Lose Weight Fast Comments Off on Everything You Think You Know About Carbs Is Wrong – Yahoo Lifestyle

Its easy to write off carbohydrates as the enemy. After all, many of us grew up hearing the praises of Atkins, and you probably know at least one person who wont shut up about how going keto gave them the body of their dreams. What both diets have in common? Cutting carbs.

But dont fall for it forgoing carbs is not the golden path to weight loss, and certainly not the answer to feeling less bleh after indulging in some of your favorite foods. In fact, you're less likely to gain weight and even develop some serious diseases if you eat more carbs, says nutritionist Lisa Young, Ph.D., R.D.N., adjunct professor of nutrition at New York University. Here, experts explain what you really need to know about including carbs in a healthy diet.

First things first: Even though most of us automatically associate carbs with grains, they are just one type of carbohydrate as are fruits, vegetables, sugars, alcohol, and even some dairy. (A carbohydrate actually just refers to a type of organic compound found in foods that contains two parts hydrogen to one part oxygen.)

You can divide carbs up a few ways, such as sugars, fiber, and starch; but in terms of healthy and unhealthy, there are two categories: whole and refined.

Whole refers to anything that still has its original chemical composition. With, say, a kernel of wheat, it has an endosperm, bran, and germ, the latter two being where all the fiber, vitamins, and minerals are stored. For refined carbs, though, manufacturers strip out the healthy germ and bran and just leave the endosperm center.

Science lesson aside, this distinction is crucial. Processed carbs are rightly vilified. Theyre missing the fiber, which helps you feel full, along with the micronutrients and antioxidants that help protect against diseases, Young explains. They're also crucially helpful for digestion.

A huge study last year in The Lancet found that over the course of 25 years, people who scored 50 to 55% of their diet from carbs were the least likely to die. (For perspective, a low-carb diet caps that intake at roughly 30% and keto somewhere between 5 and 10%.)

Now, there is a limit people who ate either low-carb or high-carb in The Lancet study had a higher mortality risk, so too much is just as bad as too little.

But theres something to be said of the risk of too little, like what chronic Keto-ers consume: A large study earlier this year in European Heart Journal involving some 25,000 people found folks with the lowest carb intake actually had the highest risk of cardiovascular disease, stroke, cancer, and overall mortality. What's more, despite these diseases often being tied to a heavy weight, non-obese people were actually the most at risk for overall mortality.

Why? Because low-carb dieters are cutting carbohydrates and upping their fat and protein, they often eat more animal products and less vegetables and fruit, Young says. That means an increase in saturated fat which is tied to heart disease, and a decrease in antioxidants that help fight disease-causing free radicals.

FWIW, The Lancet study does distinguish that low-carbers who swapped in plant proteins and fats had a lower risk of disease than their counterparts who loaded up on animal products. But moderate carb intake was still tied to the lowest disease risk, and other studies have reported that people on a low-carb diet are more likely to be deficient in certain nutrients like thiamin, folate, vitamin C, calcium, magnesium, and iron.

Avoiding serious illness and even premature death feels like reason enough to include carbohydrates in your diet, but let's address the elephant in the room, which is that most people who cut carbs in the first place are doing so in an effort to lose weight. Pretty much anyone who tries the keto diet raves about how easy it is to drop pounds. And its true that cutting carbs reduces water weight, says Maggie Moon, MS, RD, Los Angeles-based registered dietitian and author of The MIND Diet. But carbohydrates dont make you retain fat.

Keto-style diets may seem effective at reducing body fat for a variety of reasons, she says. But long-term studies dont show keto holds any magical benefits over low-fat diets for maintaining weight loss.

In fact, a recent Stanford study of more than 600 adults found people who followed a healthy, low-fat diet eating about 50% carbs, 30% fat, and 20% protein lost the same amount of weight in three months as folks who ate a healthy, low-carb diet (30% carbs, 45% fat, and 25% protein). Thats probably because they ended up eating about the same number of calories naturally.

The consequences of unhealthy carbs are what give us this false association: A small 2013 study in American Journal of Clinical Nutrition had 12 people eat the same number of calories, but from foods that vary on the glycemic index (a measure of how quickly your blood sugar shoots up).

Researchers found that after people ate foods high on the glycemic index (i.e., white bread, white pasta, and processed carbs), they were hungrier and had more activity in the parts of their brain associated with reward and cravings in the hours after eating, which directly influences what you'll eat at your next meal. When they ate non-processed foods low on the glycemic index, this wasnt a problem.

At the end of the day, gaining weight is still about excess calories in, Young says. And healthy carbs are loaded with fiber, which aids in satiety, helping you feel full and signaling to you when to stop eating so you dont over eat, she explains.

Of course, if weight-loss (or weight maintenance) is your goal, exercise is the other part of the equation. But daily exercise is also directly tied to heart health and lower disease risk and carbohydrates are the bodys preferred source of fuel for said exercise.

Yes, your body can learn how to become fat-adapted and convert fat to fuel as every low-carber argues but its way harder. Even if you become fat-adapted, you cant convert fat to fuel at the same rate you can carbs to fuel, Young explains. For example, athletes who followed a super low-carb, ketogenic diet had less power output during short, high-intensity bursts of exercise, says a 2018 study in the Journal of Sports Medicine and Physical Fitness.

That efficient conversion makes carbs just as important for endurance exercise, Moon adds. An hour into your run or bike when your carb/glycogen stores have been completely depleted, replenishing them can give you more energy to stick with the cardio for longer, far better than the slow-burning fat. And reloading depleted glycogen stores ASAP post-workout will help you recover and perform better for the next workout, she adds.

So, some carbs are better than none but how do you tell which are healthy and which are a sugar trap? If youre worried about navigating this carb-heavy time of year or thinking about reevaluating your diet in the new year, these six guidelines can help keep you on the right track:

1. Dont assign emotional baggage to food. Foods, including carbs, arent morally good or evil theyre just food, Moon says. Take away the emotional load and youre left with science: What will and wont make my body feel good.

2. Steer clear of anything white, unless its a whole vegetable. For the most part, white means refined, Young says. The next step is to read the ingredients, but generally the only good food thats white comes from potatoes, turnips, cauliflower, or tofu and its usually pretty easy to tell if what youre holding is the blank color because of that or because its been uber-processed.

3. Eat closer to nature. Youve heard this before, but its honestly the best rule in differentiating healthy carbs from unhealthy ones, Moon says. Opting for a baked sweet potato instead of sweet potato chips or an apple over apple juice not only guarantees youre choosing healthy carbohydrates instead of the refined version, but feeling energized and fueled with the cleaner variety can help rewrite your associations that carbs are bad.

4. Only eat grains that say whole. Packaging that says multi-grain or just wheat are taking you for a sucker. If it doesnt say whole before a grain on the nutrition label, its been processed and is missing that optimal nutrients and fiber, Young says.

5. Fill one-quarter of your plate with whole grains or starchy vegetables. Remember, eating too many carbs regularly ups your risk of major diseases just as much as too few carbs. Don't miss out on the goodness, but try not to have too much of a good thing, either.

6. Eat as many vegetables and fruit as you want. Produce is super low in calories and incredibly high in fiber to help you avoid overeating, making it a great addition to any meal. Unless youre following a specific macro plan, the carbs in fruits and vegetables wont topple your plate portions and should actually comprise half of every meal, Young says. (That last quarter should be protein.)
