Artificial Sweeteners Once Again Linked to Weight Gain

artificial sweetenersFoods and beverages that contain no-calorie artificial sweeteners may be ruining your ability to control your food intake and body weight, according to new research by psychologists at Purdue University’s Ingestive Behavior Research Center.

In their study, when compared with rats that ate yogurt sweetened with glucose (a simple sugar), rats that ate yogurt sweetened with the zero-calorie artificial sweetener saccharin:
  • Consumed more calories (and didn’t make up for it by cutting back later)
  • Gained more weight
  • Put on more body fat
It’s thought that consuming artificial sweeteners breaks the connection between a sweet sensation and a high-calorie food, thereby changing your body’s ability to regulate intake.

The researchers also measured the rats’ core body temperatures, which typically rise after eating. However, after eating a sweet, high-calorie meal, rats that ate saccharin had a lower rise in body temperature than rats that ate glucose.

The researchers believe that this blunted biological response led the rats to overeat, and made it harder to burn off the calories later.

They concluded that consuming foods sweetened with saccharin would lead to greater weight gain and body fat than eating the same foods sweetened with sugar.

Although further research needs to be done, the researchers believe that consuming other artificial sweeteners such as aspartame, sucralose, and acesulfame K would have similar effects.

Dr. MercolaDr. Mercola's Comments:
The evidence just keeps pouring in that consuming artificial sweeteners will likely wreak havoc on your body by impairing your ability to regulate your appetite naturally. Just take a look at last week’s article that found drinking diet soda increases your risk of metabolic syndrome and, ultimately, heart disease.

Folks, the belief that eating artificially sweetened foods and drinking artificially sweetened beverages will help you to lose weight is a carefully orchestrated deception. So if you are still opting for diet choices for this reason, you are being sorely misled.

In reality, these diet foods and drinks ruin your body's ability to count calories, thus boosting your inclination to overindulge. Unfortunately, most public health agencies and nutritionists in the United States recommend these toxic artificial sweeteners as an acceptable alternative to sugar, which is at best confusing and at worst harming the health of those who take their misguided advice.

Consider what the research says:
Yet, gaining weight is only one of the side effects of consuming these man-made chemical sweeteners.

The Toxic Dangers of Artificial Sweeteners

There is enough evidence showing the dangers of consuming artificial sweeteners to fill an entire book -- which is exactly why I wrote Sweet Deception. If you or your loved ones drink diet beverages or eat diet foods, this book will explain how you've been deceived about the truth behind artificial sweeteners like aspartame and sucralose -- for greed, for profits ... and at the expense of your own health.

What’s wrong with those tiny pink, blue and yellow packets? Well, take aspartame for instance.

The phenylalanine in aspartame dissociates from the ester bond and increases dopamine levels in your brain. This can lead to symptoms of depression because it distorts your serotonin/dopamine balance. It can also lead to migraine headaches and brain tumors through a similar mechanism.

Furthermore, the aspartic acid in aspartame is a well-documented excitotoxin. Excitotoxins are usually amino acids, such as glutamate and aspartate. These special amino acids cause particular brain cells to become excessively excited, to the point they will quickly die. Excitotoxins can also cause a loss of brain synapses and connecting fibers.

Then the ester bond in aspartame is broken down to formaldehyde and methanol, which have their own toxicities. So it is not surprising that this popular artificial sweetener has also been found to cause cancer.

So aside from causing you to gain weight, artificial sweeteners may cause all sorts of nasty side effects to your health.

How to Kick the Artificial Sweetener Habit

If you consume a lot of diet foods and beverages, it’s likely because you have sweet cravings (yet you think you are making a healthy choice by avoiding sugar).

Your body, however, is craving sweets because you are not giving it the fuel it needs. Finding out your nutritional type will tell you exactly which foods you need to eat to feel full and satisfied. It may sound hard to believe right now, but once you start eating right for your nutritional type, your sweet cravings will disappear.

Meanwhile, be sure you address the emotional component to your food cravings using a tool such as the Emotional Freedom Technique (EFT). More than any traditional or alternative method I have used or researched, EFT works to overcome food cravings and helps you reach dietary success.

And, if diet soda is the culprit for you, be sure to check out Turbo Tapping, which is an extremely effective and simple tool to get rid of your soda addiction in a short period of time.

If energy psychology techniques do not work, then you might want to consider a medical hypnosis program I have evaluated and found to be highly effective.  It has direct suggestions to replace soda cravings with cravings for pure water.

I spent most of the last 30 years avoiding sugar like the plague, eating whole wheat bread (because I have hated white bread since a kid), extremely low fat and probably very little HFCS but using tons of artificial sweeteners, swigging diet drinks etc and ended up well over 100lbs overweight.  More human studies need to be done my foot...just ask those of us who are obese what we did to get that way!!!

Your experience Patty further proves my empirical point that The Glycemic Index is a failed marketing scale, not based in science or medicine, as it fails to measure total caloric intake in a specific individual, or of a specific metabolization, or of a specific genetic predisposition, over a specific period time, or ANY specific ingredient ingestion, or combination of ingredients, or food, or beverages.

Again, the link one can read entitled: STUDY CAST DOUBT ON GLYCEMIC INDEX by John C. Drake of the Associated Press can be found on most search engines like www.altavista.com or www.google.com   Published Wednesday, March 1st, 2006 from the University of South Carolina's Arnold School of Public Health, published in the February Issue of 2006 of the British Journal of Nutrition by Dr. Mayer-Davis

Patty, I can relate!

We had no soda at home until I was ca.12 then my mother allowed one bottle each weekend (just 700 cc), as a treat shared between two. It was only when she joined WeightWatchers that we started getting artificial sweeteners. They were so awful-tasting that I just gave up sugar in tea and coffee.

Around that time my best friend kept telling me I was fat (not true) so I used meal replacements full of artificial sweeteners to lose 7lbs in a week, and gained 2x back in a month each time. Later at drama college, fad-dieting central, a straight diet tonic became my 'usual'. I congratulated myself on choosing such a 'healthy' option! We got big bottles of Tab and slimline tonic at home and I wondered why I just kept getting fatter.

I've tried fad after fad and believed for years that low-fat and 'sugar-free' meant healthy.

A light dawned about 12 years ago; I made a resolution to STOP DIETING. Healthier eating, no more 'diet' foods - and I stopped getting fatter!

I had a heavy smoker colleague who was in hospital for 3 days. She didn't miss the smoking but had her husband smuggle in a 6pack of Diet Coke every day. My lifelong obese brother always has a big supply in his car. A friend's daughters set up a lemonade stand, selling foul-tasting (to me) Aspartame-laden shop-bought nastiness. When I gave them some of my lemonade, made with lemons (what?!), sugar and water, they spat it out.

My daughter has friends over who seem perplexed that we have no soda in the house, diet or otherwise. I relent sometimes, for Christmas and birthdays, but never the diet versions.

Russ, I dabbled with the GI approach a few years ago and we (the group) were told to avoid all fizzy drinks including diet drinks because of their effects, and because having fake sweetening will not help re-educate the sweet-junky. One of our group got severely told off for recommending a drink she thought was 'just mineral water and a bit of vanilla - no sugar and it's not sweet at all', which turned out to be diet cream soda! Not sweet??

I'm surprised to hear that the Glycemic Index recommends diet drinks; I don't have a list to hand.

While I agree that the G Index is not the whole story, it does act as a fairly good starting point for those completely in the dark about blood sugar spikes, insulin resistance, etc. Some obese seriel dieters I talk to are incredulous when I tell them that their 'healthy, eat-all-you-like diet soup', made of pureed cooked root vegetables, is more fattening than a portion of, say, broccoli with cream and cheese on top.  Perhaps you would disagree if the calorific value of the latter is higher?

However, I will read the study you recommend. Thanks for the info.

LadyPam,

I just wanted to say that after my son was born (before I found Mercola.com) I ate those "replacement meals" and drank those shakes... I turned into a raging lunatic. I am hypoglycemic and didn't realize the amount of "sugar" in those things. I thought I was doing my body good. I shutter to think that I thought that. When I switched to healthy eating, lean proteins and veggies/fruits... foods as they are found in nature (or as close to it) not only did I lose weight, but my attitude improved 10-fold, and so has my health! (My husband and baby thank me).

I am one of those who could never stand diet drinks, and if I eat something with aspartame I have a severe reaction, but I did fall into the sucralose hype... then I found mercola and my attitudes have changed for the better. I strive to teach those close to me what I have learned, but find many of my friends balk at my telling them how bad artificial sweetners are. Everyone wants to know how I lost the weight until I tell them how...by changing my eating habits and exercising. I get tired of being scoffed at for feeding my child healthy choices instead of typical snacks and fruit juices... but maybe someday I will be looked at as a role model, instead, when these same people decide they, too, need a change for their health. Until that day, I just keep striving to educate myself and eat healthy and offer my son healthy choices.

But, but, but this can't be true---medical doctors, the American Diabetes Association, The American Heart Association,  nurses,  certified nutritionists---most everyone in the medical profession has insisted for years that using these artificial substitutes is a good alternative to nasty bad for you table sugar and HFCS.

Whew----just read the last line of the article: "Finally, although the results are consistent with the idea that humans would show similar effects, human study is required for further demonstration."

Oh, good.  Artificial sweeteners are still good for us and OK to use because more human studies still need to be done.  Boy I'm relieved to know this (Darn tongue got stuck again--sorry)

YES, act quickly, all these benefits are yours, for a price, when purchasing and consuming: Sucralose (Splenda Brand), Asulphame Potassium or Ace-K (Sunnet or Nutranova Brands),
Aspartame (Nutrasweet or Equal Brands) and Saccharin (Sweet N'Low Brand), Cocaine Processed Stevia (Nutrition Now, Coke & Cargill Brands)

So whether Yellow, White, Brown, Blue, Pink, Green or whatever, you are shortening your life; and THAT IS PROVEN!

Human sudies still need to be done!!!  Then why is it that when you see someone swigging diet soda or buying it at the supermarket they are usually overweight?

Foxtroter, when I complete my training and qualify as a nutritionist, I can assure you that I will never, ever, ever, ever, advise anyone that these artificial sweeteners are in any way ok. On my own, I may just be a drop in the ocean of nutritional (mis-)advisers, such as NHS-employed dieticians, but we will grow. Oh yes, we will grow!

I'm not decided yet about stevia though my thesis is generally: just get out of the habit of consuming sweet stuff. This would be supported by the article's mentioned theory that breaking the connection between a sweet taste and high calorific food could be compromising the body's ability regulate intake.

I work in a facility that does bariatric surgeries for weight reduction, and artificial sweeteners are a major component of the pre- and post surgical diets. It must be effective to use them in these cases because after surgery, morbidly obese patients melt away their excess weight so quickly it's like I can watch it disappear right before my eyes.

Question for Russ:
(No, Uncle Russ, I'm not gonna do a deja vu on you!)

Friends come to me for advice and someone asked me about Xylitol. I had to confess I knew nothing. Did a search on this site and came up with 0. Did a Google search and could find no evidence of harm. It appears to be made from birch bark and I could find no warnings on line.

So...I'm sure you have something to say. What's the 411?

The only brand I can find that is made all in America comes from birch bark--it is more expensive

The other dozen or so brands that may have plants in America or elsewhere in the world all apparently use corn product as the basis for their xylitol and it all comes from China---my opinion----buyer beware.

I buy the more expensive birch bark made in America xylitol.
