Rev Up Your Engine: 5 Easy Ways to Increase Metabolism in Just 5 Days

Are you feeling sluggish? Are you eating healthy but the scale won't budge? The secret might not be what you’re eating, but how your body processes it. Your metabolism is the chemical engine that keeps you alive, and while genetics play a role, you can "nudge" it into high gear with a few strategic shifts.

If you want to feel lighter and more energetic, here are five scientifically-backed, easy ways to increase your metabolism in 5 days.


1. Prioritize "Liquid Fire" (Water & Green Tea)

Hydration is the simplest way to speed up calorie burning.

  • The 5-Day Challenge: Drink 500ml of water 30 minutes before every meal.
  • Why it works: Studies show that drinking water increases resting metabolism by 10–30% for about an hour.
  • The Power Up: Swap one coffee for Green Tea or Oolong Tea. These contain catechins that help the body turn stored fat into free fatty acids, increasing fat burning by nearly 4–5%.

2. Master "NEAT" Movements

You don’t need a 2-hour gym session to see results. NEAT (Non-Exercise Activity Thermogenesis) refers to the energy expended for everything we do that isn't sleeping, eating, or sports-like exercise.

  • The 5-Day Challenge: Stand up every 30 minutes. Take the stairs instead of the elevator. Pace while you are on phone calls.
  • Why it works: Sitting for long periods shuts down an enzyme called lipase, which helps break down fat. Frequent movement keeps your metabolic rate elevated throughout the day.

3. Feast on Protein (The Thermic Effect)

Every time you eat, your metabolism rises to digest the food. This is called the Thermic Effect of Food (TEF).

  • The 5-Day Challenge: Ensure every meal contains a protein source (eggs, lentils, Greek yogurt, or lean meat).
  • Why it works: Protein causes the largest rise in TEF. It takes 20–30% of its usable energy just to digest it, compared to 5–10% for carbs and 0–3% for fats.

4. Try High-Intensity "Micro-Bursts"

If you have 10 minutes, you have enough time to boost your metabolism for the next 24 hours.

  • The 5-Day Challenge: Perform 4 minutes of Tabata or HIIT (High-Intensity Interval Training) daily. Think 20 seconds of jumping jacks followed by 10 seconds of rest.
  • Why it works: This creates "Afterburn" (EPOC—Excess Post-exercise Oxygen Consumption). Your body continues to burn calories at a higher rate even while you’re sitting on the couch later.

5. Prioritize "Metabolic Sleep"

Sleep deprivation is a metabolism killer. It messes with your hunger hormones, ghrelin and leptin.

  • The 5-Day Challenge: Get exactly 7–8 hours of sleep and keep your room cool (around 18°C).
  • Why it works: Research suggests that sleeping in a cooler room may stimulate "brown fat" production—a type of fat that burns calories to generate heat.
