Created in 2003 by cardiologist Arthur Agatston, this low-carb diet features three phases. The first phase is the most restrictive, limiting carbs such as potatoes and rice. Each subsequent phase becomes more lenient, and the diet emphasizes lean protein, unsaturated fats, and low-glycemic carbs such as nonstarchy vegetables. South Beach promotes lasting lifestyle changes, according to the Mayo Clinic. (21)

Some men can lose up to 5 lbs. per week, says Juge, if they follow the diet strictly. He recommends striving for a weekly 2- to 3-lb. loss for more lasting effects. "That way it's not such a drastic change and you'll be less likely to put all the weight back on when the diet's done," he adds. Weigh yourself naked just once per week, at the same time, preferably on the same scale. That way it'll be as accurate as possible.
On the Lose Weight by Eating Diet Plan, we recommend you try to drink a gallon of water (3 ¾ liters) a day for weight loss. A gallon of water may seem like a lot, but it’s a good weight loss goal to strive for each day. By having 40 ounces of water in the morning, noon and night you will stay full and hydrated. The large amount of water helps increase your metabolism and flush your system, it’s a great aid to weight loss and an easy step that almost anyone can achieve. (1)
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.

Many commercial weight-loss plans assign women to a 1,200 calorie per day diet plan. The number might be higher, however, if the woman is physically active. For example, you might see that your weight loss calorie goal is 1,200 calories per day. But if you choose to burn an extra 300 calories per day through exercise, you can eat 1,500 calories and still lose weight.


So as tedious as this one step might seem,  it is an important step for both weight loss and maintenance later on and it holds everything together. Having a meal plan helps you manage plateaus while keeping you motivated. In the long run you’ve studied for your new healthy lifestyle and for your new figure. It makes it easier to maintain your weight loss diet when you have done the studying. So don’t skip this step, you’re studying for the most important test of your life… your health.
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
Habits and cravings are the devil when it comes to dieting. Let's first deal with habits. Juge explains that it takes a good week or two to ease into dieting. "Fast food is so easy and there's a McDonald's on every corner. The hardest thing is to develop the new habit of preparing your meals and taking them with you." The first week is the most difficult, so prepare yourself for some challenges as you abandon your usual routine. For example, you might usually go out for a sub sandwich or burger at lunch. You'll now have to bring your food with you and resist the temptation of spicing up your meal with the Doritos in the vending machine or your usual can of Coke. It can be a real mental battle to stick to your food plan.
Opt for smaller bowls instead of large dinner plates, suggests Rachel Goldman, PhD, FTOS, a senior bariatric psychologist at the Bellevue Center for Obesity & Weight Management. Similarly, a study in the journal Appetite found that people ate more candy when the bowl of sweets was closer to their desk. Try plating dinner away from the table instead of serving family-style to combat overeating or mindless grazing. Don’t miss these tips for getting over a weight loss plateau. 

To lose weight, you need to burn more calories than you consume. One pound equals 3,500 calories. If you cut 500 a day from your diet, you will lose a pound a week. People who lose weight slowly, about 1 to 2 pounds per week, are more successful at keeping the weight off. You also will burn additional calories if you increase your physical activity.

“There are many diet plans on the market today that promote good health,” says Emily Kyle, RDN, who is in private practice in Rochester, New York. “The key is finding one that does not cause you stress or agony.” Ask yourself questions such as: Would the diet guidelines make you happy? Anxious? Stressed? Are you able to follow them long term? “Factors such as enjoyment, flexibility, and longevity should be strongly considered,” adds Kyle.
Who says you shouldn’t eat less than 1800 kcals? Under normal circumstances, the minimum is 1200 for women, 1500 for men, and height and weight have no bearing – these are what the body requires to avoid starvation. This diet is, however, for 7 days only, it is not intended as a long-term weight-loss strategy, so 6 days at less than 1500 won’t do you any harm. You don’t say how tall you are, or what you do for a living, which would also have a bearing on your long-term weight-loss plans. Good luck with it, anyway – it’s not easy
