned specialist of weight loss, Dr. John Barban, lack of sleep is directly related to the weight gain.
When a person is sleep-deprived, his body experiences multiple changes that lead to imbalances, including weight gain.
Resurge is a popular weight loss supplement that can assist you in improving the quality of sleep and burning excess body fat, releasing and restoring the human growth hormone (HGH) of the body.
It consists of such ingredients that may aid in burning extra fat and restoring the deep sleep.
Now, to lose weight, you do not need to opt for a strict diet plan.
Have a moderate diet and take Resurge supplements do it all for you with no side effects.
Packed with 100 percent natural ingredients, this weight-loss capsule can address other health problems as well.

Great article Vasilios,
All these while I thought that obesity is due to eating too much than what our body needs, I used to be obese as I hangout out with the wrong types of people who eat unhealthy always but never grow fat unlike me. After I changed to eating healthy and eating only 3 meals a day for Breakfast, Lunch, and Dinner, I begin to feel much better. Controlling the amount of fructose is definitely something we all need to consider.

Great to hear you had the discipline to change your eating habits. That is a very difficult thing to do, now your seeing the benefits of eating healthy, great job!

Obesity is truly a problem in the world today and is the cause of so many medical issues. I have struggled with my weight for most of my life and it is not fun.
Your article brought some good points to the table and some great information about fructose. I try to stay away from high fructose corn syrup and now it is easier to find products without it on the grocery store shelves.
I believe that it certainly can be one of the root contributers to obesity. I have not had a soda in several years and I am happy to say that I lost several pounds after letting go of that habit.
Vasilios
Thank you for the compliments. It is great to hear your discipline with not having soda has payed off with losing several pounds. Keep up the great work!

Great article with awesome information! Sugars are not only linked to obesity but also a number of other ailments including cancer. I have read article on webMD and the Canadian Cancer Society or maybe you have an article on this also? I would love to read it if so. Thank you soo much for the article, bookmarked your site 😉
Vasilios
Thank you very much for the compliments, much appreciated! I am glad you enjoyed the information! You bring up an excellent point, sugar is linked to many other ailments. I will look into the webMD article you are referring too. I will write an article on my findings so stay tuned 🙂

Carbohydrate is a very big issue in weight gain. And it is quite addictive too. It is not easy to turn your back from sugar, soda, and all the product full of carbohydrates. That is why people on the Keto diet are having great results because they eliminate all the carbohydrates from their diet.
But I did not know about fructose. And I really appreciate you sharing about it. I guess I will stick with eating natural fresh fruit.
Thanks
Vasilios
Thanks for the compliment Adyns68. Great point about people having great results with the keto diet.
I have a post on my website about the Keto diet i think you would enjoy reading.

Thank you for writing this useful information. I just know that soda has a lot of fructose amount, and it’s not good. How about alcohol? Is consuming alcohol too much can also contribute as another cause of obesity? Soda and alcohol tend to be mentioned a lot by people who want to live healthily, so I could be wrong here. Thanks
Vasilios
Thank you Alblue for the compliment. The main goal for my site is to post useful information that we can all use to live a more healthy lifestyle.
Great question, studies show that light-to-moderate alcohol intake is not associated with obesity, while heavy drinking is more consistently related to weight gain and obesity. Mixing soda and alcohol is also related to weight gain and obesity.
Surprisingly enough, Tequila is actually considered on of the healthiest alcohols. It has a natural sugar called agave.
