Metabolism is not fixed. While genetics play a role, multiple well-studied ingredients and lifestyle factors have demonstrated measurable effects on resting metabolic rate and fat oxidation. You do not need to starve yourself or spend two hours at the gym.
What Metabolism Actually Is
Metabolism refers to all chemical processes that convert food into energy. Resting Metabolic Rate (RMR) — the calories burned at rest — accounts for 60–75% of total daily energy expenditure for most people. Increasing RMR even slightly has a compounding effect on fat loss over time.
Three mechanisms drive metabolic rate: thermogenesis (heat production from fat oxidation), mitochondrial efficiency (how well cells convert fuel to energy), and lean muscle mass (muscle burns more calories at rest than fat). Targeting all three simultaneously produces better outcomes than any single approach.
The Ingredients With the Best Evidence
Green Tea Extract: thermogenesis
Green Tea Extract is the most studied thermogenic compound available. A 2000 meta-analysis in the American Journal of Clinical Nutrition found that Green Tea Extract significantly increased 24-hour energy expenditure and fat oxidation compared to placebo. The mechanism is catechin-EGCG inhibition of catechol-O-methyltransferase (COMT), which extends the thermogenic effect of norepinephrine. In practical terms, it raises resting calorie burn without stimulant side effects.
L-Carnitine: fat transport
L-Carnitine is the molecule responsible for transporting long-chain fatty acids across the mitochondrial membrane to be burned as fuel. Without adequate L-Carnitine, fatty acids cannot enter the mitochondria and are stored instead. A 2020 systematic review in Obesity Reviews found that L-Carnitine supplementation produced significant reductions in body weight and fat mass, with greatest effects in individuals who were overweight or had low baseline L-Carnitine levels — common in people who eat little red meat.
Coffee Mix: sustained thermogenesis
Caffeine is the most widely consumed thermogenic compound in the world. A 2019 study in Scientific Reports found that caffeine intake was significantly associated with reduced body fat percentage and BMI in population-level data. The mechanism combines thermogenesis (increased heat production) with lipolysis (release of stored fat into circulation for use as fuel). Coffee Mix in Glowming Café Latte provides this effect alongside L-Carnitine, creating a paired fat-release and fat-burn mechanism.
What Kills Metabolism
- Extreme calorie restriction — triggers adaptive thermogenesis (the body lowers RMR to conserve energy)
- Skipping protein — muscle is metabolically active; losing muscle mass reduces RMR permanently
- Poor sleep — growth hormone, which drives muscle repair and fat oxidation, is released primarily during deep sleep
- Chronic stress — sustained high cortisol promotes fat storage, particularly visceral fat
Green Tea Extract and L-Carnitine in Glowming Café Latte
Glowming Café Latte combines L-Carnitine, Green Tea Extract, and Coffee Mix in one morning sachet — a thermogenic and fat-transport stack designed to raise metabolic rate and fat oxidation during the most metabolically active part of the day. It replaces your morning coffee with a formula that does more than just wake you up.
“I have tried every diet going. What I never did was address my actual metabolism. The Café Latte gives me energy without the jitteriness of strong coffee and I have dropped 6kg in two months without going to a gym once. I just walk 30 minutes a day.”

Frequently Asked Questions
Can you permanently increase your metabolism?
Yes, through increasing lean muscle mass — the most durable way to raise RMR. Thermogenic ingredients like Green Tea Extract and caffeine raise metabolism while they are active in the body. Building muscle provides a permanent baseline increase. The combination of thermogenic supplementation and resistance training produces the best long-term results.
Does eating small meals frequently boost metabolism?
The evidence for meal frequency affecting metabolism is weak. Total daily caloric intake and macronutrient composition matter more than timing. However, eating protein at every meal does support muscle protein synthesis, which protects lean mass during caloric restriction.
How long does Green Tea Extract take to work?
Acute thermogenic effects from Green Tea Extract occur within 2–3 hours of ingestion. Measurable changes in body composition require consistent daily use over 8–12 weeks, consistent with the timelines in clinical research.
Is L-Carnitine a stimulant?
No. L-Carnitine has no stimulant properties. It works by improving the transport of fatty acids into mitochondria for energy production. It can be taken at any time of day without affecting sleep, unlike caffeine-containing thermogenics.
