Thank you for giving Biome Secret a try Kristine!
I hear you. Everyone's body is different and can take different amounts of time to kick into gear with all of the nutrition that Biome Secret shakes have to offer. Weight fluctuations are 100% normal, both up and down (this is especially true for women).
Weighing yourself: I can see that your order was upgraded to participate in the 15 day challenge - I believe in the challenge we suggest weighing yourself only on day 1 and on day 15, because everything in between is too short of a time period for meaningful changes to begin occurring. When weighing yourself, we recommend to always weigh yourself at the same time of the day, after using the bathroom but before eating or drinking anything. Most people choose to weigh themselves 1st thing in the morning in order to keep a consistent schedule with their weigh-in. Weighing yourself at different times of the day can really impact what you see on the scale.
Daily calorie reduction: It's important to be mindful of adjusting your lifestyle to target a meal-specific calorie reduction of 500 calories when drinking Biome Secret shakes. Most people choose to replace a high-calorie / low-nutritional-value meal in their day with a shake to get the maximum output from the additional nutrients and weight management properties. Both the welcome guide and the 15 day challenge emails try to offer some ideas on how to incorporate Biome Secret shakes into your day to help target this calorie reduction.
Muscle weighs more: Assuming the daily calorie reduction, one more consideration is that for most people, muscle weighs more than fat mass. Some people may already see improvements in their muscle to fat ratio after just 2 weeks, with more muscle mass. This is great news because at rest, muscle burns more calories than the equivalent fat mass. People with higher muscle mass have higher metabolic rates, which helps to create a positive feedback loop for your body to naturally continue burning more calories.
I hope this information helps - stick with it!

The taste is wonderful
The taste is wonderful! I do feel full and eat less. I do get a little upset tummy drinking them but not sure if it’s my own body cleansing and/or if I should try a different mixer. I have been a using coconut milk. I have not lost weight yet but am maintaining a not gaining. Am thinking about upping it to two packets a day for weight loss. Overall very pleased with this product.

Thank you for your feedback Rani! I hear you. Everyone's body is different and can take different amounts of time to kick into gear with all of the nutrition that Biome Secret shakes have to offer.
Some people may already see improvements in their muscle to fat ratio after just a few weeks, with more muscle mass (muscle weighs more than fat mass). This is great news because at rest, muscle burns more calories than the equivalent fat mass. People with higher muscle mass have higher metabolic rates, which helps to create a positive feedback loop for your body to naturally continue burning more calories.
Awesome to hear that you have tried it with coconut milk. Just in case you are substituting water with a different choice of liquid, just bear in mind that this adds additional calories to the shake. If you do this, you should make sure to reduce the calories you consume in some other part of your day. For example if you have added an additional 250 calories to the shake with fruit and a non-water substitute, you would want to remove those calories elsewhere in your daily diet.
Keep up the great work and stick to it!

Used to be delicious and helpful for weight loss
These shakes, especially the vanilla caramel, used to be amazing. I was losing weight and they also tasted good with a nice mouthfeel. But with the new formulation, whatever's been changed in the last several months, it is fairly terrible. I struggle to convince myself to drink it - the mouthfeel is very gross and viscous. When I reached out to customer service to express my opinion, the attitude was entirely blasé. I didn't feel taken seriously and I really miss drinking the old shakes every day.

Thank you for your feedback Anita, and thank you for trying our shakes!
We are continuously improving our recipe to maximize nutrition for all types of diets. As the formula is improved - some purposeful changes in flavor or consistency are created between batches. With the most recent batch you received, we increased our fiber content by 30% while reducing calories from 400 to 380.
Our shakes are made in small batches for freshness and nutrition - everyone has different tastes and I'm sorry our most recent shake improvements weren't to your liking! I have taken on your feedback about shake thickness and have passed it on for our next batch development - stay tuned! Thank you for your feedback!

Customer service could use some work
Update: (4) I finally was refunded for the masterpack that I threw away. I do understand that taste is subjective, but believe that satisfaction should be guaranteed for this type of product.
Update: (3) I received my second shipment, which was late & I had been 8 days without. Tried the vanilla-caramel flavor, which for me was disgusting & undrinkable. Then I found out that they changed the formula of the chocolate & we're no longer using stevia, instead they are using the artificial sweetener, sucralose, which for me has a bad aftertaste. THEY DO NOT HAVE A SATISFACTION GUARANTEE. If you don't like the shakes you're out the money unless you have a COMPLETELY UNOPENED MASTERPACK that you want to return to Germany & pay shipping. I'm very extremely disappointed as the first pack of chocolate I got I did like & was drafting a very positive review about, but now I really don't feel like I could recommend the shakes. I'm going to continue drinking the chocolate until I find a suitable replacement. It's hard to find a true "meal replacement" that is healthy, affordable & checks all the boxes. In the meantime I'm going to try a trick that I read online. I ordered some organic cocoa & I'm going to add a teaspoon to my chocolate shake & see if that helps reduce the aftertaste from a sucralose. I gave them 2 stars instead of 1 only due to the fact that they seemed to be trying to work with me & have sent a free package due to my shipping issues. If I find out I can't tolerate the aftertaste or find a better replacement I will be canceling.
_____________________________
Update to 3 stars: (2) I was contacted & they are working with me to correct the shipping issue & doing everything they can to make sure I don't miss anymore days. Unfortunately, I'm going to have to pay every 3 weeks just to make sure I get them on time. I do appreciate that they are actively communicating with me & working on resolving the problem. I do want to continue with the shakes because I believe that they are a truly good meal replacement & will help me be healthier & lose weight. I have already lost 10lbs this year. I have a shake for breakfast & then 2 other meals around 400 calorie. Also, as needed I eat fresh fruit or a boiled egg as a snack. Very happy to be starting 2025 with positive changes. The shake definitely helps & is very affordable.
____________________________
(1) This review is only about customer service. First off they don't seem to know their product. I asked a question about not drinking it all at once & putting it in the refrigerator to finish later. I was given some answer about it separating & not tasting good so I should drink it all at once or just mix it half at a time. The proper answer I found from Google is that it contains digestive enzymes so should be consumed within 20 to 30 minutes of mixing with water since you're activating the digestive enzymes, which makes sense. Second issue, which is most frustrating, is shipping. They default you when you first sign up for every 2 weeks so I figured since I was trying it out to see if I liked it first that I would do that instead of getting 2 packages every 4 weeks. Shortly after I got it I realized that I wanted to go ahead & get it every 2 weeks so that I would save shipping charges because I decided I was going to commit to drinking it everyday for the year at least. I contacted them and they said that they would switch it because you don't seem to have a lot of control of things like that through the website. When it was getting close to when I was supposed to be receiving the second order I looked it up & saw that I wasn't supposed to get it until the end of the month, which would have been weeks after I ran out. I contacted somebody and they said that they fixed it, but the best they could do was have it delivered on the 18th of January, which would have only had me miss 2 days of shakes. Unfortunately, they were wrong in their statement to me. The second shipment was just shipped today on the 20th, so I've already missed 5 days of shakes. I'm probably going to miss at least another 2 or 3. I do see that she updated me to every 4 weeks, but it looks like they're going to be charging me & then shipping out at the 4 week mark, which means I possibly, most likely, am going to be missing days. I canceled my subscriptions for supplements because I started drinking the shake everyday, but now I'm not having my supplements, or the shakes, so my 2025 goal of being more healthy is jeopardized because of horrible customer service from this company. I'm incredibly frustrated because I did a lot of research & these are the shakes that I would like to be drinking everyday, but at this rate it looks like I'm going to be canceling & moving to another brand, which will be disappointing, but I believe that customer service is extremely important and they are seriously lacking in that area.
