Transforming Health through Pro-Metabolic Nutrition with Kitty Bloomfield and Craig McDonald

December 17, 2025·1 hr 8 min·4 clips

Craig says an improving sleep, digestion, mood, energy, cycle, and body composition profile outweighs one high LDL number.

The episode starts with a little backstory before the nutrition argument really takes off. The host says he had been following Kitty Bloomfield for years, tracing that back to an employee mention from four years earlier, so the conversation has a long-awaited feel. Craig McDonald is in the mix too. The pair settle into a talk about restrictive dieting and how long stretches of trying to get smaller and leaner can shape the way someone thinks about health. Kitty says she is nearly 45, which gives the story a grounded, lived-in edge. From there, the conversation moves into pro-metabolic nutrition, framing food as fuel for energy and hormones rather than a moral test. LDL comes up hard. The discussion argues that the number needs context, because health is not one neat box and the same marker does not tell the whole story for everyone. Carbs get defended too. One speaker says his LDL has been going down as he eats more carbs, and the episode widens into the larger point that the body needs cholesterol, T3, vitamin A, and the raw material for pregnenolone, progesterone, and DHEA. That hormonal chain matters, especially in the estrogen-dominance conversation the guests keep circling. The point is that skipping the basics can leave people underfed and underpowered even when their habits look disciplined. There is also some gentle pushback toward the keto crowd. Not everyone who insists LDL does not matter is necessarily healthy, and the episode leaves that tension in place instead of smoothing it over. The tone stays loose and opinionated. It moves the way this show likes to move, with banter opening the door and a blunt thesis waiting in the hall. By the end, the message is simple and direct: enough energy, enough nutrients, and a body that feels like it can actually run. The conversation is clearly trying to persuade, using personal experience, mechanism talk, and a lot of confidence. Listeners who want a skeptical, nutrition-culture argument with some swagger will know why this one lands.

As heard by us

A firm case for eating enough, not less.

The episode traces Kitty Bloomfield's move from years of restrictive dieting and a wish to be small and lean into a wider conversation about carbs, cholesterol, LDL, and the role of enough energy and nutrients in hormonal health.
