7-Day Weight Loss Low-Carb Diet: Choose High-Protein, High-Fiber, or Ultra-Low-Carb

The idea that a 7-day weight loss low-carb diet can help you lose weight is fantastic. Who wouldn’t want to shed some pounds in only a week? However, is it possible? What’s the safest low-carb method for losing weight over seven days? Could you go longer than that?

Our 7-day weight loss low-carb diet is only the tip of the iceberg. We’ll give you options for different low-carb diets, discuss how to prolong your journey, and ideas on how much weight you may lose. Let’s start with the burning question! How can you lose up to 4.4 pounds in a week?

How to Lose 2 KG in a Week Meal Plan

We have three 7-day weight loss low-carb diets to help you lose the most weight in a week, and other plans that last longer. However, you shouldn’t expect to lose 2 kg in a week. A more realistic goal would be around 1-2 pounds, or about 0.5-1 kg of weight lost per week. This will happen over the course of your weight loss journey, and won’t necessarily be linear. Each plan contains nutritionally dense low-carb foods (21, 11, 4). Here’s a sneak peek:

  • 7-Day Protein Diet for Weight Loss
  • 2-Week Low-Carb 1,200-Calorie Meal Plan
  • 30-Day Low-Carb, High-Fiber Diet for Weight Loss

But first, let’s understand what healthy weight loss means and how low-carb diets potentially work.

Low-Carb Meal Plans 101

A simple low-carb meal plan may help you shed a few pounds. Still, it’s good to know the basics before diving head-first into any diet plan.

What Is a Low-Carb Diet?

Our 7-day weight-loss low-carb diet focuses on nutrients to replace a lack of fiber found in some low-carb diets. Some carbs contain fiber, which is essential in a balanced diet. UCSF Health recommends 25-30 grams of fiber daily (8). Not all low-carb diets meet 30 grams.  

However, low-carb diets vary. Keto is a famous very low-carb diet that encourages you to eat high-fat, lean protein, and low-carb foods, limiting daily carbs to under 50 grams (9). Meanwhile, the Atkins Diet is a high-protein plan that gradually lets you increase your daily calorie carbs up to 100 grams (7). 

Still, the National Library of Medicine says a low-carb diet will mean you eat under 26% of your daily calories from carbohydrates, or under 130 grams of carbs per day on a 2,000-calorie plan (14). In some ways, all low-carb diets have a few things in common. 

Weight-Friendly Low-Carb Foods

Some low-carb foods include various nutrients and sources (21, 11, 4):

  • Lean protein: Chicken breast, beef, no-crumb pork chops, lamb, and eggs.
  • Seafood: Shrimp, tuna, salmon, trout, and haddock.
  • Non-starchy vegetables: Leafy green vegetables, cauliflower, asparagus, broccoli, cabbage, Brussels sprouts, zucchini, cucumber, and tomatoes.
  • Low-carb fruit: Raspberries, strawberries, blueberries, blackberries, cantaloupe, avocados, apples, and oranges.
  • Nuts or seeds: Nut butter, almonds, walnuts, pistachios, cashews, flaxseeds, sunflower seeds, and chia seeds.
  • Healthy fat: avocados, olive oil, avocado oil, and canola oil.
  • Unsweetened dairy: Plain yogurt, Greek yogurt, cottage cheese, etc..


What to Moderate on Low-Carb Diets

Some foods contain higher carbs, but you can eat them in moderation (11, 4):

  • Higher-carb fruits: Bananas, mangos, pineapples, and grapes.
  • Legumes: Black beans, pinto beans, chickpeas, and lentils.
  • Starchy vegetables: Potatoes, sweet potatoes, peas, and corn.
  • Whole grains: Quinoa, bulgar, brown rice, and oats.

What to Avoid on Low-Carb Diets

Some foods contain too many carbs to add to low-carb plans (11, 4):

  • Processed snacks: Cookies, chips, pretzels, cakes, ice cream, candy, and crackers.
  • Refined grains: White bread, white rice, flour tortillas, and flour-based pasta.
  • Diet products: Low-fat or diet products, which often have a lot of refined carbs or added sugar.
  • Sugary beverages: Soda, fruit juice, sweet tea, and energy drinks.

Will I Lose Weight if I Eat No Carbs for a Week?

WebMD says you’ll likely lose weight when suddenly cutting carbs because glycogen stores will decline, making you lose water weight (20). However, reaching ketosis is said to take 2-3 weeks. This means that you may regain the weight quickly if you only lose water weight. 

Low-Carb Caution for Diabetics!

A study from the Czech Republic found that diabetic type 1 children could have positive and negative effects on a low-carb diet (13). The children showed modestly improved blood glucose regulation. However, they tended to have more frequent hypoglycemia, which can be dangerous. Please consult a doctor before going low-carb if you’re diabetic.

Can You Lose 10 Pounds in a Week on Low-Carb?

The first week of a low-carb diet combined with aerobic exercise may help you lose ten pounds in a week. Spanish researchers found that every gram of glycogen in your muscles holds three grams of water (17). Meanwhile, WebMD says glycogen stores decline sharply when you lower or cut carbohydrates (20). Prolonged exercise can also deplete glycogen stores.

Depending on how much glycogen you have stored and how quickly you deplete it, you could lose a significant amount of weight in a short amount of time, but this will be mostly water which will come back when your glycogen stores are replenished. This rapid weight loss is not a goal to aim for, as it is not sustainable and it isn’t fat loss. 

How Much Weight Can You Lose in 7 Days on the Low-Carb Diet?

After the initial burst of weight loss in the first week, you should aim for the recommended weight loss weekly. The National Lung, Heart, and Blood Institute recommends losing 1-2 pounds weekly (10). You need a 500-750-calorie deficit to achieve this rate of weight loss. 

3 Low-Carb Meal Plans to Suit Everyone

A low-carb diet plan for weight loss can go for 7, 14, or even 30 days. You’ll discover three different low-carb diet plans, lasting different periods. Choose the one that suits your goals, but speak to your healthcare provider first if you have any medical conditions or are taking any medications. A low-carb diet is not suitable for pregnant or breastfeeding women.

30-Day Low-Carb Meal Plan

The final 7-day weight loss low-carb diet plan works on repeat until you finish 30 days. However, we changed up the game to suit someone who wants to eat less than 1,600 calories daily.

  • How to Lose 10 Pounds in a Week?

It is highly unlikely that you will lose 10 pounds of fat in a week, but some people might lose that much water weight in a short amount of time. The first week of a low-carb diet combined with 150 minutes of vigorous aerobic exercise in a humid environment may help you lose several pounds of water weight in a week. 

Spanish researchers say every gram of muscle glycogen holds three grams of water (17). WebMD suggests glycogen stores decline fast when you suddenly lower or cut carbs (20). However, that weight is mostly water and will return once you replenish your glycogen stores.

  • Can I Do Low-Carb 5 Days a Week?

Some people use the cyclical ketogenic diet (CKD) to eat low-carb for five days a week and high-carb for the remaining days when they want to exercise vigorously. Research from the Czech Republic found that CKD helped men lose weight with exercise similar to a nutritionally balanced reduction diet, however, the CKD diet had a neutral effect on muscle strength and endurance and slightly reduced muscle mass (18). 

  • What Is the 30-30-30 Rule for Weight Loss?

The rule is that you eat 30 grams of protein 30 minutes after waking, followed by a 30-minute low-intensity workout. The Mayo Clinic says the 30-30-30 rule is another FitTok trend (22). Eating 30 grams of protein for breakfast may keep you full longer, and the trend may encourage you to eat a nutritious breakfast in the morning.

  • Has Anyone Lost Weight Walking 10,000 Steps a Day?

Walking is a low-impact exercise that may help you lose weight, especially if you control your calories. Colorado scientists found that walking 10,000 steps a day with a calorie-restricted diet helped individuals lose weight in their study (16). 3,500 of the daily steps were performed as bouts of moderate to vigorous physical activity.

The Bottom Line

Our 7-day weight loss low-carb diet plans give you options. Choose the high-protein diet if you exercise, or go for the lower keto-style plan to lose weight fast. Alternatively, pace yourself with the high-fiber 30-day diet plan to stay satisfied longer.
