Metabolism Booster: Best Foods, Drinks & Supplements to Speed Up Metabolism UK 2026

🔥 What Is Metabolism?

Metabolism is the process your body uses to convert food into energy. Your metabolic rate determines how many calories you burn at rest and during activity.

Types of Metabolism:

• Basal Metabolic Rate (BMR): Calories burned at rest (60-75% of total)
• Thermic Effect of Food: Calories burned digesting food (10%)
• Activity Thermogenesis: Calories burned during exercise and movement (15-30%)

Fast vs Slow Metabolism:

A fast metabolism burns more calories at rest, making weight loss easier. A slow metabolism burns fewer calories, making weight gain more likely.

Foods That Boost Metabolism

Certain foods naturally boost your metabolism by increasing thermogenesis (heat production) and energy expenditure:

1. Protein-Rich Foods
Protein has the highest thermic effect of all macronutrients - your body burns 20-30% of protein calories just digesting it.

Best Protein Foods for Metabolism:
• Chicken breast (31g protein per 100g)
• Eggs (6g protein each)
• Formula 1 Shakes (18g protein per serving)
• Greek yogurt (10g protein per 100g)
• Lean beef (26g protein per 100g)

2. Spicy Foods
Capsaicin in chilli peppers increases metabolism and fat burning.

• Chilli peppers
• Cayenne pepper
• Jalapeños
• Hot sauce

3. Green Tea & Coffee
Caffeine and EGCG (in green tea) boost metabolism by 3-11%.

• Instant Herbal Beverage (contains green tea)
• Green tea
• Black coffee
• Lift Off Energy Drink (contains caffeine)

4. Whole Grains
Your body burns more calories digesting whole grains than refined grains.

• Oats
• Brown rice
• Quinoa
• Whole wheat bread

5. Ginger
Ginger increases thermogenesis and reduces hunger.

How to Speed Up Metabolism

Here are proven ways to speed up your metabolism naturally:

1. Eat More Protein
Protein increases metabolism by 15-30% for several hours after eating. Aim for 1.6-2.2g per kg body weight daily.

2. Drink Cold Water
Drinking 500ml of cold water increases metabolism by 10-30% for 1 hour. Your body burns calories heating the water to body temperature.

3. Do High-Intensity Exercise
HIIT (High-Intensity Interval Training) boosts metabolism for up to 24 hours after exercise.

4. Build Muscle
Muscle burns more calories at rest than fat. Strength training 2-3 times per week increases resting metabolic rate.

5. Drink Green Tea or Coffee
Caffeine boosts metabolism by 3-11%. Our Instant Herbal Beverage contains green tea extract for metabolism support.

6. Get Enough Sleep
Poor sleep slows metabolism and increases hunger hormones. Aim for 7-9 hours per night.

7. Stand More
Standing burns 50 more calories per hour than sitting. Use a standing desk or take regular breaks.

8. Eat Spicy Foods
Capsaicin in chilli peppers increases metabolism and fat burning.
