Functional Medicine Approach to Fatty Liver

Fatty liver disease occurs when excess fat accumulates within the liver.

The newer medical term MASLD — Metabolic Dysfunction-Associated Steatotic Liver Disease — reflects an important reality: in many individuals, fatty liver is closely connected with broader metabolic dysfunction such as insulin resistance, excess visceral fat, Type 2 Diabetes, elevated triglycerides and abnormal body composition. NIDDK

At RH+, I therefore do not look at fatty liver as an isolated liver problem.

With Prashantt J Wadhaawan, Functional Medicine Practitioner and Founder of RH+, the assessment looks at the person’s liver findings alongside nutrition, insulin regulation, glucose, triglycerides, body composition, physical activity, sleep, alcohol exposure and broader metabolic health.

Online functional medicine consultations are available across India.

Fatty Liver Is Often a Metabolic Problem Expressing Itself in the Liver

One of the patterns I commonly see is that fatty liver rarely appears alone.

The same person may also have:

• insulin resistance
• elevated fasting insulin
• increased visceral fat
• obesity
• elevated triglycerides
• impaired glucose regulation
• Type 2 Diabetes
• elevated uric acid
• poor dietary quality
• low physical activity
• inadequate muscle mass
• poor sleep
• chronic stress

These conditions frequently overlap because they share many of the same metabolic drivers.

Obesity, insulin resistance, Type 2 Diabetes, high triglycerides and metabolic syndrome are all recognised risk factors for MASLD. NIDDK

“Fatty liver is rarely just a liver problem. It is usually a metabolic problem expressing itself in the liver.” — Prashantt J Wadhaawan

Fatty Liver Can Be Silent

One reason fatty liver is frequently overlooked is that many people have few or no obvious symptoms.

Some may experience fatigue or discomfort in the upper-right abdomen, but many discover fatty liver incidentally during:

• abdominal ultrasound
• routine health screening
• investigation of elevated liver enzymes
• metabolic assessment

Importantly, a person can have significant fatty liver even when they feel relatively well. NIDDK

That is why I look at the person’s imaging, metabolic profile and health history together rather than relying on symptoms alone.

How I Assess Fatty Liver

As with the other metabolic conditions I work with, I begin with the person rather than immediately prescribing a “liver detox.”

My assessment typically includes:

Health Risk Assessment

A detailed questionnaire looks at symptoms across different physiological systems.

Medical History

I review:

• existing liver diagnosis
• diabetes or prediabetes
• insulin resistance
• weight history
• medication use
• alcohol consumption
• family history
• previous liver abnormalities
• other metabolic conditions

Nutrition

I pay particular attention to:

• overall food quality
• refined carbohydrates
• sugary foods and beverages
• fructose exposure
• dietary fat quality
• saturated-fat intake
• seed-oil intake
• ultra-processed foods
• alcohol
• fibre
• fruit intake
• overall calorie intake

Lifestyle

I assess:

• exercise
• daily movement
• resistance training
• sleep
• stress
• body composition
• visceral-fat patterns

Existing Reports

I prefer to review existing investigations before asking for additional testing.

Markers & Investigations To Review In Fatty Liver

Depending on the individual, I may review:

• ALT
• AST
• GGT
• ALP
• bilirubin
• triglycerides
• HDL and broader lipid profile
• fasting glucose
• HbA1c
• fasting insulin where relevant
• C-peptide where useful
• uric acid
• ferritin where indicated
• kidney-function markers
• body composition
• visceral fat
• abdominal ultrasound
• FibroScan or elastography where appropriate

Additional liver assessment may be required depending on the person’s risk profile.

Ultrasound

Ultrasound is commonly used to identify liver steatosis and is often how people first discover they have fatty liver.

It gives us useful structural information but does not completely define the severity of liver inflammation or fibrosis.

FibroScan & Fibrosis Assessment

When there is concern about fibrosis or more advanced disease, non-invasive fibrosis assessment such as elastography/FibroScan may be appropriate.

AASLD guidance emphasises identifying people at risk of advanced fibrosis rather than simply confirming that liver fat is present. AASLD

Normal Liver Enzymes Do Not Always Mean a Normal Liver

This is an important point.

ALT, AST and GGT can provide useful information, but liver enzymes should not be interpreted as the complete assessment of liver health.

A person can have steatotic liver disease even without dramatically elevated liver enzymes.

So my objective is not simply:

“Get ALT into range.”

I want to see the enzymes interpreted alongside:

imaging + triglycerides + glucose regulation + insulin physiology + body composition + clinical history.

This is why follow-up imaging can be particularly useful when fatty liver was initially confirmed through ultrasound.

What Usually Drives Fat Accumulation in the Liver?

There is rarely one cause.

In metabolic fatty liver, contributing factors can include:

• insulin resistance
• excess calorie intake
• visceral obesity
• poor diet quality
• excess refined carbohydrates
• sugar-sweetened beverages
• excessive fructose exposure
• sedentary lifestyle
• abnormal lipid metabolism
• poor metabolic health
• genetic susceptibility

Dietary fructose—particularly when consumed through added sugars and sweetened beverages—has been investigated as a contributor to fatty liver. NIDDK

The important distinction is that whole fruit is not physiologically equivalent to drinking large quantities of fructose-containing beverages.

My First Nutritional Priorities for Fatty Liver

The goal is not to prescribe the same “liver diet” to everybody.

Depending on the person’s metabolic profile, I commonly start by modifying several areas.

Reduce Refined & Highly Processed Foods

This may include reducing:

• sugary beverages
• desserts
• refined starches
• ultra-processed foods
• excessive snacking

Reduce Excess Saturated Fat

High saturated-fat intake deserves attention, particularly when metabolic health is already compromised.

Current dietary guidance for fatty liver generally favours replacing saturated fats with unsaturated fat sources rather than simply adding more dietary fat. NIDDK

Reduce Seed Oils

In my own practice, I also pay attention to seed-oil intake, particularly when large amounts are coming from:

• fried foods
• restaurant foods
• packaged foods
• ultra-processed foods
• oils that have been repeatedly heated

I often reduce these foods as part of improving overall dietary quality.

Reduce Excessive Fructose Exposure

I particularly look for:

• soft drinks
• packaged juices
• large amounts of fruit juice
• sweetened beverages
• high-fructose processed foods
• excessive intake of very sugar-dense foods

What About Fruits in Fatty Liver?

I do not automatically remove fruit from everyone with fatty liver.

But the amount and type may need to be considered according to the individual’s:

• glucose regulation
• insulin resistance
• triglycerides
• total calorie intake
• body composition
• overall diet

I may reduce excessive intake of very fructose-dense fruits in some individuals while favouring appropriate portions of whole fruits rather than juices.

I also commonly encourage citrus fruits where appropriate as part of a varied whole-food diet.

The important distinction is

whole fruit ≠ fruit juice ≠ sugar-sweetened beverage.

Can a Low-Carbohydrate Diet Help Fatty Liver?

It can be useful for some people, particularly when insulin resistance, high triglycerides and poor glucose regulation are present.

I sometimes use a lower-carbohydrate nutritional strategy, but I do not assume everyone needs permanent ketogenic eating.

The dietary strategy needs to consider:

• glucose regulation
• fasting insulin
• triglycerides
• liver health
• weight
• activity
• food quality
• sustainability

Someone eating fewer carbohydrates but consuming excessive calories, poor-quality fats and inadequate fibre may not necessarily have created an optimal liver-health diet.

The objective is metabolic improvement — not loyalty to a dietary label.

Fatty Liver & Insulin Resistance

Insulin resistance and fatty liver frequently occur together.

As insulin sensitivity worsens, the liver can become increasingly involved in abnormal glucose and lipid metabolism.

This is why I rarely assess fatty liver without considering:

• fasting glucose
• HbA1c
• fasting insulin where appropriate
• triglycerides
• body composition
• visceral fat

Fatty Liver & Type 2 Diabetes

Type 2 Diabetes substantially overlaps with MASLD.

People with Type 2 Diabetes may have a higher risk of developing more progressive forms of fatty liver disease, which makes appropriate assessment of fibrosis particularly important. NIDDK

Someone with:

Type 2 Diabetes + fatty liver + high triglycerides + visceral obesity

therefore needs to be viewed as having a broader metabolic problem rather than four completely unrelated conditions.

Explore Type 2 Diabetes →

Fatty Liver & High Triglycerides

Elevated triglycerides commonly accompany insulin resistance and fatty liver.

This relationship is one reason triglycerides are an important outcome marker in my metabolic programmes.

If liver enzymes improve but triglycerides remain very high and visceral obesity remains unchanged, I would not consider the metabolic problem fully addressed.

Alcohol & Fatty Liver

When I am actively trying to improve fatty liver, I generally prefer no alcohol, particularly where imaging has already confirmed liver fat or liver enzymes are abnormal.

Alcohol adds another metabolic and toxic burden to the liver and can complicate the distinction between metabolic and alcohol-related liver disease.

A person’s alcohol history is therefore an important part of the assessment. NIDDK

Weight Loss & Fatty Liver

For someone with excess body fat, weight loss can be one of the most effective interventions.

Evidence suggests that approximately 3–5% weight loss can reduce liver fat, while larger reductions—often around 7–10%—may be needed for greater improvements in inflammation and fibrosis. NIDDK

But I do not want the person to lose weight through:

• starvation
• extreme calorie restriction
• excessive cardio
• substantial muscle loss

The better objective is:

less visceral fat + healthier liver + preserved muscle + better metabolic function.

Supportive Foods in Fatty Liver

Rather than talking about a generic “liver detox diet,” I prefer to build a nutrient-dense whole-food pattern.

Foods I may incorporate depending on the individual include:

• vegetables
• citrus fruits
• apples
• carrots
• ginger
• herbs and spices
• fibre-rich whole foods
• appropriate protein sources

No individual food “cleans” the liver.

Their value comes from being incorporated into a wider nutritional pattern that improves metabolic health.

Curcumin, Milk Thistle, NAC & Liver-Supportive Supplements for Fatty Liver

I sometimes consider compounds such as:

• curcumin
• milk thistle / silymarin
• N-acetylcysteine — NAC

depending on the individual’s circumstances.

However, I do not make these the foundation of fatty-liver management.

Evidence for many supplements in MASLD remains variable, and supplement quality, dosing, medication interactions and individual medical circumstances matter.

NIDDK specifically advises people with fatty liver to discuss supplements and herbal remedies with their healthcare professionals because some products can themselves cause liver injury. NIDDK

My approach is: metabolic fundamentals first → targeted supplementation second.

“My priority is to improve the metabolic environment first. Supplements come later.”

Common Mistakes I See in Fatty Liver

Focusing Only on Liver Enzymes

Normalising ALT does not automatically mean the whole metabolic problem has resolved.

Taking “Liver Detox” Supplements Without Changing Lifestyle

Milk thistle, NAC or curcumin cannot compensate for persistent visceral obesity, poor food choices, inactivity or excessive alcohol.

Drinking Fruit Juice Because It Is “Healthy”

Whole fruit and concentrated fruit juice are metabolically very different.

Following Extreme Diets Indefinitely

The goal is not simply rapid weight loss.

It is sustainable improvement in liver and metabolic health.

Ignoring Triglycerides

Fatty liver often exists within a broader lipid and insulin-resistance pattern.

Doing Only Cardio

Resistance training and muscle preservation also deserve attention.

Continuing Alcohol

When liver fat has already been established, I generally remove alcohol while working to improve the underlying metabolic picture.

What Are We Actually Trying to Improve?

The goal is not just a lower ALT number.

My principal outcomes are:

• improvement in liver fat on follow-up ultrasound where appropriate
• healthier ALT, AST and GGT patterns
• lower triglycerides
• improved fasting glucose and HbA1c
• better insulin regulation where relevant
• reduced visceral fat
• improved body composition
• better overall metabolic health

A particularly meaningful outcome is seeing the imaging, metabolic markers and body composition improving together.

“Fatty liver is not just about the liver. The real goal is to improve the metabolic state that is driving it.” — Prashantt J Wadhaawan

Fatty Liver FAQs

Can fatty liver be reversed?

Liver fat can improve substantially in many people, particularly with sustained weight loss, improved nutrition and physical activity. Earlier disease is generally more amenable to improvement than advanced fibrosis or cirrhosis. NIDDK

What is MASLD?

MASLD stands for Metabolic Dysfunction-Associated Steatotic Liver Disease, the newer terminology used for what was previously commonly called NAFLD when liver steatosis occurs in the appropriate metabolic context. NIDDK

Can liver enzymes be normal with fatty liver?

Yes. Liver enzymes alone cannot reliably exclude steatotic liver disease or more significant pathology. Imaging and fibrosis-risk assessment may therefore be important depending on the clinical context.

Does insulin resistance cause fatty liver?

Insulin resistance is strongly associated with MASLD and contributes to the metabolic environment in which excess liver fat develops, but the disease is multifactorial.

Does fatty liver cause high triglycerides?

Fatty liver and elevated triglycerides frequently coexist as part of broader insulin resistance and metabolic dysfunction. Neither should automatically be considered the sole cause of the other.

Should I stop fruit if I have fatty liver?

Not automatically. Whole fruit can form part of a healthy diet. Fruit juices, sugar-sweetened beverages and excessive concentrated sugar intake are different issues.

Is fructose bad for fatty liver?

High intake of fructose-containing added sugars, particularly from sweetened beverages and processed foods, has been associated with fatty liver risk. This should not be interpreted as meaning all whole fruit needs to be eliminated. NIDDK

Is keto good for fatty liver?

A lower-carbohydrate approach can be useful for selected people, but keto is not mandatory. The overall calorie intake, fat quality, fibre, metabolic response and sustainability of the diet matter.

Should I stop seed oils for fatty liver?

In my practice, I commonly reduce seed-oil-heavy fried and ultra-processed foods as part of improving dietary quality. However, current clinical guidelines do not establish avoidance of all seed oils as a specific MASLD therapy. Evidence is stronger for reducing excess saturated fat and improving overall dietary quality.

Is milk thistle useful for fatty liver?

Milk thistle has been studied in liver disease, but evidence is not strong enough to replace established interventions such as weight management, appropriate nutrition and exercise.

Can NAC help fatty liver?

NAC has biological roles related to glutathione metabolism and has been investigated in liver health, but it should be considered an adjunct rather than established primary therapy for MASLD.

Should alcohol be stopped?

In my practice, I generally remove alcohol when someone has confirmed fatty liver. Individual medical recommendations should also consider the type and severity of liver disease.

Is ultrasound enough to monitor fatty liver?

Ultrasound can identify steatosis but has limitations. Depending on the person’s risk, fibrosis assessment such as FIB-4, elastography/FibroScan or specialist evaluation may be necessary.

Can I consult online for fatty liver?

Yes, where remote functional-medicine support is appropriate and relevant medical/hepatology care continues when necessary.

Work With Prashantt J Wadhaawan

If an ultrasound has shown fatty liver, the next question should not simply be:

“Which liver supplement should I take?”

The more useful question is:

“Why is fat accumulating in my liver, and what does the rest of my metabolic health look like?”

At RH+, we bring together:

liver imaging + liver enzymes + insulin/glucose regulation + triglycerides + body composition + nutrition + exercise + sleep

to understand the wider picture.
