Scroll through TikTok or Instagram for five minutes and you'll find someone telling you exactly how to lose weight, build glutes, or "fix" your metabolism. They're confident, they're on camera, and they've got the abs to prove it. But looking good on camera and knowing what they're talking about are two very different things — and mixing the two up can cost you time, money, and sometimes your health.
Here's how to enjoy fitness content without falling for the nonsense.
Why Influencers Aren't Always Reliable
Anyone can pick up a phone and call themselves a coach. There's no qualification needed to post a workout video, and algorithms reward content that's dramatic, extreme, or emotionally charged — not content that's accurate. A calm, evidence-based explanation of progressive overload will never get the views that "I lost 10kg in 10 days doing THIS" will.
That means the loudest voices in your feed are often loud because they're extreme, not because they're right.
Common Fitness Misinformation to Watch For
"Detox" teas, drops, and juices
Your liver and kidneys already detox your body. No tea speeds that up — most of these products just cause water loss or a laxative effect, which isn't fat loss.
Extreme, rapid results promises
Sustainable fat loss sits around 0.5–1% of bodyweight per week. Anything promising far more, far faster, usually involves muscle loss, water manipulation, or an unsustainable crash that leads to rebound weight gain.
"This one exercise will target your lower belly fat"
Spot reduction isn't real. You can't choose where your body loses fat from through specific exercises — that's determined by genetics and overall body fat percentage.
Fearmongering about "normal" foods
Carbs, dairy, gluten, seed oils — plenty of influencers build entire followings around demonising an everyday food group. For the vast majority of people, without a diagnosed intolerance or allergy, these foods are perfectly fine as part of a balanced diet.
Miracle supplements
If a supplement claim sounds too good to be true — melts fat, builds muscle overnight, "hacks" your hormones — it almost always is. Most supplements have modest effects at best, and many aren't tested for safety or dosage accuracy at all.
The Sneaky Sales Tactics to Look Out For
The "problem, then product" formula — a video convinces you something is wrong with your body or routine, then conveniently offers the fix in the caption or a discount code.
Fake urgency — "link in bio, offer ends tonight" is a pressure tactic, not a real deadline.
Before-and-afters without context — lighting, posing, pumps, dehydration, and even different camera angles can create dramatic "transformations" in minutes, not months.
Undisclosed partnerships — always check for #ad or #gifted. If it's missing but the product happens to be mentioned in every third video, that's worth questioning.
Manufactured relatability — "I struggled just like you" builds trust quickly, but trust isn't the same as expertise.
How to Check If Advice Is Actually Worth Following
1. Check their qualifications. Are they a certified PT, registered dietitian, physiotherapist, or similarly qualified professional? A bio full of buzzwords isn't a qualification.
2. See if the advice matches consensus. If NHS guidance, major health bodies, or numerous qualified professionals disagree with a claim, be sceptical of the one person saying otherwise.
3. Watch the language. Words like "hack," "secret," "melt," "detox," and "one weird trick" are marketing language, not scientific language.
4. Ask what they're selling. If the advice conveniently leads to a product, program, or affiliate link, factor that bias into how you weigh it.
5. Look for nuance. Good advice usually comes with caveats — "this depends on your goals," "this isn't right for everyone." Absolute, one- size-fits-all claims are a red flag.
6. Cross-check before changing your routine. A quick search against reputable sources, or a conversation with a qualified coach, takes two minutes and can save you months of wasted effort.
Fitness content can be brilliant for motivation and ideas — but treat it as entertainment first, education second. Anything that could affect your health, your training programme, or your wallet deserves a second look before you act on it.
