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. W ill 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 $1,533.00.
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 it also suppresses the appetite. Both of these will 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 and Acesulfame-K.
The only ingredients in Enviga that will have any real effect on weight loss are the green tea concentrate and added caffeine. Catechins in green tea have been found to help boost the metabolism. as does the added caffeine and the additional 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. This is especially true if you are diabetic.
