How to define the body

To know how to define muscle, you must take into consideration two basic factors: genetics and your daily habits. While many gain weight easily, many others find it very difficult. For this reason, you must make sure, first of all, that you eat properly according to the characteristics of your metabolism. If you consider it necessary, consult a nutritionist to create a food plan adapted to your body.

In this way, it will be easier to reach your ideal weight, with a percentage of body fat close to 10%, which is recommended by professional trainers.

Regardless of your genetics, if you’re wondering how to define your body, habits are the key. The diet, the hours of rest, the type of training and the perseverance play a fundamental role in getting the muscles to achieve the toning you want. It’s not always easy, but you’ll start to see results.

Next, we explain what foods to consume and the best routine to define muscles and burn fat. Thus, you will be able to make the most of your time at home and in the gym, so that your work routine does not affect your physical condition or your figure.

Diet to define muscles

diet to define is always rich in foods with a high content of proteins and carbohydrates. To design a proper diet you must first consider your current weight and the weight you want to achieve. Then, your tastes also count, because the idea is that you enjoy your meals without restrictions that are impossible to maintain.

The most important thing in a diet to define muscles is the distribution of food. It is advisable to eat balanced portions in basic meals (breakfast, lunch and dinner), without neglecting mid-morning and afternoon snacks, since these may coincide with your hours of physical exercise.

Next, we show you a table with the best foods to define your body, as well as the best time to consume them:


To start the day it is necessary to eat foods rich in carbohydrates, as well as healthy fats. Whole-grain bread, oatmeal, milk, cheese, eggs, and whole-grain cereals are the best choices for the most important meal of the day.

With these foods, you can prepare breakfasts such as whole-grain toast with eggs, oatmeal or corn gruel, as well as eggs with bacon, ham and cheese sandwiches with orange juice, or a cup of whole-grain cereal with milk. This way you will have enough alternatives for the whole week.


At about 10 in the morning, it is advisable to have a good fruit smoothie. Protein shakes are your best option. You can try options like a low-fat yogurt shake with banana and egg white, an oatmeal shake with wheat germ and soy protein, or a chocolate shake with almonds.

At lunch, foods rich in protein should be the protagonists of your diet to define muscles. Lean meats contain less saturated fat and up to 36% protein intake. Similarly, fish (mainly tuna and salmon) can provide you with about 30 g of protein per 100 g.

Shellfish are also an excellent source of protein, as are chicken and turkey breasts, and soybeans. You can alternate these foods with rice and pasta, as well as with soups and chicken and fish consommé. Grains such as lentils and chickpeas should not be missing either, incorporate them at least once a week to your lunches.

Afternoon snack

In mid-afternoon snacks you can eat fruit pieces (apple, pear, banana, peach), yogurt and dried fruit (rich in protein). You can also alternate with some snacks (a handful of almonds or peanuts will be enough) and natural fruit juices.


To end the day you can end with something light, rich in fiber and protein. A chicken breast with tuna salad or a cup of whole grain cereal with milk will always be a good option for a healthy dinner. You can also try some oily fish and shellfish with rice, or a chicken consommé. Some baked potatoes (boiled or cooked) with turkey breast and vegetables can be another fantastic option.
