Low carbohydrate food labeling



If you want to lose weight and have a healthy body, it is important that you are mindful of the type of food you eat. If you are on a low carbohydrate food diet, then you need to make sure that the food you buy and consume meets the specifications of your diet. We rely on food labeling to inform us about the content of our food. How accurate are these food labels? Do we take the time and effort to read and understand them before we buy the food?

What to Look at in Low Carb Food Labels

Some people argue that these days some of the labeling about so-called net carbohydrates in various low carbohydrate foods is simply designed to promote and sell more products. This is debatable. So the key question is:

Low carbohydrate food labelingDo food labels actually provide the customers with the accurate information? There are also customers who simply do not look at the details about the contents of the food as stated on the labels. It is strongly recommended that you read the low carbohydrate food labels and understand them, so that you buy and eat what is suitable for you and your diet.

Once you start a diet, you must read the low carbohydrate food labels, and be informed about how the products are actually manufactured.

Some low carbohydrate foods are labeled low carbohydrate foods attain lower carbohydrates by their method of carbohydrate counting; and this is fact you must know. Some of the labels list total carbohydrates, then eventually subtract certain items from the total to arrive at net, effectual, or usable carbohydrates. This is the number that is always shown on the front of the food pack.

On food labels, do you know the difference between the total carbohydrate and the net carbohydrate? There is a wording somewhere on the low carbohydrate package that explains the difference between these two. Amongst the nutritionists and experts, there are some disagreements on the calculating method. Due to the fact that there is no legal definition of the term low carbohydrate or any official means of distinguishing it, most of the low carbohydrate food consumers are not well informed or given good advice.

In order for you to fully comprehend the low carbohydrate food labels, you must know the net carbohydrate content of the food item. Net carbohydrate content is derived from subtracting the grams of fiber and sugar alcohols from the total carbohydrates. The reasoning behind this is that many of the low carbohydrate food manufacturers believe that fiber, while technically a carbohydrate, is not absorbed by the body, and therefore must not be measured as carbohydrate.

As far as sugar alcohols are concerned, the low carbohydrate food manufacturers believe that although these are technically carbohydrates and a source of calories, they have an effect on the blood sugar, and therefore must not be added up as carbohydrates.

Because some of the food labels are not very clear while some are not so easy to understand; it is recommended that instead of buying and consuming large quantities of processed low carbohydrate foods, such as low carbohydrate protein bars and low carbohydrate mixes or drinks, you are better off eating natural low carbohydrate foods such as vegetables, fruits, and whole grains.

If you want to eat low carbohydrate, it is better for you to get away from all processed foods, including low carbohydrate processed foods. Alternatively, be very vigilant in reading food labels and make sure you understand them. Some of the net carbohydrate statements may be a marketing ploy, and the content label may not be essentially a good description of what’s actually contained in these food products.

It is your body, it is your health. Be vigilant in reading the low carbohydrate food labels and be informed about what you are eating!

Fast Food Diet Study



I found this great study and article from the people at ABC News about a Fast Food Diet Study.

This study was purposely having people eat fast food to determine its affects on obesity

Researchers at Washington University School of Medicine in St. Louis are making an unusual offer: They are paying people to add fat to their own bodies by eating an extra 1,000-calorie fast food meal each day for three months.

Dr. Samuel Klein, the lead researcher in the study, wanted to do some basic research on why only some people who gain weight develop diabetes and hypertension, while others do not. It’s something he said he couldn’t research by feeding food pellets to lab animals.

Testing Moves from Animals to People

“What you learn in rodents does not always translate to people,” Klein said. “What you learn on flies and worms won’t translate to people.”

“[Fast food restaurants] have very regulated food content,” said Klein, the lead researcher of the study. “We know exactly the calories and macro-nutrient composition within fast food restaurants, so it’s a very inexpensive, easy and tasteful way to give people extra calories.”

There was also a cash incentive. Participants could earn up to $3,500, depending on how long it took them to reach the weight goal. They had to gain 5 percent to 6 percent of their body weight during the three-month span and then they could work to shed the pounds again. Researchers monitored their weight from week to week.

Who Volunteered for Fast Food Diet Study?

When the hospital put out an ad seeking participants, several people came forward.

Dawn Freeman, a 50-year-old nurse who has now finished the program, started out weighing 170 pounds. She said she gained 16 pounds over the course of eight weeks during the fast food diet study.

She was compensated a total of $2,650 for her effort, including $50 to lose all the weight again, which she did with diet and walking exercise to help her get down to 162.8 pounds. The hospital guides participants through the weight loss.

Freeman said gaining weight fast — with a doctor’s persmission — only sounds easy and even seemed easy with the first meal, a Big Mac and large fries from McDonalds.

“It was really good and you know the next night I went to Taco Bell and it was, it was wonderful,” she said. “This is after I have already eaten dinner.”

But Freeman eventually found out that gaining weight in a hurry was hard, something Klein predicted.

“This is not pleasant for them,” Klein said. “It’s not easy to stuff your face every day for a long period of time.”

Freeman said she started to feel awful after two weeks, “I could hardly breathe anymore.”

She is glad it’s over. But another participant, Dave Giocolo, was about to find out that this experiment was not a food lovers’ dream.

The 48-year-old bathroom design and supply salesman said when he heard the medical school’s ad on the radio while commuting to work, he called them right away.

The St. Louis native starting weight was 249.9 pounds, with a goal of adding about 15 pounds for the study. So Giocolo, who never went without his morning McDonalds breakfast burrito, started eating quarter pounders for the sake of science.

What do you think of the value of fast food diet study like this? I am glad I am not a test subject but anything like this will likely teach us more about how people react to processed foods and higher fat diets in a more controlled setting

Why Does Exercise Sometimes Not Help Weight Loss?


There’s no doubt that exercise burns calories. So why has study after study found such modest average weight loss even after subjects follow relatively vigorous, well-designed exercise programs?

The usual answer is that you unwittingly eat more to compensate for your workout. That’s partly true, but it skims over a vital detail: Few of us are “average.” Break down the study results, and you find that exercise is highly effective at melting off pounds for some people, and ineffective for others. Scientists are now teasing out the factors that explain these different responses – and poking holes in weight-loss plans that promise one-size-fits-all success.

Why Exercise Changes sometimes Fail

“There’s currently a strong interest in identifying ‘behavioural phenotypes’ within the obese population so that treatments can be more specifically targeted,” says Graham Finlayson, a biological psychologist at the University of Leeds. “This is the case for exercise, food, diet, pharmacologic and surgical approaches.”

Why Does Exercise Sometimes Not Help Weight Loss?

Exercise and Weight Loss

The wide variability in response to exercise is shown clearly in the results of a 12-week program of supervised exercise, published in a review co-authored by Dr. Finlayson in the British Journal of Sports Medicine last month. Although the intensity and duration of each workout was the same for all 58 subjects, some lost more than 10 kilograms while others actually gained a small amount of weight – opposite extremes from the average loss of 3.2 kilograms.

I myself think that there is a correlation between food and exercise that is very tight. I have gone through changes where I am very physically active and I eat to compensate for the calorie loss. Keeping a very disciplined eating schedule to conteract any problems with metabolism and Leptin depletion are essential.

Dr. Finlayson and his colleagues suggest a long list of possible reasons for the variation. There are physiological possibilities, like the rate at which food leaves your gut; the production of appetite hormones like leptin and ghrelin; and the extent to which your body relies on fat versus carbohydrate for energy. All of these are affected by exercise and could influence appetite and food intake, though the evidence remains contradictory.
