Can you really flush the fat away?

I had a client talk to me last week about something they had seen online about 'Fat Burning' and how they had been told it can be 'flushed' out with the right teas and other potions.

Never in all of the science classes I’ve taken and in all of the years I’ve been studying human metabolism and health, have I ever heard of a ‘flush’. Turns out, the person who posted the picture - a ‘health coach’ - said that’s what happens to fat cells when we lose weight. Of course, she was selling a product.

Another person on the Internet floated the claim that the ‘flush’ happens when we lose weight.

This person said that after the cells release fat, they temporarily fill with water, making you feel ‘squishy’. She said that this water retention occurs because ‘the fat cells are hoping to fill up again with fat’.

Apparently, this person doesn’t understand science because, despite her compelling description, she’s absolutely wrong.

Our fat cells don’t fill with water after they release triglycerides during weight loss. They just sort of…wait there, like when the train takes half an hour reversing into Killarney Station and it’s baltic outside!

The question is where does it go? And maybe there isn’t a ‘flush,’ but do fat cells disappear or leave the body when they’re empty?

All very good questions, and all about to be answered in this week’s and next week's article.

Warning: People who use words like 'flush' and 'burn' about the complex human metabolic process should be ignored. But you knew that already.

What are fat cells?

Contrary to popular belief, we aren’t born with all of our fat cells. We accumulate them – at least what’s determined to be our baseline number – until well into our teens.

Most of the fat in our bodies is what we refer to as white fat, or WAT (White Adipose Tissue). White fat stores triglycerides for energy, cushions our organs, keeps us warm, and produces hormones.

When we eat fat, it gets broken down and metabolised by the liver into triglycerides. These are stored in the fat cells, liver, and to a small extent, in muscle. When your body needs energy, it releases the triglycerides into the bloodstream in a process called lipolysis.

The body tries to maintain a balance of ‘lipid turnover’, which is the name given for the process of storing and removing triglycerides in fat cells for energy. Of course, if you go into calorie deficit, this balance tips, and you lose weight.

Recent research measuring lipid turnover rates showed that lipid removal slows as we age – basically, our cells continue to take up fat, without losing as much of it. That may make it harder to lose weight as we get older.

In Part 2 next week, we'll look at macronutrients and what happens to fat when we lose weight.

Missing Killarney chef located dead in UK


A 34-year search for missing former Killarney chef Patrick (Patsy) O’Sullivan ended following confirmation that he was located deceased in the UK.


Patsy was 35 years old when last seen by relatives in Lombardstown, County Cork, during the Easter Bank Holiday weekend in April 1992. At the time of his disappearance, he was working as a chef in Waterville, having previously worked across several Killarney hotels. He was scheduled to attend a family Christening shortly after returning from Kerry, but never arrived.
Despite decades of public appeals, including features on RTÉ’s Crimecall, his location remained unknown.
Investigations revealed that Patsy moved to the UK and changed his name to Patrick Aldridge in 1995, adopting the surname of his partner who passed away in 2022. He passed away from natural causes on July 5, 2024, living just over an hour away from his brother who also passed away in the UK last year.
Speaking on Cork’s 96FM, his brother Jerry O’Sullivan confirmed the family finally received closure following renewed efforts led by Garda PJ Roche and investigating officers. He noted that while unanswered questions remain about why Patsy started over fresh, the family is grateful for the work that brought final answers.
An Garda Síochána confirmed the missing person case is closed and thanked the public for their assistance over the years.

Speed cameras go live at Farranfore level crossing

Speed cameras go live at Farranfore level crossing

An Garda Síochána, Iarnród Éireann, Transport Infrastructure Ireland, and Kerry County Council put new safety enforcement cameras into operation at the Farranfore level crossing this week.

The GoSafe system, which went live at 12pm on Tuesday, October 6, automatically detects vehicles running red lights or breaking the speed limit as they approach and cross the railway track.

Farranfore is only the second level crossing on the national rail network to feature the technology, following a trial at Merrion Gates in Dublin where driver compliance reached 99.7 per cent. Up to six crossing locations nationwide are slated to receive the units.

The system targets two distinct traffic violations. Proceeding past a stop line when red lights are flashing carries an automated Fixed Charge Notice of €80 and two penalty points, rising to five penalty points upon court conviction. Speeding violations trigger a €160 fine and three penalty points, which can increase to five points and fines up to €1,000 if prosecuted in court.

Iarnród Éireann highlighted excessive approach speed as a key safety factor at the Farranfore junction. Nationwide, 31 incidents involving vehicles or bicycles colliding with automated level crossing gates have occurred in 2026 to date, up from 23 in 2025.

Highlighting the risk to local road users, Road Safety Officer with Kerry County Council Declan Keogh said: : “The new safety cameras at Farranfore railway crossing serve as a dual-safety mechanism, for road users and for rail users and operators. I would urge all motorists to think twice before taking that chance to get across the railway line when the warning lights have activated and the barriers are lowering. All too often those chances have proved unsuccessful, with serious consequences.”

Iarnród Éireann Chief Executive Mary Considine noted that interfaces between road and rail traffic represent one of the primary safety risks on the network, adding that automated cameras encourage drivers to reduce speed and obey active signals.

Assistant Commissioner Ferry of the Garda National Roads Policing Bureau welcomed the joint venture, stating that technology-led enforcement will significantly assist in maintaining safety across shared transport networks.

50km/h zone enforced at Farranfore

Motorists traveling through Farranfore are reminded that the speed limit on the approach to and across the railway crossing is strictly 50km/h.

While automated safety systems enforce both signal compliance and vehicle speed, the 50km/h limit remains the maximum legal speed on the N22 section approaching the crossing gates.

The newly activated GoSafe cameras record vehicle speeds automatically in both directions. Any motorist detected exceeding the 50km/h threshold will automatically receive a €160 Fixed Charge Notice alongside three penalty points applied to their driving licence.

Local authorities and Gardaí advise drivers approaching Farranfore from both the Tralee and Killarney directions to adjust their driving speed early, monitor active signals, and prepare to stop safely when warning lights activate.
