FeastByFist is a food diary powered by patent-pending AR (Augmented Reality) portion control technology in your pocket!

But what’s different about FeastByFist?

FeastByFist helps you in whatever diet you choose, whether that’s the Whole 30, Keto, South Beach, etc. FeastByFist reduces the complexity in your meal planning by overlaying an AR portion circle onto the food so you can decide the appropriate amount to eat.

By eliminating the likelihood of overconsumption, FeastByFist enables you to be more mindful of your meal. Sharing your progress not only increases your own happiness but will spread cheer to your friends and family.

That’s great, but why should I worry about portion control?

We’re as environmentally minded as you are. As technology further strengthens the interconnectivity of the world, we understand that an individual can have a global impact. We want to reduce consumption while remaining mindful of our own lives. FeastByFist can help you achieve the goal.

Simple and effective

I started using FeastByFist to tackle my stubborn baby weight. I’m a firm believer in “all food is good food” and don’t want to deprive myself of occasional sweets either. FeastByFist is based on portion control and food journaling. The concept of putting an Augmented Reality portion circle on my plate is ingenious and saves me tons of time and energy measuring my meals. It automatically logged my meals and portion size in my personal journals. I don’t need to do anything other than pressing a button and eating my food. I also noticed being more mindful of what I’m eating. Taking a picture of my food slows me down from grabbing and eating everything in my pantry. I even started plating my meals and incorporate nice colors from fruits and veggies so I feel good about sharing my meal photos. There are lots of good healthy habits from using FeastByFist. I’ve lost 15 lbs so far and can’t wait to get to my dream goal soon!

The merge of creativity, simplicity and optimal utility

I am amazed by the creativity of utilizing Augmented Reality technology in helping me with my diet. With simple actions of selecting my meal type and portion size, I can be mindful of what I am eating as well as how much I am eating. Then by snapping a picture of my food, I get an instant analytical report that are easy to understand and follow. Those beautiful pictures of my photo food journal also contain portion size so my dietician can get a perspective of my portion size. Comparing my portion size from yesterday and a week ago also help me to stay on track. What a useful App full of creativity while simple to use!
