Number 1: Can You Build Muscle While Losing Fat? The Science of Body Recomposition
Vanessa breaks down the biggest takeaways from her conversation with Dr. Sara Oikawa, including what the research says about losing body fat while preserving—or even gaining—lean mass. A major focus is a tightly controlled body recomposition study in which young men followed a 40% calorie deficit while completing intensive resistance and interval training. The group consuming 2.4 g/kg of protein per day actually gained lean mass while losing fat, while the lower-protein group maintained lean mass. Vanessa explains why resistance training was likely the most important signal, how higher protein intake may support muscle preservation during a deficit, and why body recomposition depends on much more than calories alone.

Vanessa also recaps Dr. Oikawa's step-reduction research, where older adults reduced their activity to just 750 steps per day. Even while consuming a high-protein diet, participants still lost lean mass—highlighting why protein cannot completely replace the stimulus of muscle contraction. Another major focus is protein quality. Vanessa breaks down research comparing whey protein isolate and collagen peptides, why they do not produce the same muscle protein synthetic response, and why simply counting total grams of "protein" may not tell you whether you are getting enough essential amino acids to support muscle. They also explore how aging, energy availability, periods of inactivity, illness, surgery, and aggressive calorie restriction can influence muscle loss and recovery. 🥤 True Nutrition Create your own custom protein blend at truenutrition.com/vanessa and use code VANESSA for 20% off your first order.

Number 2: Eat More Protein, Lose More Fat? The Surprising Science of Body Recomposition: Dr. Cassandra Evans
Dr. Cassandra Evans joins Vanessa to break down the science of protein, body recomposition, fat loss, muscle preservation, genetics, caffeine, and women's iron health. BACK TO SCHOOL SALE!

Australia, New Zealand & Southeast Asia: Save 75% on available ToneLUX and Tone products during the warehouse moving sale with code WAREHOUSE75, while supplies last. They discuss how much protein may be optimal during body recomposition and fat loss, including research showing that higher-protein diets can help preserve lean mass, improve satiety, and in some cases even support muscle gain while losing body fat. Cassandra also shares fascinating protein-overfeeding research suggesting that increasing calories from protein may affect body composition very differently than overfeeding on fat or carbohydrates. They break down the myth that high-protein diets are harmful to bone health, including research in resistance-trained women, and explore the FTO "obesity gene," how it may influence hunger and food intake, and why exercise appears to reduce some of the differences associated with genetic risk.

Vanessa and Cassandra also discuss caffeine and energy drinks, why caffeine appears to be doing most of the heavy lifting for performance and cognition, and common myths around caffeine and hydration. They finish with Cassandra's emerging research on lactoferrin and iron status in women, including how lactoferrin may influence hepcidin, iron utilization, gut health, pregnancy, postpartum health, and menopause. In this episode: How much protein do you need for body recomposition? Can you gain muscle while losing fat? How protein helps preserve lean mass during a calorie deficit Why higher protein may support greater fat loss What protein-overfeeding studies reveal Why resistance training is critical during fat loss Are high-protein diets bad for bone health?

Number 3: Do You Really Need 10,000 Steps to Lose Fat? The Science of Walking & Body Recomposition: Dr. Amanda Paluch
How many steps do you actually need every day—and do you really need 10,000 steps to support fat loss, health and body recomposition? BACK TO SCHOOL SALE!

Australia, New Zealand & Southeast Asia: Save 75% on available ToneLUX and Tone products during the warehouse moving sale with code WAREHOUSE75, while supplies last. In today's episode of the Optimal Protein Podcast, Vanessa sits down with physical activity researcher Dr. Amanda Paluch to unpack what the science really says about daily steps, walking, energy expenditure, appetite, fat loss and longevity. One of the biggest surprises? The famous 10,000-steps-per-day goal was not originally based on scientific research. Vanessa and Dr. Paluch dive into what the latest research actually suggests about optimal daily step counts, why benefits can occur well below 10,000 steps, and how walking can fit into a smart body-recomposition strategy.

They also explore why adding more activity does not always lead to the amount of weight loss we might mathematically expect, how the body can compensate for increases in energy expenditure, and why low levels of daily movement may affect appetite regulation and fat gain. In this episode, they discuss: • Where the 10,000-steps-per-day recommendation actually came from • Whether 10,000 steps is really necessary • How many daily steps are associated with meaningful health benefits • Why the ideal step target may differ depending on age • Whether benefits continue increasing beyond 10,000 steps • Why increasing steps from a very low baseline may provide especially large benefits • Walking and daily energy expenditure • How increasing daily movement can support fat loss • The role of steps during a body-recomposition phase • Why exercise sometimes produces less weight loss than expected • Energy compensation and how the body responds to increased activity • Whether increased exercise can influence appetite and food intake • The relationship between sedentary behavior, appetite regulation and fat gain • NEAT and why movement outside of formal workouts matters • Whether walking speed matters as much as total step count • Step volume versus exercise intensity • Whether sitting less matters even if you already exercise • Why walking and resistance training serve different purposes for body composition • Whether you need to hit the same step target every day • Simple, realistic ways to increase daily movement without adding another formal workout If your goal is to lose body fat while preserving or building metabolically active muscle, this episode breaks down one of the simplest and most accessible tools available: walking. And perhaps most importantly, you do not need to be perfect or hit an arbitrary number every single day. Moving from less activity to more activity can be incredibly meaningful—and the biggest gains may come simply from getting off the lowest end of the activity spectrum. BACK TO SCHOOL SALE!
