Things you think will boost your metabolism….. 💊
You often hear people claiming various foods/diets/workouts etc will ‘boost your metabolism’ but sadly there’s actually very little scientific evidence many do.
Despite many claims that intermittent fasting, or 24 hour (and longer) fasts will boost your metabolism the reality is they don’t. Research suggests that fasting has the same or negative effects on metabolism compared to a calorie deficit from other ‘diets’. When you severely limit calories, your body slows down basic functions to conserve energy. Instead of boosting your metabolism, you may experience a reeducation of to 20% your BMR.
Supplements don’t boost your metabolism – some containing stimulants may temporarily increase metabolism (3-4%) but this diminishes with time and use. Avoiding carbs, eating multiple small meals, drinking lemon water/coconut oil or a detox/juice cleanse have little to no impact and no studies support their claims to increase metabolism. I’ve discussed fasted cardio/exercise before as it’s often touted to burn more fat/boost metabolism. It does neither – but from a workout perspective if you haven’t eaten then you may fatigue faster and be unable to work as hard, therefore burning fewer calories.
Things that are scientifically proven to increase your metabolism include regular exercise and building lean muscle. Eating enough protein, which has a thermic effect when digested (though only accounts for 10% of total energy expenditure). Eating a high fibre diet which requires energy to digest and can help regulate blood sugar. Staying hydrated – being dehydrated reduces BMR. Getting enough sleep to avoid a drop in metabolism and managing stress. Increasing NEAT (Non-Exercise Activity
Thermogenesis) which accounts for 15% – 50% of total energy expenditure through everyday activities such as, standing, walking, cleaning, moving around etc.
Most of these have only a minimal impact (as discussed before), so really the most significant impact on metabolism is to avoid being sedentary and to move more throughout the day. So avoid those expensive supplements and fad diets/exercise trends and stick to the basics!
