Should You Consume Caffeine to Lose Weight?

People seeking to lose weight are typically anxious to hear about any trick to make weight loss easier. One way to help speed weight loss is to find ways to speed up the metabolism, so that more calories are burned in a day.

Research has shown that caffeine is effective at speeding up the metabolism, so that you burn more calories. According to the Mayo Clinic, caffeine stimulates many body functions, including the heart rate, central nervous system function and metabolism. In addition, caffeine may decrease the appetite short term. So, adding caffeine may be an effective way to jump start weight loss. There are some things to consider, however:

You may see no effect if you’re already a caffeine consumer. If caffeine is already a part of your daily diet, you would likely need very high doses of caffeine to increase your metabolism above the level at which it already functions. However, those who don’t regularly consume caffeine may see some benefit.

You must be careful where the caffeine comes from. If you start getting your caffeine from sugary sodas, you’ll likely gain weight rather than lose it. However, if you get your caffeine from coffee, tea and sodas without sugar, you may see some results.

You must consider your other health issues. If you already suffer from an irregular heart rate or high blood pressure, your doctor may have warned you to stay away from caffeine. If this is the case, caffeine may not be safe for you. Be sure to talk to your doctor before adding caffeine.

What if I’m Caffeine Sensitive?

Many people stay away from caffeine because they find that too much caffeine causes sleeplessness or jitters. For these people, supplementing with caffeine for weight loss might seem unreasonable. However, there’s one form of caffeine that seems to be tolerated well by those who are normally caffeine sensitive.

Green Tea May Be the Answer

Green tea may well be the best way to get your caffeine for weight loss. Though green tea does contain caffeine, it is in smaller amounts than many other beverages. In addition, the caffeine in green tea seems to be better tolerated by the caffeine sensitive than other caffeinated beverages. This is thought to be because of the anti-oxidants in green tea.

These anti-oxidants, in addition to making the caffeine less of a problem, also offer a myriad of health benefits. Green tea’s anti-oxidants have been shown to lower cholesterol and prevent heart disease and some forms of cancer. So, even if you don’t lose weight from drinking green tea, it’s a healthy habit to add to your diet.

But, the best news is that in addition to being healthy and well tolerated by the caffeine sensitive, it may just be that green tea is the best way to get your caffeine for weight loss. This is because studies have shown that green tea is more effective in promoting weight loss than other caffeinated beverages. The combination of caffeine and green tea’s anti-oxidants appears to be more effective in promoting weight loss than caffeine alone.

One important study on this subject was reported by the Obesity Research Group. In this study, ninety overweight men and women were studied. First, the group was put on a low calorie diet for four weeks. The subjects were divided between low caffeine consumers and high caffeine consumers. At the end of the four week diet period, the subjects were placed on a weight maintenance program.

During this weight maintenance period, subjects either received a green tea/caffeine supplement or a placebo. Within the groups, both high caffeine consumers and low caffeine consumers were given the green tea/caffeine supplement. The weight maintenance period lasted for 3 months.

At the end of the study, the results were as follows:

o Caffeine consumers overall seemed to have higher satiety levels and lower leptin levels, which helped speed weight loss.

o During the weight loss period, caffeine consumers lost more weight than non-caffeine consumers.

o During the weight maintenance period, the low caffeine consumers who received the green tea/caffeine supplement kept off more weight than the low caffeine consumers who received the placebo. In fact, many of them continued to lose weight.

o During the weight maintenance period, the high caffeine consumers who received the green tea/caffeine supplement did not report a significantly higher success rate in keeping the weight off than those high caffeine consumers receiving the placebo.

While more research is needed to truly determine how green tea and caffeine can help with weight loss and maintenance, it does appear that consuming green tea and other forms of caffeine can help you lose weight. In particular, caffeine and green tea may be especially effective for those who don’t consume a great deal of caffeine on a regular basis. And, since green tea is a form of caffeine that is well tolerated by most caffeine sensitive people, green tea may be the best way to use caffeine as a weight loss aid.

You have nothing to lose by adding green tea to your diet. It’s healthy, refreshing and has no side effects. And even those who are sensitive to other forms of caffeine can usually drink green tea without experiencing unpleasant side effects. So, see if green tea can help you in your efforts to lose weight!

Caffeine Blues – Caffeine Withdrawal Anxiety

Here is another excellent article from a contributing author in regards to caffeine withdrawal anxiety and its side effects. Here at caffeine withdrawal .org we hope to provide our readers with up to date information and article in regards to caffeine and caffeine withdrawal symptoms

Caffeine Blues

By Stephanie Relfe

Okay, I know this article won’t be popular. Most of us are so addicted to Caffeine that we don’t want to know about it. I am writing this because when “Caffeine Blues” by Stephen Cherniske M.S.came out I just knew I had to read it. Several years ago I began to realise that coffee was much worse than we had been told, because I noticed that I got an arthritic pain in my wrist within ten to twenty minutes of a cappucino!

This book didn’t just tell me how bad coffee was – it told me how GOOD I would feel once I was totally caffeine free for two months. Somehow, this book sold me on giving it a try. And it was right! For example, I no longer have the drained feeling that I sometimes used to get in the mornings.

This is one of the best health books I have ever read. It is written by Stephen Cherniske who is a Clinical Nutritionist. “Caffeine Blues” is incredibly easy to read, and convincing. After reading it I realized that caffeine does NOT give us energy. In fact, it is a major CAUSE of LACK of energy. However, he explains that this drug is so powerful that one needs to go for three weeks to two months without any caffeine before one notices the difference. And how many of us have ever done that? Hardly anyone.

As Cherniske waded through the tons of information on caffeine, he began to see that consciously or unconsciously nearly every researcher starts from the assumption that caffeine is okay. Why? Probably because they themselves depended on caffeine.

Caffeine is in coffee, tea, chocolate, colas, chuppa-chups, many sodas, some drugs, most ‘energy’ drinks and guarana.

A 6 oz cup of:

Percolated coffee has about 120 mg of caffeine

Black tea has about 70 mg of caffeine

Green tea about 35 mg of caffeine

Leading colas 45 mg of caffeine

Mountain dew 54 mg of caffeine

Brewed decaf has 5 mg of caffeine

Milk chocolate has 6 mg per ounce

Baking chocolate has 35 mg per ounce.

Caffeine is produced by more than eighty species of plants. The reason may well be survival. As it turns out, caffeine is a biological poison used by plants as a pesticide.

Caffeine is considered harmless simply because it is so widely used.

There is a brochure available in hospitals and other medical related areas: “What you should know about caffeine” published by the International Food Information Council (IFIC) in Washington DC. After many phone calls Cherniske finally got a list of ’supporters’ of the IFIC. The list included Pepsi, Coca-Cola, M&M, Nutrasweet, Nestle and Hershey – all of whom have caffeine in their drinks and foods. ‘Partners’ of the IFIC included groups such as the National Association of Pediatric Nurses and the Children’s Advertising Review Unit of the Council of Better Business Bureau Inc. This brochure says that “Caffeine is normally excreted within several hours after consumption”. In fact, only 1% is excreted. The remaining 99% has to be detoxified by the liver.

It can take up to 12 hours to detoxify a single cup of coffee.

Many studies regarding coffee and hypertension were flawed, because the test studies came off coffee for only one or two weeks. It takes many more weeks than this for stress hormone levels of the body to return to normal.

The ‘half-life’ of a drug is the time it takes the body to remove one half of the dose. Caffeine is a drug. The half-life of a single dose of caffeine ranges from three to TWELVE hours.

Caffeine puts your body into stress. A single 250 milligram dose of caffeine (the equivalent of about 2.5 six ounce cups of coffee) has been shown to increase levels of the stress hormone epinephrine (adrenaline) by over 200%.

Caffeine triggers a classic fight-or-flight reaction. The fight-or-flight response was designed for events that happened only occasionally (such as a lion chasing you). Now, we put our body in fight-or-flight every day with caffeine!!! Since we are in society, we don’t respond in a fight-or-flight way. Instead, other things may happen. For example, sugar and fat get dumped unused in the bloodstream. The sugar creates more stress. The fat clogs the arteries. The digestive system slows or shuts down.

Not only is caffeine addictive, it also encourages other addictions to substances like nicotine.

Caffeine does not give you energy. It stimulates your nervous system and adrenals. That’s not energy, that’s stress. Imagine going to a bank for a loan. The loan officer agrees to your loan. But as you leave the bank you notice the fine print – the loan has to be repaid at 75% interest! The ‘energy’ that you think you get from caffeine is really just a loan from the adrenals and liver, and the interest you have to pay is very high.

Stress is a major factor in disorders such as anxiety, insomnia, depression, ulcers, rheumatoid arthritis, headache, hypoglycemia, asthma, herpes, hypertension and heart disease. And yet hospitals provide coffee and tea, which put your body into stress!!!

DHEA is our vitality hormone. Decreased levels of DHEA is a cause of aging. Caffeine consumption leads to DHEA deficiency.

Caffeine lowers the stress threshold in virtually everyone. That is, if you have had caffeine, it will be easier for you to suffer from emotional stress. (Therefore, when research is done that is designed to show how safe caffeine is, any test subject who is under significant stress is removed from the study).

Caffeine is implicated in ulcers and irritable bowel syndrome: GABA is produced in the intestinal tract, where it calms anxiety and stress. Caffeine disrupts the normal metabolism of GABA.

Caffeine disrupts sleep. Deep sleep is CRITICAL to good health. When there’s caffeine in your bloodstream, you are unlikely to experience deep sleep at all!

Caffeine AT ANY TIME of the day can cause sleep problems, especially if you are under stress.

Malnutrition is one of the most well-defined effects of habitual caffeine intake.

A single cup of coffee can reduce iron absorption from a meal by as much as 75%.

People do not develop a tolerance to the anxiety-producing effects of caffeine. Rather, people simply become accustomed to the feelings of stress, irritability and aggressiveness produced by the drug.

Caffeine contributes to depression in well-defined ways. This is particularly due to the withdrawal effect, which can cause headache, depression and fatigue, even in light users (p. 111). Cherniske reported that 90% of people who came to him who suffered from depression and gave up caffeine completely for 2 months reported that their depression went away!

If you are a coffee (or tea or cola) drinker, you may be thinking, “Well, I drink coffee and I’m not depressed.” It’s necessary to state that everyone is different, and also that depression can be subtle. Throughout the book, Cherniske suggests that you will never know the full effect the drug is having on you until you experience what life is like caffeine free (which takes two months to do). Over the years, Cherniske has heard similar responses from hundreds of clients: “Wow, I never realized that caffeine made me so (select one: anxious, depressed, irritable).”

Students the world over use caffeine not only to stay awake, but also they believe the drug will improve their performance on exams. Solid research, however, illustrates that as little as 100 milligrams of caffeine (one cup of coffee, two cups of cola) can cause a significant DECREASE in recall and reasoning.

When people are relaxed and given caffeine, caffeine does not raise blood pressure significantly. But how many people are relaxed? When people are stressed and given caffeine, blood pressure is raised significantly.

Women who consume more than 24 ounces of coffee (6 moderate cups) per day had almost twice the risk of heart attack compared to non-coffee drinkers. Moderate coffee drinkers with high cholesterol had more than seven times the risk of heart attack, while heavy coffee drinkers had eighteen times the risk of non-coffee drinkers!

Caffeine depletes your supplies of thiamin and other B vitamins, calcium, magnesium, potassium, iron and zinc.

Caffeine increases calcium loss and risk of osteoporosis.

In one large study, the risk for hip fracture for those women who consumed the most caffeine was 300% greater than it was for the group that consumed little or no caffeine.

Take the Challenge! Most people have no idea what life would be like without the background of caffeine and stress hormones coursing through their veins. Even if you’re only having a few cups a coffee, chances are your personality is affected in ways that may be too subtle for you to associate with caffeine. I want to encourage you to conduct a trial period without caffeine. You owe it to yourself.

Don’t’ go ‘cold turkey’. To avoid headaches etc. when giving up caffeine, Cherniske recommends taking up to six weeks to come off it. Drink the same NUMBER of cups, but each week reduce the strength or amount in each cup.

There is lots more information in this very easy-to-read and highly interesting book. 440 pages. Read this book and you won’t need to spend so much on supplements!

Minimize caffeine withdrawal symptoms – a caffeine withdrawal treatment?

Three days ago I switched to decaf coffee and tea. This is in response to my realization that I had developed an addiction and the caffeine is overstimulating my pituitary which is presenting in various symptoms. I started with a headache two days ago that will not go away. I’m also feeling generally lethargic and having withdrawal symptoms.

Any suggestions for minimizing these symptoms? How long will this last?

FYI… I am not a soda drinker. I drink lots of water and I eat a whole foods diet. I also excercise daily.

Migranes and The Caffeine Withdrawal Duration

This is another great article from a contributing author on caffeine withdrawal, it’s duration and length, and some of its side effects. Here at caffeine withdrawal .org we hope to provide our readers with the most up to date information on caffeine and its effects.

Caffeine Withdrawal and Migraines

By Darren Williger

When it comes to migraines, or similar “caffeine headaches”, caffeine is one strange drug. The headache associated with a migraine needs to be triggered. This trigger can come in many forms: certain foods, weather conditions, lighting. One of the triggers is too much caffeine consumption. And yet the pain of migraines can also be lessened by ingesting caffeine. Talk about your two way streets!

The number one cause of migraines that are related to caffeine consumption is caffeine withdrawal. The good news is that this presents two methods of using caffeine to actually prevent migraines. The first method is the least difficult in theory, but probably the most difficult in practice: reducing the amount of caffeine you take in. If you don’t take in a lot of caffeine, you don’t suffer much in the way of withdrawal symptoms. It sounds easy because all you have to do is cut down on the caffeine. But saying you’re going to cut your caffeine, wait for a certain duration, and actually going through with it are two different things.

There is another method and though it sounds more difficult, in practice it’s probably a lot easier than cutting down completely. The second method is all about ensuring that withdrawal never becomes a problem. You can do this by timing your intake of caffeine over time. If you ingest a certain amount of caffeine at specific intervals throughout the day your body will be satisfied and keep the migraine headache at bay.

Some migraine sufferers have been tempted to go cold turkey, disregard the caffeine withdrawal duration, and engage in complete and utter caffeine abstinence. This sounds like a pretty good idea. But, let’s face it, abstinence always sounds better than it actually turns out. Theoretically, there is absolutely no downside to the abstinence program; it’s only when you start applying it to the real world that you get in trouble. For one thing, caffeine is addictive. The more you get, the more you want. And many times this urge is just too overwhelming.

An even bigger obstacle is that it’s almost impossible to completely abstain from caffeine unless you are detail-oriented to the point of psychosis. If you are planning on abstaining from caffeine as a means of staving off migraines, you’re going to have to do more than simply give up your coffee or soft drinks. Caffeine is everywhere in today’s society. You’ll have to keep a watchful eye on the ingredients of chocolate candy, pain-relief medicine and diet pills. And that’s just the start. You can also add such things as liqueurs, energy drinks and even pudding to the list!

By this point you may rethinking that whole idea of keeping track of your ingestion. The timing schedule sounds more difficult, but consider this: would you rather keep track of how often your ingest caffeine over the course of a day, or keep track of the thousands of products that contain caffeine?

The caffeine infusion method simply means that you keep count of how often and how much caffeine you put into your body. Once you figure out how much you need and when you need, your migraines should become a memory. Provided, of course, of that you have determined that caffeine is your migraine trigger. There are some tips to make this process easier.

First off, if your primary delivery system for caffeine is coffee, you’re in for some bad news. Determining how much caffeine you are getting in a single cup of coffee is almost impossible and in this method you really want to be precise. Therefore, computing the caffeine figures is easier if you get your caffeine by way of either soft drinks or caffeine tablets. Which of those you prefer is up to you. Some people don’t like soda, so the tablet is a better way to go.

On the other hand, most people probably prefer to get their caffeine along with a little liquid refreshment. Whichever means you decide on, here’s what you do next. Keep a little diary in which you note when and how much caffeine you consumed, along with information about any headaches you got; things such as time of day, how long the headache lasted, how severe it was, etc. This information will be your guide in determining when and how often you need that caffeine to keep the migraines away.
