Unlock the Health Benefits of Collagen and Intermittent Fasting: Is it a Good Match?

Collagen and Intermittent Fasting: Is it a Good Match?

Collagen and intermittent fasting – two buzzwords that have been taking the health and wellness world by storm. But do they really go hand-in-hand? If you define fasting by the traditional sense, meaning abstinence from food and/or drink for a certain amount of time, then yes, collagen technically breaks the fast. But, luckily, collagen fits even better into a keto diet than it does intermittent fasting.

What Is Keto?

Ketosis is a process maintained by eliminating carbs from the diet, which forces your body to switch from burning glucose for energy to burning fat for energy. When the body is in ketosis, it breaks down fatty acids into molecules called ketones, which become the body’s main source of energy. Studies have shown that following a keto diet can help you lose weight and reduce your risk of diabetes and heart disease.

The great thing about a ketogenic diet is that it allows you to still enjoy certain foods, like collagen, that would normally break a fast. Collagen will help you feel full and sustain you for the rest of the day. Since collagen is keto, you can still get to ketosis during the fast, and the added protein can help you stay in ketosis longer.

Can You Have Collagen During Intermittent Fasting?

Technically yes, but not all collagen supplements will do the trick. Collagen brands such as Vital Proteins have collagen peptides, which are hydrolyzed for easy digestion and absorption by the body. This makes collagen peptides a great supplement for intermittent fasting since it will not break your fast.

Another great option is collagen in your coffee. Collagen in your coffee is probably fine for fat-burning and may even suppress appetite and prolong and enhance your fast – in moderate amounts. But, this depends upon the number of calories you allow yourself during the fasting window.

Benefits of Collagen During Intermittent Fasting

Collagen intake during intermittent fast is a great way to ensure you are getting the right nutrition and staying full. It’s a great pairing if you are intermittent fasting and can help to regulate and induce autophagy. With that said, there are many different types of intermittent fasting, so you should speak to a doctor before beginning any fasting protocol.

There may arguably be some therapeutic perks to taking collagen in a fasted state, however I typically recommend keeping it during the eating period. This is because collagen is a great source of energy that can help you feel full and sustain you for the rest of the day.

Autophagy and Collagen

Like collagen supplementation, intermittent fasting has been linked to increased autophagy. Autophagy is the process by which cells are recycled and regenerated, and it has been linked to many health benefits, including improved weight loss and better blood sugar control.

Intermittent fasting and collagen supplementation can help support autophagy and help you reach your health and wellness goals.


Collagen and intermittent fasting can be a great duo for supporting your health and wellness goals. Collagen peptides are a great supplement to add to your diet while fasting since it will not break the fast and can help you feel full and sustain you for the rest of the day. But, be sure to consult a doctor before beginning any fasting protocol, and make sure to stick to your calorie allotment during the fasting window.

Is it possible to consume collagen while participating in intermittent fasting?

Any item that contains any amount of calories will interrupt a fast, and this includes collagen.

At what point during my intermittent fasting should I consume collagen?

Taking collagen in the morning before your fast and at the break of fast can help to keep you feeling full and energized throughout the day. Since collagen is keto-friendly, you can still stay in ketosis while fasting, and you won’t have to worry about feeling bloated.

Does abstaining from food have an impact on collagen?

Fasting led to a similar reduction in the rate of collagen production by the parietal bone compared to cartilage, with each experiencing a 24% and 26% decline in relative production of the control, respectively. The parietal bone primarily makes type I collagen, and cartilage largely produces type I1 collagen.

Does collagen interfere with autophagy?

Collagen supplements are a highly effective, pure, and dependable source of protein that can actually encourage the formation of additional collagen protein in the future! This is a great combination if you are practicing intermittent fasting and can assist with controlling and stimulating autophagy.
