When you consume enough calories to lose weight but drink alcohol, soda, sweet tea, juice, etc., those liquid calories still count even if they don't fill you up. These calories are either keeping you from losing weight or causing you to gain weight. People underestimate the number of calories in a 44-ounce cup, Natasha explains. I was disgusted when I found I was drinking nearly 3,000 calories in Coke every day. Worse, the calories you ingest have little influence on your hunger. You don't even realize if you ingest an extra 200 calories during your dinner. You don't feel any fuller or more content than if you'd simply sipped a glass of zero-calorie water.
