When you introduce more micronutrients in your diet and high quality protein and fat, you give your liver the raw materials to create enzymes to metabolize and excrete toxins your body has been hanging on to for yearssss. If you smell bad, you need to sweat more. Imagine a dirty dry sponge, you soak it and wring it out over and over until it runs clear. These toxins are environmental but can also accumulate when food is digested poorly so being sure your bowel transit time is ~24 hrs (eat a bolus of something distinguishable like tomatoes with the skin and you can detect them in your stool and estimate time) and supplimenting with betaine HCL or digestive bitters or practicing mindful eating can stimulate digestive secretions and speed up bowel transit time. Ayurvedic herbs are exceptional in this regard to. Sarsaparilla is an herb I personally like for increasing sweating and simultaneously absorbing toxins in the colon. food grade diatomaceous earth is also lovely for mopping up extra garbage in your tubes the morning after a late meal, it has a huge surface area and is able to mop up bacteria and even weaken the outer membrane of parasites so your immune system can dissolve them.
By far the most easy effective thing to reduce your odor would be to do an infared sauna followed by a cold shower, or hot exercise followed by an ice bath. This will squeeze days worth of gunk out of your skin in a few minutes and you will glow physically and metaphorically.
Hope this information finds you well! OH also one of my favorite things is to take a whole onion, any kind, and chop it up with your choice of oil, turmeric, pepper (improve absorption of turmeric into cells), ACV, and some raw honey. Maybe some cayenne if I really want to warm up :)
