Want to boost your energy and maintain a healthy weight? Here’s how to use diet to kick-start your metabolism with these 10 metabolism boosting fermented foods.
What affects your metabolism?
Metabolic rate is influenced by a number of factors:
- Age: Metabolic rate generally peaks at about 10 years old. After that it continues to drop with age. So the older you are, the slower your is metabolism.
- Gender: Testosterone increases metabolism, so males usually have a higher metabolic rate than females.
- Exercise: Regular, strenuous exercise will increase your metabolic rate. So if you want to boost your metabolism, start exercising for at least 30 minutes a day.
- Diet: A healthy microbiome diet will naturally increase metabolic rate.
Metabolism Boosting Diet
It is possible to boost your metabolism by following a simple and healthy diet. Here’s some diet changes that can kick-start your metabolism:
- Eat protein: Protein requires more energy to digest, so it naturally boosts your metabolism.
- Avoid sugar: Sugar decreases your metabolism, even if it is consumed with protein. So swap sugar and other sweeteners for naturally sweet fruit.
- Regular meals: Fasting lowers your metabolic rate. It’s better to eat 5 small, healthy meals a day than 1 large meal.
- Healthy microbiome: Healthy gut bacteria is linked to a faster metabolism. So eat lots of fiber and fermented foods to feed your microbiome.
- Certain foods, including: hot peppers, apple cider vinegar, coconut oil and ginger have been shown to help with weight-loss and increase metabolism.

hi Emillie-
Thanks for your expertise and heart as a fermentation enthusiast!
Quick question: can I use pickle juice as a starter culture for the fermented egg recipe on your site? I made the pickles myself– they are naturally lacto-fermented of course : ). I may have stuck my hand in the jar once or twice, but the ferment is nice thick and cloudy. I do have some Bragg’s ACV — would that work?
thanks again for your time and lovely website!
You can use the pickle juice or Bragg’s ACV. They both should work fine. I haven’t tried cucumber pickle juice, (just other vegetables) but it sounds yummy. Bragg’s is great for fermenting. Enjoy!
Hi Emilie, could you please develop what you hear by ”metabolic rate” and what does it engage, when you write ”Testosterone increases metabolism”. Thank you so much. Lucas
Hi Lucas, my background is more neuroscience… but I’ll see what I can do to answer your questions. Metabolic rate is the amount of energy we use over time. This can be measured in the amount of calories burned, oxygen consumed, etc. For example, your resting metabolic rate is lower than when you’re exercising.
In terms of daily life, our metabolic rate relates to how much energy we have, weight gain, whether we are usually hot or cold, etc. Testosterone is a hormone that naturally increases the metabolic rate. It’s why men usually run warmer than women. Cheers, Emillie
