10 Weeks - Mixed Feelings

Unfortunately I have not seen the results from this device after 2 1 2 weeks of us I have followed all the instructions to the letter and had to contact customer support for advice After a long conversation and troubleshooting with my device it was decided that I need a new device which they are sending me I will say it is tricky at first but I can see the potential but just not of yet Also customer support was awesome Very Very helpful So now I am looking forward to trying it again with a new device when I get it Kat

Needs Synch with Android MFP

I ve been using Lumen 10 weeks now I have to say I have not achieved the promised results despite following the program religiously I achieve fat burn level 1 2 every day but my smart scale says I am gaining body fat Readings are all over the place high before food low after I can be level 5 at 11am and level 1 2 hours later then back to 5 There is no reason to the levels sometimes low pre exercise then high sometimes the reverse The app is however good and well laid out and I have to say the support team are excellent and responsive The sign up promises are a bit of a fantasy so don t be fooled Essentially this is a low carb diet plan In 10 weeks I have only had 1 high carb boost day You can buy the Atkins diet book and achieve the same result without the fancy graphics Jury is definitely out on the science as this is too random

It s great to learn about how your

Data seems to align with my health initiatives Great training videos My major issue is it does not synch with Android Myfitness Pal which I use for a health insurance program

It has potential for self starters who have time to really address the feedback that it gives

It s great to learn about how your eating and exercise affect your metabolism The constant breath testing is really annoying at times and not easy to master I think they are looking at multiple tags to one breath that would help

Valuable tool but not enough value for money

This app and product have the potential for great feedback It takes a very independent person who knows what to ask and how to navigate the feedback from the app and nutritionists I like seeing how my body responds to different foods activities etc and using that feedback to make healthier changes However I feel like I m missing out on unlocking the full potential due to my less than predictable routine as a stay at home mom of 3 under 3 The ability to sit down and take a breath in specific time frame windows is not always as easy as it sounds I was also disappointed by paying so much more for VIP services that are not very clear on how to use They have a good system but it needs some fine tuning in the food log and how to use

While lumen forces me to think about

Four stars as this app gave me an insight into how my metabolism works and I am in much better shape because of it Two stars for the very high membership fee Lumen should offer the option of a limited membership to return customers to allow the continued use of the device without the extras like the daily nutritional advice videos etc I did not renew my membership as the device was the most valuable tool for me and I couldn t justify the continued cost

Jury still out

While lumen forces me to think about what I should it I am not seeing any weight loss My weight fluctuates using lumen The food log does not allow me to go back and log for a day after - it is difficult to log food on the same day I still did not get my answer from the support team regarding weight fluctuations Overall it is a tool that helps you beingmindful and gives you measurements but they still do not make sense to me I have been using lumen since March

K

I was hoping for more insight into when

The monthly subscription is much to expensive and as much as the device cost all other should have been a given for at least 2-3yrs
N

Canceled due to changes

Frequently Asked Questions

Lumen is a personalized metabolic health platform. It consists of a handheld breath analysis device and a mobile application designed to measure your metabolism in real-time. By analyzing the carbon dioxide (CO2) concentration in your breath, Lumen determines whether your body is primarily burning carbohydrates or fats for energy. This data provides personalized insights and actionable guidance for nutrition, fitness, and overall wellness, helping you optimize your metabolic health.

The Lumen device is a portable breathalyzer. Users breathe into the device, typically each morning and at key moments throughout the day. It measures the concentration of CO2 in a single exhalation. This measurement indicates your body's current primary fuel source—carbohydrates or fats. This state is known as metabolic flexibility. The result is instantly synced to the Lumen mobile app, which interprets the data to provide a personalized metabolic snapshot and daily recommendations.

The Lumen app serves as the central hub for the user experience. Key features include a Daily Metabolism Score indicating your metabolic flexibility; Customized Nutrition Plans with meal and macronutrient guidance tailored to your goals; Fitness Optimization insights for pre- and post-workout nutrition; Sleep and Metabolism Tracking to analyze the impact of rest on your metabolic rate; and access to Educational Content with science-backed information on metabolism, nutrition, and habit formation.

Lumen is designed for health-conscious individuals, athletes, and anyone seeking a deeper, data-driven understanding of their body's metabolism. It is particularly relevant for those interested in personalized nutrition, biohacking, metabolic flexibility, and moving beyond generic diet plans. Users typically aim for goals such as weight management, improved energy levels, enhanced athletic performance, and overall metabolic health optimization.

Metabolic flexibility refers to the body's ability to efficiently switch between burning carbohydrates and fats for fuel based on availability and demand. Lumen measures this state to provide your daily metabolism score. Achieving metabolic flexibility is associated with benefits such as more stable energy levels, efficient fat burning, improved insulin sensitivity, and better overall metabolic health. The Lumen platform provides personalized guidance to help users develop and maintain this flexibility.
