Can a Fatty Liver Cause Weight Gain? The Truth About Metabolism, Ageing & Liver Health

Welcome back to Part 3 of our Liver Series Campaign. I’ve loved talking about the power of the liver with you, and today we’re focusing on one of the most common questions I hear: can a fatty liver cause weight gain?

And the answer is yes, absolutely. Because your liver isn’t just your detox organ, it’s the metabolic powerhouse behind how your body processes fat, regulates blood sugar, and even manages hormones. 

In this blog, we’ll look at how the liver connects to fat loss, metabolism, and ageing, why fatty liver isn’t just caused by alcohol, and the simple reset plan that can put your body back into balance before the festive season (dare we say it?).

Can a Fatty Liver Cause Weight Gain?

Your liver plays a central role in fat metabolism, as it decides whether fat is burned for energy or stored in your tissues. When the liver becomes fatty or sluggish, this process gets disrupted, so instead of burning fuel efficiently, it stores fat, particularly around the belly. 

This is why so many people with fatty liver also struggle with stubborn weight gain and low energy, so it’s not simply about willpower, it’s about physiology. 

And here’s something important: fatty liver isn’t just linked to alcohol. Non alcoholic fatty liver disease (NAFLD) is sadly on the rise, and in much younger people too! It’s often driven by high sugar diets, processed foods, chronic stress, and poor sleep. So you can be doing all the right things and still struggle, if your liver isn’t functioning optimally.

Preparing the Liver First: Our Liver Cleanse

Before thinking about fat loss and metabolism resets, I always recommend the first step to be prepping the liver. This isn’t an essential step, but it’s a hugely beneficial one, as it helps clear the backlog so your body is ready to respond.

Here’s our Liver Cleanse, and why supporting your liver first makes all the difference:

Natroceutics Milk Thistle Bio-Active: 

This isn’t just your average milk thistle. Natroceutics uses a full spectrum extract enhanced with phospholipid technology (which means much better absorption), offering stronger benefits than standard formulas.

It is also clinically proven to stay in the system for 24-48 hours to support detoxification and also helps to repair and regenerate liver cells. And we can back that up with human studies, which have shown it can:

• Help reduce markers of liver stress and improve enzyme balance (especially in NAFLD).

• Support hormone balance, insulin sensitivity and blood sugar regulation.

• Help clear hormonal breakouts, leaving skin brighter and clearer.

• Improve overall energy, mood, longevity and quality of life.

• Offer therapeutic benefits even in more serious liver concerns like NAFLD and cirrhosis.

Glutathione + SOD (Superoxide Dismutase)

Glutathione is becoming more popular, and I’m not surprised. It’s the body’s master antioxidant, and is essential for neutralising toxins and repairing liver cells. Natroceutics blends Glutathione with SOD, often called ‘the youth molecule’, and together they:

• Support all phases of liver detox, making toxins water soluble and easier to eliminate.

• Reduce inflammation and oxidative stress throughout the body.

• Revive other antioxidants like vitamin C and E.

• Help protect against fatty liver and cirrhosis.

• Boost immune and digestive health for total body resilience.

Does the Liver Affect Metabolism?

Absolutely. Your liver determines how carbs, fats, and proteins are processed and whether they’re stored or burned. If it’s sluggish, metabolism slows down, energy dips, and fat accumulates.

Once your liver has been supported with Milk Thistle and Glutathione, the next step in the reset is Bergamot-HT, from our Fat Loss & Longevity bundle, where it helps:

• Support cholesterol balance

• Improve fat metabolism.

• Reduce oxidative stress in the liver.

• Support a reduction in visceral fat (the deep belly fat that’s metabolically active and more problematic).

By improving the way your liver handles fats, Bergamot acts like a metabolic reset button, giving your body a cleaner slate for energy and weight balance.

Does Fatty Liver Cause Insulin Resistance?

One of the biggest links between liver health and weight gain is insulin resistance. A fatty liver interferes with insulin’s ability to do its job, meaning more sugar gets stored as fat. This doesn’t just lead to belly weight gain, it drives cravings, fatigue, and hormonal imbalances.

This is where Berberine comes in, part two of our Fat Loss & Longevity bundle. Often referred to as nature’s metformin (the medication commonly prescribed for diabetes), it has similar blood sugar balancing effects but with even more benefits like:

• Improving insulin sensitivity.

• Reducing sugar cravings and balancing appetite.

• Lowering blood sugar and cholesterol markers.

• Activating AMPK, the metabolic switch that turns the body into fat burning mode.

The idea behind the combination of these supplements, is not a quick fix, but it’s about correcting the underlying imbalances so your body can finally start responding the way it should. 

Your 3 Month Liver Reset Plan:

Here’s how the cleanse looks in practice:

Month 1: Prep and cleanse the liver with Milk Thistle Active + Glutathione/SOD (in our Liver Cleanse bundle).

Month 2: Layer in Bergamot-HT for fat metabolism support. (Fat Loss & Longevity bundle)

Month 3: Add Advanced Berberine to restore insulin sensitivity and balance blood sugar. (Fat Loss & Longevity bundle)

Pair this with simple lifestyle foundations like hydration, fibre, cruciferous vegetables, and gentle daily movement, and you’ve created the conditions for your body to lose weight safely, boost energy, and age gracefully.

Time to Reset

As we age, liver efficiency naturally declines. Detox slows down, fat metabolism becomes less effective, and inflammation increases, all of which accelerate ageing and make weight management harder.

But ageing doesn’t have to mean decline. Studies show that maintaining healthy liver function improves longevity, skin vitality, hormonal balance, and reduces risk of metabolic diseases.

This is why autumn is the perfect season to reset, it’s about supporting your liver now, so you move into autumn with energy, resilience, and balance.

If you’ve felt stuck in your weight loss goals despite doing everything right, your liver may be the missing link. Support it first, for better metabolism, fat loss, and healthy ageing.
