Low-carb, keto, low-fat, calorie-deficit, and intermittent fasting diets help manage weight by controlling carbs, fats, and eating times.

High-protein or muscle-building diets like Paleo, Zone, and Carnivore focus on protein-rich foods such as meat, eggs, and fish, reducing grains and processed items to enhance muscle growth, strength, and overall performance.

Health conditions that require diet planning include obesity, diabetes, heart disease, thyroid disorders, kidney and liver problems, rheumatoid arthritis, hypertension, PCOS, digestive issues, and nutrient deficiencies.
