Like, water has no calories. But plants do? And some random elements have like billions of calories but if you just pick up a rock and eat it you won’t get any energy.
In: Biology
Plants are carbs but we can’t digest them, our gut microbiome does. So we absorb minimal calories from these.
But it’s important to eat plants because the gut microbiome biome is responsible for 70% of our immune, mood and metabolism.
Some healthy fats like nuts are high in calories, but pass through the body partially undigested, meaning less calories absorbed. Fats also help metabolism = more calories used.
Proteins are hard work to break down (thermic effect), so although we’re consuming calories, we’re burning more as well.
Natural healthy carbs are packed with fibre and fruit. That’s why they’re lower in calories. Glucose spikes and absorption are reduced by fibre.
Also calories in / out is a gross simplification of how the body works. Calories mean nothing if you’re causing glucose spikes and releasing insulin, both storing fat and being unable to access fat stores to burn.
