LEAN staat voor een managementfilosofie:
Lean manufacturing of lean production is een managementfilosofie die erop gericht is om maximale waarde voor de klant te realiseren met zo min mogelijk verspillingen (無駄, Muda). Door de 'slanke productie' gaan de kosten omlaag, wat leidt tot een verbetering van het bedrijfsresultaat. De methode is afkomstig van de Japanse autofabrikant Toyota waar men zich baseerde op de gedachten van Henry Ford en de scientific management school. Door de successen van Toyota kreeg deze filosofie meer bekendheid en navolgers. Begin eenentwintigste eeuw wordt het in veel bedrijven toegepast.
De lean-principes kregen voor het eerst vorm in de Japanse industrie. De term lean is het eerst gebruikt door John Krafcik in zijn in 1988 uitgekomen artikel getiteld Triumph of the Lean Production System, gebaseerd op bevindingen opgedaan gedurende onderzoek voor zijn masterscriptie op de MIT Sloan School of Management. Krafcik was een quality engineer in de NUMMI joint venture van Toyota en GM in California, voordat hij naar MIT kwam voor zijn MBA studie. Krafcik's research is voortgezet door het International Motor Vehicle Program (IMVP) van MIT, dat ook de internationale best-seller schreef door Jim Womack, Daniel Jones, and Daniel Roos, genaamd The Machine That Changed the World.Voor velen is Lean manufacturing een aantal gereedschappen of technieken waarmee men verspilling (muda) kan vinden en verminderen. Door de vermindering van verspilling verbetert de kwaliteit en nemen de productietijd en kosten af. De belangrijkste hulpmiddelen zijn: Value stream mapping, Kanban, 5S, poka-yoke (error-proofing), SMED, Total Productive Maintenance, mixed model processing, Rank Order Clustering, scheduling, herontwerpen van werkplekken, multi-process handling en statistische procescontrole.
Er is een tweede aanpak van lean Manufacturing, gebruikt en geadviseerd door Toyota, genaamd The Toyota Way, waarbij de focus ligt op het verbeteren van de "flow" of de soepele manier waarbij de producten door het productieproces stromen, waarbij continue mura ("variatie") verminderd wordt. Dit legt de focus niet op het reduceren van de verspilling. De technieken om de flow, die continue doorloopsnelheid verbeteren zijn onder andere pullproductie (met behulp van 'kanban) en de heijunka box.
Het verschil tussen deze twee filosofiën is niet het doel zelf, maar meer hoe men er wil komen. Door te focussen op een soepele stroom komen de knelpunten naar boven, waardoor als uitvloeisel ook de verspilling wordt bestreden. Het voordeel van deze tweede aanpak is dat er eigenlijk van nature al het systeem als geheel wordt bekeken, terwijl de focus op verspilling misschien zaken laat liggen (http://nl.wikipedia.org/wiki/Lean_manufacturing).
Bier heeft de naam dat het zorgt voor een dikke vette bierbuik.
Do you drink a lot of beer? Notice how your belly is getting bigger? Or are you getting fatter due to eating too much? Here is the explanation you were looking for. Alcohol in your drink is actually a chemical called, ethanol, which has an alcohol group attached to it (-OH) in chemistry terms.
http://questionfiller.blogspot.nl/2011/05/what-causes-weight-gain-and-beer-belly.html
In order to digest something, our body needs to break it down into smaller fragments (think of it as our body's way of chewing the food up internally once the food is swallowed) so when we drink our alcoholic beverages, our body must decompose it (http://questionfiller.blogspot.nl/2011/05/what-causes-weight-gain-and-beer-belly.html).
Decomposition of alcohol occurs in the liver due to the presence of an enzyme (think of it as a small machine in your body which helps with digestion) called, alcohol-dehydrogenase.
When the enzyme breaks down 17 grams of alcohol in your liver:
- It releases 460,000 J of energy (100 grams of steak consists of about 648,000 J of energy).
- 1 gram of fat consists of 37,700 J of energy
- so taking 17 grams of alcohol is equal to producing roughly 12.2 grams of fat!

How beer makes you fat:
1. You take a swig of beer.
2. Within seconds, the beverage passes through your oesophagus and into your stomach.
3. 20% of the alcohol is absorbed immediately into your bloodstream from your stomach; the rest passes into your intestines, and is absorbed from there.
4. The alcohol travels through your blood to your liver, where it's broken down. During this process, waste products called acetate and acetaldehyde are created. The stronger the beer, the more acetate and acetaldehyde.
5. Your brain immediately prioritises dealing with the acetate and acetaldehyde, signalling your body to stop burning fat. At the same time, it actually starts producing fat from another waste product of alcohol, acetyl CoA.
6. Your body can effectively process only 15-30ml of alcohol per hour.
So the more you drink, the longer your body is inhibited from burning fat, and the more fat builds up from the excess acetyl CoA. (A pint of standard 4% beer contains 22.7ml of alcohol. That means that on a six-pint night, you imbibe 136ml of alcohol – essentially, halting your fat burn for up to nine hours.) (www.menshealth.co.uk/lose-weight/fast-tips/how-beer-makes-you-fat-323945)
Now if you eat normally, (which means providing your body with 2000 calories of energy per day) then drink, you might produce excess fat due to the excess energy the alcohol provides you with. Further more, beer makes our blood sugar level drop causing our body's metabolism to slow down therefore we burn less calories than we usually do so it makes the production of fat much easier. Over time, if this habit continues, you will grow side-ways and front-ways instead of the preferable up-wards!! (http://questionfiller.blogspot.nl/2011/05/what-causes-weight-gain-and-beer-belly.html)
Have years of too many beers morphed your six-pack abs into a keg? If you have a "beer belly," you are not alone. It seems beer drinkers across the globe have a tendency to grow bellies, especially as they get older, and especially if they are men. But is it really beer that causes a "beer belly"? Not all beer drinkers have them -- some teetotalers sport large ones. So what really causes men, and some women, to develop the infamous paunch? (www.webmd.com/diet/features/the-truth-about-beer-and-your-belly)
This is the apple shaped body of a human being. Though the real reason behind this is not yet well known, research indicates that it is caused by consuming large amounts of alcohol at one go, not over a period of time. For example, it is more likely that a person will get his apple shaped nature if he drinks a whole bottle of whiskey at one go than to spread it throughout the day. It is also said that beer belly's are not purely caused by alcoholic beverages but rather its the persons diet and life style.
Beer belly's can happen in people who drink wine or liquor NOT only beer.
According to research, if you drink at least 80 grams at one time, everyday for 1 month then your waistline increases by 0.5 inch (1.25 cm).
Your waistline is not related to how much alcohol you consume per day but it is how much you consume at one time. An average adult drinker has about 10% of their total daily energy intake from their alcoholic drinks. Posted by Quiller
Reputable research has suggested that it is the quality and quantity of food eaten after the beer consumption which results in the beer belly. Beer does not contain fat, but it has bulk, which stretches the stomach lining, and it contains sugar. John Cammish, London
It’s not necessarily beer but too many calories that can turn your trim waistline into a belly that protrudes over your pants. Any kind of calories -- whether from alcohol, sugary beverages, or oversized portions of food -- can increase belly fat. However, alcohol does seem to have a particular association with fat in the midsection (www.webmd.com/diet/features/the-truth-about-beer-and-your-belly).
"In general, alcohol intake is associated with bigger waists, because when you drink alcohol, the liver burns alcohol instead of fat," says Michael Jensen, MD, an endocrine expert and obesity researcher with the Mayo Clinic in Rochester, Minn (www.webmd.com/diet/features/the-truth-about-beer-and-your-belly).
Beer also gets the blame because alcohol calories are so easy to overdo. A typical beer has 150 calories – and if you down several in one sitting, you can end up with serious calorie overload. And don’t forget calories from the foods you wash down with those beers. Alcohol can increase your appetite. Further, when you're drinking beer at a bar or party, the food on hand is often fattening fare like pizza, wings, and other fried foods (www.webmd.com/diet/features/the-truth-about-beer-and-your-belly).
Beer alone would not make you fat unless you drank gallons of it. Three pints of beer are roughly the same calories as one bar of Chocolate! Jim McDonnell, Chorley Lancs
What’s Wrong With a Beer Belly?
Belly fat in the midsection does more than reduce your chances of winning the swimsuit competition. It's linked to a variety of health problems, from type 2 diabetes to high blood pressure and cardiovascular disease (www.webmd.com/diet/features/the-truth-about-beer-and-your-belly).
“How come I can diet, and diet, but I just can’t lose that fat around my belly!?” This is a question that my trainers and I have heard all too often. All calories are not created equal. For every gram of carbs and protein there are 4 calories, fat has 9, and alcohol has 7.5. The kicker is that your body hates to burn fat (as we all know), so it chooses carbs first as the body’s main source for fuel. Alcohol has to be turned into fat before it can be burned off! So, if you eat well, but drink too much, the alcohol you consume has to convert to fat before it ever gets burned off. Now, most people never tap into their fat stores often enough to make a dent to that newly converted fat storage. Even though your calories might not be that high, the excess alcohol will convert to fat, leading to additional abdominal fat….”the beer belly” (www.dextertrainingconcepts.com/you-booze-you-lose-and-gainfat-that-is/).
A wise man once said, “Drinking beer doesn’t make you fat; it makes you lean… against bars, tables, chairs and poles.” Turns out the guy was half right. The college lifestyle of all-you-can eat dining halls, all night study sessions and partying Thursday to Sunday can quickly catch up to your waist line (http://anacissastipsntricks.blogspot.nl/2011/12/getting-rid-of-that-ridiculous-beer.html). De tips die volgen zijn geen bier meer drinken, minder bier gaan drinken of light bier gaan drinken. Drie opties waar je dus niet veel mee kan.
Lean Machine, as described on their website, is “a sport recovery, low calorie, FIT BEER.” In the long line off low calorie beers, Lean Machine has achieved the lowest count, but can you call it beer — with an ABV of 0.5%, seven vitamins, and seven grams of protein? And being called ”Lager Ale” makes no sense. Obviously a Lager is not an Ale, and a sport recovery drink is not a beer (www.beerandbrewing.com/lean-machine-beer-abomination/).
The idea of beer that makes you fitter may sound like a boozehound's daydream, but thanks to a Canadian drinks brand it might just have become a reality. Lean Machine by Vampt claims to be the world's first 'recovery ale'. Developed by a team of intrepid food scientists, the drink contains a rejuvenating cocktail of electrolytes, anti-oxidants and vitamins, plus 2.5g of carbs and 7g of protein - all of which are required by your body after exercise to replenish its cells. And it weighs in at only 77 calories per serving (half the normal amount for beer). In short, Lean Machine could get your body back on track just like a Lucozade or Powerade.
“All beer contains proteins and nutrients that help the body recover, but a lot of that is taken out in the brewing process,” said Vampt founder Ian Troews. “We just thought that maybe we could do something that would support a drinker, make it still socially fun, and help them accomplish what needs to be accomplished after an aggressive workout.”
Though the formulation of a ‘fit beer’ may sound like an oxymoron, recent research has suggested that beer's dehydrating effect can be defeated (www.telegraph.co.uk/men/active/10709175/Introducing-Lean-Machine-beer-thats-fit-for-an-athlete.html, www.newser.com/story/183359/beer-the-new-sports-drink.html).
In a study published December 2012 in the International Journal of Sports Nutrition and Exercise Metabolism, he and his colleagues found that beer's dehydrating effect can be weakened by changing its electrolyte content — a good first step into turning ale into a sports beverage.
By lowering the level of alcohol by volume to 2.3 percent and adding salt, they found that the manipulated beer actually hydrated their sample of athletes better than traditional ale.
Plus, he adds, since beer is plant based — the key ingredients, aside from water, are barley, hops and yeast — it contains a whole range of naturally occurring nutrients that manufactured sports drinks don't have.
"A properly formulated beer beverage is likely to do you no more harm than you are likely to get from a sports drink," Desbrow says. "In fact, it probably is likely to do you more good, because it's got a lot of these sort of natural compounds, like polyphenols, that are actually good for your health."
He's talking about compounds found in plants that are believed to have anti-inflammatory and antioxidative effects. A 2011 study in Germany suggested that polyphenols in beer may be especially useful for those who go through prolonged strenuous exercise, which tends to lower the body's immune function.
In the study, those who were given nonalcoholic beer every day for three weeks before and two weeks after a marathon reported fewer incidences of upper respiratory tract infections and were up to three times less susceptible to the common cold (www.npr.org/blogs/thesalt/2014/03/05/285693136/beer-as-a-post-workout-recovery-drink-not-as-crazy-as-it-sounds).
