Your Sustainable Weight Loss with Low-fiber Diet

If you’re an avid weight watcher or a fitness-conscious person, you’ve probably stumbled upon a low-fiber diet or caught wind of its health benefits, but how effective is it for weight loss? Today, the internet is bursting at the seams with all the “groundbreaking”dietary approaches that claim to be the weight loss magic bullet you were searching for.  But you shouldn’t take the bait and accept the information at face value because it’s your health that is at stake. Always put your investigator hat on and look for clues that might indicate whether this diet is actually beneficial or whether it is just another nutrient-deficient unsustainable fad diet in disguise. Low-fiber eating approach may appear really effective, but there are many nuances, so let’s stay on the safe side and take a closer look at it.

What is a low fiber diet and what are its benefits?

Fiber consists of plant material and the body cannot fully digest it, so the crux of a low-fiber diet is in avoiding products with high fiber content (1). A low-fiber diet (or low residue diet) helps to reduce the amount of undigested food, and therefore reduce bowel volume. This diet is usually recommended for a short period of time. 

One should consult a nutritionist to make a personal menu. Pay attention that due to the restrictive nature of this diet, you may need to include some vitamins in your diet. This is also a question that should be agreed upon with a specialist.

In most cases, a low-fiber (also called low-residue) diet limits fiber intake to around 10 – 15 grams per day (2). Sometimes people need to stick to this diet for some time after going through a gut surgery or when they are trying to alleviate the symptoms of cerating diseases because low fiber foods give your bowel a rest. Note that this diet is never considered as a simple weight loss diet for everyone, it should be prescribed and overseen by a doctor. Low-fiber diet as any other restrictive dietary approach has its pros and cons, so let’s look at them:

low residue diet

Benefits of a Low Fiber Diet

  • It reduces the amount of undigested food in your intestines and bowels
  • Low-fiber diet reduces the amount of stool
  • The diet eases the work of the digestive system
  • This diet is beneficial for people with inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease, particularly when they are experiencing a flare-up
  • It reduces bloating, diarrhoea, eases abdominal pain and stomach cramps 
  • As a result, more nutrients are absorbed as transit time in the intestines increases (food moves more slowly through the digestive system) (3).

Side Effects of a Low Fiber Diet

  • It may cause nutritional deficiencies, which can lead to a number of health problems
  • Since high-fiber foods are satiating yet low in calories, they are often considered helpful for weight loss. Thus, a low-fiber diet can lead even to weight gain
  • During this diet you may need to take more vegetable and fruit juices along with multivitamin supplements.

A low-fiber diet can help calm your intestinal walls and help you feel better if you suffer from a digestive system disorder. Follow a low fiber diet only if your doctor advises you to do this. If you experience stomach pain during a low residue diet, consult a doctor immediately. 

You should know that this eating plan is nutritionally limiting, restricting, and actually not intended directly for weight loss. If you don’t do it right, it may cause a number of side effects (6).

Dairy products

You can consume milk and other dairy products but in moderation. However, if you are suffering from lactose intolerance, you should consider staying away from dairy.

Meat

The good news about a low-fiber diet is that there is little restriction on meat, fish, and poultry consumption. You can eat beef, chicken, lamb, fish, and pork meat if it is soft and tender. You should, however, avoid processed meat products like sausages and cold cuts, as well as tough or fatty meats with gristle or skin. You can also eat eggs, tofu and smooth peanut butter for alternative sources of protein.

Fats, seasonings and sauces

You can eat the following products and other smooth sauces or condiments in moderation as a part of your low-fiber diet:

  • Margarine
  • Butter
  • Oils
  • Ketchup
  • Mayonnaise
  • Sour cream
  • Jelly
  • Honey
  • Soy sauce
  • Salad dressing (without seeds)

You can also eat simple cakes, cookies, pudding, custard, pretzels, hard candies, ice cream. Just be mindful that you will want to avoid too much fat and sugar if you are on this diet to give your digestive system a break. When it comes to drinks, you should think twice about drinking coffee and soda (caffeine can irritate your stomach). But you are encouraged to drink fresh vegetable juices.

A few important notes for those who want to try a low-fiber diet

The role of exercises

Regular exercises will keep you active, strengthen your muscles and bones. It may also help prevent constipation on a low-fiber diet. Try to include at least 20 minutes of training in your daily routine. Walking, jogging, jumping, cycling and yoga are recommended.

How to return to fiber foods again?

You should start including one fiber-rich food per day, and if it doesn’t cause any adverse symptoms, you may continue to consume it. The amount of fiber you need depends on your age and sex.

  • Men (50 years or younger): 38g, over 50 – 30g
  • Women (50 years or younger: 25g, over 50 – 21g (2)

Avoid eating all your daily fiber allotment in one go. The best way to get enough fiber is to eat raw vegetables, fruits with skins, beans, nuts, whole grains, and seeds. There is also a low fat high fiber diet that also may be effective for weight loss.

Drink more

Pay attention to keep your fluid intake high. This will also help you avoid constipation while on this diet plan.

Avoid fat and sugar

Choose foods that are lower in fat and added sugar when you are on this diet. These can also irritate the intestine and cause discomfort.

Supplements are needed

This diet does not include all the nutrients your body needs, that is why you’ll likely have to take multivitamins or other supplements. Don’t roll the dice with your health and consult your doctor or dietitian (3).

Stick to this type of diet only if your doctor has recommended it. Only a professional will tell you how long you need to be on this diet. It always depends on your medical condition and state of health in general. A professional dietitian may create an individualized plan for you. As you see, a low-fiber diet is not a weight loss cure-all,  so don’t gamble with your health and look for other ways to peel off a couple of extra pounds that you want gone so bad.
