These are some of the most common questions I receive from readers who are tired of conflicting nutrition advice and want clear, science-based answers. Each response is grounded in physiology, clinical evidence, and real-world results. The goal is to cut through misinformation about low-carb, keto, and carnivore diets and provide practical guidance on metabolic health, hormones, fat loss, blood sugar, and long-term wellness. This FAQ offers accurate, transparent, and easy-to-understand information so you can make informed decisions without confusion or outdated myths. If you ever have a question you cannot find an evidence-based answer for, feel free to reach out. I am here to help clear up the misinformation and guide you toward what truly supports long-term health.
Do humans need carbohydrates to survive?
No. There is no biological requirement for dietary carbohydrates. The body can make all the glucose it needs through gluconeogenesis, a natural process that converts protein and fat into glucose. People thrive on low-carb and ketogenic diets because fat and ketones are efficient, stable fuels. While some people enjoy including small amounts of carbohydrates, they are not essential for human survival or optimal metabolic health.
Do seed oils support heart health?
Seed oils are often marketed as “heart healthy,” but they are highly processed, unstable fats that oxidize easily. Their high omega-6 content promotes inflammation when consumed in excess, especially alongside refined carbohydrates. Research consistently shows that lowering seed oils and choosing stable fats like butter, tallow, olive oil, and animal fats improves inflammation markers, satiety, and metabolic stability.
Is fiber essential for digestion?
Fiber is not essential. Many people digest food well without it, especially on low-carb or carnivore diets, where inflammation and bloating often improve or completely disappear. The belief that fiber is required for bowel function comes from population observational studies, not controlled clinical research. When the gut is inflamed or irritated, reducing fiber often calms symptoms, lowers bloating, and supports more predictable digestion.
Does meat cause cancer?
Fresh, unprocessed meat does not cause cancer. The claim comes from weak observational studies that cannot prove cause and effect. These studies often group processed foods, smoking, sugar intake, and other lifestyle factors into the category of “high meat consumption.” Controlled trials reveal no mechanism by which fresh meat harms human health. What consistently raises cancer risk is chronic inflammation, metabolic disease, smoking, alcohol, and ultraprocessed foods—not real meat.
Does eating fat make you gain fat?
No. Fat gain is driven primarily by chronically elevated insulin and excess carbohydrate intake, not by eating natural fats. Healthy fats from meat, eggs, seafood, and dairy keep blood sugar stable and improve satiety, which naturally reduces overeating. Many people lose weight more easily once they stop fearing fat and remove sugars and ultraprocessed carbohydrates from their diet.
Is diabetes inherited?
Diabetes is not a genetic destiny. While genetics can influence susceptibility, type 2 diabetes is a metabolic condition driven by chronic carbohydrate overload and rising insulin resistance. Families often share eating habits, not inherited diabetes. When people lower carbohydrates, reduce sugar, and stabilize insulin, blood glucose often improves significantly. Lifestyle—not genetics—is the dominant driver.
