Your fitness activity tracker probably isn't fully trustworthy and the science backs it up.

In this episode, we dig into the research on fitness activity tracker (smart watch) accuracy, diving deep into the research especially for the Apple Watch, Fitbit, Garmin and Oura Ring.

From step counts and heart rate monitoring to calorie burn and sleep tracking, we break down what the data actually says, and the results might surprise you.

Whether you're training for a race, trying to hit 10,000 steps, or just wondering if your tracker is giving you the full picture, this episode is for you.
What we cover:

- How accurate are Apple Watch, Fitbit, Garmin and Oura Ring really?
- Which metrics are most (and least) reliable.
- What the latest research says about wearable accuracy.
- Should you trust your tracker's calorie and heart rate data? If not, how big is the margin of error?

Perhaps most importantly, does it matter if smart watchers and fitness activity trackers aren't fully accurate? Maybe that doesn't matter.

In this episode, Sohee and Ben sit down for a candid (and occasionally exposing) relationship Q&A in which nothing is off limits.

We kick things off with a rapid-fire round of “Who’s more likely to…” — from who apologizes first after an argument, who’s more likely to spend money, who stays calm in an emergency, and more.

Then we zoom out into the bigger stuff.

We share how we met, how quickly we knew this was it, and the small, everyday habits that actually keep our relationship strong. We talk honestly about balancing being business partners and romantic partners, how we divide labor at home, and when we knew we wanted to become parents.

The final stretch gets deeper:
What would actually be a deal breaker?
Is there anything from our past that still impacts us today?
What scares us most about our relationship?
What makes each of us feel especially loved?

If you’re in a relationship, curious about our dynamic, or simply enjoy hearing how couples actually work through things — this one’s for you.

Is 10,000 steps per day actually necessary for good health?

In this episode, we break down where the 10,000-step target came from (including the Japanese marketing origin story), what the scientific research really shows, and whether more steps always mean better health.

We cover:
- Where the 10,000 steps idea started
- What large cohort studies show about steps and mortality
- The dose–response relationship between steps and health
- Whether intensity matters more than total steps
- How many steps are “enough” for most people
- The difference between fat loss goals and longevity outcomes
- Whether 10,000 is optimal… or just a nice round number

If you’ve ever felt guilty for not hitting 10k or assumed it was the gold standard, this episode will give you a clearer, evidence-based perspective.

As always, we focus on nuance over extremes and data over dogma.

Ultra-processed food is being blamed for everything from obesity to heart disease. But is it really that simple?

In this episode, we break down what “ultra-processed food” actually means, where the term comes from, and what the scientific evidence really says. We discuss the NOVA classification system, the research linking ultra-processed food to chronic disease, and the well-known randomized controlled trial led by Kevin Hall at the National Institutes of Health, amongst other newer research papers.

But we also explore the nuance.

- Are all ultra-processed foods equally harmful?
- Is processing itself the problem — or are other factors at play?
- And could “ultra-processed” be an oversimplified label for a much more complicated issue?

We talk about:
- What counts as ultra-processed food (and what surprises people)
- The strongest evidence linking UPFs to weight gain and disease
- The limitations of observational nutrition research
- Whether bread deserves the same label as soda

If you’re confused by the headlines or tired of nutrition being reduced to good vs bad, this episode is for you.

In this episode of the All or Something Podcast, we share 10 practical ways to lose weight and improve your health—without dieting.

If you’re tired of restrictive diets, obsessive calorie counting, and feeling like weight loss and health improvements always have to be a miserable journey, this episode is for you.

We break down what actually matters for long-term results, focusing on habits, behaviours, and health markers instead of short-term scale changes.

We talk about:
- Why dieting often backfires
- Habits that highly successful dieters tend to use
- Simple behavior changes that can improve health and body composition
- What to focus on if your goal is sustainability, not quick fixes

This episode isn’t about overly strict rules, meal plans, or cutting out entire food groups. It’s about building a healthier lifestyle that could support weight loss as a side effect, rather than being the sole objective.

Whether your goal is fat loss, better energy, improved health, or improve your relationship with food, these ten tips could help.

Do 95% of diets really fail?

The claim that “95% of diets fail” is everywhere — but is it actually true?

In this episode of the All or Something Podcast, we break down where the 95% statistic comes from, why it’s often misunderstood, and what modern research really says about long-term weight loss success.

While long-term weight loss outcomes can be challenging, the idea that diets universally “fail” is an oversimplification based largely on outdated research.

We explore how weight loss "success" is defined in studies, why weight regain is common, and what this means for people trying to make sustainable changes without shame, fear, or diet culture myths.

If you’ve ever felt like weight loss “never works,” this conversation will help you understand the science more clearly — and more compassionately.

In this episode, we discuss:

- Where the “95% of diets fail” claim originated
- Why long-term weight loss success rates are often misrepresented
- What newer research tells us about weight regain
- Why framing matters when talking about weight loss and health

This episode is for anyone confused or frustrated by conflicting weight loss advice, and for those who want a more nuanced, research-informed conversation.

In this episode, I (Ben) share my background and how I ended up working in the fitness industry, from becoming a personal trainer to finding my voice online.

We talk about why I’m passionate about discussing mental health, outwardly supporting women (without excluding men lol), why I don’t believe fat loss is easy or achievable in the same way for everyone, and why I think large parts of the fitness industry feel unwelcoming, exclusionary, and often harmful.

I also open up about:

• What I strongly disagree with in the fitness industry
• Things I have said that have annoyed people online, and why I think they are often wrong about me
• My own experiences with mental health, and why I’m so outspoken about mental health issues in fitness

This episode is about what I stand for, who this podcast is for, and why I believe fitness needs to do better — especially for people who feel like they don’t “fit” the typical mould.

If you’ve ever felt confused, blamed, or pushed aside by fitness culture, this episode is for you, and is the final part of the series where you get to know us as your hosts, before we move onto specific health, fitness and nutrition topics.
