Not a week goes by where the weight loss and diet industry doesn’t release new fat burners with huge marketing campaigns.

These are often promoted by celebrities as the secret to losing weight with minimum effort.

While fat-burning supplements like that almost never work, there are some that have a proven track record with scientific research backing their ingredients.

I tested dozens of these products and came up with a list of five that have the best effects.

1. LeanBean

The weight-loss supplement that we have found to work best for women is called LeanBean. And the best thing about it is that the formula has been designed specifically for women.

It also doesn’t contain large doses of caffeine that can make you jittery and lose sleep. Instead, it relies on green tea extract for a thermogenic boost.

It also has a good dose of vitamins to help with your overall health and wellbeing, as well as antioxidants to deal with toxins released from the fat you lose.

Pros

• Limited caffeine dose from green tea extract
• Positive reviews about effective fat burning
• Comes with a great money-back guarantee for a risk-free trial

Cons

• You’ll need to remember to take this several times a day

2. PhenQ

PhenQ is another good over the counter natural phentermine diet pill alternative for men and women, even though it doesn’t have the same female formula as LeanBean. But the ingredients aren’t too strong, and it should be easy to adjust the number of capsules you take.

This fat-burning supplement also seems to work well for better mental and physical energy, as many women say that it helps them get through a busy family and work life.

Pros

• Positive reviews about the fat-burning ingredients being fast to work
• Provides good mental focus and motivation
• Should help with improved energy levels throughout the day

Cons

• High caffeine dose might cause some jitters if you’re sensitive to stimulants

3. Instant Knockout

Instant Knockout is a stronger fat burner, at least from a caffeine perspective. That’s not generally a negative thing, as it should help to significantly boost your metabolism.

But you do need to consider this if you’re going to take it later in the day, as it might mess up your sleep.

When combined with the right diet and exercise routine, it also claims to help with retaining more muscle mass, which should lead to a leaner appearance.

Pros

• Strong caffeine dose for a thermogenic and mental boost
• Helps to maintain muscle fibres for more effective strength-building
• Positive reviews about appetite suppression

Cons

• Not a vegan-suitable option

Powher Fat Burner

Here’s another fat burner specifically formulated with women in mind so that you can avoid having to work out smaller doses for your body size.

Powher seems to work particularly well for appetite suppression and helping you avoid reaching for the snack drawer in a moment of weakness.

That also makes it an ideal fat-burning supplement to support you through extended fasting periods.

Pros

• Good ingredients to help with hunger cravings
• Suitable for vegans with only natural plant ingredients
• Available with a money-back guarantee to make it a risk-free trial

Cons

• Moderate caffeine dose might be a bit low for some women

5. Lean-XT

The final fat burner that we’ve seen good results for in women is Lean-XT. It’s popular with women who want to take a single daily dose rather than having to remember multiple capsules a day.

If you’ve had some jitters from stimulants in fat-burning products before, then this might be the ideal solution as it doesn’t contain caffeine.

And with the added cayenne pepper, you’ll enable your metabolism to burn fat more effectively as well as absorb the ingredients faster.

Pros

• Single daily dose makes it easier to remember
• Caffeine-free option for women who are sensitive to stimulants
• Added cayenne pepper stimulates digestion and metabolism

Cons

• No bulk order discounts available

How do fat burners for women work?

Fat burners work by triggering natural processes in your body that we have summarised in simple terms.

• Metabolic effect. Natural fat burners aim to trigger metabolic processes that help you burn off more calories and fat. To be more precise, a thermogenic fat burner may result in your body slightly raising its core temperature. And to fuel that process, it burns off more calories from food and stored body fat. It’s not a magic weight-loss pill, as women still have to stick with a healthy diet and an active workout routine for these fat-burning supplements to work.
• Appetite suppression. The other thing that fat burners aim to help with is reducing those hunger cravings that you get from a calorie-deficient diet. We’ve found that most people who fail to lose weight tend to reach for snacks in between meals. And those are often sugary treats that just pile the fat back on and cause all sorts of issues for your blood sugar levels. With carefully chosen fat burners, you should be able to bridge those gaps between meals without having to use too much willpower.

Are you going to boost your fat loss efforts?

Whether you’re in a cutting phase for strength building or you just want to lose some love handles, we think the best fat burner that women could invest in is LeanBean.

Of all the fat burners we tried, it had the most optimal formula without relying on heavy doses of stimulants.

And while you burn fat more efficiently, you’ll also notice that you don’t feel hungry in between your meals.
