How to Reboot Your Metabolism After 40

July 5, 2022

If you’re over 40, and you’ve been struggling with your expanding waistline, no matter how much (or how little) you’re eating, your fat may not be your fault. Your stalled weight loss is not the result of simply too much food and too little exercise. There’s more to the metabolic math going on with your body than the equation of calories in + calories out = weight loss or gain.

This is the reason I dug deep into the research and wrote my Radical Metabolism plan. After working with thousands of women with a sluggish metabolism, finding the weight creeping up on the scale despite their best efforts, the pieces of the puzzle finally came together for me. I came to the realization that we need to look at the cellular level to find true health and effective, lasting weight loss.

A healthy metabolism needs healthy cells, and when your cells are full of environmental toxins and stored emotions and traumas, their energy production is affected. They become bogged down and stall your metabolism until it becomes sluggish. Top that off with a diet void of nourishing essential fats, the necessary building blocks of a healthy cell, and it’s easy to see how disease can move into these weakened cells and further affect metabolism.

The good news is that I’ve found proven ways to flush these toxins from your system, feed your cells what they crave, and supercharge your metabolism! Let’s look at my “Radical Rules” and “Metabolic Menders” to help you achieve healthy, lasting weight loss. It’s time to get your energy back and feel good looking in the mirror again!

A Delicious Way to Speed Metabolism

Your morning cup of coffee can actually help you lose weight — especially if you choose a light to medium roast! Coffee’s secret weapon is chlorogenic acid, a compound that instructs fat cells to burn stored fat for fuel, balances blood sugar and dials back cravings. Chlorogenic acid typically burns off during roasting, so lighter roasts are more effective than darker roasts. 

To maximize the metabolism-revving benefits of chlorogenic acid, sip 1 to 2 cups organic coffee daily. The only coffee I recommend is Purity Coffee — it is lab-tested to be 2x to 10x times higher in antioxidants and free of molds, pesticides, and mycotoxins.

Tip: If caffeine doesn’t agree with you, three cups of decaf deliver the same benefits!

This Melts Your Menopot Faster Than Just About Anything Else!


When I was writing my book Radical Metabolism I wanted to look at all the latest research about how to dissolve and dissipate a “menopot”. You see, at 50 years and above I’ve been very concerned about the little pooch that I have grown from year to year and wanted to find something rather radical and quick that would make it go away. 

And low and behold, I looked at the extract of an African mango seed extract known as irvingia and found that it was one of the most successful natural agents known to man in terms of targeting the menopot that so many of us 50 and beyond are seeming to exhibit in this day and time.

    I heard that Cilantro can be too strong of a detoxing agent for those with autoimmune issues? Also, do you have a blog post on hormone supplements to use for menopause? Both of my doctors are saying I cannot take bio-identical hormones with an autoimmune disease. Now trying to figure out what I am going to take. Thank you. Cindy

      Hi Cindy – Please give my team a call at UNI KEY and they can help you address this. We offer hormone testing and have a staff nutritionist available. I would also recommend looking for a functional doctor to work with vs. traditional — it is so helpful when navigating something like an autoimmune concern.
