The Best Weight-Loss Drink Mixes

When it comes to weight-loss diets, diet drink mixes can be a good choice if you're looking for a simple plan. On these diets, you typically replace two regular meals with a diet drink and eat one healthy meal each day.

The best weight-loss drink mixes should provide enough calories that you're not consuming too little and should come fortified with vitamins and minerals so that you meet your daily vitamin and mineral needs. Experiment with different blends to find one that meets your needs and tastes great. Consult your doctor to help you determine a good weight-loss plan for you.

While diet drink powders are a good way to help you reduce your calorie intake to lose weight, these types of diets do not teach you how to control calories to keep the weight off when you go back to eating regular food. Finding meal replacement plans that offer assistance with eating after the diet is a good place to start, such as the Medifast plan 56. You can also talk to your doctor or a dietitian for advice.
