Phase One of the SouthBeach Diet: The South Beach Diet is a popular 3-phase weight loss program with monthly meal delivery of their prepared low-carb, high protein, portioned foods, and it starts with Phase 1.
The goal of this first, 7-day phase “body reboot” is to reset your body for fast weight loss by breaking unhealthy cravings and bad habits.
By eating their low-carb, high-protein foods, you’ll transform your metabolism and switch from burning carbs to fat as fuel. This should encourage fast initial weight loss, and also help to prepare your body for sustained weight loss in Phase 2.
Here’s what you need to know about Phase One of the South Beach Diet:
How Phase 1 Works:
“Let’s start at the very beginning, a very good place to start” – Do-Re-Mi, The Sound of Music
There are 3 phases in the South Beach Diet, and it all starts with the all-important Phase 1, aka “The 7-Day Reboot.”
Phase 1 is the foundation of the South Beach Diet, and it does three important things:
- Resets your body
- Reduces your cravings
- Prepares you for a period of gradual and sustainable weight loss
Normally your body burns carbs as its primary fuel source. When you’re on a lower-carb diet, like South Beach, your body turns to it’s second option, which is fat. When you burn fat, you lose weight. Simple, right?
Here’s a nifty infographic showing how cutting carbs and eating more protein helps you lose weight:
Healthy food is the foundation of the South Beach Diet, so let’s look at the Phase 1 meal plan.
Phase 1 Meal Plan:
Phase 1 is the most restrictive phase of the South Beach Diet. Their specially selected menu of lower-carb foods for Phase 1 helps to reset your body and curb unhealthy cravings.
During Phase 1 you’ll avoid all: refined carbs, grains, fruits, beans and legumes, sugary drinks, and alcohol. You’ll also limit dairy and diet soda.
South Beach Diet® provides you most of your food for Phase 1 including 5 days of meals, plus bars and shakes. However, you’ll also need to add 2 days of DIY meals of your own healthy choices from their recipes or the Phase 1 food list below. So, what do you eat during Phase One?
Each day during Phase 1 you’ll eat:
- Women: 3 lean proteins, 2 healthy fats, 5 non-starchy vegetables
- Men: 3 lean proteins, 3 healthy fats, 5 non-starchy vegetables

• Foods to Avoid in Phase 1:
Phase 1 is the strictest part of the South Beach Diet, but it only lasts 7 days!
So, why do they ask you to avoid certain foods? Eating too many sugary and processed carbs has thrown your metabolism and blood sugar out of balance, and the goal of Phase 1 is to fix that.
You could call Phase 1 a “body reboot.” By avoiding certain foods, Phase 1 helps get your body and glycemic index back on track.
In Phase 1 you should avoid these foods:
- Refined carbohydrates (no doughnuts, white bread, or mac and cheese!)
- Grains, fruits, and beans/legumes
- Sugary drinks and soda (limit “diet” sodas)
- Alcohol including wine and beer (sorry!)
Here are some popular foods not allowed during Phase 1:
- Beef: No fatty cuts of meat like brisket, prime rib or veal!
- Poultry: Avoid chicken wings & legs, and duck
- Pork: No honey-baked ham!
- Starchy vegetables like: potatoes, green peas, beets, corn, and yams
- Fruit: Skip the fruits in Phase 1. No apples, berries, peaches, pears, cantaloupe, etc.
- Starches & Carbs: No pasta, rice, bread, cereal, oatmeal, or baked good!
- Drinks: Avoid fruit juices, juice cocktails, sodas, and limit diet drinks
Tip: So, can you eat hummus? You can not eat hummus in Phase 1, as chick peas are a legume. After Phase 1 you can eat hummus (2 oz portion), but skip the pita bread and try it with veggies like carrot sticks, sliced cucumbers, and broccoli instead.
• Phase 1 Sample Menu:
So, what do meals actually look like? Here’s a sample South Beach Diet Phase 1 menu including breakfast, lunch, dinner, and snacks:
- Breakfast: (7 am) South Beach Diet® Farmhouse Garden & Cheese Omelet + Greek yogurt
- Morning Snack: (10am) South Beach Diet® Dark Chocolate Nut Bar
- Lunch: (12:30pm) South Beach Diet® Mushroom Parmesan Soup w/ Chicken
- Afternoon Snack: (4pm) Hardboiled egg and cucumber slices
- Dinner: (7pm) South Beach Diet® Broccoli and Cheese-stuffed chicken breast with a small kale salad
*You’ll also drink at least 64 oz. of water per day. View more menu items
Tip: The variety of food increases after the week-long Phase 1 ends, and then you’ll have a lot more menu options for your meal plans!
• Phase 1 Exercise:
Do you have to exercise during Phase 1? Yes. Healthy eating isn’t enough for any weight loss program, as exercise is a key component. That’s why the SouthBeach Diet asks you to be active and move your body for at least 30 minutes a day.
Get that heart rate up!
This “exercise” could be anything from taking a brisk walk or riding your bike, to a yoga or Zumba class, or swimming.
Tip: Walking your dog at the same time every day is a great way to get exercise and reduce stress. Plus, your brain loves routines!
Tip: Learn “Mindful Eating”
Do you ever eat at your desk or while driving? Yikes, that’s not good!
Neither is eating too fast, as it causes you to each too much. Phase 1 encourages you to be aware of food, and slow down your eating. Put your phone away, relax and enjoy each bite.
- Think about the texture and flavor of what you’re eating
- Put your fork down between bites of food
- Hungry after a meal? Wait 20 minutes to eat anything else, as that’s how long it takes for your body to know it’s full!
Stress is a major reason why people eat too fast and make bad choices. During Phase 1 the goal is to eat mindfully and end your bad eating habits.
Phase 1 Weight Loss Results?
During Phase 1 of the South Beach Diet, the company claims that you can lose up to 7 pounds in 7 days during Phase 1.
In an independent study, the average weight loss result during the 7 days of Phase 1 was 5.8 pounds, which is pretty consistent with South Beach Diet’s claims.
After Phase 1, you can expect to lose a sustainable 1-2 pounds per week until you reach your weight loss goal.
Tip: Users are encouraged to always eat everything in their monthly deliveries, as skipping meals does not help with sustainable weight loss.
Phase 1 of the South Beach diet can be considered a body reboot. It’s 7 days (which used to be 14) of relatively strict rules to clean out the junk in your system and ending your bad eating habits.
It’s a way of letting your body know that, “the times, they are a changing” and the days of unhealthy eating and carb cravings are over. Instead, you’ll be eating foods lower in carbs, and high in protein and fiber to encourage weight loss and better health.
As you can guess, Phase 1 is followed by Phase 2, which is the long-term weight loss phase lasting until you reach your goal weight.
