A frequently added discussion here @30BaD is people experiencing a swollen belly and or abdominal bloating.  

It is normal on this diet to go to bed fat and wake up flat.

However, other symptoms may include generalized bloating, gas in its various forms including burping, belching, flatulence, and flatus, indigestion, sour stomach, abdominal pain, vomiting, constipation, diarrhea, and slowed digestion making it difficult to eat enough calories.  

This list is not all inclusive, but covers some of the common symptoms.  Some of the reasons and causes as well as solutions will be discussed here although not all inclusive.  


Abdominal Bloating Emergencies

It is recommended to call a healthcare provider and seek medical assistance for the following conditions that may accompany abdominal pain and swelling for more than a few days: (1)

  • Blood in the stools or dark, tarry looking stools
  • Diarrhea
  • Heartburn that is getting worse
  • Vomiting
  • Weight loss

Abdominal Pain

The abdomen extends from below the chest to the groin. Some people call it the stomach, but the abdomen contains many other important organs. Pain in the abdomen can come from any one of them. The pain may start somewhere else, such as the chest. Severe pain does not always mean a serious problem. Nor does mild pain mean a problem is not serious.

Call your healthcare provider if mild pain lasts a week or more or if you have pain with other symptoms. Get medical help immediately if:  (2)

  • You have abdominal pain that is sudden and sharp
  • You also have pain in your chest, neck or shoulder
  • You're vomiting blood or have blood in your stool
  • Your abdomen is stiff, hard and tender to touch
  • You can't move your bowels, especially if you're also vomiting

Medical Causes 

A swollen abdomen is when the belly area is bigger than usual. Alternative names include swollen belly, swelling in the abdomen, abdominal distention, and or distended abdomen.  (3)

This problem can be caused by:


Edema means swelling caused by fluid within the body's tissues. It usually occurs in the feet, ankles and legs, but it can involve the entire body. (4)

Causes of edema include:

Eating cooked and processed foods high in salt can cause edema and fluid retention within the abdomen.  


Malnutrition and Calorie Restriction

Malnutrition is the condition that occurs when the body does not get enough nutrients from  inadequate or unbalanced diets, problems with digestion or absorption, and certain medical conditions .  Malnutrition can occur by not eating enough food which could be caused by lack of availability of food, voluntary fasting, restrictive diets, and eating disorders such as anorexia nervosa and bulimia. Starvation is a form of malnutrition.  Malnutrition may develop by lack of a single vitamin in the diet.  (5)

Symptoms of malnutrition include fluid accumulation in the arms, legs, and abdomen. (6)

Starch Belly

Starchy foods are complex carbohydrates and or complex sugars, and include potatoes, tubers, legumes, starchy vegetables, whole grains and breads, refined starches like corn starch.  Terms that can be used interchangeably are starch, starches, or starchy foods in writing, dicussion, and for ease of  understanding.  

A steady diet of starchy foods means a steady stream of glucose entering the blood stream, and chronic high insulin levels.  One role of insulin is to act as a glucose transport into cells.  Glucose can be used for energy and or stored as glycogen.  If there is too much glucose, that may be stored as fat by insulin. Much of this fat is stored as belly fat. (7)

Other problems with whole grain consumption includes: deficient in important nutrients, contain substances poisonous to the human body, need to be cooked which further depletes nutrients, may cause hypertrophy of pancreas, cause unnecessary depletion of enzyme levels, result in flatulence and gas, damage intestinal villi, acid forming and cause cancer and arthritis, skin problems such as dry skin, subcutaneous cysts, exasperate MS, cause brain disorders such as schizophrenia, deplete the immune system and increase susceptibility of head colds and allergies and other infections, promote tooth decay and enamel erosion, may permanently damage infant digestive systems, promote arteriosclerosis meaning hardening via calcification of arteries long term increasing risks of stroke and or heart disease. (8)

Many of the conditions caused by grains also cause and or exasperate abdominal bloating, swelling, and diseases of the abdomen.

Carbohydrates and Starchy Foods

Starchy Foods vs Fruit n Lettuce

 Most starchy foods are also high in oxalate which an contribute to digestive upsets, gas, and bloating.  


High Oxalate Foods 

For optimum digestion, avoid cruciferous veggies like broccoli, kale, spinach, and cauliflower, and root vegetables like carrots, potatoes and tubers, starchy vegetables like beets, some legumes and and beans, grains and bread, some nuts and seeds, and most processed foods.  These foods are high in oxalate which is an irritant to the body. (9)

Immediate symptoms of high oxalate consumption include burning mouth and throat during consumption, digestive upsets including sour stomach, stomach pains, diarrhea, blood in stools, constipation, bloating, gas in its various forms including burping, belching, flatulence, and flatus, breathing and asthma symptoms, acne and skin eruptions, arthritis flare ups, kidney stones and kidney problems, urinary pain and or problems, irritation of the genitalia, body odor, and slowed digestion which makes it difficult to eat enough calories during the day.

Long term symptoms and diseases related to high oxalate consumption include kidney stones and kidney disease, urinary problems, breathing and asthma problems, digestive system irritation and or IBS (Irritable Bowel Syndrome), prevention of calcium absorption and assimilation with risk of osteopenia (bone softening), osteoporosis, and jaw, oral, and dental problems, iron deficiency anemia, and other systemic problems such as calcification of tissues and arteries also known as hardening of the arteries and or arteriosclerosis which can lead to heart problems and cerebrovascular accidents and strokes.  Systemic circulation of calcium oxalate crystals can also cause them to be deposited in the visceral organs, bones, cartilage, and synovial fluid of joints resulting in pain, swelling, and arthritis.

Oxalate Health Impact

Transitioning Not Recommended

One cannot ride two bikes with one bum!

Eating fruit on top of slow digesting food like starchy foods, cooked foods, high protein foods, and high fat foods, can cause the fruit to ferment leading to digestive discomfort and or pain, gas, bloating, and other problems like brain fog.


Cheating with cooked food, and even steamed vegetables, can cause digestive upsets, detox symptoms, and a return of previous conditions. What many members who have tried to transition have experienced is that the longer they eat raw, the cleaner their bodies get.  Their bodies will react violently when they cheat with cooked food.  Symptoms may include upset stomach, vomiting, constipation, headache, acne, and other detox symptoms.  The best way to describe it is sudden onset of flu like symptoms which may last 1-3 days.

Juicing Problems

Some of our 30BaD members have had troubles with juicing such as indigestion, sour and or acidic stomach, nausea and or vomiting, diarrhea, blood in feces, constipation, gas, bloating,  acid reflux,  hyperglycemia aka high blood sugar  and hypoglycemia aka low blood sugar with blood sugar spikes of extreme highs and lows, blurred vision, spikes and or dips in energy, mood swings,  dizziness, brain fog, headaches, migraines, excessive mucus production, acne, skin eruptions such as canker sores, itching, body odors, and inability to absorb and assimilate calories sometimes resulting in weight loss and or malnutrition, and inability to absorb vitamins and minerals and other nutrients in spite of high calorie count. The high sugar and acid content of some juices, as well as a potentially high amount of antinutrients such as oxalic acid, may give some people teeth pain and oral issues such as sores and bleeding gums. 

Juicing Side Effects

Importance of Fiber

The soluble fiber in fruit and some vegetables may gel up inside the intestine.  This fiber slows down digestion and regulates assimilation of nutrients as well as water absorption.  

Diets high in animal products may have little or no fiber, and diets high in grain products that have insoluble fiber actually may scrape and irritate the intestines like shards of glass and do not digest well. 

Fruits are high in soluble fiber which also causes easy elimination of feces just like toothpaste being squeezed from a tube.  This soluble fiber attracts water and turns to gel in the intestines.  (Ref: Soluble vs Insoluble Fiber,  Soluble and Insoluble Fiber)

Without this fiber, nutrients, calories, and carbohydrates can pass right through the system without being digested and assimilated and possibly lead to unwanted weight loss and or malnutrition.


Water makes up more than two-thirds of the weight of the human body. Without water, humans would die in a few days. All the cells and organs need water to function.  Water serves as a lubricant. It makes up saliva and the fluids surrounding the joints. Water regulates the body temperature through perspiration.

Water also helps prevent and relieve constipation by moving food through the intestines. Constipation can cause abdominal bloating, swelling, gas, and even pain.  

Experts usually recommend drinking six to eight 8-ounce glasses of water daily. (10)

Here @30BaD, we have found that drinking about 3-4 quarts a day promotes optimal health and digestion.  

It is important to drink before feeling thirsty as thirst is a signal that your body is on the way to dehydration. (11)

Eating fruit on a dehydrated system may cause digestive upsets and difficulties leading to abdominal swelling.  It is recommended to drink 3-4 cups of water about 20 minutes before a meal, and always ensure that urine is clear.

When to eat and hydrate for max life performance  Posted by Durianrider

Overhydration or Water Intoxication

No, I, the author, am not contradiction myself.  But like most things in life, think of hydration as a Goldilocks zone.  Dehydration can cause many health issues, but so can overhydration.  Drinking too much water can cause digestive upset, nausea, vomiting, and other health issues such as hyponatremia (low sodium levels) which can interfere with electrolyte levels, brain function, along with many body functions.  

Only drink what is needed for health and digestion, but not too much.  It is recommended that urine color be a light yellow color.  This chart may help...

Unripe Fruit

Unripe fruit is difficult to digest.  Always make sure to pick ripe fruit.  Ripe fruit may contribute to other health benefits as well as promoting oral and dental health.  

How to Pick Ripe Fruit   Posted by Freelee



Never try to self diagnose or treat a disease or symptom.  Many diseases and conditions have similar symptoms.  In case of a medical emergency, seek medical care to get a proper diagnosis for abdominal bloating, and then make a plan of therapy and nutritional treatment.

To prevent abdominal bloating, stay properly hydrated and always pick ripe fruits.  Avoid symptoms of edema and interstitial fluid by not eating salt.  Focus on raw fruit and lettuce greens and avoid vegetables high in oxalate such as spinach and kale, and avoid starchy foods and grains.  And, last but not least, avoid cheating.

I had steamed spinach last night and had heartburn, big time farting, bloating and a massive blowout this morning. (The blowout is a good thing!) my stomach is super flat today!

That food combining chart is great! I was so confused about what goes with what.

If you can handle spinach that is ok.  Some of our members including myself are sensitive to spinach.  This blogpost explains some reasons why.  

Spinach might be good for some people, but lettuce greens might be better:-D

Many of our members, including athletic and body builder types, like to eat 1/2-2 heads or more of lettuce greens a day.  

They are easier to digest, and lower in antinutrients:

For the most part, I try to focus on science verses what any individual has to say about something.  Just because someone is a guru or has a large following does not always mean everything they say is correct. 

While it does not happen to everyone, and is a rare process, the body can change glucose to fatty acid form.  Excess glucose, fat, and protein can be stored in cells making us look bigger.  

A fact people often overlook is that insulin unlocks fat cells too, and promotes storage in fat cells.   

As far as your personal bloating, I am not sure what the  cause.  Not all bloating is body fat.  I am not sure of your habits such as are your RT4 or not, but our bodies do hold onto more water when we eat starches.  Water is used in the hydrolyses process of breaking the starch bonds into smaller glucose units.  

Also, some people do retain water when adding table salt to the diet.  

You can rereada this blog post for ideas and it has been edited with a food combining chart that helps some people.

Sorry this reply is a little a bit late, and I hope you have figured out your issues by now.  

Yes, some people have problems with celery because of cellulose, that is indigestible fibers, and it might fall under the moderate to high oxalate category too.  

You might want to focus on low oxalate foods and see if you feel better.

" If there is too much glucose, that may be stored as fat by insulin. Much of this fat is stored as belly fat." - ORLY? i'm wondering what Dr. McDougall would say about that..

seriously though, i have permanent bloating as well and don't know the reason (

Comment by Carolina Antonia on April 16, 2014 at 3:33am

I always get problems after a big romaine and celery salad... with just lemon juice.

I get soo bloated that my stomach hurts because of the inflammation... maybe i don't chew enough? i try too, maybe its too much celulose or fiber that my body its not used to?
Can somebody give me an advice? thanks!
