If you're a woman struggling to get rid of stubborn belly fat or shed a few pounds, you know that it can be a frustrating process. Scientific studies have shown that men tend to lose significantly more weight in less time than women when undergoing weight-loss interventions. It doesn't seem fair.

But if women hold onto weight differently, why aren't there gender-specific products for weight loss? Well, there are. Several weight-loss supplement manufacturers gear their products toward women – but what each offers is quite different.

We recently tested Hourglass Fit, a metabolism-boosting fat burner supplement that's caffeine-free and explicitly designed for women. Could Hourglass Fit help to reduce your cravings and burn away body fat? Read our full review for all the details.

Why you should trust us

Over the past two decades, Innerbody Research has helped tens of millions of readers make more informed decisions involving staying healthy and living healthier lifestyles.

We evaluate products and services based on their adherence to quality, the latest medical evidence and health standards, and a simple question: would we buy the product or service ourselves if it weren't part of our job, and would we recommend it to family and friends?

Additionally, like all health-related content on this website, this review was thoroughly vetted by one or more members of our Medical Review Board for accuracy.

What is Hourglass Fit?

Hourglass Fit is a fat-burning supplement designed specifically for women's needs. This metabolism-boosting capsule supplement works in three ways to help women on their weight loss journeys. It assists in:

  • Curbing cravings with appetite-suppressing components like glucomannan and piperine.
  • Reducing calorie consumption and helping burn the calories you do consume.
  • Boosting energy to give you longer, more productive workouts.

Does Hourglass Fit work?

We found Hourglass Fit effective in suppressing our appetites while naturally boosting energy. We didn't get the jitters as we have with some caffeinated brands we've tested in the past, yet we felt an overall boost throughout the day without crashes.

In addition, we appreciated the mood-enhancing benefits of Hourglass fit, which helped inspire us on our fitness journeys. We worked out longer, indulged in fewer mid-afternoon snacks, and generally felt happier and more energized.

How Hourglass Fit works

Hourglass Fit combines several appetite-suppressing ingredients and thermogenic components like capsaicin to help curb cravings and burn fat faster. You take one capsule four times daily with a full glass of water. The company recommends taking each dose about 30 minutes before mealtimes.

We took one capsule each morning before breakfast, two before lunch, and one before dinner during our testing. After waiting 30 minutes, our appetites diminished significantly, causing us to eat less and snack less between meals. Below, we'll look at the science behind Hourglass Fit's ingredients and how they can help you shed pounds.


Glucomannan is a common ingredient in weight-loss supplements based on its appetite-suppression capabilities. This natural botanical derived from the rhizome of the konjac plant is water-soluble and expands in the stomach, giving you the sensation of fullness and quelling sugary cravings.

Researchers have conducted many studies and meta-analyses on glucomannan's use as an obesity treatment with varied results. Still, it shows potential in promoting weight loss and improving lipid and lipoprotein parameters. Hourglass Fit provides 3,000mg in each daily serving.


5-hydroxytryptophan (5-HTP) is a byproduct of L-tryptophan, a protein-building block. This naturally occurring amino acid promotes serotonin production in the body, leading to:

  • Improved sleep
  • Reduced appetite
  • Lessened anxiety and depression

Preliminary studies investigating 5-HTP as a potential treatment for obesity based on its impacts on satiety are underway, but this 2011 study indicates that 5-HTP effectively produced satiety among female subjects and helped reduce BMI.

Vitamin B2

In scientific studies, B vitamins have demonstrated their capacity to lessen fatigue and improve cognitive functioning. Some animal studies have linked them to a reduction in body weight gain and plasma levels of lipids.

Vitamin B2, also known as riboflavin, supports cell growth, development, and function in the body and helps transform food into energy. Vitamin B2 occurs naturally in green vegetables like spinach and asparagus and in eggs, organ meats, meats, dairy products, and fortified grains.

Vitamin B6

Vitamin B6 is intrinsically tied to metabolism, and its supplementation has shown many health benefits, including:

  • Reducing cardiovascular disease
  • Helping prevent cancer
  • Improving cognitive function
  • Diminishing PMS symptoms

Vitamin B6 is safe to take, and over-supplementation is rare, but it can interact with certain medications, including:

  • Cycloserine
  • Some epilepsy drugs
  • Theophylline

Vitamin B12

Vitamin B12 assists in the healthy development and upkeep of DNA and the blood and nerve cells of the body. You'll find vitamin B12 naturally in meats, fish, eggs, dairy products, breakfast cereals, and other fortified products.

Hourglass Fit includes vitamin B12 primarily for its mood-enhancing qualities and promoting energy and endurance. Vitamin B12 has a minimal risk of overdose and may help prevent heart disease and stroke.


Chromium is a compound often found in supplements for its potential in treating Type-2 diabetes and promoting weight loss. This chemical element is known for its role in insulin production and regulation and exists in some meats, fruits, and vegetables in trace amounts.

A 2013 meta-analysis on chromium supplementation for overweight and obese subjects demonstrated a relatively small reduction in body weight. This 1998 study showed that chromium could positively impact body composition when combined with a well-balanced diet and exercise.


Zinc, an essential trace element required for the function of enzymes and DNA and RNA metabolism, occurs naturally in meats, seafood, nuts, beans, and dairy products. Scientific studies have demonstrated that zinc supplementation alongside a restricted-calorie diet can suppress the appetite and may effectively treat obesity.


Capsimax is a proprietary derivative of cayenne peppers that involves OmniBead technology to extract capsaicinoids from vegetables without their accompanying heat. Capsaicin, the primary component in cayenne peppers, is a well-researched thermogenic, meaning that it can enhance metabolism and help lower body fat.


Bioperine is another proprietary extract — this one derived from black pepper. Piperine, the primary component of black pepper, helps with the absorption of nutrients and has demonstrated potential in scientific trials for lowering:

  • Bodyweight
  • Total cholesterol
  • Fat mass
  • Triglycerides

Is Hourglass Fit safe?

Hourglass Fit is safe for adults 18 and over, and men can take the supplement, as well. We advise avoiding fat-burning supplements entirely if you're pregnant or nursing. If you have any chronic medical conditions or take medications, you should consult with your doctor before beginning any new dietary supplement. Some ingredients in Hourglass Fit may interfere with medications or food allergies.


While Hourglass Fit does not provide a subscription membership, purchasing in bulk does earn savings. If you buy the Ultimate Slim package ($180), you'll receive one free bottle, dropping your cost to just $1.50 per day.

How we evaluate health products and services

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service or product. But in general, for health products and services, we have five broad areas that we explore in our evaluations, including:

Quality: How well does the company deliver its core service(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telemedical or teletherapy services, is the quality of the service high enough that we would recommend it to loved ones without hesitation? If not, why not? For health products, does the product or device meet a high level of safety? Is it manufactured with high-quality standards? Has it -- or have its ingredients – been subjected to studies that confirm effectiveness?

User-friendly: How intuitive and convenient is the service or product? Does the device, program, app, or website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money's worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure? Does a company market your information?

Customer support: Particularly in situations where 'one size fits all' doesn't make sense, how well does the company help make the service or product ideal for you or address your individual needs?
