If you want to lose weight this New Year and actually keep it off, this episode will change how you think about fat loss.

In this episode of Performance That Matters, Jordi sits down with Jack (The Combat Dietitian) to break down why most New Year weight loss attempts fail and what actually works long term.

This isn’t about crash dieting, extreme restriction, or “perfect” eating.
It’s about habit formation, structure, environment, and self-awareness, the same principles we use with elite athletes and everyday clients who get sustainable results.

You’ll learn:

Why habit formation matters more than calories at the start

How chasing perfection leads to burnout and rebound weight gain

Why most people underestimate how much they actually eat

How to eat well when travelling, working long hours, or under stress

The real reason restrict–binge cycles happen

How sleep, hydration, stress, and lifestyle affect fat loss

Why there is no finish line when it comes to weight loss

The exact first step we give paying clients to set themselves up for success

If you’re sick of starting over every January, this episode will give you a framework you can use for life.

In this episode, Jordan Sullivan, Performance Dietitian to Elite Athletes and High Performers, and Director of World Renowned Performance Nutrition Company, TFD (The Fight Dietitian), discusses everything you need to know about figuring out how many calories you need to adequately fuel your body.

The discussion begins with a review on what exactly a calorie is, how the calorie was introduced to science, how our body extracts calories from food, what our body uses energy for, how energy needs differ between individuals, the warning signs you are getting it wrong and how to put all of this together to use equations, multipliers and a tracking system to make sure you are fuelling your body properly.
