When you want to lose weight or get healthy, what is the first thing you would normally cut from your diet? If you said fat, you're not alone_  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Jul 23, 2014 5:20 PM UTC  Brown tissue, also known as brown fat Brown tissue, also known as brown fat Getty Images  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Jul 23, 2014 5:20 PM UTC Not all fat is created equal, it seems. When we’re born, we have larger amounts of [brown fat](brown%20fat), so-called because it contains more dark mitochondria, the cell’s energy factories that pull in glucose and use it as fuel to drive cellular functions. Like a hard-working battery, however, brown fat releases heat as it performs its functions, which is helpful to keep newborn infants warm but gets less useful for adults as we’re better able to regulate our body temperature. So as we get older, this brown fat is gradually lost. But in a report published in the journal _Diabetes_, scientists led by Labros Sidossis, professor of internal medicine at University of Texas Medical Branch at Galveston, found for the first time that adults who retained more amounts of brown fat were better able to keep blood sugar under control and burn off fat stores. Previous studies have linked brown fat to better weight control, but these results also hint that the tissue may be important for managing diabetes. **MORE:** [How Now, Brown Fat? Scientists Are Onto a New Way to Lose Weight](http://healthland.time.com/2012/01/26/how-now-brown-fat-scientist-are-onto-a-new-way-to-lose-weight/) The researchers measured the brown fat in a small group of healthy men and also tracked how much energy they used while resting, how well they metabolized glucose, and their sensitivity to insulin, which breaks down and controls blood sugar. Because brown fat tends to be activated under cold temperatures, the scientists also measured these factors after the men sat at room temperature, and again after they sat at 65 degrees to 70 degrees F for five to eight hours. The men who had higher amounts of brown fat – about 70g on average – increased their metabolic rate by 15%, meaning they burned more calories when they were exposed to slightly cooler temperatures, compared to the men with little or no brown fat. That alone, says Sidossis, contributed to burning 300 more calories for these men. Those with higher brown fat were also able to break down more sugar, leading to less of it in their blood, something that hasn’t been shown before in human studies. If the subjects sat in the cooler room for 24 hours, the researchers found, that would lead to a reduction of 25g of sugar in the blood thanks to their brown fat alone. “That’s significant because if you consider people who have diabetes, they only have about 2g to 3g more sugar in the blood,” says Sidossis. **MORE:** [Study: Scientists Find a Way to Trigger Fat-Burning Fat](http://content.time.com/time/health/article/0,8599,1987987,00.html) Interest in brown fat has exploded in recent years, and investigators found that [adults retain more brown fat](http://content.time.com/time/specials/packages/article/0,28804,1945379%5F1944376%5F1944410,00.html) than previously thought, on either side of the base of the neck. Activating this fat store has become a popular area of research; so far, cold temperatures are the only reliable way to stimulate it, but others are exploring ways to [transform white fat into brown fat](http://content.time.com/time/health/article/0,8599,1987987,00.html). As of yet, experts haven’t found a reliable way to turn brown fat on or off in a reliable and metabolically useful way. Genetics may determine how much brown fat people are born with, but if early research is validated, it may also be possible to modify that amount, either with drugs or by transforming white fat. **MORE:** [Turn Down the Thermostat, Drop a Few Pounds?](http://healthland.time.com/2011/01/26/turn-down-the-thermostat-drop-a-few-pounds/) If the results of the current study are confirmed, the need to do so might become more urgent. “Our data suggest that brown fat may function as both anti-obesity and anti-diabetic tissue in humans,” says Sidossis. “And that makes it a therapeutic target in the battle against obesity and chronic disease. Anything that helps in this area, we need to pursue and make sure that if there is potential there, we exploit it.” ## Transcript [ MUSIC ] There's something we all enjoy about staying for dinner. You ever thought why? What was on your dinner table when you were younger? Chances are it had a lot to do with, what your doctor was telling you is healthy. Building a strong healthy body is like building a strong, beautiful building. If the foundation is weak, the whole building will be weak. It takes five fingers to point the way to healthful eating habits. Well, here we go. For years, the government published dietary guidelines. Meant to keep Americans healthy. There's a great deal to learn. Tell me what you eat, and I'll tell you what you are. The body needs certain substances to live and grow. And remember, your body isn't just like an automobile. For years, the key measures of those guidelines were the same, cut fat from your diet. The committee's original report urged Americans to reduce their risk of heart attack. By reducing their intake of cholesterol down to the equivalent of about one egg a day. And those guidelines had an effect. From 1977 to 2012, per capita consumption of eggs fell by 9 %, beef by 37 %, whole milk by 72 %. Calories from saturated fat fell, while calories from supposedly safe carbohydrates increased. As one expert put it, it was a vast nutritional experiment. With nearly a million American's a year dropping dead from heart disease in the mid 80s, we had to try something. Nearly four decades later results are in. The experiment was a failure. Americans are sicker than they've ever been before. The prevalence of diabetes has gone up 157 % from 1980 to 2011. Nearly one in ten Americans now has the disease. Causing the public health system $ 245 billion a year. Heart disease is still the number one killer in the country. Americans are as obese as ever. So, what went wrong? Good old granola. Great for taste but loaded with fat. It doesn't take much of imagine a leap to assume that fat would make us fat, clog our arteries and raise the risk of heart disease. It turns out that saturated fat is a lot more complicated than we think. Carbohydrates and fats are nutrients. Like man, you need nutrients to live and grow. [ MUSIC ] Firstly, there are two kinds of cholesterol. LDL which is linked to heart disease and HDL which can be protective. Fats that course through the blood are known as triglycerides and high levels of those are linked to heart disease. Saturated fat raises LDL cholesterol but also raises HDL. Moving LDL buildup on arterial walls. So raising both, makes saturated fat a cardio wash. One key piece of information is that LDL seems to come in two forms. Large and fluffy, small and dense. Those smaller particles are linked to heart disease, while the larger ones are mostly benign. Saturated fat increases the number of large particles. The opposite happens with carbs. I don't get it. Researchers have long since discovered the kind of fats found in olives and in fish like salmon. Are actually heart protective. Now it turns out the fats found in meat and dairy, aren't as bad as we feared before. So that means by focusing so much on fats. We may actually have been making ourselves sicker. So, she brings up the subject of reduced- fat cheese. It's a fat- free [ UNKNOWN ]. Fat- free, cholesterol free. Low- fat granola. Reduced- fat Kettle chips. Reduced- fat Chips Ahoy. Lowfat cottage cheese. Non- fat yogurt is the perfect example. The thinking for consumers was simple. Fat was dangerous. This product had no fat. Therefore, it must be healthy. It's non- fat, which means less calories. [ MUSIC ] But amid the confusion about fat, we end up replacing it in our diets with sugars and carbohydrates, which meant our calorie intake was actually going up. When carbs and things like corn and white bread are ingested into your body, their converted into sugars. Those sugars convert to insulin cuz it's fat cells go into storage overdrive, leading to weight gain. Since fewer calories are then left to fill the body, you begin to feel hungry it means our metabolism begins to slow down in effort to save energy, we eat more and we gain more weight, never quite feeling full. As this process repeats, our cells become more resistant to insulin, which causes us to gain more weight, which increases insulin resistance in a vicious circle. Cut calories, and people just get hungrier. Obesity, diabetes, high triglycerides and low HDL cholesterol can all follow. Study after study has found it's very difficult to lose weight on a very low- fat diet. Possibly because fat and meat can produce a sense of satiety, that's hard to achieve with carbs, making it easier to simply stop eating. But it isn't just the increase in carbs that affects us. These processed, low saturated fat alternatives, come loaded with sugars, salt, preservatives, and even some unhealthy fats. So what's the real alternative? As one extra puts it, the cold hard truth about diet is that the only way to eat well, is to eat well. You'll be happier and you'll be healthier, if you focus on real whole foods, whether they have fat or not. Got it. And thanks, we'll never forget what we've learned. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3024555/diabetes-risk-linked-to-color-of-fat/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3024555/diabetes-risk-linked-to-color-of-fat/"},"headline":"Having The Right Kind of Fat Can Protect Against Diabetes, Study Says","datePublished":"2014-07-23T17:20:31.000Z","dateModified":"2026-08-04T08:01:01.551Z","description":"People with more \"brown fat\" were better able to keep blood sugar under control and burn off fat stores","url":"https://time.com/3024555/diabetes-risk-linked-to-color-of-fat/","keywords":["diabetes","type 2 diabetes"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/bltae1da69f604efc68/69869cd135ba6f0596c031e4/brown-fat.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Alice Park","jobTitle":"Senior Correspondent","url":"https://time.com/author/alice-park/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/bltae1da69f604efc68/69869cd135ba6f0596c031e4/brown-fat.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Brown tissue, also known as brown fat","caption":"Brown tissue, also known as brown fat","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/diabetes/","name":"diabetes"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3024555/diabetes-risk-linked-to-color-of-fat/","name":"Having The Right Kind of Fat Can Protect Against Diabetes, Study Says"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"The Truth About Fat","description":"When you want to lose weight or get healthy, what is the first thing you would normally cut from your diet?
