Can I Lose 7 Pounds In 7 Days?
So, how many pounds can I lose in a week?
We all want to lose weight quickly, but according to the Centers for Disease Control and Prevention (CDC), you should only aim to lose 1 to 2 pounds of fat per week for healthy, sustainable weight loss.
However, this refers to true fat loss, which requires creating a caloric deficit.
This means you are burning more calories per day than you are eating.
You will lose 1 pound of body fat for every 3500 calories that you burn above what you are consuming; therefore, to lose one to 2 pounds per week means that you are creating a daily caloric deficit of 500 to 1000 calories.Losing 7 pounds in 7 days is, therefore, unreasonable because it would necessitate burning 3500 cal per day above your caloric needs.
However, there is an important caveat: this refers to 7 pounds of fat loss, not overall weight loss.

You can easily drop a significant amount of water weight if you’ve been generally following an unhealthy diet, consume a lot of carbs and processed foods, regularly drink alcohol, have a lot of chronic inflammation or hormonal imbalances, and eat salty foods regularly.
In these cases, your body may be storing a lot of water weight that you can shed quickly if you want to lose 7 pounds in 7 days and are less concerned about true fat loss and are mostly interested in overall weight loss.
According to the Academy of Nutrition and Dietetics, an endurance-trained athlete can store up to 1,800 to 2,000 calories of fuel as glycogen in the muscles and liver, or about 500 grams.
Because the body stores about 3 to 4 grams of water for every gram of glycogen, if you go on a low-carb diet in your 7 pounds in 7 day weight loss plan, you can deplete this glycogen and lose the water weight along with it.
If you have 500g of glycogen in your body stores, just 3 g of water for each of these, you have 2000 g of glycogen and water.
This is a total of 4.4 pounds.
Therefore, if you lose 2 pounds of true fat and the 4.4 pounds of water weight with your glycogen, decrease your sodium, and remove alcohol, you can probably lose 7 pounds in a week, but most of it will be water weight.

What Is the Best 7 Day Weight Loss Meal Plan?
There isn’t a best 7 day weight loss meal plan or 7 day meal prep for weight loss that will necessarily meet the dietary needs, food preferences, and budget for everyone.
We all have different caloric needs, and if you want to follow an ongoing, healthy, sustainable weight loss meal plan, you should only aim to create a 500 to 1000-calorie deficit every day.
This is between your weight loss diet and exercise program relative to your total daily energy expenditure.
However, we have created a 7 day weight loss meal plan that is intended to jumpstart weight loss by helping shed extra water weight and reset your pallet, steering away from high-sugar, high-sodium, fatty, processed foods so that you can make healthier weight loss diet choices moving forward.
This 7 day meal plan for weight loss is not intended to be a long-term diet as it provides too few calories for almost all adults, according to the USDA.
Many people fall off programs where they try to lose weight in a week, so one of the best tips for how to lose weight at home in 7 days is to remove some of the common barriers and obstacles of following a “lose weight in 7 days challenge.“
One of the best tips for how to lose weight in a week is to do a 7 day meal prep for weight loss so that you do not have to keep making every individual meal or think about what you are going to eat.
Preparing weight loss meals in advance will help reduce the time and energy you have to spend cooking meals for weight loss and can cut back on impulse purchases or bad food decisions when you haven’t thought out what you will eat.
Therefore, we have streamlined this 7 day weight loss meal plan to include the same meals every day so that you can do some weight loss meal prep in advance.

You will follow this low-carb 7 day meal plan for weight loss each day of the plan. You can meal prep most things in advance.
For example, meal prep the lunch and dinner salad by chopping the veggies and preparing the salads in mason jars.
For the lunch salad, pre-cook your lean protein by baking and slicing chicken breast or turkey breast, or dicing and steaming tofu. Rinse and drain your chickpeas for the dinner salad and assemble the salads in the mason jars without adding the dressing.
Pre-mix the dressing and put it in little to-go containers, or leave it in your refrigerator and serve it over the salad right before you eat it.
The breakfast scramble requires very little meal prep.
Simply crack one whole egg and then use either liquid egg whites measured out or separate four eggs and use the egg whites. Chop your tomato and wilt your baby spinach.
The cottage cheese simply requires tossing in the fresh berries.

You can do some 7 day weight loss meal prep on the tuna salad. Chop up 14 celery sticks and rinse and drain tuna packed in water. Combine with Dijon mustard and seasonings such as pepper, cumin, or paprika.
The dessert protein shake does not require any preparation and should help you feel satisfied both emotionally with the sweet taste of chocolate, and the 25 g of protein before bed will help you stay full overnight.
Additionally, liquids are filling because they are heavy in your stomach, helping you feel full.
Because there are no carbs or very few carbs in the bedtime snack on this 7 day meal plan, you won’t experience sugar crashes or an insulin spike before bed.
Overall, this is a low-calorie, high-protein 7 day weight loss diet plan.
Again, it is NOT intended for long-term adherence; it is likely to be low in total calories for most adults, according to the 2020-2025 United States Dietary Guidelines, depending on your current body weight and activity level.

Remember, to lose 2 pounds per week, which is the upper-end range of what is recommended for the amount of weekly weight loss that is healthy and sustainable, you should create a caloric deficit of 1000 calories per day.
This does not need to be generated entirely through a low-calorie weight loss diet plan; you can also increase your physical activity to burn more calories. Therefore, alongside this 7 day weight loss meal plan, you should exercise every day.
Here is the suggested 7 day workout program for weight loss to accompany the 7 day weight loss meal plan:
- Monday: At least 8000 steps and 30 to 60 minutes of moderate-intensity cardio exercise
- Tuesday: At least 7000 steps and 20 to 30 minutes of vigorous-intensity cardio exercise
- Wednesday: At least 10000 steps, full-body strength training, and stretching
- Thursday: At least 8000 steps and 60 minutes of moderate-intensity cardio exercise
- Friday: At least 7000 steps and 20 to 30 minutes of vigorous-intensity cardio exercise
- Saturday: At least 10,000 steps, full-body strength training, and stretching
- Sunday: At least 7,000 steps, 30 minutes of moderate-intensity cardio, plus do the 7 day meal prep for weight loss diet plan moving forward

Note that this is a very aggressive and intensive exercise program that exceeds the minimum recommendations for physical activity for adults for weight loss.
However, this weight loss exercise plan is designed to be part of a kickstart weight loss challenge.
Above all, you need to listen to your body.
If you have been physically inactive up until this point, just start from where you are. Begin increasing your step count every day and trying to reach at least 7000 steps per day. Then, try to layer on additional cardio and resistance training workouts.
