Easy Lifestyle Tweaks to Improve Your Metabolism

21. Adding More Fermented Foods

Fermented foods like kimchi, sauerkraut, kefir, and miso are loaded with probiotics that nourish your gut microbiome—a key player in regulating metabolism and fat storage. A diverse and healthy gut population can influence how your body extracts energy from food, manages blood sugar, and handles inflammation. Including fermented foods in your meals supports metabolic health from the inside out.

22. Practicing Time-Restricted Eating (TRE)

A close cousin to intermittent fasting, time-restricted eating (TRE) focuses more on when you eat rather than what you eat. For example, you might limit food intake to an 8- to 10-hour window each day. This gives your body a longer overnight fasting period, which research suggests may improve insulin sensitivity, support fat burning, and help synchronize your metabolism with natural circadian rhythms. TRE is simple to implement and can lead to surprising benefits without major dietary overhauls.
