4-Week Shred Diet: Get Your Six-Pack By Switching Up Your Diet

4 week shred diet female

How quickly can you get a six-pack? Remember, getting a six-pack is not only about building muscle – it’s about burning fat as well. You could be very fit, but without the right routine, your six-pack won’t show. Burning fat starts with a proper diet. Additionally, intense exercise goes a long way to boost your efforts. So, for the 4-week shred plan diet and workout, you’ll have to do a little more than be on a calorie deficit and hit the gym every three days.


Here’s how to lose weight and gain muscle in 4 weeks.  

Step 1: Switch Up Your Workouts

Probably the most important thing you can do for a more toned body is to increase your lean mass. Burning fat is crucial, but the more muscle you have underneath, the more ripped you’ll look. Plus, muscle burns fat and increases your metabolism (7).

Strength Train To Build Muscle

As we said, the number on the scale doesn’t matter – it’s all about how much fat your body has stored. Thus, to burn more fat, you need to build muscle mass and strive for a higher metabolism. 

Lifting weights is one of the best ways to do this. You don’t have to do it every day, but we suggest you make a point of hitting the gym for a strength training session at least thrice a week for the next four weeks (5). 

As for how many sets and reps to do each session? Just follow this simple rule: 3 x 8. It means that you should lift weights three times (sets) per exercise and do eight reps (or more) on each set. The last set is always an “all-out” one where you try to hit as many reps as you can. 

What kind of training regime should you follow? A program based more on compound exercises, those that work for multiple muscle groups at once, and less focus on targeted ones such as biceps curls and triceps extensions that will help maximize results.

Compound exercises for abs include: 

  • Deadlifts, where you lift weights by bending over and grabbing them with both hands; 
  • Squats, which train your quadriceps but also activate the muscles in your abdomen, back, and glutes; and
  • Push-ups, which train your chest, shoulders, and triceps, and core.

Add High-Intensity Interval Training

Forget running on the treadmill for hours; high-intensity interval training is known to be  a more effective way to get shredded fast (6). HIIT involves short, burst-like exercises followed by a period of rest. Studies have found that adding this type of training to an exercise may help burn fat even after working out.

To get shredded, do HIIT training at least three times a week for 20 minutes with as little rest in between sets as possible (30 seconds to 1 minute) (6). High-intensity interval training can be performed on any piece of cardio equipment, but the treadmill and rowing machine are particularly effective. 

Be sure to mix up your routine by trying different exercises that work for large muscle groups all at once. It will help increase your lean muscle mass while getting rid of your body fat at the same time.

Step 2: Switch Up Your Diet

Everyone knows how to diet. Cutting calories consistently is the most effective way to lose body fat. However, if you have less fat to lose and more muscle to build, cutting calories too low or choosing the wrong macros can compromise your lean muscle mass (9). 

Here’s how to switch up your diet:

Eat Enough Protein

According to the Dietary Reference Intake report for macronutrients, a sedentary adult should consume 0.8 grams of protein per kilogram of body weight or 0.36 grams per pound. That means that the average sedentary man should eat about 56 grams of protein per day, and the average woman should eat about 46 grams (3).

This is a good starting point, but research shows that exceeding these recommended amounts can help boost muscle mass gains in the gym as well as fat loss outside of it. While you are strength training, aim for between 1 and 1.5 grams per kilogram of body weight per day (3).

Moreover, high protein diets (at least 25% to 30% of your calories from protein) can support better appetite control and reduce cravings (1).

If you have trouble getting that much protein from food due to dietary restrictions or preferences, then you may find a high-quality protein supplement helpful. Both plant- and dairy-based protein supplements are commonly available.

Eat A Moderate Amount Of Healthy Fats

Getting too many calories from saturated fats and trans fats could cause damage to your arteries, increase inflammation in the body and worsen insulin resistance – all of which will affect your health and could hold back your gains in the gym. However, healthy fats, such as the ones found in foods like avocados, olive oil, and fatty fish, can be appetizing and satisfying since fat provides appealing flavor and mouthfeel to foods, making it easier to stick to your diet (12).

At least one study has shown that people who get a moderate to a high percentage of their daily calories from fat experience a reduction in body weight and abdominal fat after 6 months of being on a high-fat, low carbohydrate diet (2). So make sure you’re getting enough healthy fat every day to lose weight.

Try Carb Cycling

If you’re looking at getting a six-pack, then you need to know about one of the most effective ways to get there: carb cycling. This is when your carbohydrate intake varies from high to low for a week or more, with higher and lower intakes on different days (4). 

Doing this is thought to help keep insulin levels in check and the body primed for muscle growth (8). The key to getting shredded through carb cycling is synchronizing your high-carb days with intense exercise days. This way, you have enough energy for intense workouts without increasing your overall calorie intake.

Step 3: Get Some Sleep, And Less Stress

Stress can hinder your muscle gains. It can cause the body to release cortisol, which is a hormone that can increase belly fat and put the body into a “fight-or-flight” mode (11). If you’re feeling stressed out, then it’s recommended that you try meditation. Meditation has been shown to reduce stress levels while boosting your energy at the same time. Other forms of self-care can also be effective, so do whatever works for you.

Sleep helps increase recovery time while promoting muscle growth at the same time (10). If we don’t get enough sleep, our cortisol levels will stay high (making us more prone to storing fat), and if we have too much, then testosterone will be suppressed. As such, aim for between seven and nine hours of good quality sleep every night; this should help with shredding off unwanted body fat while building lean muscle fast. 

The 4-Week Shred Diet Plan

Looking to build muscle in four weeks? Here’s a sample week-long meal plan you can use. 

It contains approximately 1500 calories a day, including a healthy amount of carbs and protein to fuel your muscles and support your training, and a relatively low-fat content (10–15% of total daily calories). This calorie level isn’t enough for everyone, so make sure to adjust for your individual needs.
