The best snacks on a keto diet:
Eggs: They are nutrient dense, filling and easy to pack and bring anywhere you go. Boil a bunch at once and store in the fridge for easy access. Enjoy with salt or a dollop of mayonnaise.
Full-fat cheeses: Hard cheeses like Cheddar, Gouda, Gruyère and soft cheeses like Brie or goat cheese contain a good amount of both protein and high-quality fat that will keep your hunger at bay for a long time.
Avocados: A keto staple, packed with healthy fats and potassium.
Low-carb nuts and seeds: A handful of Brazil nuts, macadamia or pecans often do the trick. You also get a dose of important vitamins and minerals such as magnesium and potassium. Just make sure you don’t overeat, because nuts will probably kick you out of ketosis and slow down your weight loss. Allergic to nuts? Try pumpkin seeds!
Other tasty snacks: Pickled cucumbers (make sure the pickle juice is sugar-free), cold cuts, bacon, smoked mackerel, olives and vegetables.
The “keto” in a ketogenic diet comes from the fact that it allows the body to produce small fuel molecules called “ketones”. This is an alternative fuel source for the body, used when blood sugar (glucose) is in short supply.
The liver produces ketones from fat. These ketones then serve as a fuel source throughout the body, especially for the brain.
The brain is a hungry organ that consumes lots of energy every day, and it can’t run on fat directly. It can only run on glucose… or ketones.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7.
When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off.
This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy.
This may help keep you alert and focused.
When the body produces ketones, it enters a metabolic state called ketosis. The fastest way to get there is by fasting – not eating anything – but nobody can fast forever.
A keto diet, on the other hand, can be eaten indefinitely and also results in ketosis. It has many of the benefits of fasting – including weight loss – without having to fast.
