Why Methane SIBO Causes Weight Gain (Even When Eating Less)

Send us Fan Mail

Have you ever looked at your plate and thought, “I’m eating less than ever… so why is my weight going up?” If you’ve tried low-FODMAP, cut sugar and carbs, cleaned up your diet, and somehow feel heavier, slower, and more inflamed, this episode is for you.

In this episode, Alyssa dives into one of the most confusing and overlooked patterns in gut health: why some people with SIBO experience weight gain instead of weight loss, and why everything you’ve been told to do might actually be working against you. Alyssa explains why not all SIBO behaves the same, and how a specific subtype can quietly change how your body handles food, energy, and inflammation.

You will learn:

• Why common SIBO advice often doesn’t apply to this pattern
• What it means when your body seems to “hold onto” weight
• Why digestion can feel heavier and more reactive the harder you try
• Where diet helps, and where it can quietly backfire
• What needs to be addressed for real progress to happen
