Continue drinking!, If you did not know, I am currently in a caloric deficit or weight loss phase. That is, I am consuming fewer calories than I normally would, with the goal in mind to lose weight/lose fat. The other day I was consuming my favorite Coca-Cola Coke Zero beverage, zero calories, . As I took a sip a someone shouted, "those are bad for you!". I immediately slapped my hand on my forehead and shook my head. This person continued to mention the carcinogenic effects of artificial sweeteners. Firstly, it's out of the scope of this email to dive into that, however, just know it will take drinking nearly 3 dozen diet sodas a day for a long period of time to encounter any carcinogenic effects of artificial sweeteners. It's the dosage that matters!, ,
I thought I'd look into diet soda's and artificial sweeteners a bit more. I found something more extraordinary and practical. I found several studies examining the effects of diet beverages in comparison with water for weight loss.
When it comes to weight management, many people wonder if diet drinks really help. According to a diet soda and weight loss study, the evidence shows that diet beverages not only support reducing calories but also improve adherence to fat-loss plans.
Not only did researchers find that diet beverages help with weight loss, but they also help improve health markers such as blood pressure.
The big takeaway for me was not only do diet beverages help with reducing calories, they also promote long-term adherence. This could be for a myriad of reasons such as the variety of flavors and options (caffeinated or carbonated).
