What happens if i eat junk food and exercise

You'll end up exhausting yourself, feeling lousy and possibly becoming even hungrier due to over-exercising and eating poorly. You might also end up becoming dependent on exercise to burn off the extra kilojoules you eat from junk food. I do have some good news, though. It is possible to have a healthy lifestyle, choose nourishing foods and still have a few extras, treats or the occasional junk food on the side, without stacking on unwanted weight. It's all about budgeting your food choices.

If you burn calories boxing, in a HIIT session, or running then treat yourself to a double cheeseburger, then yeah, your fat loss has just become a herculean struggle.

Thinking of your body as a bank where you just cash in and check out calories neglects the fact your hormones matter most for lasting fat loss, Virgin says. Calories are not created equally. The result: It gets stored as fat. Exposure to high levels of these chemicals could lead to reproductive issues, including birth defects. Carb-rich foods lead to blood sugar spikes, and these sudden jumps in blood sugar levels may trigger acne.

Eczema is a skin condition that causes irritated patches of inflamed, itchy skin. Carbs and sugar in fast food and processed food can increase acids in your mouth.

These acids can break down tooth enamel. As tooth enamel disappears , bacteria can take hold, and cavities may develop. Obesity can also lead to complications with bone density and muscle mass.

People who are obese have a greater risk for falling and breaking bones. Today, more than 2 in 3 adults in the United States are considered overweight or obese. More than one-third of children ages 6 to 19 are also considered overweight or obese.

The growth of fast food in America seems to coincide with the growth of obesity in the United States. The number of obese Americans has also more than doubled.

Despite efforts to raise awareness and make Americans smarter consumers, one study found that the amount of calories , fat , and sodium in fast-food meals remains largely unchanged. For optimal health, it's a good idea to choose the foods that contain the most nutrients.

Here are the 11 most nutrient-dense foods on earth. Feeding your body certain foods, such as citrus, turmeric, and ginger, may help keep your immune system strong. Incorporate these foods into your diet…. The Mediterranean diet includes lots of healthy foods like whole grains, fruits, vegetables, seafood, beans, and nuts. This article details all you…. Yet surprisingly, some experts actually argue that fast food can be beneficial to elite athletes — by restoring their depleted energy and glucose stores after a workout.

When you exercise or lift weights, your muscles draw on glycogen stores to provide them with energy to complete the hard work. Typically, by the end of a workout, your glycogen stores will be lower, requiring you to fuel up on healthy carbohydrates or sports drinks with electrolytes. Fast food may seem like the very last option to restore your energy stores after a good workout. But a small study with 11 participants published in the October issue of the International Journal of Sport Nutrition and Exercise Metabolism found that the effects of consuming fast food were similar to that of isoenergetic sport supplements to restore glycogen after working out.

The takeaway from this study; however, isn't that fast food is good for you; rather, it's that sugary products like energy bars or sports drinks may not be any better for you than eating fast food after a workout. In addition, elite athletes are a small fraction of the population who might benefit from consuming fast foods high in sugar or carbohydrates after an intensive, several-hour training session.

For the rest of the average population, however, things are different. If you're sedentary or moderately exercising, about half an hour a day five days a week, junk food likely won't benefit your workouts or recovery at all. This holds true especially for people who are aiming to lose weight. In fact, junk food may drain your energy during exercise rather than refuel it.

An animal study conducted at UCLA found that eating a lot of fast food causes impaired task performance and lack of motivation, rather than the other way around. Rats fed a junk food diet tended to gain weight and take longer to complete tasks, taking plenty of breaks in between, while rats fed a healthier diet remained lean and finished tasks sooner.

The fatigue and lack of energy to exercise you may feel may have more to do with your diet than your own personal motivation. Fast food can also impair your metabolism, according to a study published in January in the journal Health Promotion Perspectives.

The study found that a poor diet was linked to abdominal fat gain, disrupted insulin and glucose homeostasis, systemic inflammation and a higher risk of metabolic syndrome. An impaired metabolism can make it harder to lose weight and can also contribute to low energy.

Refueling your body with healthy, nutritious food post-workout is almost as important as the exercise itself.
