Putting on Weight from Tea and Coffee: Is It Possible?

Quick answer

• For most people, plain black tea and black coffee have negligible calories and are unlikely to cause weight gain on their own.
• Weight gain from coffee or tea typically comes from added sugar, cream, milk, syrups, and other calorie-dense additions.
• Consuming large quantities of even unsweetened beverages can contribute to overall calorie intake, which is the primary driver of weight gain.
• Certain herbal teas, especially those with added fruits or sweeteners, can contain calories.
• Caffeine in coffee and tea can temporarily boost metabolism, but this effect is usually minor and not enough to counteract significant calorie surplus.
• Focusing on the quality and preparation of your coffee and tea is more important for enjoyment than worrying about weight gain from the base beverage.

Key terms and definitions

• Calorie: A unit of energy. When we consume more calories than our body burns, the excess is stored as fat, leading to weight gain.
• Metabolism: The process by which your body converts what you eat and drink into energy.
• Sugar: A simple carbohydrate that adds calories and can contribute to weight gain when consumed in excess.
• Cream/Milk: Dairy or non-dairy products often added to coffee and tea, which contain calories from fat and/or sugar.
• Syrups: Sweetened flavorings often added to coffee drinks, which can significantly increase calorie and sugar content.
• Herbal Tea: A beverage made from the infusion or decoction of herbs, spices, fruits, or other plant material. Not technically “tea” from the Camellia sinensis plant.
• Caffeine: A stimulant found naturally in coffee and tea, known for its effects on alertness.
• Hydration: The process of providing or absorbing adequate fluids. Staying hydrated is important for overall health.
• Brewing Method: The technique used to extract flavor from coffee grounds or tea leaves (e.g., drip, pour-over, espresso, steeping).
• Calorie Deficit: Consuming fewer calories than your body expends, which is necessary for weight loss.

How it works

• The fundamental principle of weight gain is a calorie surplus: consuming more energy (calories) than your body uses.
• Plain black coffee and most unadulterated teas (from the Camellia sinensis plant, like green, black, oolong, white) contain very few, if any, calories.
• The body processes the calories from any food or beverage consumed. If these calories are not used for energy, they are stored.
• When calorie-rich additions like sugar, cream, whole milk, or flavored syrups are added to coffee or tea, the calorie count of the beverage increases dramatically.
• These added calories contribute to your daily total intake. If this total exceeds your body’s energy expenditure, weight gain can occur.
• Even large volumes of zero-calorie beverages can contribute to a feeling of fullness, potentially impacting overall food intake, though this is a secondary effect.
• Caffeine in coffee and tea can temporarily increase metabolic rate, meaning your body burns slightly more calories at rest. However, this effect is generally modest and unlikely to cause weight gain or loss on its own.
• Herbal teas can vary. Some are naturally calorie-free, while others might contain ingredients like dried fruit or added sweeteners that contribute calories.
• The process of digestion and absorption is how your body extracts nutrients and energy from what you consume, including beverages.
• Therefore, the impact on weight is almost entirely dependent on the total calorie content of what you drink, not just the base coffee or tea itself.

What affects the result

• Added Sugars: This is the most significant factor. A spoonful of sugar in your coffee or tea adds calories. A grande latte with caramel syrup can easily add hundreds of calories.
• Dairy and Non-Dairy Additives: Whole milk, half-and-half, heavy cream, and even some non-dairy milks (like oat or coconut milk, depending on preparation) contribute fat and/or sugar, thus calories.
• Flavored Syrups and Sauces: Many coffee shop beverages are loaded with calorie-dense syrups (vanilla, hazelnut, mocha) and sauces (caramel, chocolate).
• Portion Size: Drinking a large 20-ounce sweetened coffee drink will contribute more calories than a small 8-ounce cup of plain tea.
• Frequency of Consumption: Regularly consuming high-calorie coffee or tea drinks daily can lead to a consistent calorie surplus over time.
• Type of Tea: While black and green teas are low-calorie, some herbal blends, especially those marketed for flavor or wellness, might contain added sweeteners or calorie-contributing ingredients.
• Caffeine’s Metabolic Boost: While minor, caffeine can slightly increase your resting metabolic rate. However, this effect is usually too small to significantly impact weight on its own.
• Individual Metabolism: People have different metabolic rates, meaning they burn calories at different speeds. This influences how the body processes consumed calories.
• Overall Diet: Weight gain is a result of your total daily calorie intake from all sources. Coffee or tea is just one part of that equation.
• Hydration Needs: Sometimes, thirst can be mistaken for hunger. Ensuring adequate hydration with plain water can help manage overall calorie intake.
• Brewing Method (Indirectly): While the brewing method itself doesn’t add calories, it can influence how palatable the coffee or tea is, potentially affecting whether you feel the need to add calorie-rich ingredients.
• Sweeteners: Artificial sweeteners are often used as sugar substitutes. While they don’t add calories, their long-term impact on metabolism and appetite is still a subject of research.

Pros, cons, and when it matters

• Pros of Plain Coffee/Tea:
• Low to Zero Calories: Unsweetened black coffee and tea are virtually calorie-free, making them excellent choices for hydration without adding to your daily caloric intake.
• Hydration: They contribute to your daily fluid intake, which is essential for bodily functions.
• Antioxidants: Many teas, especially green and white varieties, are rich in antioxidants that can have health benefits.
• Metabolic Boost (Minor): Caffeine can provide a temporary, slight increase in metabolism.
• Enjoyment and Ritual: For many, a warm cup of coffee or tea is a cherished part of their day, offering comfort and a moment of pause.
• Cons of Coffee/Tea Additions:
• Significant Calorie Load: Sugars, creams, syrups, and flavored additions can turn a healthy beverage into a calorie bomb, contributing to weight gain.
• Sugar Intake: High sugar consumption is linked to various health issues, including weight gain, type 2 diabetes, and heart disease.
• Empty Calories: Many additions provide calories but little to no nutritional value.
• Digestive Issues: Some individuals may experience digestive upset from certain types of coffee or tea, or from the additives.
• Caffeine Sensitivity: Excessive caffeine can lead to jitters, anxiety, sleep disturbances, and digestive issues for sensitive individuals.
• When it Matters:
• Weight Management: If you are trying to lose or maintain weight, being mindful of what you add to your coffee and tea is crucial. Opting for plain versions or minimal, low-calorie additions is key.
