Can Deepfakes Damage Your Health?
Today, more of us than ever are turning to the internet and technologies like remote medicine for healthcare services and advice.
But given the explosion of AI-generated fake news and disinformation online, is this potentially putting our health at risk?
This is a worrying question we have to tackle head-on in the age of deepfakes – highly realistic AI-generated content showing things that never happened or people saying things they never said.
Most people first came across deepfakes as often viral, entertaining novelties like DeepFake Tom Cruise. But their darker side takes in political manipulation, election interference, conspiracy theories and non-consensual pornography.
However, some of the most nefarious uses are increasingly in healthcare, where accurate, factual information and trust are critically important to good outcomes.
From faked celebrity endorsements to harmful AI-generated medical advice, are deepfakes fueling a dangerous wave of misinformation and disinformation that could seriously damage our health?
Fake celebrity endorsements have always been a problem online—as Oprah has spoken about her frustration over fake ads for diet pills and supplements for many years. But in an age when virtually anyone can easily create a convincing video of anything they want in seconds, the problem is significantly amplified.
Tom Hanks is one of the high-profile figures who has felt the need to issue a public warning that deepfake video of him promoting 'miracle cures and wonder drugs' are not genuine and could pose a threat to health.
If you wouldn't necessarily trust Tom Hanks to give you medical advice anyway, what about a famous TV doctor? There have been several cases where deepfake videos of well-known professionals have been used to entice viewers into buying bootleg or illegal medicines for diabetes and high blood pressure.
Charities can be targets too – in Australia Diabetes Victoria said that footage of experts endorsing supplements as an alternative to medical treatment for diabetes was deepfake.
The people featured in deepfake health disinformation don't even have to be real as long as they seem trustworthy. A wave of fake and potentially dangerous medical advice in TikTok videos prompted a New York Post investigation, which found that fake clips featuring entirely made-up people can be created with a few clicks on an app.
There are also fears that deepfakes could be used to spread misinformation about public health issues like pandemics and vaccinations. Disinformation spread by fake celebrities or healthcare professionals could impact compliance with public health advisories like mask-wearing or hand-washing, reducing their effectiveness.
Deepfakes threats to healthcare are particularly concerning because of the importance of trust. After all, a society that doesn't trust healthcare professionals probably won't stay healthy for long. If people genuinely have difficulty distinguishing between genuine medical advice and dangerous disinformation, the consequences for everybody could be severe.
The important thing to remember is that deepfake technology is as easy to spot and unconvincing now as it will ever be. Tomorrow, like all AI, it's going to be much more sophisticated.
This is a scary prospect if you're already wondering how you're supposed to survive in a world where Oprah Winfrey and Tom Hanks are trying to kill you with bad advice.
Lawmakers in some areas are starting to get to grips with the sale of the challenge. The EU AI Act, China's Generative AI Measures regulations, and various US state-level laws, all contain measures aimed at preventing harm.
But as with the explosion in so many other digital crimes—phishing scams, ransomware and the like—there's a limit to what the law will do. As an international crime with a very low barrier to entry, it's unlikely to be stamped out any time soon.
For most of us, the answer lies in ourselves, which means taking on the responsibility of developing our own critical thinking and deepfake-era survival skills.
This starts by understanding the threats. It's possible that the employee of a Hong Kong business who transferred $25 million to scammers on the instructions of a deepfake of her CEO's voice might not have done it if they'd known it was an increasingly common scam.
You also need to hone your skills at verifying information, checking sources for reliability, and looking out for technical signs that what you're watching isn't right. These often include unusual facial movements or audio and video that seem mismatched.
Navigating the mountain of online content, help and advice related to health, exercise and diet online was a minefield at the best of times. Thanks to deepfakes, it's getting a whole lot tricker. But by understanding the threat and taking a few steps to help you establish fact from fiction, we can all help to protect ourselves and each other from harm.

Mom Notices Baby Has Birthmarks on Back, Then Comes Heartbreaking Diagnosis
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. What began as concern over birthmarks on her newborn's back unfolded into a journey of unexpected medical challenges for one mother online. In a TikTok video, mother Mackenzie Dodd summed up the whiplash of noticing something minor about her newborn baby, only to discover a shocking diagnosis. Dodd, 31, told Newsweek about her daughter's medical trajectory, and how she has had to adjust from typical parenthood to being a "medical mom"—that is, having a child with one or more medical complexities. "I wonder why she has so many birthmarks on her back," Dodd captioned the video of her newborn. "Spinal cord injury … Little did we know." Photos from Mackenzie Dodd's TikTok video of her baby. Photos from Mackenzie Dodd's TikTok video of her baby. @kenseacarolin/TikTok What initially appeared to be a cluster of birthmarks on her newborn's back was, in fact, a critical indicator of a significant spinal cord injury, launching Dodd and her family into the complex world of pediatric disability. Dodd recounted the earliest moments of her unease when her husband noted the birthmarks. "As soon as my husband glanced at me, I felt a pit in my stomach," she said. "He asked the nurses, and they assured us it seemed to only be birthmarks." Despite the initial reassurances, though, their gut feeling persisted. The gravity of the situation became clear as they prepared for discharge from the hospital. "We were getting ready to get discharged when the lead peds [doctor] decided she needed an ultrasound, which confirmed something wasn't 'right,'" Dodd said. "We then were told she needed to be transported to a bigger hospital an hour away. They did an emergency MRI and a neurosurgeon came in and told us the news. She was 1 day old when she got her diagnosis." The diagnosis revealed that her daughter had a spinal-cord injury. She suffered from Tethered Cord Syndrome, a neurological disorder where the spinal cord is abnormally attached to surrounding tissue. She also had Caudal Regression Syndrome, involving the abnormal development of the lower spine and spinal cord. This meant a future far different from what Dodd and her husband had imagined for their newborn. 'She Is Thriving' This unexpected journey profoundly reshaped Dodd's perspective on motherhood and health-care advocacy. "This journey has changed my perspective on motherhood completely," she said. "I have two older children that are neurotypical and never needed a doctor other than for checkups. It's given me a glimpse of the disability world—and being able to advocate, educate and push for inclusion has been so close to my heart ever since." Dodd's experience has fueled a deep commitment: "I urge any and every parent to advocate for their child's health," she added. Now 3 years old, Dodd's daughter continues to navigate her complex medical needs, yet thrives against the odds. "We are still learning all about her disability, and her future is still fuzzy, but she is thriving and doing so much better than doctors said," Dodd said. The family's life is marked by frequent medical appointments, sometimes over three per week. Despite the constant medical oversight, Dodd said that her daughter is, at her core, a typical toddler. "She is still a 3-year-old learning about the world, and it's so beautiful to see the relationship she has with her brothers, and seeing them protect and nurture that side of her as well," she said. This sibling bond is a highlight amid the challenges. Dodd documents her journey on TikTok as a "medical mom" sharing the importance of parental intuition and persistence in advocating for a child's health.

The 3 Stages Of 'Teen Separation', According To A Psychologist
A clinical psychologist has identified three stages teens go through when 'separating' from their parents – and it's resonating with a lot of people on social media. In a video shared on TikTok, Dr Lucie Hemmen said 'one of the most triggering things about teenagers is their separation process' from their parents, which often happens in a handful of stages (more on that in a moment). First of all, why do teens distance themselves from their parents? Adolescence occurs between the ages of 10 to 19 – it's the period between childhood and adulthood where tweens and teens experience 'rapid physical, cognitive and psychosocial growth', according to the World Health Organisation (WHO). As part of this, teens can begin pushing away from their parents, which adolescent therapist Ashley Hudson said is part of a typical developmental process. 'Teenagers want and subconsciously push for independence. Their biological clock ticks inside of them saying, 'Hey! You've got to figure out this adulting thing, because you are going to be on your own soon',' she explained. This might mean your teen is pushing back on boundaries, engaging in risky behaviours or simply spending more time with friends or romantic interests. This period is all about finding out who they are as a person outside of the family unit – and for parents, it's tough. The child you have nurtured and who might've idolised you for years all of a sudden doesn't want to know. What are the three stages of separation? Dr Hemmen said the first stage you might notice as your teen begins to pull away is disagreements. 'So a lot of times when a kid turns 13 or 14, their parent says: 'Oh my god, everything is an argument',' she explained. During arguments, the key advice for parents is to try and stay calm – as parental aggression is likely to be mirrored with teen aggression. The NHS advises ensuring your body language reflects your willingness to listen, and to give your teenager personal space during an argument. If things get very heated, don't be afraid to take time out. Explain you are going for a walk and will come back again in half an hour. The second stage of teen separation, added Dr Hemmen, is withdrawal. 'They often spend more time in their rooms because they're really craving independence,' she explained. This might also look like spending more time with friends. Again, teens withdrawing is a normal part of their emotional development – they're going off on their own, forming 'their own opinions, identity and values', according to psychologist Dr John Townsend. When this begins to happen, coaching site Reach Out urges parents not to take it personally – instead, keep an eye on your teen while also giving them the space and time to 'handle their own lives' (easier said than done, we know). Of course, sometimes withdrawal can be a red flag, which is why it's important for parents to avoid taking their foot completely off the pedal. If you're worried about your child, don't be afraid to be present, patient and share open-ended and emotionally neutral questions or statements like, 'I've noticed you seem quieter lately. That's totally OK, but I just want you to know I'm here anytime you want to talk'. (You can find more helpful, therapist-approved advice here.) Lastly, stage number three of teen separation is bending the rules and pushing the limits, according to Dr Hemmen. 'Let's face it, there's a spectrum. Some teenagers do this a little bit, some teenagers do it a lot. Obviously it's very triggering when they go way off road,' said Dr Hemmen. 'But the positive intention in that behaviour for teenagers is to explore the world and to think for themselves – and they often learn a lot about boundaries through crossing them and living with the impact of that.' Parents of teens are relating hard In response to the video, one parent wrote: 'I miss my sweet baby boy! Having a teenage boy is like trying to have a relationship with a guy that's not interested.' Their comment clearly resonated with a lot of people, as it had over 400 likes at the time of writing. Another said: 'I'm in stage 3 and I'm learning to walk a fine line of still parenting and letting my daughter grow up.' Making space for a teen's autonomy can clearly pay off in the long run though, as one parent commented: 'I learned that when I didn't push back, but openly encouraged and supported their autonomy and normalised and accepted their priorities and values being different than mine, they really matured.'

The Pink Salt Trick Recipe for Fast Weight Loss Trend in 2025: Why ProZenith Is the Science-Backed Alternative
Chicago, July 19, 2025 (GLOBE NEWSWIRE) — Disclaimer: This article is for informational purposes only. ProZenith is not intended to diagnose, treat, cure, or prevent any disease. Statements have not been evaluated by the FDA. Individual results may vary. Always consult a healthcare provider before beginning any supplement or diet strategy. Click Here to Explore the Full ProZenith Formula TL;DR: A trending pink salt recipe is sweeping TikTok as a supposed shortcut for weight loss. But what's really behind this viral drink, and why are experts raising concerns? In this report, we break down the trend's rise, the controversy around AI-generated celebrity endorsements, and how the new supplement ProZenith aims to support hormonal metabolism in a safer, research-backed way. In This Release, You'll Discover: What the 'Pink Salt Trick' recipe really is — and how it became a top 2025 TikTok trend Why AI-generated celebrity videos are being used to fuel misinformation The health risks of using saltwater as a weight loss tool What medical professionals and dietitians are saying about the trend Why women over 30 are most vulnerable to wellness misinformation How ProZenith compares biologically to salt-based hacks What makes ProZenith a better option for long-term metabolic balance Click Here to Learn More About ProZenith What Is the Pink Salt Trick Recipe Everyone's Talking About? The pink salt trick refers to a homemade drink recipe that's gone viral on TikTok and YouTube. It's typically presented as a 'weight loss drink' or 'morning metabolism hack' involving: The Recipe: 1/2 teaspoon pink Himalayan or Hawaiian salt Juice from 1/2 lemon 8–12 oz of warm or room temperature water Optional: 1 tsp apple cider vinegar or a dash of cayenne pepper The promise? Drink it first thing in the morning to 'reset metabolism,' suppress appetite, detox the body, and kickstart fat loss — without caffeine or fasting. Videos promoting the recipe often use phrases like: 'My pants are literally falling off!' 'This is what celebrities are using now.' 'Better than Ozempic!' But the science behind these claims is flimsy at best. And in many cases, entirely fabricated. Despite anecdotal praise, there are no peer-reviewed studies supporting the metabolic effects of pink salt water. Experts say any perceived benefits are likely due to placebo or temporary hydration effects, not real fat loss. The Deepfake Endorsement Controversy: Why the Internet Believed Oprah Promoted the Pink Salt Trick While the drink itself has gone viral, much of the attention in 2025 stems from AI-generated videos of Oprah Winfrey praising the recipe. These videos are so realistic that thousands believed they were real endorsements. In reality, Oprah never promoted the pink salt trick — and she condemned such deepfake scams in a 2022 Instagram video, stating: 'It is a fraud. It is a fake. It's a lie. I have nothing to do with any weight loss gummies or pink salt drinks that claim I use them.' Despite this, new videos using AI facial mapping and voice-cloning tools continue to circulate. Social media platforms have struggled to moderate these videos in real time, which has only contributed to their virality. This issue was spotlighted in Yahoo's creator series — What's Up with the Oprah Pink Salt Trick Recipe for Weight Loss? and What's the Deal with the Miracle Pink Salt Trick for Weight Loss? — where journalist Cassandra Brooklyn described how the fake endorsements kept showing up in her feed even though she never searched for weight loss tips. These articles were later mentioned in a broader industry discussion, including coverage in a GlobeNewswire consumer briefing on ProZenith. Read: Pink Salt Recipe for Weight Loss Spotlighted in New Consumer Briefing on Metabolic Reset with ProZenith Why the Pink Salt Trick Doesn't Work — and Might Be Harmful According to Dr. Alison Childress, a registered dietitian at Texas Tech University: 'Too much sodium can lead to water retention… this could result in weight gain — not fat, but fluid — especially in those who are salt-sensitive.' While the drink may provide a fleeting sense of fullness, there's no thermogenic benefit, hormonal regulation, or appetite suppression involved. Moreover, repeated use of this drink without iodine-rich salt can increase the risk of iodine deficiency, particularly among women of reproductive age. Iodine plays a critical role in thyroid hormone production, and inadequate levels can lead to fatigue, cold sensitivity, dry skin, and weight gain — all symptoms ironically counterproductive to the goals of the pink salt drink. Why Women Over 30 Are Most Vulnerable to These Trends Many women over 30 experience hormonal changes that affect metabolism, energy, and cravings. As stress levels increase and sleep quality declines, quick-fix trends feel even more attractive. Wellness journalist Cassandra Brooklyn explains: 'The pink salt videos started showing up in my feed even though I never searched for them. It made me wonder how many other women were seeing them too — especially those actively looking for help.' Research published in the International Journal of Behavioral Medicine shows that women exposed to 'rapid weight loss' messaging experienced higher body dissatisfaction and stress eating patterns. Compounding the issue is the algorithmic nature of social media, which can push diet content to vulnerable audiences based on a few clicks or likes. For women experiencing hormonal shifts and psychological stress, these seemingly innocent videos can drive harmful behaviors. Why ProZenith Was Formulated for This Exact Challenge ProZenith is a non-stimulant supplement formulated to help women manage appetite, cravings, and metabolic sluggishness without trendy hacks or viral gimmicks. What's Inside: Magnesium + Calcium – Regulate cortisol and stabilize energy – Regulate cortisol and stabilize energy BHB (Beta-Hydroxybutyrate) – Mimics ketone states to curb cravings – Mimics ketone states to curb cravings Turmeric Extract (95% curcuminoids) – Supports inflammation reduction – Supports inflammation reduction BioPerine® – Enhances nutrient absorption and delivery Unlike the pink salt trick, ProZenith doesn't rely on a placebo effect.

Explore the Full Ingredient Breakdown Read: ProZenith Ingredients Researched: The Science Behind the Popular Formula Final Thoughts: Why This Trend Matters More Than It Seems The pink salt trick may look harmless. But it reflects a deeper pattern: emotional marketing, AI misinformation, and health shortcuts with no science behind them. ProZenith doesn't promise overnight results.
