If you’re trying to get in better shape, it’s natural to wonder what you should be eating.

Should you cut carbohydrates? Eat more protein? Stop eating after a certain time? Give up your favorite foods? Start drinking protein shakes?

With so much conflicting advice online, getting healthier can seem much more complicated than it needs to be.

For most people, progress starts with consistently eating enough protein, choosing nutrient-dense foods most of the time, eating enough carbohydrates to support activity, managing total calorie intake, and building habits that fit real life.


What Does “Eating to Get in Better Shape” Actually Mean?

“Getting in shape” can mean losing body fat, building muscle, becoming stronger, improving cardiovascular fitness, having more energy, improving health, or simply feeling better physically.

  • Lose body fat
  • Build or maintain muscle
  • Improve workout performance
  • Support better recovery
  • Improve body composition
  • Create more daily energy

Your exact needs depend on your goal, body size, activity level, training program, age, and other individual factors. But the nutritional foundation changes less than most people think.

ProteinSupports muscle repair, growth, and maintenance.
CarbohydratesFuel activity and help replenish muscle glycogen.
Dietary fatProvides essential fatty acids and supports normal physiological function.

Research and professional sports-nutrition organizations consistently emphasize adequate energy and macronutrient intake—particularly carbohydrates and protein—for exercise performance and recovery. Review the joint position statement.

1. Start With Protein

If you exercise regularly—particularly if you do resistance or strength training—protein should be one of your biggest nutritional priorities. It provides amino acids your body uses to repair and build muscle tissue.

1.4–2.0grams of protein per kilogram of body weight per day is sufficient for most exercising individuals looking to build or maintain muscle, according to the International Society of Sports Nutrition.

A major systematic review found that the added benefit for resistance-training gains leveled off around an average total intake of approximately 1.6 g/kg/day. Individual needs still vary.

  • Chicken and turkey
  • Fish and seafood
  • Lean beef
  • Eggs and egg whites
  • Greek yogurt or cottage cheese
  • Beans and lentils
  • Tofu and tempeh
  • Whey or plant protein

Protein shakes can be convenient, but they are simply another way to consume protein—not a requirement for getting fit.

2. Don’t Be Afraid of Carbohydrates

Carbohydrates sometimes get blamed for weight gain, but they are not inherently incompatible with fat loss or fitness. Your body stores carbohydrate as glycogen, an important fuel source during moderate- and high-intensity exercise.

  • Rice and potatoes
  • Oatmeal
  • Whole-grain bread or pasta
  • Beans
  • Fruit and vegetables
  • Quinoa and other whole grains

Someone training intensely five or six days per week may benefit from considerably more carbohydrate than someone who is mostly sedentary. The goal is not automatically to eat low-carb; it is to eat an amount appropriate for your goals and activity.

3. Eat More Fruits and Vegetables

One of the simplest ways to improve your diet is also one of the least dramatic: eat more fruits and vegetables. They provide fiber, vitamins, minerals, and bioactive compounds while generally offering relatively few calories for their volume.

VegetablesBroccoli, spinach, peppers, carrots, asparagus, green beans, tomatoes, and leafy greens
FruitsBerries, apples, oranges, bananas, melon, kiwi, peaches, and pineapple

Instead of searching for the perfect “superfood,” focus on variety. You do not need exotic foods or expensive supplements.

4. Include Healthy Sources of Dietary Fat

Dietary fat contributes essential fatty acids, helps absorb fat-soluble vitamins, and serves numerous roles throughout the body. Useful sources include avocado, olive oil, nuts, seeds, natural nut butter, fatty fish, and eggs.

A tablespoon of peanut butter can fit perfectly well into a fat-loss diet. Several unmeasured spoonfuls can add substantially more energy than you realize.

5. If You Want to Lose Body Fat, Calories Still Matter

You can eat nutritious foods and still consume more energy than your body needs. If your primary goal is losing body fat, you will generally need an energy deficit over time.

An overly aggressive diet can make training harder, increase hunger, reduce adherence, and make it more difficult to preserve lean mass.

High protein + resistance training + reasonable calorie control + consistency

A more sustainable fat-loss foundation

The goal is not to eat as little as possible and exercise as much as possible.

6. If You Want to Build Muscle, You Need Enough Food

You can follow a great strength program and consume plenty of protein, but consistently eating too little can make gaining muscle more difficult.

TrainUse progressive resistance training.
FuelConsume sufficient protein and energy.
RecoverAllow sleep and recovery to support adaptation.

This does not mean you need to “dirty bulk.” A moderate increase in food intake may be appropriate depending on your current body composition and goals.

7. Build Most Meals Around a Simple Formula

Nutrition does not need to involve complicated recipes or constant macro calculations. For many people, a simple structure works extremely well.

01Choose proteinChicken, fish, eggs, yogurt, tofu, or beans
02Add carbohydrateRice, potatoes, oats, fruit, or whole grains
03Add produceVegetables or fruit with color and variety
04Include fatFrom the protein or avocado, nuts, seeds, or oil
Grilled chicken bowlChicken + rice + broccoli + olive oil
Greek yogurt bowlGreek yogurt + berries + oats + peanut butter
Simple breakfastEggs + whole-grain toast + fruit
Plant-based plateTofu + quinoa + vegetables + avocado

You do not need stereotypical “fitness foods.” You need meals that provide useful nutrients in portions appropriate for your goals.

8–9. What Should You Eat Around a Workout?

Before Training

A meal with carbohydrates and protein within the hours before training works well for many people. Closer to the workout, favor foods you digest easily.

  • Banana + Greek yogurt
  • Oatmeal + protein powder
  • Turkey sandwich + fruit
  • Chicken + rice

After Training

Total daily protein matters most, although protein around training can support recovery. The ISSN generally recommends about 20–40 grams of high-quality protein per serving.

  • Chicken + rice + vegetables
  • Eggs + potatoes + fruit
  • Greek yogurt + oats + berries
  • Protein shake + banana

Your post-workout meal does not need to be magical. It needs to fit into a good overall diet.

10. What Foods Should You Avoid?

You do not necessarily need to eliminate pizza, bread, pasta, dessert, restaurant meals, chocolate, burgers, or practically any other individual food.

Your overall dietary pattern matters much more than whether you occasionally eat a particular food. Frequently consuming large amounts of highly processed, calorie-dense foods and sugary beverages can, however, make calorie management and nutrient intake more difficult.

11. You Probably Don’t Need a “Detox”

You do not need a juice cleanse, detox tea, fat-burning food, or elaborate supplement stack to start getting healthier. Your liver, kidneys, and other body systems already process and eliminate metabolic waste.

  1. 01

    Add a protein-rich breakfast

    Begin with one repeatable meal instead of rebuilding your entire diet overnight.

  2. 02

    Improve one snack

    Try fruit and Greek yogurt in place of one highly processed option.

  3. 03

    Prepare one more meal

    Pack lunch or add vegetables to dinner a little more often.

  4. 04

    Drink more water

    Build hydration into routines you already have.

Small changes repeated hundreds of times can produce much greater results than an extreme diet followed for two weeks.

12. Consistency Beats the “Perfect” Diet

One of the biggest mistakes people make is trying to completely overhaul their diet overnight—eating foods they dislike, avoiding restaurants, and measuring every gram.

A nutrition plan is only effective if you can actually follow it.

Your diet should account for your goals, schedule, food preferences, training demands, lifestyle, calorie needs, protein needs, and health considerations. The best plan is not necessarily the most restrictive; it is the one that provides appropriate nutrition and is realistic enough to become part of your life.


So, What Should You Actually Eat?

  • Eat quality protein at most meals
  • Eat plenty of fruits and vegetables
  • Use carbohydrates to support activity
  • Include reasonable portions of healthy fats
  • Drink enough water
  • Adjust calories to your goal
  • Favor nutrient-dense foods most often
  • Aim for consistency—not perfection
