How does the keto diet actually work?

The high-fat, low-carb keto diet gives you energy, keeps your blood sugar stable, and leads to rapid weight loss. The keto diet forces your body to burn fat, rather than glucose, for energy. This puts you into ketosis, aka prime weight loss mode. Ketones help control hormones that influence appetite.

In order to get the most out of a ketogenic diet, you must eat high-fat foods and limit your carb intake to fewer than 30–50 grams per day.

If you stick with it, the benefits of a ketogenic diet are extremely impressive — especially for health and weight loss.

Ketogenic diets can also reduce metabolic disease risk factors and even fight diseases like type 2 diabetes and obesity.

Very Low-Carb Foods

Some foods, like high fat dairy, meat, fish, cheese have almost no carbs. To eat 20 grams of net carbs is almost impossible if you stick to them. No wonder you can eat your fill of these foods and still lose weight. Here’s how much you’d need to eat to hit the daily limit:

Meat – an almost infinite amount (meat is virtually free of carbs)
Fish – an almost infinite amount
Olive oil – an infinite amount
Coconut fat – an infinite amount
Butter – 44 pounds (20 kilos)
Eggs – 30 eggs (one egg contains less than 1 gram of carbs)
Avocado – 7 avocados (net carbs per avocado: 3)
Cheese – 3 pounds (1.5 kilo)
Béarnaise sauce – 2 pounds (1 kilo)
