Do Coffee And Caffeine Inhibit Iron Absorption?

Do Coffee And Caffeine Inhibit Iron Absorption?

Caffeinated foods and beverages have become staples in most modern-day diets. Coffee is among the most popular, with 80% of US adults drinking it (1, 2). Caffeine is a natural stimulant. However, some claim it interferes with the absorption of certain nutrients, such as iron. As a result, some people have been advised to avoid coffee and caffeine. Here’s everything you need to know about how coffee and caffeine affect iron absorption. Several studies have found that coffee and other caffeinated drinks can reduce iron absorption. One study found that drinking a cup of coffee with a hamburger meal reduced iron absorption by 39%. Drinking tea, a known inhibitor of iron absorption, with the same meal reduced iron absorption by a whopping 64% (3). Another study found that drinking a cup of instant coffee with a bread meal reduced iron absorption by 60–90% (4). What’s more, the stronger the coffee or tea, the less iron absorbed (3). However, caffeine alone does not seem to be the main substance interfering with iron absorption. In fact, one study found that caffeine itself only binds to about 6% of the iron from a meal. Given that this is a relatively small amount, other factors must affect iron absorption (5). Furthermore, regular coffee consumption may also have an effect on iron storage levels. A large study found that among elderly people, each weekly cup of coffee was associated with a 1% lower level of ferritin, a protein that indicates iron storage levels (6). However, it’s important to remember that the effects of coffee and caffeine on iron absorption seem to depend on when you drink your coffee. For example, drinking coffee one hour before a meal had no effect on iron absorption (7). Drinking coffee and other caffeinated beverages with a meal is associated w Continue reading >>

Most of us would say we get fat simply because we get lazy and eat more. But what if it's the other way round? What if we just get fat and as a result we eat more and become lazy? For the last decades we have been given wrong advice about nutrition and effects of fatty foods on putting on weight. What if the main problem is that due to our modern diets we cannot satisfy our appetite? A study on this subject concluded with a surprising result: the fatter people get, the more inactive they become, not the other way round. And what if the interests of the authorities offering advice are influenced by economic reasons? To learn more about this, I recommend you watch The Food Revolution on Youtube Ketogenic diets are, in fact, closely related to the Paleolithic diet. Both exclude carbohydrates and aim at eating real food. Today carbohydrates make the majority of our diet and have significant implications for our health including hormone balance. For example, insulin, which is responsible for storing fat in our body, is greatly affected by excessive carbohydrate consumption. Carbohydrates are without doubt the most fattening element in our diets. Based on studies performed over th Continue reading >>

Burning Fat With Bulletproof-keto Tea

Burning Fat With Bulletproof-keto Tea

You may have already guessed I love tea, but coincidentally, I hate coffee. Therefore, when I was first introduced to the idea of Bulletproof Coffee, my brain started whirling about how I could make Bulletproof Tea. More on that below, but first, What is Bulletproof Coffee? The phrase ‘bulletproof coffee’ comes from the website “Bulletproof Exec,” where Dave Asprey, expert biohacker and productivity expert, explores ways to optimize health and maximize efficiency and productivity. Bulletproof Coffee can also be called Keto/Ketogenic Coffee, because it has been used by the low carb community, perhaps even before it was popularized on Bulletproof Exec, as a way to kickstart morning fat burning, and train the body to run on ketones. What are Ketones? When you’re in a carbohydrate-depleted or calorie-deficient state, your body turns to burning stored fat for fuel. When fat is broken down, ketones are released. Ketones can not only fuel every cell in your body, but more importantly, they can specifically fuel the brain. Releasing and using ketones for energy is known as ketosis–the holy grail area for the low carb devotee–a fat-burning, high-energy, clear-mind state of being. And one that reduces body fat! What is in Bulletproof / Keto Coffee? Keto coffee consists of coffee and some form of MCT-dense fat or oil. MCT stands for Medium Chain Triglyceride, and is the closest food substance to ketones; that’s why taking MCTs can help push the body into burning fat, releasing ketones, and using ketones for fuel. (When dietary fat is sufficient, and carbs are low, the body prefers to use stored body fat for energy.) The most popular form of MCT is coconut oil, which is about 65% MCTs. Other coffee additions include butter (less than 15% MCTs), half-and-half, and fu Continue reading >>

It’s 8 a.m. on a recent Wednesday in San Francisco, and Yan Zhu, a 24-year-old blue-haired software engineer, sits at a communal table in a Thai-Italian restaurant munching on a stick of butter. She’s too hungry to wait for food; she hasn’t eaten in 36 hours. “This is my first time fasting, and I was feeling faint, so I brought some butter from home,” Zhu says. Her friend Ayumi Yu (pink hair, 27) explains they’re on a ketogenic diet, which requires eating mostly fat and almost no carbohydrates. “I’ve been on it for a month and feel amazing,” she says. “Take how you feel and imagine feeling twice as good.” Danny Friday, a 23-year-old startup founder, emerges from the bathroom. He’s just done a urine test to check his ketosis levels, which indicate how the body is metabolizing fat. “I’m shocked,” he says, dismayed. “My body is barely in ketosis.” An error has occurred This story is available to Subscribers only.

Will This Kick Me Out Of Ketosis?

Will This Kick Me Out Of Ketosis?

A common question people have when starting keto is “will this kick me out of ketosis?” I’m going to address as many items as I can think of and explain why it will or will not kick you out of keto. This is going to be as comprehensive as possible so either use ctrl + f to find what you’re looking for or buckle up and read on. How do humans enter ketosis in the first place? Things will become much more clear if we explain how humans enter ketosis. Mainly, liver glycogen is what determines if ketones will be produced. Specifically, glycogen in the liver signals malonyl-coa to be formed by carboxylating acetyl-coa. Acetyl-coa is used in many processes and it’s the main substrate used to be turned into ketones. The wiki on regulation of ketogenesis which applies to this scenario says “When the body has no free carbohydrates available, fat must be broken down into acetyl-CoA in order to get energy. Acetyl-CoA is not being recycled through the citric acid cycle because the citric acid cycle intermediates (mainly oxaloacetate) have been depleted to feed the gluconeogenesis pathway, and the resulting accumulation of acetyl-CoA activates ketogenesis.” Basically, when there is more acetyl-CoA than oxaloacetate, the acetyl-CoA becomes acetoacetate, a ketone body. In plain English, carbs provide oxaloacetate, so if it doesn’t have carbs, it likely isn’t going to kick you out of ketosis. I’ll state the exceptions later. Why do humans enter ketosis so readily? Humans enter ketosis faster than any animal on the planet. It usually takes 24-36 hours before we enter ketosis.This is because we have huge brains and tiny bodies. Our brains need ~400 calories/day, which for most people that equates to 20% of our total energy demands. To put this in perspective, most anim Continue reading >>

Perfect Cup Of Ketoproof Coffee

Perfect Cup Of Ketoproof Coffee

Ketoproof coffee is quite a bit healthier than your average breakfast, and it has the calories to match. Commonly used in intermittent fasting, ketoproof coffee gives plenty of energy and a great satiated feeling throughout the morning fasting hours. Now, I want to explain this further. Drinking this coffee will break your fast from the night time, but it will ramp up your metabolism with caffeine and fats. This is to help you get through the fasting process in the 10+ hours ahead. Personally, I drink 2 cups of this in the morning – fast all day – and eat at 9pm. If you’re only using this for breakfast, and still eating a lunch, then it’s not really intermittent fasting. Our favorite brew is made with a pour over and goose-neck kettle. I chose the Bonavita Variable Temp Kettle because it’s on the cheaper side for the quality that you can get. If you’re a coffee lover, it’s definitely worth the splurge! For the pour over, we have an Osaka “Lake Masu” Pour over. It’s really just for the design – I think it looks fantastic. You can easily get a cheap one here that’ll do the same exact thing though. Don’t forget that you’ll most likely need some coffee filters, too. If you’re not a morning person and just want a quick and easy cup of coffee, you can always consider a Keurig Coffee Maker. I’ve owned numerous in the past and they’re great machines if you want convenience. It doesn’t take up much more room than a regular coffee maker and you can usually get small drawers or stands that will hold the k-cups for you. Plus, you can switch up the flavors with just about any type you want! Even though k-cups have come a long way on consumer safety and ecological factors, you still might want to grind your own fresh coffee. Luckily, you can grab a Continue reading >>

Diet Soda And Ketosis

Diet Soda And Ketosis

To be in ketosis, a state in which your body relies on its own fat, instead of carbohydrates, you need to follow a very low-carbohydrate diet. Ketogenic diets have been used for decades to manage epilepsy and promote fat loss. Ketosis is not dangerous, unlike ketoacidosis, a life-threatening medical condition that can affect uncontrolled type 1 diabetics, but you should consult your doctor before starting your ketogenic diet to ensure that it is safe for you. High-carb drinks, such as regular sodas, fruit punches and juices, can all put you out of ketosis, but diet sodas are compatible with a ketogenic diet. Video of the Day A carbohydrate intake below 50 g is required to induce a state of ketosis. Carbohydrates are dominant in the standard American diet, averaging between 200 and over 300 g of carbs a day. Carbs are not only found in sugary foods and drinks, such as sodas, candies and desserts, but also in starchy foods, such as bread, rice, pasta, crackers, pizzas and potatoes. For example, a single can of regular soda contains about 40 g of carbohydrates and could easily compromise your ketogenic diet. Diet Sodas and Ketosis Diet sodas are completely free of carbohydrates and get their sweet taste from sugar substitutes. Substituting your regular soda for a diet soda can help you decrease your carb intake enough to reach the carb range that will help you remain in ketosis. However, you should still carefully track your daily carb intake to stay below 50 g a day if you want your ketogenic diet to be effective. Ketone sticks that you can find at the drugstore can also help you determine whether your diet is effective at keeping you in a ketosis state. Diet sodas are a good option to satisfy your sweet tooth without adding too many carbohydrates, but there are plenty of Continue reading >>

I Drank Butter Coffee For A Month And It Was More Magical Than I Expected

I Drank Butter Coffee For A Month And It Was More Magical Than I Expected

Hi, I'm Sally. For six weeks this summer I started my day with a frothy, oily mug of butter coffee. Butter coffee is made by combining brewed coffee, butter, and coconut oil (or a derivative of coconut oil) and blending it in a blender. When you look into butter coffee's benefits, you get a bunch of people who basically describe feeling like Bradley Cooper in Limitless. People drink butter coffee for lasting energy with no crash, accelerated calorie burning, and a mental boost. And even though I'm not one of those people who's really into experimenting with tiny tweaks that might result in a few more minutes of sleep or a few more calories burned or a few more nutrients absorbed, I am one of those people who's persuaded (with a side of skepticism) by "this changed my entire life" testimonials. • Brew 16 ounces of coffee (I used a French press and this dark roast) • Add brewed coffee to blender • Add 1 tablespoon Kerrygold unsalted butter • Add 1 tablespoon MCT oil (this is a kind of oil found in coconuts and some other foods) • Blend until the mixture is a beigeish color • Pour and drink! Butter coffee also came highly recommended by fitness expert and registered dietitian Albert Matheny of Soho Strength Lab and ProMix Nutrition, especially after I told him that I experience insatiable mid-morning hunger and mid-afternoon fatigue. He said butter coffee tasted good, which I didn't believe. He also said: "I really love butter coffee because it is a more consistent/slower release of caffeine and it is super filling. After an early breakfast — at like 6:30 a.m. — I'm good until lunch at 12 p.m." And that intrigued me enough to want to try it. For context, here's how I incorporated butter coffee into my life: • For six weeks I would replace my normal black Continue reading >>

Perfect Keto Reddit | What You Need To Know

Perfect Keto Reddit | What You Need To Know

Although I most definitely have a stockpile of supplements that I stock, with every little thing from healthy protein powder as well as vitamin D to electrolytes and also BCAAs, I was constantly rather doubtful concerning adding exogenous ketones to that collection. I’ve been keto for even more than two years at this point, so absolutely my body should be a professional at making it’s very own ketones now, right? And of course, the aggressive sales pitches from MLM vendors on social media sites didn’t aid at all; ketosis could absolutely feel enchanting in some cases, however I do not like any kind of supplement being offered as some sort of magic immediate weight-loss remedy. I was constantly curious about them however, so when I lastly found a brand of exogenous ketones that really did not set you back a fortune and really did not need me to sign up with an MLM program, I determined to offer it a try. Perfect Keto Base is designed to offer the advantages of exogenous ketones while “sampling better and also being more economical” compared to various other options. I’ve been utilizing it over the past few weeks, as well as since I recognize a great deal of individuals have questions about exogenous ketones, I figured I would certainly share several of my experience with Perfect Keto Reddit. What Is Perfect Keto Reddit? The primary ingredient in Perfect Keto Reddit is beta hydroxybutyrate (BHB), one of the ketones that your body makes use of for energy while in ketosis. Supplementing with BHB in the form of exogenous ketones elevates your blood ketone degrees, which is connected with improved mood/focus, raised energy, as well as the various other results you may be familiar from a keto way of living (such as weight reduction, reduced desires, etc.). I’ve l Continue reading >>

Caffeine And Ketosis Is Coffee Ok On A Ketogenic Diet

Caffeine And Ketosis Is Coffee Ok On A Ketogenic Diet

You know how it goes; you just can’t start the day without a good strong coffee to get you up and running. But what about the interaction between caffeine and ketosis, does coffee have a negative effect on a ketogenic diet? Or any LCHF diet for that matter. This is a good question not only for coffee but other caffeinated beverages such as soda, energy drinks, and some supplements. The first thing I’d like to address is that there is no scientific study that points to any negative or positive interaction between caffeine and ketosis. However, Dr. Atkins (for which the Atkins Diet is named) does make a point of advising that people consume caffeine in moderation and that caffeine has been shown to cause hypoglycemic reactions in people who consume large amounts of it. Whether that reaction occurs in people who are on Keto or LCHF diets remains to be known. Personal Experience on Caffeine and Ketosis with my Keto Diet From personal experience I see no negative impact on ketosis from consuming caffeinated beverages, I drink probably too much coffee, the odd energy drink and caffeinated sodas from time to time and still maintain a state of ketosis. The best way to know whether or not what you’re drinking or eating is throwing you out of ketosis is to test yourself with a blood ketone glucose meter like this one here about 45 minutes after consumption. It must also be noted that one guy’s experience doesn’t form the basis of credible scientific research, that my friends would be “bro science.” So it’s for you to make the decision about what is best for you. I drink coffee and sodas because I like them, caffeine certainly isn’t purposely put into my diet for any nutritional benefit, and if you can go life without it, I say, “good on you.” What I can say Continue reading >>

Keto Os Review

Keto Os Review

Created by Prüvit, Keto OS, which stands for Ketone Operating System, is a “revolutionary drink mix based on a proprietary ketone energy technology. It delivers advanced macro nutritionals and promotes optimized cellular regeneration, energy and longevity.” [1] Also known as the keto diet, KETO OS is a line of supplements that promise to turbocharge your metabolism and send your body into ketosis without resorting to the draconian no-carb, all-fat diet. The History of Ketones Known for centuries, it wasn’t until a hundred years ago that ketones (Beta-hydroxybutyrate) were used to treat seizures in kids with epilepsy. A “neuroprotective effect” was produced, which calms the nervous system. Soon researchers were exploring an expanded use of ketones to help with mental, emotional and cognitive health, according to Prüvit spokesperson Andra “Dr. Andy” Campitelli , a naturopathic doctor. She says ketone use was expanded as a tool to enhance athletic performance. Ketones result when the body burns fat for fuel. [2] Prüvit on Better Business Bureau There are two Prüvit profiles on the Better Business Bureau site, one in Indiana and one in Texas. Both sell Prüvit products, but have no website link. The Texas profile has an F rating, mostly for lack of response to customer complaints about return issues. The Indiana profile has an A rating, but no reviews or complaints, and it’s only been open a year. Neither profile lists the CEO the same as the website. There is no phone contact on either the Prüvit website or the Texas BBB profile, only an “Ask a Question” form that goes via email. The Indiana profile does have a phone number: (812) 631-4282.

The Morning Cocktail I Drink Instead Of Coffee

The Morning Cocktail I Drink Instead Of Coffee

Try this morning tea cocktail instead of coffee. It’s rocket fuel for the brain. I started experimenting with fat-plus-stimulant beverages in 1998 and 1999 while on the Cyclical Ketogenic Diet (CKD). For the above tea blend, I now add turmeric and ginger to the aged pu-erh, usually Rishi brand. The above video was shot while filming the parkour episode of The Tim Ferriss Experiment TV show. We filmed 13 episodes back-to-back and I needed a morning pick-me-up that could be prepared quickly but sustain me for hours. The tea prep might seem reminiscent of Bulletproof Coffee, and it is. They serve similar purposes. For this reason, I jokingly referred to the cocktail as “Titanium Tea” with the production crew. Alas, BP coffee looks like a delicious frappuccino, and my concoction looks like diabetic horse urine. Here’s why I still drink TT Horse Urine nearly every day: I’m a caffeine “fast metabolizer” according to genetic test results from 23andMe, Navigenics (since acquired), and personal experience. If I drink a cup of black coffee, I feel like a superhero for 30 minutes, then need two cups to get back to baseline. But… When I use a blend of — say — green tea and fermented black tea, I’m combining slightly different pharmacokinetics and biological half-lives, so respective peak plasma (blood) concentrations of stimulants and other compounds are staggered. Instead of one single high point and then a rapid descent into fatigue, I have multiple high points. Rather than feeling amazing for 30 minutes and then fatigued, I can feel 20% more effective for 3-4 hours. This can be extended further if I include a tea like yerba mate (I like Cruz de Malta), which includes three xanthine alkaloids. For our purposes, you can think of these three xanthines as “st Continue reading >>

10 Things That Can Make Incontinence Worse

10 Things That Can Make Incontinence Worse

(Health.com) -- Incontinence can happen to anyone, although it's more common in women than in men. "Mild urinary leakage affects most women at some time in our lives," says Mary Rosser, M.D., Ph.D., an assistant professor in obstetrics and gynecology at Montefiore Medical Center, in New York City. "Although it is more common in older women, younger women may experience leakage as well." You may have stress incontinence, urge incontinence, or some other type. The good news is that there are treatments -- and lifestyle changes -- that can help. Health.com: What type of incontinence do you have? Fluid intake It's no surprise that too many drinks -- whether water, milk, or other beverages -- can be a problem for people with incontinence. However, you can't solve incontinence by severely cutting back on fluids. This can lead to dehydration, constipation, and kidney stones, which can actually irritate your bladder and make symptoms worse. It's important to get the right balance, says Rosser, who recommends about two liters of fluid a day, which is eight 8-ounce glasses. (The right amount depends on your lean body mass.) If you're prone to nighttime incontinence, cut back your fluid intake in the evening. Alcohol If you have incontinence, happy hour can be anything but happy. Alcohol is a diuretic. It causes you to produce more urine, which can contribute to urge incontinence. And it can irritate the bladder, which is a problem for those with overactive bladder. "Limiting the amount of alcohol you consume to one drink a day can help," says John L. Phillips, M.D., program director of urology at New York Medical College, in Valhalla, New York. Coffee and tea Coffee and tea, once your best friends, may now be your worst enemies. They contain caffeine, which like alcohol, is both Continue reading >>
