What Exactly Is The 700-Calorie Diet?
Is 700 Calories a Day Good?
For most adults, 700 calories a day is considered a very low-calorie intake and is generally not suitable as a long-term diet. While it may lead to rapid weight loss, it can increase the risk of nutrient deficiencies, fatigue, and muscle loss if not medically supervised. Some people compare this approach with 900 calories a day to find a less restrictive calorie target that may be easier to sustain.
Quick Answer
A 700 calorie diet may lead to rapid weight loss, but it is generally intended for short-term use and often requires medical supervision. Most adults need significantly more calories to meet their daily nutritional requirements.
The 700-calorie diet is a type of very low-calorie diet (VLCD) designed to help individuals lose weight rapidly. It’s often used under medical supervision, especially for people with obesity-related health conditions who need to lose weight quickly.
The idea is pretty straightforward, you dramatically reduce your calorie intake, and your body starts burning stored fat for energy. While this can lead to quick weight loss, it’s not something to take lightly. Please note that there are risks involved, and it’s not for everyone.
For most people, this diet isn’t a long-term solution. It’s more of a short-term strategy that needs careful planning to ensure your body still gets the nutrients it needs to function properly.
Benefits of a 700 Calories a Day Diet
Every cloud has a silver lining, as does this one. Here are some benefits that you could reap from eating only 700 calories a day:
1. The Promise of Fast Weight Loss
Let’s be real- most people try such extreme diets because they want quick results. Eating 700 calories a day creates a big calorie deficit, and the weight tends to drop quickly, sometimes within days. While eating 700 calories a day may produce rapid results on the scale, it is important to balance short-term weight loss with long-term health and sustainability.
2. It Simplifies Your Choices
With only 700 calories to work with, meal planning isn’t overwhelming. You stick to a few nutrient-dense foods, which makes grocery shopping and cooking more straightforward. Having a list of low calorie snacks for weight loss can make planning easier while helping you stay within your daily calorie target.
3. You Learn Portion Control Fast
On this diet, you quickly understand how much (or how little) you can eat to hit your calorie target. This heightened awareness of portion sizes and calorie content can help you develop healthier habits going forward.
4. It’s a Motivational Kickstart
Seeing the scale move downward quickly can be super motivating. It’s like a jumpstart for your weight loss journey, giving you the push you need to commit to healthier habits.

The Dark Side: Risks and Challenges of a 700-Calorie Diet
While the benefits can be tempting, there are serious risks to consider:
1. Nutrient Deficiency
It’s tough to get all the vitamins and minerals your body needs on just 700 calories, leading to fatigue and weakened immunity.
2. Muscle Loss
Insufficient caloric intake can cause your body to break down muscle for energy, making weight maintenance harder.
3. Slow Metabolism
A drastic reduction in calories can trigger your body to enter "survival mode," slowing down metabolic processes and hindering future weight loss.
4. Mental Strain
The psychological effects of such a restrictive diet can lead to irritability and an unhealthy relationship with food.
5. Physical Side Effects
Common issues like dizziness, fatigue, and headaches can arise, making daily activities challenging. These concerns become even more significant when asking questions such as is eating 600 calories a day bad, since lower calorie intakes generally increase health risks.
Who Should Avoid This Diet?
Individuals with a history of eating disorders, those on specific medications, or anyone with underlying health conditions should steer clear of the 700-calorie diet. Pregnant or breastfeeding women should also avoid such extreme caloric restrictions. Always consult a healthcare professional before embarking on a restrictive diet.
People who perform physically demanding jobs or participate in intense athletic training may also struggle to meet their energy needs on such a restricted calorie intake.
What Happens After the Diet? Keeping the Weight Off

Losing weight is only half the battle, keeping it off requires a thoughtful approach.
A common mistake after very low-calorie diets is returning immediately to previous eating habits. Gradual changes tend to produce better long-term weight maintenance than sudden increases in food intake.
Or else you can end up undoing the process:
1. Slowly Add Back Calories
Gradually increase your daily intake by 100–200 calories per week. This helps your metabolism readjust without overwhelming your system. Many people transition toward 1000 calories a day before moving to a more balanced long-term calorie intake.
2. Stick with Healthy Choices
Focus on whole, nutrient-dense high protein foods. Avoid processed and sugary foods that can lead to weight gain.
3. Watch Your Portions
Even as you increase your calorie intake, be mindful of portion sizes to avoid overindulging.
4. Build a Sustainable Routine
Create a balanced eating and exercise routine that fits your lifestyle. Consistency is key to long-term success.
What Exercise Works Best With a 700-Calorie Diet?
Pairing exercise with a restricted diet can be tricky. You don’t want to overdo it and burn out. Here’s how to stay active without pushing your body too hard:
1. Stick to Low-Intensity Workouts
When you’re eating so few calories, your energy levels might not support intense exercise. Try beginner fitness programs, or low-impact activities like walking, yoga, or stretching are great options to keep you moving without overexerting yourself. Looking for fitness inspiration?
2. Add Light Strength Training
Incorporating light strength training can help you maintain muscle mass while losing weight. Try short, 10–15-minute sessions using bodyweight exercises like squats, lunges, or push-ups.
3. Skip High-Intensity Workouts
Avoid high-intensity workouts like HIIT or long-distance running, as these require more energy than your body can provide on a 700-calorie diet.
Staying Sane: Balancing Body and Mind While Dieting
A restrictive diet can be tough, not just on your body, but on your mind too. Here’s how to stay balanced and focused throughout the process:
1. Listen to Your Body
Pay close attention to how you’re feeling. If you’re constantly dizzy, fatigued, or irritable, it might be a sign that the diet isn’t working for you. Adjust as needed or consult a professional.
2. Practice Mindful Eating
Take your time with meals. Savor every bite, chew slowly, and avoid distractions like your phone or TV. This can help you feel more satisfied with smaller portions.
3. De-Stress Regularly
Stress can lead to overeating or emotional eating, which can derail your progress. Incorporate stress-relief practices like meditation, deep breathing, or gentle yoga into your daily routine.
4. Get Enough Sleep
Sleep is incredibly important for both weight loss and general well-being. Aim for 7–9 hours of quality sleep every night to help your body recover and stay energized.
