Quick answer: Non-starchy vegetables, avocado, chia seeds, flaxseed, some nuts and berries can provide meaningful fiber while keeping total carbohydrate relatively modest. Low carb can mean very different things, so context matters.
This guide answers the question high fiber low carb foods with a practical, evidence-aware approach. It is general wellness information, not a personal diagnosis.
Vegetables first
Broccoli, cauliflower, leafy greens, zucchini and other non-starchy vegetables provide fiber with fewer carbohydrates than grains or legumes.
In practice, the useful approach is to look at the pattern, reduce obvious aggravating factors, and make one change at a time. That makes it easier to tell what actually helps instead of changing several things at once.
Seeds and nuts
Chia and flax are particularly fiber-dense. Almonds, pistachios and other nuts contribute fiber too, along with fat and calories.

Fruit choices
Berries often provide more fiber for their carbohydrate content than many other fruits. Fruit does not need to be avoided just because carbohydrates are being moderated.

Avocado and concentrated fiber
Avocado is rich in fiber and fat with relatively little digestible carbohydrate. Psyllium is another concentrated source but should be used with adequate fluid.

Do not sacrifice overall nutrition
Very restrictive low-carb diets can reduce fiber and food variety. A broader balanced pattern is easier to sustain for many people.
