Fasting Is A Quick Way To Get Lean

Published

on

Intermittent fasting has shown the most promise for boosting metabolism and burning fat, according to a new study published in the journal Cell Research. Researchers put mice on a 16-week intermittent fasting program. The mice ate normally for two days, and then went one whole day without food. Meanwhile, a control group of mice ate the same amount of calories overall, just spread evenly across three days.

After four months, the fasted mice tended to have lower bodyweights than the control-group mice. They also had less white fat and more brown fat, which is used for energy and body heat, and their insulin and glucose levels were more constant.

And that’s not all, says Courtney Peterson, Ph.D., an assistant professor in the department of nutrition sciences at the University of Alabama at Birmingham. “Studies suggest you keep more muscle and lose more fat than on other diets, even if you lose the same number of pounds.” That’s because after about 12 hours of fasting, you run out of stored energy from carbs and start burning stored fat.

There are several different intermittent fasting methods. Three popular ones are:

  1. The 16/8 Method: Skip breakfast every day and eat during an 8-hour feeding window, such as from 12 noon to 8 pm.
  2. Eat-Stop-Eat: Do one or two 24-hour fasts each week, for example by not eating from dinner one day until dinner the next day.
  3. The 5:2 Diet: Only eat 500-600 calories on two days of the week, but eat normally the other 5 days.

The new fasting is not about deprivation, but about divvying up your calories differently than the three-square-meals-plus-snacks pattern—which some scientists say is a mismatch with the way we evolved to eat, when food was sporadic

Alvin Kamara Decides That Weights Are Not Enough In His Workout

Published

on

Saints running back and NFL Rookie of The Year Alvin Kamara is getting ready for next season.

Kamara decided to put the entire weight rack on his shoulders, along with four giant plates, and then he walked 20 yards with them.

As if that’s not difficult enough, Kamara also decided to pull a Jeep behind him during his workout, which probably burned roughly 90,000 calories.

If you want to rush for over 1500 yards maybe you should find a Jeep.

What’s Holding You Back From Being Ripped

Published

on

Do you want to be a ripped guy with abs for all seasons? The answer is a matter of priorities and discipline.

Think about it: Are you willing to cook your own food instead of eating premade meals or buying takeout? Count your macros and measure your food portions? Eat salad while the rest of your buddies are eating pizza? Give up even foods you didn’t think were especially bad for you, such as bread, cheese, and milk? Commit yourself to getting more sleep than a normal guy?

If you answered yes to all those questions, you may have the dedication needed to get ripped. If not, no worries—you can still be strong, healthy, and lean, a guy who’s always energized and resistant to disease but won’t appear in a firemen’s calendar anytime soon. And no one says you have to.

But if ripped is your goal, we’ve got the goods. You’ll achieve a lean physique faster with this approach than with any other you’ve tried so far.

Determine how those calories break down into grams of protein, carbs, and fat. Because getting ripped demands resistance training and lifters need more protein than regular folks to repair muscle, set your daily protein intake at 1g per pound of bodyweight. You need carbs to provide energy for workouts and recover from training, so again, 1g per pound is good. As for fat, keep it low to keep calories under control (1g of fat has more than twice the calories of a gram of protein or carbs), but not so low that you negatively impact hormones like testosterone: Start with 0.4g per pound per day.

So for our 250-lb man who wants to be 180, his macros are 180g protein, 180g carbs, and 72g fat.

Do Fitness Trackers Really Work?

Published

on

This article was written by K. ALEISHA FETTERS and was originally published on Details.com.

THE QUESTION: I’M constantly looking at my fitness tracker. But how much can I really rely on what it’s telling me?

The expert: Ray Browning, Ph.D., director of the Physical Activity Energetics/Mechanics Lab at Colorado State University

The answer: It depends what, exactly, you’re tracking and which brand you’re wearing.

Why? These fitness devices track everything—from calories burned to steps taken—with their built-in accelerometers. And as the name suggests, they only detect acceleration (changes in motion), not exertion. They don’t have any idea if your arm is wielding a candy bar or a 50-pound dumbbell.

That’s why, as you may or may not have noticed, your tracker gives you little to no credit for some of your workouts. A lot of strength training exercises—not to mention biking—all read like you’re just chilling out on the couch, Browning says. Remember: If your tracker is not bouncing around, it’s not counting your exercise.

In one recent study published in Medicine & Science in Sports & Exercise, trackers’ calorie expenditure (one subset of the genre) was found to be between 10 and 15 percent off, on average, which isn’t so bad. Researchers asked 30 men and 30 women to complete a 69-minute workout that included 13 different activities—from writing at a computer and playing Wii tennis to running and shooting hoops. They then compared the readings from eight fitness trackers against those from portable (and far more accurate) metabolic analyzers.

The BodyMedia FIT, Fitbit Zip, and Fitbit One, were the most accurate (with 9.3, 10.1, and 10.4 error ratings, respectively), while the Jawbone Up, Actigraph, Directlife, Nike Fuel Band, and Basis Band, brought up the rear (with 12.2, 12.6, 12.8, 13.0, 23.5 percent error ratings, respectively).

But if you put too much faith in even the most accurate trackers—basing your calorie intake on how many calories your device says you’re burning—you could end up gaining, not losing weight, Browning says. For instance, if your fitness tracker says you’ve burned 3,000 calories today, you may have actually only burned 2,500.

The smartphone apps for some of these fitness trackers will let you manually enter exercises to get a more accurate calorie-burn total, but even if your tracker knows your height, weight, age, and gender, the calorie-estimate could be off, of course. (the accuracy of cardio machine calorie-counters is another matter.)

There is a silver lining, though: “These fitness trackers may not be accurate in counting calories, but their results are repeatable,” says Browning. If you do the exact same thing two days in a row, you can expect the same tallies from your tracker. That means you can easily use them to track your progress. Have you burned more calories today than yesterday? Taken more steps? You can trust that info.

And progress, in the end, is what will make you fitter and faster.
