What to Eat in a Keto Diet: The Ultimate Guide for Beginners


The keto diet has become increasingly popular for its potential to promote weight loss and improve health markers such as blood sugar and cholesterol levels. The diet involves cutting out most carbs and replacing them with fats, in order to put the body into a state of ketosis. If you’re interested in starting a keto diet but unsure of what types of food to eat, this guide is for you. We’ll cover everything you need to know, from the science behind the diet to easy meal prep tips and delicious recipes to try.

The Science Behind the Keto Diet: Understanding How it Works and What to Eat

To understand how the keto diet works, it’s important to first understand ketosis. When the body doesn’t have enough glucose (from carbs) to use for energy, it starts breaking down fat instead. This produces ketones, which can fuel the body and also act as an appetite suppressant. In order to achieve ketosis, the keto diet involves eating a high fat, moderate protein, and low-carb diet. Specifically, macronutrient ratios for the keto diet are 75% fat, 20% protein, and 5% carbs.

Foods that are allowed on the keto diet include:

  • Meat (beef, pork, poultry, lamb)
  • Fish and seafood
  • Eggs
  • Healthy fats (avocado, olive oil, coconut oil)
  • Nuts and seeds (almonds, chia seeds, flaxseeds, coconut)
  • Dairy (cheese, butter, cream)
  • Low-carb vegetables (leafy greens, cauliflower, broccoli, bell peppers)

A Beginner’s Guide to Keto Diet: Best Foods to Eat and Avoid

If you’re new to the keto diet, it can be overwhelming to know which foods are best to eat and which to avoid. The key is to focus on foods that are high in healthy fats and low in carbs. Good sources of protein include meat, fish, and eggs. Healthy fats can be found in foods like nuts, seeds, avocado, and olive oil. Low-carb vegetables like leafy greens, cauliflower, and broccoli can also be included in your diet. On the other hand, it’s important to avoid or reduce high-carb foods such as bread, rice, pasta, and sugar.
