Why can two people follow the same weight loss plan and get completely different results?

In this episode of the All or Something Podcast, we dive into the science of interindividual variability and explore why some people find losing weight and body fat much harder than others.

We discuss the research showing that people can respond very differently to the same diet, exercise program, or lifestyle intervention. From differences in appetite and hunger to energy expenditure, genetics, behaviour, and biology, we break down the many factors that influence weight loss outcomes.

Topics covered include:

- Why average results can be misleading
- Individual differences in fat loss and weight loss
- Appetite, hunger, and food cravings
- Genetics and biological variability
- Metabolic adaptation and energy expenditure
- Why some people are 'compensators' and some are not

If you've ever wondered why weight loss seems easier for some people than others, this episode is for you.

Women's health is one of the most discussed topics in fitness, and one of the most misunderstood.

In this episode, we sit down with women's health specialist Sheridan Skye (sheridanskyefit on Instagram) to examine some of the most common claims surrounding exercise, hormones, menstrual cycles, pregnancy, and menopause.

We discuss whether women need to train differently during different phases of their menstrual cycle, what the research actually says about exercise during pregnancy, common misconceptions about menopause, and why so many strongly held beliefs continue to spread despite limited evidence.
Topics include:

- Training around your menstrual cycle
- Hormones and exercise performance
- Exercise during pregnancy
- Pregnancy myths and misconceptions
- Menopause and fitness
- Women's health misinformation
- What the evidence actually says
- Why social media often gets these topics wrong

Whether you're a coach, healthcare professional, or simply someone trying to make sense of the conflicting information online, this episode aims to separate evidence from assumption.

You sent in your questions, and we answered them.

In this episode, we're doing something a little different and stepping away from our usual deep dives into nutrition, weight loss, fitness myths, and research. We asked for your questions on Instagram, and we gave no specifications on what they needed to be. This was essentially an "ask us anything".

We received a lot of questions and coincidentally, about 80% of them were to do with our baby (apart from the odd one about whales, trees and sandwiches!).

We didn't expect the Q&A to take that direction, but we're glad it did.

Although this episode was a different change of direction, it was actually really enjoyable for us because we like the idea we can talk to you about personal things, and it is also nice just answering your questions because it feels a little bit more like we are having this conversation in person, rather than over the internet.

So, yes. This is a very different change of pace, but we hope you like it!

Fat shaming is often defended as "motivation," "accountability," or simply "telling the truth."

But does it actually help people improve their health? Does fat shaming encourage people to exercise more, eat less food, and eventually have a healthy and happy life?

In this episode, we take a deep dive into the research on weight stigma, fat shaming, and health outcomes. We discuss the difference between talking about health and humiliating people, the psychological effects of shame, weight stigma in healthcare, and whether public criticism of body size encourages or discourages healthy behaviors.

We also explore:
- What weight stigma actually is
- Whether shame motivates long-term change
- The impact of weight stigma on eating behaviors
- Weight stigma in healthcare settings
- Social media, fitness culture, and body judgment
- Why this topic is so emotionally charged

It is possible to discuss health, and even negative health risks, without having to resort to insults and bullying.

As always, our goal is not to take an ideological position, but to examine what the evidence actually shows.

BMI (body mass index) is one of the most controversial tools in health and fitness.
Some people say it’s outdated, inaccurate, and harmful. Others argue it’s still one of the most useful population health tools we have.

So… who’s right?

In this episode, we break down:
- where BMI came from
- what it was originally designed for
- what BMI actually measures
- whether BMI is useful for individuals
- why athletes and muscular people complicate the conversation
- how BMI relates to disease risk and mortality
- the biggest misconceptions about BMI
- weight stigma and the ethics of discussing body weight
- whether BMI should still be used in healthcare today

We also discuss how social media has shaped the BMI debate — and why many online conversations oversimplify both the science and the criticism.

This is not a “BMI is perfect” episode.
And it’s not a “BMI is meaningless” episode either.

As usual, we aim for nuance over outrage.

We hope you like it.

Alcohol is one of the most widely consumed substances in the world, but the science around it is more confusing than most people realise.

In this episode, we break down what the evidence actually says about alcohol, fat loss, appetite, muscle retention, and of course, a big disclaimer about health.

We also discuss:
- Why alcohol research is so difficult
- The problems with observational studies
- The “red wine is healthy” narrative
- Drinking culture
- Dose-dependent risk

As always, the goal is objective and nuanced discussion, not exaggerated black and white views. Whilst we are absolutely not encouraging alcohol intake, we think it is a good idea for you to understand what the research actually says.

We are back from our break, and it gives us great pleasure to introduce you to our baby.

(For privacy reasons, we are not showing her face or telling the world her name. The thumbnail is a stock photo and not of her, because some people on the internet can be creepy).

In this episode, we answer the questions everyone wanted to ask us about childbirth, postpartum recovery, and the first few weeks of parenthood.

We talk about:
- pain relief
- epidurals
- sleep deprivation
- tearing
- postpartum depression
- life with a newborn

Plus all the gross and emotional stuff that you would expect from an unfiltered episode.

We also share parts of the birth experience, what surprised us most, and the things nobody fully prepares you for before becoming parents.

This is our most sleep-deprived episode yet. We hope you like it.

This episode is a little different from our usual ones.

With our baby about to arrive, we wanted to take a moment to sit down and talk very candidly about how we’re feeling right now. The excitement, the nerves, the uncertainty, and the reality that life as we know it is about to change in a big way. Please note that we recorded this episode a few weeks ago, but planned to release it right around her due date.

We’ve spent a lot of time on this podcast talking about fitness, health, and evidence-based topics, but this felt like an important moment to share something more personal. Not because we have all the answers, but because we wanted to let you in on where we’re at before stepping into this next chapter.

In this episode, we talk about:
- What this transition into parenthood feels like for us
- The mix of emotions that comes with such a big life change
- How we’re thinking about what comes next
- Why we felt it was important to record this before she arrives

If you’ve been listening to the podcast, thank you for being here. It genuinely means a lot to us, and we don’t take that for granted.

This episode might mark the beginning of a hiatus for us. If that happens, we are not sure how long it will last, but wanted to let you know in advance.

Thank you for all of your support.
