What does caloric deficit mean? A caloric deficit is when you consume fewer calories than your body needs to support basic functions and activity. This caloric imbalance forces your body to burn stored fat for energy, resulting in weight loss.
You can create a calorie deficit by:
- Eating fewer calories
- Increasing physical activity
- Or both
This infograph is based on food intake alone and is only an example.
Sustaining a small calorie deficit of around 500 calories per day leads to gradual, sustainable weight loss over time. Caloric deficits are a foundational component of any science-backed healthy weight loss plan.
Determining Your Caloric Needs
Let’s talk about figuring out how many calories you need each day. This magical number for calorie needs is your maintenance calories.
Your maintenance calories depend on stuff like your basal metabolic rate (BMR) , activity level, and body stats.
So, what’s a good calorie deficit for you?
Our online calculator can give you a rough estimate. To get the most accurate number, track your food intake for 10 days and keep your activity level the same.
- Weigh yourself each morning wearing the same thing
- Track every little nibble in a food diary app
- At the end, take your total calories eaten and divide by 10
Voila! Now you know your daily calorie requirement to maintain your weight. Pretty cool right? Knowing this number is super important to achieve a calorie deficit.
How to Calculate Your Calorie Deficit
Alright, time for some math! I know, I know, but calculating your calorie deficit is crucial.
First, take that daily calorie need we found earlier. Let’s pretend it’s 2,000 calories per day.
Now, subtract 500 calories since that’s the recommended daily deficit. Removing 500 calories a day will burn about a pound a week.
So for our example:
2,000 maintenance calories
- 500 calorie deficit
- = 1,500 calories per day to lose weight
As you lose weight, your calorie needs decrease. So every 10 pounds or so, recalculate your maintenance calories and adjust your deficit.
- Use our online calculator
- Or repeat the 10-day tracking
Keeping your deficit in line with your needs ensures steady fat loss. No need to do huge deficits! A 500 calorie per day cut is plenty. You just need to consume less calories than you burn.
How to Create a Safe Caloric Deficit
Now we can get to the good stuff – actually making that calorie deficit happen!
There are two main ways to create a deficit:
- Eating fewer calories
- Burning more calories through exercise
Most experts recommend a healthy calorie deficit of around 500 calories per day for steady, sustainable weight loss. This should lead to about 1 pound of fat lost per week.
You can make this deficit through:
- Cutting 500 calories from your diet
- Burning 500 extra calories through activity
- Or a combo of both!
Some key tips:
- Don’t cut calories too low, especially if you’re active. Women should eat at least 1,200 per day and men at least 1,500. Anything less can backfire.
- Add protein, fruits and veggies to keep you full.
- Watch your portions using smaller plates, weighing food, etc.
- Stay hydrated! Thirst is often confused with hunger.
- Take a multivitamin to fill nutrition gaps, if needed.
- Avoid processed foods to make it easier.
Optimizing Your Caloric Deficit Diet
Now for the fun part – let’s talk about the actual food! Optimizing your caloric deficit diet is key for losing fat, not muscle.
Focus on getting enough protein. Try to eat protein with every meal and snack. Good sources are:
- Lean meat and poultry
- Fish and seafood
- Beans, lentils, and soy products
- Greek yogurt
- Protein powders (if needed)
Fruits and veggies are your friend. Aim for 5 servings per day minimum to stay full and get nutrients. Some easy ways to add more:
- Keep washed berries and baby carrots on hand for snacks
- Add spinach or kale to your morning smoothie
- Roast a big batch of vegetables to add to meals all week
Choose mostly whole, unprocessed foods like:
- Whole grains (oats, quinoa, brown rice)
- Natural nut butters
- Nuts and seeds
Some other tips:
- Cook at home as much as possible for portion control
- Meal prep on weekends to set yourself up for success
- Drink water before meals
- Use smaller plates
- Season foods with herbs and spices instead of salt
The key is finding an eating pattern you can stick with long-term! Don’t be afraid to experiment. And remember to treat yourself on occasion in a balanced way.
Troubleshooting an Ineffective Caloric Deficit
Uh oh, the scale isn’t budging even though you’ve been diligently eating in a calorie deficit? I’ve been there, and it’s frustrating. But don’t give up hope! Here are some possible reasons:
- You’re eating too few calories so your metabolism slowed. Try increasing by 100-200 calories.
- You’ve hit a plateau after initial loss. Be patient and keep going! The scale will budge again.
- You’re gaining muscle while losing fat. Focus on how your clothes fit.
- You have an underlying medical condition like thyroid issues or PCOS. See your doctor.
- Your medication may be the culprit. Ask your doctor about alternatives.
- You’re eating more calories than you think. Double check your tracking.
- You’ve lost weight but replaced fat with water. It will eventually drop off.
Be kind to yourself! Plateaus and hiccups happen. Stay consistent with your deficit and make adjustments if needed.
Consider seeing a registered dietitian or your doctor if you’re really stuck.
Maintaining Weight Loss After Reaching Your Goal
You did it! You’ve reached your weight loss goal. But the journey isn’t over – next comes maintenance. Here are some tips:
- Gradually increase your calories to match your new weight. Use a calculator or repeat the 10-day tracking method.
- Keep eating plenty of protein, fruits, vegetables, and whole grains. Don’t revert to old eating habits!
- Weigh yourself weekly to catch any gains early. Adjust your calories if needed.
- Continue exercising to burn extra calories and keep your metabolism up.
- Practice mindful eating and listening to hunger/fullness cues.
- Allow yourself occasional treats and dining out, just keep portion control.
- Seek support from friends, family, or professionals to stay motivated.
Be proud of your hard work! With some diligence, your new healthy lifestyle can become habit.
Setting Yourself Up for Long-Term Success
We’ve covered a lot of ground on utilizing calorie deficits properly. But knowledge alone won’t lead to success – you need the right mindset and tools. Here are some final tips:
- Make small, sustainable changes over time rather than overhauling everything overnight.
- Surround yourself with positive people who will support your journey. Misery loves company!
- Develop awareness of your habits and triggers through journaling or an app. The more you understand your patterns, the better you can manage them.
- Focus on internal motivation – how you’ll feel with more energy, confidence, etc. External motivations often fade.
- Deal with stressors and emotional issues rather than burying them in food. Find healthy coping strategies that work for you.
- Be patient and keep going, even when the scale stalls or you have a setback. Progress isn’t linear.
You’ve got this! With some self-awareness and commitment, your healthy lifestyle will stick.
Frequently Asked Questions
Below are some common questions about caloric deficits. Let’s tackle them!
How many calories should I cut to lose weight?
A daily deficit of about 500 calories is perfect for steady, sustainable weight loss for most folks. This should have you losing about 1 pound per week.
What happens if I eat too few calories?
Eating very low calories can actually slow your metabolism down big time. Not what we want! It may also cause fatigue, headaches, irritability, and even loss of muscle.
Can I build muscle on a calorie deficit diet?
Absolutely! The key is to keep strength training and get enough protein. Your muscles will thank you.
Why am I not losing weight on a calorie deficit?
Plateaus happen! Check your calorie tracking accuracy, adjust your deficit if needed, rule out medications or health conditions, and be patient. The scale will budge again.
How much protein should I eat on a caloric deficit?
Aim for 0.5-1 gram of protein per pound of body weight daily. So if you weigh 150 pounds, eat 75-150 grams of protein. If you work out, aim for at least 1 gram per pound of lean muscle mass.
How long should I stay in a caloric deficit?
It varies based on your weight loss goal, but usually reducing calories for 4-6 months is safe for most people. Take a maintenance break if you plateau.
Will I gain the weight back after I stop the deficit?
Not if you transition properly! Slowly increase calories and keep eating whole, nutritious foods along with regular activity. Developing healthy habits is key.
