I have found that one of the best ways to lose weight is by cutting carbs. So one of the questions I had when considering Medifast to lose weight was whether or not Medifast was a low carb diet. While Medifast is probably best known for being a low calorie meal replacement plan, it turns out that it is low carb too.
Since Medifast has so many food choices now, how many carbohydrates you consume each day depends a lot on the food choices that you make. Also, whether or not you have the additional snack allowed will make a difference too. For the most part, the Medifast plan will keep your carbohydrate consumption somewhere between 65g and 100g per day. This isn't quite as low as the Atkins induction period, which keeps your carbs to less than 20g per day. However, it is a significant enough reduction to put your body into a very mild state of ketosis each day to help with fat burning.
Ketosis is the reason low carb diets allow you to lose weight so quickly. Basically, ketosis is what happens when your body starts burning fat for energy rather than carbohydrates. When you dramatically cut the carbs in your diet, it will take a few days for your body to make the switch so it's important to persevere with your diet plan during the first three to four days. Once your body starts burning fat, however, you should notice very quickly that a lot of your hunger and cravings have disappeared and you may even feel a bit more energy.
It is after these first few days have passed that your weight loss really kicks into gear so once you get through them, you should be rewarded pretty quickly by the numbers on your scale. Unfortunately though, you need to be quite vigilant to maintain this fat-burning state. Increase your carbohydrates too high and you'll get kicked right out of ketosis and require another couple of days to get back in the groove.
Since everyone's body reacts differently to carbohydrates, you may find you need to cut carbs even lower to achieve real success with Medifast. So if you find that the weight is coming off a bit slower than you like (say, less than 2 lbs per week), consider cutting the Medifast bars and sticking to the shakes and other foods. And cut the extra Medifast snacks.That should keep your carbs low enough to keep your weight loss trucking along at a nice pace.
