The amount of carbs one consumes in a day with the intent to lose weight will vary from person to person depending on his height, weight, level of activity and age since the metabolism changes over the years. Low carb diets are a great way to control your intake of calories but it is important that you do not starve yourself or else the body will move into a defensive state and you will feel lethargic and weak.
Good Carbs vs Bad Carbs
The carbs that you get from artificially sweetened juices are not the same as the carbohydrates that you get from fresh juices. You should look to change your lifestyle instead of changing your diet for a few weeks before going back to the same processed foods. Processed wheat and products containing added sugars are your absolute enemies. Try replacing them with fruits and dark chocolate to prevent your energy levels from dropping while ensuring a positive change.
Bring in the proteins
Protein is a denser macronutrient as compared to carbohydrates and it your daily caloric requirements should be fulfilled with protein once you reduce the carbs that you are consuming. This will have two benefits as not only will it help your muscle structure to grow but will also keep your stomach full since it takes longer to get digested. Your appetite will then stay under check and you will not be consuming calories through pointless snacks.
How many carbs are enough?
On average 130 grams of carbohydrates are enough based on the one carbohydrate per pound equation but since the point is to let the metabolism rate benefit the weight loss procedure, the amount of carbs can be equated to 1 carbohydrate per kilogram. This would be optimum for the body to lose weight and for stabilized energy levels.
However in case you are looking for quicker results, people have been known to consume 20-40 grams of carbohydrates per day to really make sure that the metabolism starts burning up the fats stored in the body. This may give you quicker results but it is not a healthy choice in the long run as you could harm yourself. There are various calculators online that will base your carbohydrates requirement depending on your weight, height, activity level and weight goals. Try to choose a mix that is not too strenuous on the body and always remember weight loss is a lifestyle change not a one day challenge.
