Hi there! It’s Angela again. This time we come with another diet plan “900 calorie diet a day” – a topic that’s both popular and concerning. I want to be completely upfront with you from the beginning. While this diet isn’t as extreme as the 700 calorie plan, it’s still very restrictive and requires serious consideration. Many people ask me about this approach because it promises faster results than moderate diets. But here’s what I’ve learned from years of helping people – quick isn’t always better, and your safety matters more than speed. Let me share everything you need to know about eating 900 calories a day, including the real benefits, genuine risks, and whether this might be right for you.
What is a 900 Calorie Diet a Day?
A 900 calorie diet means you eat exactly 900 calories per day. That’s about half of what most women need (1800-2000 calories) and much less than what men need (2200-2500 calories).
Think of it this way – if your body is like a car that normally needs a full tank, you’re giving it less than half a tank. Your body will use stored fat to make up the difference.
This creates what we call a “calorie deficit.” The bigger the deficit, the faster you lose weight. But bigger isn’t always better when it comes to your health.
How Helpful Is A 900 Calorie Diet Plan?
Let me tell you when this diet might actually help:
- Faster weight loss than moderate diets: You could lose 2-3 pounds per week instead of the usual 1-2 pounds.
- Good for people with lots of weight to lose: If you’re significantly overweight, this might jump-start your journey under medical supervision.
- Short-term motivation boost: Some people use it for 2-4 weeks to see quick results and stay motivated.
- Medical situations: Sometimes doctors recommend this before surgery or for specific health conditions.
- Breaking bad eating habits: The structure can help you reset your relationship with food.
But here’s the reality check – most people find it hard to stick to. And when they stop, they often gain weight back quickly. It’s like a sprint instead of a marathon.

Facts About 900 Calorie Diet Plan
Here are the key facts you should know:
- It’s still considered very low calorie: Medical experts classify diets under 1000 calories as very restrictive.
- Your metabolism will slow down: Your body adapts to fewer calories by burning less energy throughout the day.
- You’ll lose water weight first: The first 3-5 pounds you lose will mostly be water, not fat.
- Muscle loss is common: Without enough protein and calories, your body might break down muscle for energy.
- It’s hard to meet nutritional needs: Getting all vitamins and minerals in just 900 calories is challenging.
- Results vary by person: Your age, gender, activity level, and starting weight all affect how this works for you.
- Most effective short-term: This works better as a 2-4 week plan rather than a long-term lifestyle.

Who Should NEVER Try This Diet?
Avoid this diet if you are:
- Under 18 years old
- Pregnant or breastfeeding
- Have a history of eating disorders
- Take medications for chronic conditions
- Are very physically active
- Have heart, kidney, or liver problems
- Dealing with depression or anxiety
- Already at a healthy weight
My Personal Tips for Success (If You Decide to Try)
- Start with medical approval: Get a check-up and blood work first.
- Plan for 2-4 weeks maximum: Don’t make this a long-term lifestyle.
- Take a multivitamin: You won’t get all the nutrients from food alone.
- Drink lots of water: Aim for 8-10 glasses daily to help with hunger and detox.
- Get enough sleep: Poor sleep makes cravings worse and slows weight loss.
- Meal prep on weekends: Plan and prepare your meals to avoid bad choices.
- Track how you feel: Keep a journal of energy levels, mood, and physical symptoms.
- Have an exit strategy: Plan what you’ll eat when you increase calories again.
Warning Signs to Stop Immediately
Stop the diet right away if you experience:
- Severe dizziness or fainting
- Rapid or irregular heartbeat
- Extreme weakness or inability to do daily tasks
- Persistent nausea or vomiting
- Severe mood changes or depression
- Hair falling out in clumps
- Any chest pain or breathing problems
Better Alternatives to Consider
Before trying 900 calories, consider these safer options:
- 1200-1400 calorie diet: Still gives good weight loss with better nutrition.
- Intermittent fasting: Eat normally but in a shorter time window.
- Portion control: Keep your favorite foods but eat smaller amounts.
- Add exercise: Burn more calories instead of eating drastically less.
- Focus on whole foods: Eat more filling, nutritious foods naturally.
What Happens After the Diet?
This is crucial – you need a plan for when you stop eating 900 calories:
Week 1 after: Slowly increase to 1200-1300 calories. Week 2-3: Add 100-150 calories each week until you reach maintenance. Long-term: Focus on healthy habits you can maintain forever.
Most people gain weight back if they don’t have a proper transition plan.
My Honest Opinion
I’ve helped many people with their weight loss journeys. Here’s what I’ve learned about 900 calorie diets:
The good: They work fast and can be motivating for some people. The bad: They’re hard to stick to and often lead to yo-yo dieting. The reality: Most successful long-term weight loss happens with moderate calorie reduction and lifestyle changes.
If you’re considering this diet, ask yourself:
- Are you looking for a quick fix or lasting change?
- Can you commit to the transition plan afterward?
- Do you have medical supervision available?
- Are you prepared for the physical and mental challenges?
Conclusion: 900 Calories Diet a Day
A 900 calorie diet can be a tool for weight loss, but it’s not a magic solution. It requires careful planning, medical oversight, and a solid plan for what comes next.
Remember, the best diet is one you can stick to safely. Sometimes slower progress is actually faster in the long run because it lasts.
Your health is worth more than any number on the scale. If you decide to try this approach, please do it safely with professional guidance.
And if 900 calories feels too restrictive, there’s no shame in choosing a more moderate approach. Losing weight slowly and keeping it off is much better than losing it fast and gaining it back.
Take care of yourself, listen to your body, and remember – you’re in this for the long haul. Make choices that support not just your weight loss goals, but your overall health and happiness.
