The Metabolic Mistake Killing Your Energy

The Randle Cycle Explained

There’s a reason you feel tired after eating. Even if your food is clean.

And it’s not about calories or macros.

It’s about the Randle Cycle.

What’s the Randle Cycle?

The Randle Cycle is your body’s internal fuel switch.

It determines whether you burn fat or carbs for energy.

Unfortunately, you can’t burn both efficiently at the same time.

When you eat a high-fat, high-carb meal…

(Think ribeye and baked potato or eggs with buttered toast)

You create a metabolic traffic jam.

Fat tells your body to burn fat for energy.

Carbs tell your body to burn carbs for energy.

The fats in your meal slow your gut transit (how quickly food is digested) and the carbs spike your insulin—making you tired.

Then, your body decides what fuel to burn depending on what your body is used to burning. This is determined by your metabolic health and genetics.

For these reasons, it is generally not a good idea to eat a high-fat, high-carb meal.

You are more likely to gain fat and feel sluggish afterwards.

The Simple Fix

Pick one—keep either fat or carbs below 20% of your daily calories.

  • If you’re eating high-fat? Keep carbs low.

  • If you’re eating high-carb? Keep fats low.

Or, simply choose on a per-meal basis. When you eat high-carb, don’t consume much fat, and vice versa.

This lets your metabolism pick a lane — and your body will thank you for it.

You’ll feel more energized, have stable blood sugar, and feel light throughout the day.
