What is the 5 Bite Diet?

Dread counting calories? Hate tracking your macros? The 5 Bite diet might be perfect for you.

How does it work?

The 5 Bite diet is built on the premise that you can eat whatever you want - but you’re limited to just 5 bites of it. The 5 Bite diet was created by Dr. Alwin Lewis and first published in his book, “Why Weight Around?” in 2007. It’s meant to simulate the eating patterns of someone who has had gastric bypass surgery - and we all know how well that works for weight loss.

Dr. Lewis recommends skipping breakfast (a type of intermittent fasting - check out our intermittent fasting article) and having just 5 bites of any meal for lunch and dinner. You are allowed 0 calorie beverages throughout the day and Dr. Lewis recommends taking a multivitamin along with this diet. You must be sure to include protein in your daily bites. You are also allowed 2 separate one-bite snacks a day. 

What are the benefits?

The benefits are fairly straight forward. You will:

  • Learn to exercise portion control
  • Lose weight
  • Not have to count macros or calories
  • Not have to eliminate specific foods from your diet

What are the cons of the 5 Bite diet?

The 5 Bite diet is commonly seen as a fad diet, that, while it will lead to quick weight loss, is not entirely sustainable long-term. The total calorie intake while on this diet will be extremely low, and therefore your nutrients will be as well.

Should I try it?

That’s entirely up to you. Everyone is unique and different diets work for different people in different ways. I will say - I have never used the 5 Bite diet as a long term weight loss strategy but I did use it once to get me through the holidays. I have a hard time with holiday weight gain (doesn’t everyone??) and in order to avoid that one year, I implemented the 5 bite diet on days that I knew I’d be most likely to overeat. I did not gain any excess weight that year so it definitely worked!

Did you try the 5 Bite diet? Or have you tried it before? What did you think? I’d love to hear about it.
