What is the Keto Diet?

The ketogenic diet, commonly known as “keto,” is a low-carbohydrate, high-fat eating pattern designed to shift the body into a state called ketosis. In ketosis, the body burns fat for fuel instead of carbohydrates, producing molecules called ketones for energy.

Typical macronutrient breakdown:

• 70–75% of calories from healthy fats
• 20–25% of calories from protein
• 5–10% of calories from carbohydrates (usually less than 50g net carbs per day)

This unique balance encourages fat-burning, stabilizes blood sugar, and reduces hunger cravings — making it popular for both weight loss and medical management.

Benefits of a Keto Friendly Lifestyle

Research and real-world experience show a range of benefits from following a keto diet:

• Weight Loss: Reduced hunger, faster fat-burning, and long-term weight management.
• Metabolic Health: Improved insulin sensitivity and lower blood sugar, making it useful for type 2 diabetes management.
• Steady Energy: Fewer energy crashes since the body runs on fat instead of fluctuating blood sugar.
• Brain Health: Some evidence suggests benefits for memory, focus, and protection against neurological diseases.
• Reduced Inflammation: Lower carb intake often reduces markers of inflammation in the body.

However, keto isn’t for everyone. Consulting a healthcare provider is important before starting, especially for those with underlying medical conditions.

Challenges of Staying Keto Friendly

Despite its benefits, keto can be tricky to maintain long-term. Challenges include:

• Hidden Carbs: Sauces, dressings, and processed snacks often contain added sugar or starches.
• Keto Flu: Temporary symptoms like fatigue, headaches, and cravings as the body adapts to ketosis.
• Social Dining: Limited restaurant or travel options, especially in carb-heavy cuisines.
• Label Confusion: Not all “low carb” or “keto” marketing claims are accurate.
• Restrictive Nature: Missing out on fruits, grains, and certain comfort foods can make the diet feel limiting.

Food Scan Genius helps overcome these challenges by instantly flagging hidden carbs, calculating net carbs, and suggesting keto-friendly swaps.

Many “hidden carbs” come from sauces, condiments, or additives like maltodextrin — Food Scan Genius catches these instantly with barcode scanning.

The Global Popularity of Keto

Keto started as a medical diet for epilepsy in the 1920s, but has now become one of the most popular lifestyle diets worldwide. North America and Europe lead the adoption, while Asian countries are rapidly adapting with low-carb versions of traditional foods. The food industry has responded with a boom in keto-friendly snacks, protein bars, ready-to-drink shakes, and restaurant menu options.

This trend is more than a fad — it’s a long-term shift in consumer demand for low-carb, high-protein, and clean-label foods.
