Why do you sometimes feel sick when you eat healthy?

So how come you Complete Body aches and your stomach closes?

Any time you change your diet, you may feel a little different for a while.

Here’s what happens to your body when you eat healthy food (and why you shouldn’t give up new habits)!

Why your diet can make you feel sick

It is very common to feel a little sick after adopting a healthy lifestyle. But, if you have any doubts, contact your doctor to stay safe.

If you have recently made a strong or sudden switch, you may not feel your best right away. The reason is here.

1. You are not hydrated.

Some diets, especially low carb diets, can cause your body to lose excess water.

Even if you continue to drink your normal amount of water, you will find yourself mildly dehydrated, which can cause dizziness, rapid heartbeat and rapid breathing.

A good indicator of your hydration level is the color of your urine. Light yellow, good. Dark yellow urine is a clear sign that you need to drink water, stat.

2. Your diet is very extreme.

Converting from a standard American diet to a calorie-restricted or strict diet (think: keto or vegan) to a diet can also be a shock to the body.

“When you take out all the grains, you also lose fiber,” says Money. “Complications like constipation can become a real problem. No matter what diet you’re on, you need plenty of fiber to keep your digestion running.”

If you have skipped meat or other animal products, make sure you are replacing them with healthy whole foods such as lean protein and healthy fats.

3. Your diet is missing essential nutrients.

Excluding whole segments of food like nightshade or legume (unless there is a medical reason to do so) can also eliminate essential nutrients from your diet.

“When you exclude a food department altogether, you also exclude the nutrients that will provide food,” Tucker said. “If you omit a section of food, look out for the main source of nutrients from other sources.

At the same time, if you eat a ton of bacon and avocado but do not touch any veggies, your body is telling you that you are malnourished. ”

4. Your diet is very low in calories.

Your brain and body need an uninterrupted supply of calories to function normally. You will not feel your best if you do not fill your plate enough to get your body all day.

In most diets, “carbs fuel your brain,” says Money. “In a low-carb diet like the ketogenic diet, fat fuels your brain.”

Either way, he adds, you have to eat Enough Food.

“Excessive calorie restriction causes your body to run out of short-term fuels in the form of fats or carbohydrates,” Tucker explains. “It alone can make you feel sick.”

What happens to your body when you eat healthy food?

When you move into a healthier lifestyle and promise clean food and regular exercise, your body can experience much more than just losing weight. Your diet can affect your brain chemistry, your gut microbiome and even your hormone production.

Here’s what happens when you clean your food and how it affects different parts of your body.


Some common digestive symptoms you may experience are:

  • Slow digestion (or occasional constipation, due to low fiber diet or not drinking enough fluids)
  • More travel to the bathroom (due to fiber intake)
  • Stomach cramps (Thanks again, Fiber!)
  • Feeling sick

Barbie Tucker, RD, LD, M.Ed, says your gut microbiome can change within a few days of changing your eating habits, so you can feel the effects of that change, “especially if you eat a lot of old processed foods.” Registered dietitian who practices in the Atlanta area.

And, if you go on a ketogenic or other low-carb diet, your body may slow down due to a lack of complex carbohydrates and thus fiber.

“We’re supposed to get 25 to 30 grams of fiber every day,” Tucker said. “If you find that you are unable to use the restroom, this may be an indicator that your new diet lacks adequate fiber.”

And conversely, your body may become accustomed to digesting large amounts of sugar and common carbohydrates, and is now being told to work harder to have more fiber.

“Most of the time, lack of fiber or insufficient hydration is blamed when digestive problems occur,” Taka said. “Take stock of how much water you drink regularly and consider whether you include enough fiber in each meal.”

Brain health

In a mission to cut out added sugars? You may feel:

  • Headache
  • Feeling sick
  • Dizziness

A study conducted on rats found that while reducing added sugar, brain dopamine sugar takes time to adapt to regular hits.

A human study suggests that prolonged sugar intake (from sweet foods or drinks) has adverse effects on long-term mental health. It also suggests that eating less sugar may be associated with better mental health.

Symptoms of sugar detox are normal and usually subside within a week.

“If your brain is accustomed to a constant supply of sugar through sugary drinks and sugary foods, not to mention the hidden sugars in products like bread and processed foods – a sudden suspension of sugar supply may make you feel less than your best,” Tucker said.

Mood and energy levels

With diet and mood, it is important to know that most serotonin receptors are located in the gut. The intestines and the brain communicate through the vagus nerve and this communication highway demonstrates the importance of food quality for your daily mood.

A 2019 study suggests that eating a healthy Mediterranean-style diet may help protect against mood disorders.

“Your brain consumes a lot of energy,” Tucker explains. “It lives on carbohydrates. Our bodies need them.”

It’s normal if you feel terrible at first when you cut carbohydrates and increase other macros, he says. It’s about how we respond to changes in our eating habits. When we change our diet, our bodies need time to process that change. “

The first few days of healthy eating can leave your body for loop. Some low-carb diets can cause fatigue and muscle pain for up to two weeks. These changes may be attributed to changes in your fuel source.

How good it feels

Before you make any major changes to your diet, be sure to talk to a qualified healthcare provider, such as a registered dietitian or your doctor. The symptoms you are experiencing are your body’s way of attracting attention.

Tucker really advises tuning and listening. Consider whether your changes are sustainable and helpful or too drastic.

Whenever a lifestyle or diet “becomes so difficult that you become stingy to follow it, you go back to the way you used to eat,” he says.
