The Coca Cola Corporation has begun
a joint venture with the Nestle Corporation to produce
a new drink called Enviga. This green tea based beverage
is claimed to be a “negative calorie”
drink that will help burn calories. Enviga does have
calories, actually 5 per can. The “negative
calorie” claim must therefore be the belief
that the drinks will burn more calories than it provides.
Will the drink really help you lose weight though,
and at what cost?
The manufacturers of Enviga claim that drinking 3
cans of Enviga a day will burn 60 to 100 calories
per day. This is the equivalent number of calories
of the average éclair, one cup of fat free
ice cream, or 4 to 6 level teaspoons of sugar. In
terms of fat, this equates to the loss of about of
about 5 pounds over a year. Each can of Enviga costs
an average of $1.40. Therefore, to lose that 5 pounds,
if the drink really causes weight loss, would cost
On the other hand, drinking a cold glass of water
burns around 17 calories as the body burns calories
to warm the water. Therefore, drinking 8 sixteen ounce
glasses of cold water daily will burn 136 calories
daily. In addition, drinking water not only helps
to cleanse the system, but also suppresses the appetite.
Both help reduce weight. A brisk walk burns 7 calories
per minute. If it took 10 minutes to walk to the store
to buy the Enviga, you would burn 70 calories, and
another 70 calories on the way back. That is more
calories burnt than by drinking 3 cans of Enviga.
In addition, regular exercise helps to build muscle,
which burns fat even when in a resting state.
Calories are not the only cause of weight gain though.
So the real question is will Enviga help people lose
weight. In my opinion, no it will not help people
lose weight. In fact, it is more likely to cause weight
gain than weight loss. To understand why, we must
first look at the ingredients:
Carbonated water, calcium lactate, concentrated green
tea from tea leaves, citric acid, phosphoric acid,
potassium sorbate and potassium benzoate, natural
flavors, Aspartame, caffeine, Acesulfame-K.
The only ingredient in Enviga that will have any
real effect on weight loss is the green tea concentrate,
and the added caffeine. Catechins in green tea have
been found to help boost the metabolism, as does the
added caffeine, and the caffeine from the tea extract.
On the other hand, Enviga uses two artificial sweeteners,
Aspartame, and Acesulfame-K. Not getting in to the
other dangerous adverse effects of these two artificial
sweeteners, both Aspartame and Acesulfame-K cause
insulin spikes. Insulin in turn promotes fat production.
In addition, Aspartame is also well known for causing
weight gain because it promotes appetite. To further
compound the problem, Aspartame can cause dry mouth
syndrome increasing the likelihood that the person
would drink even more Aspartame containing beverages,
which can lead to further weight gain.
If you are really interested in losing weight, I
recommend staying away from diet sodas and other diet
drinks. Water is your best choice for a beverage,
especially if you are diabetic.
