text: i need to know a diet in which i can still have my glass of red wine in the evenings.?   count your calories. yes, it sounds old fashioned, but that really is the best way. remember what a calorie is--energy! measure the energy in and make sure that the energy that goes out is higher. for me, about 1900 calories a day is maintenance weight, meaning that the calories in=calories out. my dieting calorie count is 1500. you need to have a daily calorie target, but you can be slightly over or under each day. small fluctuations don't hurt anything. for me, i always craved a beer, a glass of wine, and/or a snack about 9 pm. now, i have just one of those things, and that's the only thing (with calories) i eat or drink after dinner. drink lots of water, eat breakfast, and watch your portion control! make sure that you eat a balanced diet--the food you eat needs to count nutritionally.
