One of methods that have been used a lot for preventing weight gain is meal replacement. It is safe, efficient, cost-effective, and without any side effects.[3,15] In this method the level of compliance is better, the receipt of nutrient intake is sufficient, and the drop-out rate is low.[15,16] The calorie density of these meals is controlled and they are also nutrient-dense. Main meals and snacks can be replaced by these nutritionally balanced low-fat meals. Table 1 shows the meal replacement trials for weight maintenance.
If you're still feeling confused about how to manage your portions and how much of which types of food you should eat, a nutritionist can help. A nutritionist will give you information specific to your body and your dietary needs. Nutritionists are also great for telling you what foods you should absolutely cut out all together and where you might have room to cheat a little for favorites once in a while. They can also direct you on moderation. Dark chocolate and red wine, for example, have health benefits when consumed in moderation, even though chocolate and alcohol in general aren't very conducive to dieting. If you spike your blood sugar then when it crashes you will once again be hungry quickly. This is one of the reasons many nutritionists recommend low glycemic index diets with limited carbohydrate consumption.
Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, “people who try to stop eating after 7pm can’t do it every day for the rest of their lives,” says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.
