It is a common rookie mistake, but plenty of diet-and-exercise veterans make it, too: With an act of will, you muster you to ultimately a fitness center or even the track, and you gut the right path with an arduous workout. Whenever you slimming plus natural capsule sit down to dinner or go to the break room later that day, you say to yourself, "By God, I've earned this (sugary soda, yummy snack, second helping, dessert, second glass of vino). I worked hard today!"

A week or so later, you're sitting on the size wondering what went down.

Answer: You forgot to possess fun.

New research delves into one of the great mysteries of diet, exercise and weight loss: why, when you have started a grueling exercise regimen in a bid to shape up, it is common to gain, not slim down. Sure, there is the old reassurance that muscles weigh greater than fat. But when the load gain comes before any evidence that we've changed our body composition significantly, I think we all know we're kidding ourselves.

"Framing" - or the approach we take to consider - the expertise of exercise matters, a trio of researchers at Cornell University's food psychology lab found. Specifically, they found, it influences not only what we choose to eat after the experience, but exactly how much of it.

When we consider the physical activity we participate in as fun, or at least incidental to fun, we make better food choices. Whenever we frame physical activity as exercise, we're more likely to choose rewarding foods and also to eat more of them, the study found.

The research, published Thursday within the journal Marketing Letters, was ingeniously simple. College administrative staff members were advised to put on comfortable shoes and were promised a free lunch after they completed their task. Half the topics were handed a map, told the purpose of the study was to exercise, and sent on a 30-minute, 1-mile course with occasional stops to assess their level of fatigue.

Another half received exactly the same walking map but handed an MP3 player and told the reason for the study was to measure the clarity of the music at six different stopping points on the way.

Afterward, researchers offered their 56 subjects a lunch of pasta and meat sauce, peas and a selection of either a sugary soft drink or water and applesauce or chocolate pudding. Researchers distracted their subjects not only so they wouldn't discuss their walking experiences together, but so they could measure how much they served themselves and record what choices they made.

A second experiment used exactly the same walking course but set one group on which was referred to as a sightseeing walk as the other continued what it was told was a workout course. Afterward, researchers offered the 46 subjects the chance to help themselves to M&Ms and surreptitiously weighed the bags that subjects poured for themselves before sending them enroute.

Compared with the walkers distracted by pleasant music, the exercisers were more prone to choose sugary soda over water. Even though the exercisers were no more or less likely to select the chocolate pudding, they served themselves more of it, typically, than did the subjects who thought they'd taken an enjoyable walk.

Interestingly, the two groups consumed roughly exactly the same quantity of calories' worth of pasta, sauce and peas. That, said the researchers, shows that the workhorse subjects were rewarding themselves by choosing and eating more from the foods and beverages that are tasty treats compared to what they were simply boosting their calorie intake.

In contrast to subjects who ambled along taking in the campus' attractions, those who perceived their walk as exercise served themselves larger servings of M&Ms when completed from the walk.

Finally, the researchers took benefit of a real footrace and asked 231 runners who'd run between 5 and 10 kilometers to complete a brief survey that assessed how much fun they had had. They offered the runner a choice of a chocolate bar or a cereal bar.

Sure enough, irrespective of runners' hunger levels, their body mass index or even the distance they had run, people who indicated they'd had more fun running the race were more prone to take a cereal bar. The sweets were more often the option of people who viewed the race more like a test or a workout than the usual pleasant challenge.

The upshot is simple, said Brian Wansink, director of the Cornell Food and Brand Lab: If you feel of the physical activity as fun, you're less likely to want to treat yourself than if you see your exercise routine being an exhausting chore. That may involve several mind games, he noted, but the reward is you won't negate the jimpness beauty fat loss capsule benefits of your workout with poor diet.

"Do anything you can to create your workout fun. Play music, see a video or simply be grateful that you're working out rather than working in the office," said Wansink. "Anything which brings a smile is likely to get you to consume less food."
