Craving junk food on a diet?  Go for a run: Study finds strenuous exercise makes you less likely to give up

This is probably the last thing you want to do while dieting.

But an intense jog can beat those junk food cravings during a calorie deficit, according to one study.

In an experiment with rodents, scientists found that after a month on a restricted diet, strenuous physical activity reduced cravings for high-fat pellets.

It is known that the hormonal changes that occur when we do strenuous exercise have a short-term appetite suppressant effect.

The researchers said exercise can help resist the cues of eating fatty foods, especially for those who have been dieting for a while and those whose cravings are starting to increase.

Dr. “We’re always looking for that magic pill, and exercise is just around the corner with all these benefits,” said Brown, a neuroscientist at Washington State University who led the research. Said.

A US study in rats found that those who followed a vigorous exercise regimen were better able to resist the siren song from a fat binge.

Obesity is a growing problem in the UK and around a quarter of adults and children in the UK are classified as overweight.

The problem is even greater in America, where about half of adults are considered obese.

HOW IS YOUR BODY MASS INDEX CALCULATED – AND WHAT DOES IT MEAN?

Body mass index (BMI) is a measure of body fat based on your weight relative to your height.

Standard formula:

  • BMI = (weight in kilograms / (height in inches x height in inches)) x 703

Metric formula:

  • BMI = (weight in kilograms / (height in meters x height in meters))

Dimensions:

  • Below 18.5: weak
  • 18.5 – 24.9: Healthy
  • 25 – 29.9: fat
  • 30 or higher: obese

The latest experiment, published in the journal Obesity, aimed to test a phenomenon called ‘craving incubation’.

This theory is that the longer someone is held by someone, the more they want him.

The researchers trained two groups of 14 mice to pull a lever that, when activated, turns on the light and emits a musical tone before dispensing a high-fat food pellet.

After training, the researchers built a baseline for how often rodents would press the lever to pick up a pellet.

They then divided the rats into two groups, one subjected to an intense training regimen and the other group not administered as a control.

Both groups were denied access to leverage and high-fat granules for one month, after which all rodents regained access to leverage.

The scientists found that rats that exercised during the 30-day abstinence period drew significantly less leverage than those that did not participate in the exercise regimen.

Dr. Brown said this shows that exercise reduces rodents’ cravings for fatty foods.

He said the team now aims to test how different levels of exercise affect this type of desire, as well as find out how physical activity produces resistance to this desire in the brain itself.

Dr. Whether food can be addictive in the same way as drugs is still an open question for researchers, Brown noted, and “no one eats broccoli.”

HOW MANY PRACTICES DO YOU NEED?

To stay healthy, adults ages 19 to 64 need to try to be active on a daily basis and:

  • At least 150 minutes of moderate aerobic activity per week, such as cycling or brisk walking
  • Strength exercises targeting all major muscles (legs, hips, back, abs, chest, shoulders and arms) 2 or more days a week

OR:

  • 75 minutes of vigorous aerobic activity each week, such as jogging or a singles tennis match.
  • Strength exercises targeting all major muscles (legs, hips, back, abs, chest, shoulders and arms) 2 or more days a week

OR:

  • A mix of moderate to vigorous aerobic activity each week – for example, 2 x 30 minutes of jogging plus 30 minutes of brisk walking equals 150 minutes of moderate aerobic activity, and
  • Strength exercises targeting all major muscles (legs, hips, back, abs, chest, shoulders and arms) 2 or more days a week

A good rule of thumb is that 1 minute of vigorous activity provides the same health benefits as 2 minutes of moderate activity.

One way to achieve the recommended 150 minutes of weekly exercise is to do 30 minutes, 5 days a week.

All adults should also interrupt long periods of sitting with light activities.
