If you’re following intermittent fasting, animal-based proteins can be a great choice to support your dietary goals. Animal-based proteins, such as lean meats, poultry, fish, and dairy products, are rich in essential amino acids that your body needs for muscle repair and growth. These proteins are also highly bioavailable, meaning that your body can easily absorb and utilize them.

Including animal-based proteins in your meals during your eating window can help you feel fuller for longer, prevent muscle loss, and support your weight loss or muscle building goals.

Additionally, animal-based proteins are a great source of vitamins and minerals, including iron, zinc, and B vitamins, which are important for overall health and energy production.

Remember to choose lean cuts of meat, opt for skinless poultry, and select low-fat dairy products to keep your calorie intake in check while still getting the protein you need.

Protein Supplements

Whey Protein

To optimize your intermittent fasting results, consider incorporating whey protein into your eating window.

Whey protein is a highly beneficial supplement that can help you meet your protein needs during the limited eating period of intermittent fasting.

Whey protein is derived from milk and is known for its high bioavailability, meaning that your body can easily absorb and utilize it. This makes it an excellent choice for muscle recovery and growth.

Additionally, whey protein is rich in essential amino acids, including leucine, which plays a crucial role in muscle protein synthesis.

Egg Protein

Wondering how to break your fast? Eggs, fruit, or oatmeal are good choices.

For optimal results in your intermittent fasting journey, incorporate egg protein into your eating window.

Egg protein is an excellent choice for those following intermittent fasting due to its high protein content and essential amino acids.

Eggs are also a great source of vitamins and minerals, including vitamin B12, vitamin D, and selenium. Whether you prefer them boiled, scrambled, or in an omelette, eggs are a versatile and convenient protein option.

Just be sure to consume them within your designated eating window to maximize their benefits and support your intermittent fasting goals.
