FENFAST 375 Reviews from Customers

FENFAST 375 Customer ReviewsElaine (Bristol, CT) – I bought FENFAST because I wanted to get better results out of my diet. I took Adipex last year and lost 23 pounds, but gained it back over the past 6 months. I read that these pills are a good substitute for Adipex so I bought some. I’m now kicking myself in the butt since I didn’t just go ahead and buy the 3 bottles at once that I should have got to save the money, and I paid full price for one. I won’t make that mistake again and I’ll buy 3 at a time because it really works well. I wouldn’t say it feels the same as Adipex, but that isn’t a bad thing.
FENFAST 375 Customer ReviewsDora (Albuquerque, NM) – I’ve been taking these pills [FENFAST 375] two times per day for 4 days now and here’s what I’ve got out of it so far:
1 – It does seem to do what it says it will do. I crave snacks way less and I get full a lot faster than I normally do.
2 – it is a lot easier to change my eating habits. I don’t have seconds anymore because I just don’t feel that I want them.
3 – I have a lot more energy, especially for the first 2 thirds of the day, so that’s the best time to exercise.
4 – I’m losing weight! 3 pounds gone already. That’s almost a pound every day.
FENFAST 375 Customer ReviewsAshley R. (San Jose, CA) –
I bought fenfast and it arrived 2 weeks ago and I’ve been following the exact instructions for it. I take 2 pills every day, one in the moring 30 minutes before breakfast, and one around noon, 30 mintues before lunch. I lost 5 pounds in my first week and 3 lbs in my second week.
FENFAST 375 Customer ReviewsJohn F. (Brooklyn, NY) – 15 days in and I’ve already lost 10 and a half pounds! I’ll be at my goal weight before the summer even starts.
FENFAST 375 Customer ReviewsTerry M. (Corning, NY) – These aren’t “magic pills” but they’re “reality pills” if you want to call them that. Fenfast 375 hasn’t given me any miracles but along with my own diet, I’ve been able to lose 14 pounds in 19 days. That’s by far the most amount of weight I’ve ever lost in that time, even when I have stuck to a diet without cheating. I haven’t even been dieting strictly, I’ve just cut out all the crap like soda and chips.

FENFAST 375 Customer ReviewsEmily R. (Ontario, Canada) – When I first started with FENFAST, I weighed 212 pounds. I have been taking it for 7 full days exactly like the package directions say, and I just weighed myself and I’m 208 now. I have been doing a daily walk and I did pilates one day. I like that this pill makes it easier to stick to the diet, because I’m really not as hungry as I usually am. I still eat a good meal, but I never need seconds anymore, and I don’t find that I get hungry after an hour or so, so I don’t snack anymore. It’s made a real difference.
FENFAST 375 Customer ReviewsTarra (Dallas, TX) – FENFAST, exercise, sleep, and a healthy diet has changed my life. I don’t want to sound like an infomercial, but if you’d lost almost 25 pounds in 6 weeks, you would be saying the same kind of thing.
FENFAST 375 Customer ReviewsMike J. (Philadelphia, PA) – Pills [FENFAST 375] work great for hunger and energy, but there is still some of it that is up to you to do. I have cut out alcohol, stopped being lazy, and I don’t go to fast food places anymore. These pills let me eat right without feeling starving.
FENFAST 375 Customer ReviewsMarylou N. (Lyndon, KY) – FENFAST is the best thing I have ever tried to loose weight. I loose at least 3 pounds every week and I don’t have to try too hard because this makes it so easy.

Why Are FENFAST 375® Diet Pills So Helpful?

The reason that FENFAST 375 reviews are so positive, and it is quickly becoming one of the most popular diet pills boils right down to the FENFAST proprietary formula. It is made up of only the best quality ingredients, including: L-Phenylalanine, Caffeine, L-Theanine and Theobromine. Every one of those ingredients has been scientifically researched to understand its effects and safety, before the development team at Intechra Health Inc. brought them together to create a product dieters love.

Once these ingredients are packed into this American-manufactured tablet, the outcome is a premium quality high energy formulation. Dieters can use this energizing effect as a part of a weight loss strategy to burn far more calories and fats than they might achieve unassisted. That said, the top benefit occurs when this diet pill is taken alongside an eating and exercise program that has been recommended by a doctor, based on the dieter’s individual nutrition needs and fitness level. This type of weight management strategy helps to skyrocket the body’s natural capabilities for blasting through consumed calories and stored fats. It is in this way that the best results can be achieved with an alternative to Adipex.

In fact, despite the fact that FENFAST 375 is not at all the same as that prescription drug, many dieters choose to use it alongside a similar weight loss strategy. This is because FENFAST 375’s non-prescription tablet was created to provide support without subjecting users to the risk of dependency, severe withdrawal symptoms or more problematic side effects linked with prescription drug use. This is why many FENFAST 375 reviews say it can be used in the same way as an Adipex alternative.

How FENFAST 375® Works

FENFAST 375 tablets work in a number of different ways to help reduce the challenges associated with dieting. It does this through premium, clinically researched non-prescription ingredients. These top quality, carefully balanced ingredients are combined into an easy to swallow tablet. The outcome is a product offering a powerful alternative to prescription diet pills like Phentermine 37.5 mg (Adipex).

It took meticulous investigation for the development team at Intechra Health to be able to come up with the proprietary formula that would be able to assist dieters on a number of levels in a safe and effective way. They needed to make certain that they would be able to not only generate the types of positive effects that the prescription drugs could provide, but that FENFAST 375 would also avoid the disadvantages of those medications, such as dependency and strong side effects risks.

The key to the achievement while using these pills which are manufactured in a US facility, check out FENFAST 375 reviews for the proprietary formula. It includes:

  • L-Phenylalanine
  • Caffeine
  • L-Theanine
  • Theobromine

Those four ingredients have all been clinically studied. That research was taken into careful account by the experts of weight loss at Intechra Health Inc. It is this formula that so many customers have raved about as an alternative to Adipex and Phentermine like no other.

Intechra Health chose L-Phenylalanine as the top ingredient because it has been scientifically studied for its effects that support weight loss efforts on many levels. When compared to a placebo, this ingredient has been shown in research to release cholecystokinin (CCK), which may reduce food intake in humans. It is in this way that the ingredient has been shown to function within the body. Reduced food intake, combined with healthy, reduced calorie choices can help to support a more effective weight loss strategy.

Next, they selected caffeine, which is an extremely widely known stimulant that has been extensively studied for a series of different effects that it can produce. Primarily, it has been shown in research to suppress leptin, increase thermogenesis and increase energy levels. This made it an ideal complement for L-Phenylalanine, as it gave the FENFAST® 375 formula the ability to provide even more to its users.

Finally, Theobromine and L-Theanine were both chosen because of the research suggesting that they are beneficial when it comes to supporting a dieter’s efforts to lose weight through diet and exercise. Dieters who are energized can better keep to their strategy for success. The Intechra Health team recognized this in their development of FENFAST 375 as it is vital to maintaining the necessary energy for keeping up a weight management strategy. 

What You Can Expect When You Take FENFAST 375

As you do your research into FENFAST 375 reviews, and you read all of the positive FENFAST reviews, you will begin to realize that this diet pill can really work for a lot of people. But, if you decide that you want to give it a try, you might also want to know what to expect, right? Well, here is the basic breakdown of what you might feel when you are taking FENFAST 375 as directed.

You may feel more energized. The ingredients in FENFAST 375 can help you get a nice boost of physical energy. Use that energy to lead a more active lifestyle that will have you naturally burning through more calories and fat than you would if you were leading a sedentary lifestyle. For those who struggle with maintaining a workout routine with consistency, FENFAST 375 can be really beneficial. With the energy that you can get from these pills, you can power through a tough workout, get your sweat on, get your heart rate up, and burn through calories like a pro.

In addition to feeling more energized, what you might notice as well when you start taking FENFAST 375 is that you will feel more focused. What’s the big deal about being focused while you are trying to lose weight? Well, have you ever found that your willpower was so low because you were dieting and low on energy and focus? Then you know how this can take its toll on your efforts. With more focus, you will be able to stick to your diet plan and your exercise routine with greater ease.

Don’t Just Buy Adipex Without First Exploring Your Options

You may be tempted to buy Adipex if you are seeking a potent diet pill that well help you slim down fast. However, it is important to know that there are other weight management aids available and not everyone is an ideal candidate for prescription diet medications.

In fact, many people who think that they can take these drugs, find out that they can’t due to reasons that may include:

  • Not the right BMI
  • Medical issues
  • Taking certain medications

For these individuals, the risk of taking prescription diet pills like Phentermine or Adipex would outweigh the potential benefits.

Over the counter weight management aids like FENFAST 375 may be a better and safer option for overweight individuals who need support with their dieting and exercising efforts to reach their goals.

37 Thoughts to “FENFAST 375”

  1. Cindy

    Fenfast is staggeringly good. I’ve experienced a loss of 3 pounds in one week and I hope to do the same over the weeks to come. I can’t tell you what a difference this has made in my life. I already feel much healthier and better.

  2. Patricia

    I can really get the most out of my diet with Fenfast. I eat less but exercise more. That’s the best way to make sure the weight goes away.

  3. Maria

    I am depending on Fenfast to keep me motivated for a lot of weight loss. So far so good. I have lsot 16 pounds so I’m just over half way. It’s not without its challenges but it is very fast

  4. Weight Loss Freak

    Why can’t everything be like Fenfast? It’s such a relief to come across a product that will actually give what it promises and be affordable and safe at the same time. That’s really not something that I see every day. I have become quite a doubtful shopper but it gives me just a little bit of faith in companies again when I see that there are some good ones out there.

  5. Paul Novak

    I had my doubts that FenFast would provide strong results that would be effective enough to actually help with dieting, when I saw that it only had three ingredients. That didn’t look like it was enough. But I’ve lost 19 pounds in a month and one week so I was wrong.

  6. Troy B

    These pills really didn’t give me the energy level that I was expecting. I had to move my workout at the gym to my lunch hour instead of at the end of the day. I lose about 2 to 3 pounds every week, though, so FenFast is definitely working for me.

    1. Lily

      I’m surprised. Fenfast made me just explode with energy. I’m usually dragging at the best of times and with this I just keep on going and don’t even think about being tired, because I’m not! I lose about the same amoutn of weight as you ever week – 2 or 3 pounds – and I haven’t plateaued even thought it’s been nearly 3 months.

      I guess it works a bit different for everyone, but it still gets the job done!

  7. Zayden

    Fenfast is by far the best diet pill I’ve ever tried. I only need to lose 9 more pounds and I’ll have reached my goal. It’ll be gone before the end of the month!

  8. Heather

    When I diet, I refuse to stop eating the meals that I love, so I have to base my program on exercise and a good diet pill. That’s what I found in fenfast. I can hit the elliptical every day, eat everything I want, and take 2 tablets per day and that’s all I need to get there. I’ve only had that success with prescription pills in the past. This time I can do it without the side effects and extra cost. This is great.

  9. Austin

    Dieting can be so hard because your body is pretty much miserable all the time. Fenfast doesn’t make you lose the weight by itself. It’s even better than that in my opinion. It makes it so that you still have to diet but that it doesn’t suck while you do.

  10. Fred C

    I can’t believe how quickly these things kick in. I took my first FenFast at 6am this morning when I first got up. Before I was done brushing my teeth and showering, I could already feel the energy boost that they give. When I sat down for my breakfast – this is about a half hour after taking it – I was finding that I got full a lot faster so I didn’t have to eat near as much as usual.

  11. Carla

    Thank goodness for FenFast. I have to lose weight or my health is going to be in a lot of trouble and I have had nothing but problems with Phentermine. That was a waste of money, but my sister was taking Fenfast with a lot of luck so I figured what the heck. I have already lost 5 pounds and it’s only been 8 days!

  12. DietWhisperer22

    Fenfast takes any diet and turns it into something that works. As long as you’re actually doing some exercise and you’re eating good healthy food, then you’re a shoe in for weight loss. That’s what I’ve found since I’m eating the same foods, only less – since I’m just not hungry beaause of the pill’s appetite shrinking effect – and I get out for a good walk every single day. That’s all it takes to make sure I’m losing way more weight than I have in previous diets. On average, I lose 2 pounds per week, but I lost 3 pounds last week, so it can definitely help with more. I imagine that people who are using the gym and changing their diet more are losing even more than that, but I’m taking the easy road.

  13. Rodney

    Fenfast gets my day off to a bang of a start because when I take it first thing in the morning, I’m suddenly zapped with a whole pile of energy. Then, before I know it, I’m zippng through the day. The fun part is that even though I’m very productive and I get a lot done, I don’t find myself getting hungry. It’s perfect!

  14. Daphne E

    I’m really interested in taking Fenfast but I’m not too sure if it would be right for me because I have trouble sleeping on a good day, and I’m a little nervous that the energy boost this pill is supposed to give will make sleeping even more difficult. Has anyone had trouble sleeping taking Fenfast?

  15. Josh

    This is good stuff. One month in, 16 pounds lighter.

  16. Justin

    I like a good diet pill that actually shows what the ingredients are. I trusted fenfast right away when I got to see that it actually shows what’s in it. It’s not right that other ones don’t do that. Does anyone know if companies have to reveal what’s in them in the United States? If they don’t, they should. I would never take anything that doesn’t post its ingredients.

  17. Jayden on Fenfast

    I took a bottle of Fenfast for a month and I really didn’t think it was cutting back on my appetite enough that I would take it for another month, so I went off it. Let me tell you, it’s when you stop using it that you realize what a difference it was making. I can’t believe the hunger I was feeling by trying to eat the same amount of food as I had when I was taking the pills. I just wanted to share that so that if anyone else is taking it and thinks it’s not too strong, wait till you go off it and you’ll really discover the difference it makes.

  18. Cate Curiosity

    I want to start losing weight but I’m still breast feeding. I really think FenFast would be good for me, but I don’t know if it’s safe to take right now. I am going to talk to my doctor of course, but I’d like to know what other people think.

    1. Moderator

      Cate – The manufacturer does not recommend taking FenFast when breastfeeding. I would recommend that you wait until you are done breastfeeding before taking this product.

  19. Taylor

    I’m wondering if anybody can tell me how to lose weight faster with Fenfast than I am. I keep reading about people losing 20 pounds in a month and all that but I only lost 12 after the first bottle. What am I doing wrong?

    1. Gabriel

      Taylor: I’m not losing 20 pounds per month on FenFast. I’ve been losing about 12 per month. I’m in my second bottle (month) now and I lost 12 pounds the first month, and the three weeks that followed I’ve lost another 10 pounds. So I’ll probably lose about 12-14ish in the second month. I think it all depends on how big you are, what you eat, and how much you exercise along with it.

  20. Erica

    I am so sick of dieting. I’m going to start using Fenfast and that’s really the last resort for me. I’ve tried all the different programs but I just end up being hungry and giving up. So I’m counting on this pill to get me to where I need to be. It’s not that I’m not dedicated and I’m willing to work very hard, but I just can’t spend the next few months being hungry every single minute. The reviews for this all look really good and the ingredients make sense so I have my hopes up.

  21. Mimi

    Is there anything better than a non-prescription diet pill that works like a prescription diet pill? Not in my books there isn’t. In my experience Fenfast delivers on its promises. If you want something without all of the crazy side effects, you should totally give it a try.

  22. Robert Cadbury

    The practicality of this product is astounding. After using a bottle of the FenFast 375 tablets for one month – a period that I considered to be my own personal trial for the product before which I would purchase a larger quantity – I understood that the engineering of this formula was a true accomplishment. Its benefits are powerful and help to generate a considerable difference in weight loss abilities, but I couldn’t detect any harmful effects.

  23. Spring Tulip

    I’ve read that Fenfast is an alternative to some of the heavy prescription pills. Does that mean that it’s only right for people who would otherwise use those medications, or can I use it too since I just want to lose 10 pounds so I can look better? Anyone know?

    1. Ben looks better

      Spring Tulip, Fenfast isn’t just an alternative for those who would otherwise take prescription pills. It’s for those who want to lose weight, but who have a hard time achieving their goals because they struggle with hunger pangs or lack energy to exercise. That said, if you’re really not sure if it’s the right choice for you, there’s nothing wrong with erring on the side of caution and talking to your doc first to see what he/she thinks is good for you.

  24. Glen

    I’ve been using FenFast 375 for a total of 3 full weeks as of today. This has been revolutionary. Every spring I promise myself that I will get in shape by summer. Now I’m doing it and I have the extra energy to actually make a difference. I’m finally toning down that gut!

  25. Dave S.

    This is the first diet pill I’ve ever been able to commit to. I usually have such a hard time staying true to my weight loss goals because I rarely see any actual weight loss to help motivate me. FenFast has been a true inspiration for me. After the first week of taking it I lost 5 pounds! I’m on my third week and 15 pounds slimmer from when I started. This product is seriously amazing!

  26. StrawberryPie

    FenFast is way better than Phentermine. I’m so glad there is an OTC product that doesn’t come with all those scary side effects! Great product!

  27. Brenda B.

    This product is really good. Pros – it works fast, it supresses my hunger, it’s easy to take, and you lose weight. Cons – I still feel hungry at night. I don’t feel like I’m starving or anything, but I wish I wasn’t hungry at all. That said, I’ve lost a lot of weight and I’m happy 🙂

  28. Jen D

    I’m leaving a review for my boyfriend because he’s too much of a chicken to do it himself lol. I haven’t taken this diet pill, personally, but he has and it has done a lot for him. Not just in terms of his weight but also his self-esteem. I think he looks great. He’s lost 35 pounds already since taking it (I think…it’s been 2 months)and he doesn’t have any side effects. See Jon…was that so hard ;)xo

  29. DelDil

    I work out at 5am on mornings. When would be the best time to take Fenfast since I don’t eat that early but would like the energy boost? Is 430am fine to take it when my 1st meal may be at 6am? The instructions say 30 mins before meals so wanted to know if that’s a minimum time?

    1. Moderator

      @DelDil – You can take FenFast before you work out in the morning. It will give you added energy for making the most out of your workout. I would then repeat it 4 hours later. You can try taking it at different times too to see what works best for you.

  30. Trying

    I have been on meds for 3 weeks now and have lost only 6 pounds. I take the meds as directed and walk 45 min each night. am i doing something wrong that i am not losing the amount like others? i am not eating like i use to but still not seeming to get the results like others. are you able to take 6 tabs a day or 5 tabs a day for the extra boost? ia m feeeling great and cravings have slowed down but wasn’t sure if you can take 5 tabs a day or not?
