Nestle's Ovaltine chocolate drink can be a part of your diet as you attempt to lose weight, but it will not be a direct cause of your weight loss. The vitamin-enriched powder can, when mixed with milk, provide you with a good portion of your daily recommended amounts of vitamins A, B6, B12 and C, as well as zinc, calcium and magnesium. However, there are lower-calorie ways to get those nutrients. You would need to drink nearly 1,000 calories worth of Ovaltine per day to get your vitamins, and this would leave virtually no caloric room in your diet for foods that supply essential proteins and fats.
Multiply your weight by 10 if you are an inactive woman, by 13 if you are an inactive man, by 12 if you are a moderately active woman, and by 15 if you are a moderately active man. The result is a good estimate of the number of calories your body burns on a daily basis. If you are trying to lose weight, you should never consume more than this number of calories in a day.
Design your daily meals so that their caloric total, including Ovaltine, is less than the result from Step 1. That way, your body will burn more daily calories than you consume and you will begin to lose weight. According to the President's Council on Fitness, Sport and Nutrition, however, you should eat a minimum of 1,200 calories per day.
Drink Ovaltine with each meal or as a dessert after healthy meals. Do not consume more than half your daily calories from Ovaltine. You should view Ovaltine only as a tasty vitamin supplement for meals including whole grains, fruits and vegetables, nuts, peas, beans and lean meats and poultry.
Exercise each day to burn extra calories and accelerate your weight loss.
