Carbs are not bad. The demonization of carbs on social media is a bunch of bullshit. Keto isn't magic. Basically it works for people who are "carb addicts" because they stop eating foods that they lose control over. They cut out the donuts and spaghetti and pizza and candy bars. Then they lose weight because suddenly they are in a caloric deficit! Amazing, right? It's the deficit that does the magic, not the fat.
The classic "get shreeded" diet is a ton of protein, lots of carbs, and minimal fat. Keto also is often deleterious to lipid values, so combining that WITH a cycle seems like a great recipe for some extra fucked up cholesterol levels.
