Recalibrate your composition
Sustainably lower body fat & support muscle
The Body Recomposition Masterclass is a science-forward guide for women ready to finally build the body underneath the number, not just chase the scale, and reclaim lasting strength and metabolic health. Blending endocrinology, energy balance, and the physiology of fat loss, it invites you into a precise, practical understanding of your metabolism, your muscle, and your whole body entirely on your own terms.

What You Will Learn
Understanding Body Composition
It has never about the number on the scale. Discover what your body is truly made of, the difference between fat mass and lean muscle, where fat sits and why visceral fat matters most, and why two women of the same size can have completely different health. This is the foundation that reframes everything: composition, not weight, is what shapes how you look, feel, and function.
The Systems Beneath the Surface
Weight isn't governed by willpower, but by physiology. Journey through the hormones and systems that quietly run the show: insulin and appetite, the thyroid and adrenals, the gut and its microbiome, and how sleep and stress shape it all. Understand why a body under strain resists fat loss, and how these systems can be brought back into balance to work with you rather than against you.
Energy, Deficits & Metabolism
Learn how your body actually spends energy, how to find your real daily needs, and how to build a deficit that lasts. Discover why aggressive dieting backfires through adaptive thermogenesis, how to protect your metabolism as you lose fat, and how to come out of a deficit without regaining everything. This is sustainable fat loss, built on how metabolism truly works.
Building & Keeping Muscle
Muscle is the engine of recomposition. Explore how muscle is built through training and protein, why lean mass raises your metabolic rate and clears glucose, and how to preserve it while losing fat. From resistance training to protein targets to the science of muscle protein synthesis, learn to build a body that is stronger, leaner, and metabolically resilient for the long term.
Nutrition That Works With You
Turn the science into what actually goes on your plate. Discover how to build meals across the day to support muscle and fat loss, from breakfast through to dinner, snacks, and training nutrition. Learn the role of protein, carbohydrate, and fat, how timing supports your goals, and how to eat in a way that is sustainable, satisfying, and entirely your own.
