Summary
On episode 94 of 40+ Fitness, Coach Allan breaks down elimination diets: what they are, why they work, and how to use them to rebuild your gut health after years of eating foods that quietly cause problems.
His core argument: many everyday symptoms, like brain fog, indigestion, and low energy, are actually low-grade reactions to specific foods that we've just learned to live with. An elimination diet removes the likely culprits (sugar, gluten, dairy, eggs, artificial ingredients, and processed foods) for 28 days or longer so the gut microbiome can reset.
He also lays out how to reintroduce foods one at a time afterward, tracking how each one affects energy, mood, and digestion, so you end up with a personal blueprint of what your body can and can't handle.

Key Takeaways
- An elimination diet exposes food sensitivities you don't know you have. Symptoms like indigestion, brain fog, or low energy often build up so slowly that they feel normal. Removing likely trigger foods for a set period lets you see what “normal” is supposed to feel like.
- Your gut microbiome drives cravings, not just willpower. When you cut out something like gluten, the bacteria that thrived on it start dying off and send signals that show up as cravings. Pushing through that phase, not giving in to it, is part of the process.
- The standard elimination window is about 28 days, but Allan recommends going longer. Four weeks is usually enough to break cravings, but issues like leaky gut may need more time to fully resolve.
- What gets eliminated is mostly processed food, not real food. Sugar, gluten, dairy, eggs, artificial sweeteners, flavorings, and processed foods come out. What's left is vegetables, meat, and, for some people, dairy: real food, not a restrictive punishment.
- Herbs, spices, and variety keep the diet from feeling bland. Allan argues you can eat well within the restrictions by mixing textures, spices, and simple combinations like kale, peppers, and chicken or seafood.
- Reintroduce foods one at a time, not in groups. Adding two foods back at once makes it impossible to know which one caused a reaction. Allan's approach: pick the food you want most and are least likely to react to, add a small amount, and track how you feel for several days before moving to the next.
- Some foods should never go back in. Processed food, sugar, and artificial sweeteners aren't real food to begin with, so there's no reason to reintroduce them after the reset.
- A healthy gut can tolerate occasional slips. Once your gut microbiome is rebuilt over months of clean eating, an occasional treat, like a homemade holiday cookie, won't send your body into a tailspin the way it would when you were already inflamed.
- You don't have to feel sick to benefit from an elimination diet. Allan says even people who think they feel fine often discover, after 28 days, that they feel noticeably better, which is reason enough to try it.
