Most people who try to lose weight and keep it off end up failing. But what if the problem isn’t you - it’s the diet?In this episode, we cut through the noise of weight loss fads to explore a science-backed method that’s helped countless people make real, sustainable changes. It’s called flexible dieting, and it’s built around the idea that personalised macronutrient targets, food quality, and consistency matter more than restrictive rules or trendy plans.Our guest is Alan Aragon, a leading expert in fitness nutrition who’s spent over 30 years coaching clients and publishing research that’s reshaped how the industry thinks about fat loss. Alongside Alan is Professor Sarah Berry, ZOE’s Chief Scientist, who brings insight from her studies on metabolism and how our bodies respond to food.Together, they unpack what actually works for long-term fat loss — and how you can get started with a realistic, effective approach that doesn’t require cutting out the foods you love.Unwrap the truth about your food 👉 ⁠Get the ZOE app 🌱 Try our new plant based wholefood supplement - Daily 30+*Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune systemFollow ZOE on Instagram.Timecodes📚Books by our ZOE ScientistsThe Food For Life CookbookEvery Body Should Know This by Dr Federica AmatiFood For Life by Prof. Tim SpectorFree resources from ZOELive Healthier: Top 10 Tips From ZOE Science & NutritionGut Guide - For a Healthier Microbiome in Weeks Mentioned in today's episode Resistance Training Combined With Diet Decreases Body Fat While Preserving Lean Mass Independent of Resting Metabolic Rate: A Randomized Trial Effects of meal frequency on weight loss and body composition: a meta-analysis Does Timing Matter?
