Best Waist Trimmer for Lower Belly Fat in 2022

Last winter, I decided that I no longer wanted flabby granny arms and went on a full-fledged G.I. Jane style arms and shoulder workout routine. By the time spring rolled around, I had arms that would even make Ronda Rousey envious.

Unfortunately, I had ignored other parts of my body that would make me swimsuit ready, specifically my stomach. Something needed to be done quickly. I remembered that I had purchased a waist trimmer a few years ago.

After locating it in the back of my closet, I put it on during my workout at the gym. I soon learned that was a bad idea as this thing was bulky and clearly noticeable under my shirt. I had to find the best waist trimmer for under clothes so that complete strangers weren’t all up in my business.


As I began my search I was under no illusion that solely wearing a waist trimmer would give me the flat belly that I sought. I didn’t always have the belly of a woman in the 2nd trimester of her pregnancy so I knew that I needed to do a combination of things along with wearing a waist trimmer to get my desired physique.

Along with wearing your waist trimmer it is also imperative to bump up your metabolism in order to burn belly fat at longer intervals. Some of the below have proven to be effective ways:

  1. Say it all together now: “Abs are made in the kitchen“. The best way to burn calories 24-7 is by having a diet that combines lean protein, good fats and green leafy veggies in order to boost your metabolism.
  2. Incorporating cardio workouts into your exercise routine are significantly effective in reducing belly fat. Cardio or aerobic exercises also assist with fat burning by boosting metabolism.
  3. You need to stay well-hydrated. It is recommended to drink between 34-68 ounces of water per day in order to temporarily increase metabolism, assist in fat burning and to rid the body of waste.

How Exactly Do Waist Trimmer Belts Work?

The waist trimmer works as a wide, stretchable belt that goes around the abdominal area. This allows the body to sweat off excess water from the belly area which has a detoxifying effect.

The sweating is a result of the heating up of the abdominal area caused by wearing of the trimmer. As the body works to balance the body’s temperature, extra calories are also burned which assists in overall weight loss.

Back Support

One of the best waist trimmer belts for lower belly fat will also give you the benefit of supporting your back. As the trimmer goes around the waist this makes it beneficial in correcting posture.

Those suffering from back issues and pain can benefit from wearing a waist trimmer as the extra support relieves some of the pressure from your back.

Here are some of the most commonly asked questions about waist trimmers:

How long do you have to wear a waist trimmer to see results?

Results are dependent on your diet and exercise regime. The waist trimmer alone will not guarantee six pack abs but is rather meant to supplement your workout. With the right combination you should expect to see results within 2 weeks.

How often does a waist trimmer need to be washed?

As the best waist trimmer belt for under clothes will help you with working up a good sweat, it will be drenched after wearing it. It is recommended to lay it out unfolded and let it air dry after each wear. It should be wiped down with an antibacterial wipe or mild soap at least once a week if worn everyday.

Can the waist trimmer be worn all day?

It is only recommended to wear waist trimmer belts for a few hours a day. They are best used during exercise. While there is certainly no long term harm in wearing one all day it may irritate your skin and will likely become uncomfortable.
