It's Not About the Six-Pack (Why We Started This)

You've just finished a big meal and you're completely stuffed. So why is there always room for tiramisu?In this episode, brothers Laz, a doctor, and Lahiru dig into the science of hunger: why it exists, how your brain decides when you need to eat, and why it isn't just one feeling. We break down the three types of hunger (homeostatic, hedonic and conditioned), explore how our five tastes evolved as a food-screening system for hunter-gatherers, and explain why the modern food environment is so good at hijacking all of it.We also get honest about our own weak spots, from stress-eating chocolate to a serious chocolate finger habit, and share practical ways to work with your biology instead of fighting it.Plus: why "hangry" might be real, what food noise is, and a simple challenge to try this week.

Every January, millions of us stand in front of the mirror and declare this the year everything changes. By the end of the month, most of us have quietly given up.This episode, we break down why. The problem isn't willpower, and it isn't the goal itself. It's that most of us try to build an elaborate staircase over the wall standing between us and the habit we want, when what actually works is picking up a sledgehammer and clearing the obstacle entirely.We get into why professional athletes' "big goals" are misleading if you copy the goal without the routine underpinning it, how Lahiru rebuilt his entire exercise routine around removing guilt rather than finding motivation, and how Laz's reading of Ultra-Processed People rewired his relationship with food almost overnight. We also cover the "1 > 0" principle, why tracking progress can be genuinely addictive in a good way, and where the line sits before healthy habits tip into something less healthy.If you've ever written a resolution you didn't keep, this one's for you.Move. Rest. Eat.

You don't grow in the gym — you grow in your sleep. In this episode, we break down what's actually happening physiologically when you train, and why the real muscle-building work only starts once you put the weights down.We cover why muscle protein synthesis stays elevated for up to 48 hours after a hard session, why sleep specifically (not just general "rest") plays such an outsized role thanks to growth hormone release during deep sleep, and what actually happens if you skip recovery and stack heavy sessions back to back - spoiler: it's not extra gains, it's a fast track to overtraining and injury.We also touch on something most people never connect to their training: diet. Specifically, how a diet high in ultra-processed food can quietly undermine the very sleep you need to recover, through nutrient deficiencies that disrupt melatonin production and blood sugar swings that mess with hormone signalling overnight.If you've ever wondered why two people can train identically hard and get completely different results, this episode is the missing piece.

Walk into any supermarket and protein is everywhere: high-protein yoghurt, high-protein cereal bars, even high-protein beer. The message is that you need more of it and the more the better. But what does protein actually do, how much do you really need, and why has the ultra-processed food industry suddenly fallen in love with it?Laz explains what protein is beyond muscle, turns "grams per kilogram" into what it looks like on a plate, and why the extra doesn't just get stored as muscle. Lahiru asks the questions everyone's thinking: does the fat that comes with it matter, what if you're eating more plant-based, and does it matter when you eat it? Along the way: why protein has had a clean run while fat and carbs took turns as the villain, whether a protein bar is better than a KitKat, and why "high protein" on a label should make you more suspicious, not less.This week's challenge: pick one or two whole-food protein sources and batch-cook it.Move Mindfully. Rest Intentionally. Eat Real Food.

Growing up in Sri Lanka, Arnold Schwarzenegger was the blueprint -muscle meant vanity.Two decades of lifting weights and one medical degree later, we know better: muscle is a modifiable organ, and what it does for your body, your brain, and your future is what really matters.We talk sarcopenia, the crooked nail applied to muscular imbalance, why South Asians in particular are at risk, and how we each actually fit strength training into wildly different, chaotic lives.Move. Rest. Eat.

Two brothers, one shed, and the honest story of why we started Fit Between. We talk shift work vs. structure, the crooked nail theory of movement, and set our first challenge - squats before brushing your teeth.
