Should I be concerned about Diet Coke and weight gain?

No. Diet Coke is a zero-sugar, zero-calorie cola.

We understand, though, if there are questions about a diet soda/weight gain link. What we’ve found is when you look at the mix of science and research on this topic, sugar substitutes, like the aspartame we use in Diet Coke, do not make you hungrier or cause weight gain.

In fact, sugar substitutes provide a sweet taste but have few or no calories. They can help you manage your calorie intake.

There’s lots of research around this question. To find out more, go here.


Is diet soda bad for you?

No. People around the world drink our diet sodas every day. They are a refreshing option for people who want to enjoy the sparkling taste of soda, but with fewer or no calories. That’s why the safety of our ingredients and beverages is really important to us. This includes the sugar substitutes like aspartame we use in our diet sodas. These are some of the most thoroughly researched ingredients in the world. In fact, science and health professional organizations have affirmed that sugar substitutes are safe. So have food safety authorities, like the FDA.


Why does The Coca-Cola Company use artificial sweeteners?

We use sugar substitutes because while sugar in moderation is fine, too much sugar isn’t good for anyone. It’s why we offer reduced- or no-sugar versions of many of the drinks you love. We want to give you great-tasting choices with fewer or no calories. We also use sugar substitutes because they are confirmed safe by the FDA and thoroughly tested in scientific studies.

How is The Coca-Cola Company reducing sugar?

We are reducing sugar and calories in our Coca-Cola products by:

1. Rethinking our recipes

We are reducing sugar in more than 500 of our drinks around the world.


2. Making more reduced- and no-sugar versions of many of the drinks you love available and making them easier to find

-    19 of our 21 top global brands have a reduced- or no-sugar option

-    Since 2014, we’ve launched nearly 500 new reduced- or no-sugar drinks globally

-    In the U.S., 250 of the 800+ beverages we offer are reduced- and no-sugar


3. Promoting our reduced- and no-sugar options more

We want to give you choices. So we’re advertising our no-sugar versions of Coca-Cola right next to the original Coca-Cola taste. Choose what suits you and your lifestyle and diet. We call this our “One Brand” global marketing strategy.


4. Exploring new sugar substitutes

We are using new sugar substitutes to make new drinks with fewer calories. Coca-Cola Life is one example. It is sweetened with a blend of cane sugar and Stevia leaf extract. It has 35% fewer calories and less sugar than Coca-Cola, but with a great taste people love.


5. Providing smaller, more convenient packaging

We have 7.5-oz mini soda cans and other smaller sizes to make it easier for you to reduce sugar. In fact, about 40% of our soft drinks come in these smaller sizes in the U.S.


6. Supporting limits to added sugar intake

Several leading health authorities, including the U.S. Food and Drug Administration and the U.S. Dietary Guidelines for Americans, say that children and adults should limit added sugar to no more than 10% of their total energy/calorie consumption.  


We call this Our Way Forward.
