How I Lost 25 Pounds in One Month is the most popular post on this website. Over 250 of you have e-mailed me to say that the diet is working for you and your family members, and I can’t tell you how happy that makes me.
Also, some of you have made comments or e-mailed me with questions and at this point, I am starting to get the same questions again and again, so I thought this would be a good time to update the post.
The most common question I receive is about the caloric need calculators, which are not the same today as 10+ years ago. Most of you were expressing your concern over the number of calories they calculated for you under my plan compared to what I remember eating way back then. So I went back online to try to find a calculator that would give me 1425 calories for a 5’6” female wanting to weigh 123 pounds. Guess what – I didn’t find one. All of the calculators returned a number of around 1630 for me now, at age 38. When I input an age of 27, the result came back at 1688, still a lot more than 1425.
Obviously, if that had been the number I was given back then, my results would have been different. Why are the calculators different now? I don’t know. But here is what I want you to do.
Most of us have a basal metabolic rate of somewhere between 1200 and 1300 calories per day. That means, that if you did nothing but lie in bed all day, you would expend at least that many calories. The taller you are, the higher that number, so if you’re 5 feet or below, use 1200, if you’re 6 feet or above, use 1300. At 5’6” I would use 1250.
Take the number that the calculator below gives you, add your basal metabolic rate, (1200-1300, depending on your height), and then divide that number by 2. For example, this calculator tells me I should consume 1630 calories to maintain a weight of 123. 1630 + 1250 = 2880. 2880 divided by 2 equals 1440. So I would start my diet by consuming only 1440 calories per day.
What I have shared with those of you who wrote me about this, is that after that initial 4-week period, my weight started to go below 123. Once I hit 118, I began consuming more calories. I’m just guessing here, but I’d say I leveled out at around 1600 or a dab more, which is in line with what the calculators today are telling us. I’m betting that they are more accurate today than the one I used over 10 years ago. That would make sense. But if you’re not getting the fast results you want, cut 200 calories per day and you will get there faster. Just don’t go below 1200.
Something else I did not go into in the last article is the fact that there are 3500 calories in a pound. There are a lot of websites out there who tell you that if you want to lose one pound per week, you need to cut back 500 calories per day. Keep in mind that that is from your current caloric intake. So, unless you know what that is, that number is completely useless.
What some of you did, was a double-whammy, where you took the number of calories for your ideal weight, then subtracted 500 from that, which left you way below 1200. No. No. No. No. And No. Remember, if you want to weigh 123, all you have to do is eat like a 123-pound person, and you will eventually become a 123-pound person. Don’t make it harder than what it is.
On the flip side, here’s what some of you have done. When you use the calculator, you input that you are a moderately active person. Doing that will automatically allow you more calories per day than someone who inputs sedentary. But then, you decide you’re going to keep up your work out. I’ve told you I’m okay with that, (not that you need my permission), as long as it doesn’t “mess you up” in other ways like I talked about in the previous article. But here is what you do next – you take the number of calories the machine at the gym says you’ve burned during your work out, and you add that to the number of calories the calculator gave you, forgetting that you’ve already allowed for those extra calories in your original calculation by saying that you’re moderately active. So if you want to use the numbers on the machine, tell the calculator you’re sedentary. Or forget the numbers on the machine, and stick with the number from the calculator. Any extra calories you burn at the gym will help you reach your goal faster. But only if you refrain from eating calories to make up for the ones you burn.
Losing weight is an exact science, but when you throw in too many variables, it becomes complicated. That’s why I like to keep it simple and not exercise in the very beginning. That’s also why I limited my diet, for those first three weeks, to only microwave meals and fast food. This leads me into my next topic.
I know that a lot of you out there who will be reading this are teenagers, more specifically, teenage females. And while my diet plan makes sense to you, your parents get a little suspicious of anything on the internet. They get especially suspicious when you start talking about buying microwave dinners to live on for a month and buying a book that only talks about fast food. You know what; they have every right to be suspicious because they are your parents. They are responsible for your well-being and they take that responsibility seriously. Be thankful that you have parents who care enough about you and your well-being to question what you do. Here’s what you can do.
One reader printed out my article and took it to her mother to read. Once she did, she understood it and actually helped her daughter with the system. She has lost 27 pounds, and her mother is starting to use the system as well.
If you have a parent who won’t let you buy microwave meals because of the chemicals that are in them, you will have to purchase a set of food scales and a book that gives you calorie counts for raw foods. You can still follow the system, you’ll just have a little more work to do. But you can do it.
If you are anorexic/bulimic, you can use this system to retrain your body back into a healthy way of eating in conjunction with your psychotherapy treatment. One reader says is helped her keep a sense of control – counting the calories and keeping a spreadsheet. I can see how that would help because in this system, you eat exactly what your body needs, and not one calorie more. So there’s no need to worry about gaining unwanted weight. It is very much about control, but it’s easy.
Most importantly, this is not about doing anything unhealthy. I want you to follow your intuition and do what feels good to you. If you think the caloric needs calculator is giving you too high a number, take a couple hundred off – just don’t drop below 1200. If you don’t like fast food or microwave meals, find what you do like that can keep the calorie count of. If you’ve developed a habit of exercising and don’t want to quit – don’t. Take those extra calories into consideration and enjoy them! This plan is rigid only in the number of calories you consume. How you arrive at your number is completely up to you. To weigh 123, you must think, eat, and act like you weigh 123.
Our natural state is well-being. All is well. I encourage you to look at the reasons you overeat. For me, it was just plain ignorance. That was it. If that’s what it is for you, because I believe that’s what it is for a lot of people, it’s okay. The good news is, once you find out you’re ignorant of something, anything, you’ve already become more enlightened. Can you see that? You don’t know what you don’t know. Once you become aware of a subject, you can start to learn about it, and come to know it. I overate because I did not remember that eating more calories than I needed would cause my body to store fat. I ate because something tasted good and I didn’t want to “waste” anything. Once that thinking changed, so did my eating habits, and so did my life.
Please continue to e-mail me with questions and/or concerns; I’m happy to assist you in any way I can. I will update the post again if necessary, you can register here so you don’t miss it.

Debra…
I am starting TODAY! I love this idea and the best part…I don’t have to learn to cook fancy meals. That’s always been my downfall. I am not good at cooking…AT ALL. This is finally a plan that will allow me to do what I need to do (loose weight) without me having to fear I won’t make it due to my lack of cooking skills!
Thanks a million!
Quiana,
Yes - no cooking! That’s kind of how it started in the first place. My husband was going out of town for 2 weeks and it was a sort of mini-vacation for me in that I didn’t have to cook for all that time.
You are going to be amazed!
Thank you so much for finally explaining this in words that I actually understood. After 27 years of weird and funky diets that never worked, I came across your website and read both of your articles. I started the diet on April 12th, and now, 2 weeks later I have lost 14 pounds. Those are the best results from any weight loss measures that I have ever started. My favorite part is that if I want a hamburger and fries on Friday night with my husband, then I can have it, just as long as I save up the calories all week.
Thanks so very much for this!
Dawn, Texas.
Dawn,
Thanks so much for sharing your results here and congratulations! It sounds like you got it - and the best part is that once you do, you never really “diet” again - it’s just how you live - and it’s so freeing. Thanks again for sharing your experience and please keep us informed.
First, I would like to tell you that I think it’s great that you’ve shared your story with the rest of us and provided a practical way to lose weight. Well, I started the plan two weeks ago. I lost 5 pounds the first week but now I’ve gained back 2 pounds. My current weight is 138 and I hope to weigh 125. I’ve kept a food journal and my calories don’t exceed 1350 per day. Should I incorporate exercise? I don’t know why I’ve gained weight. Any suggestions?
Jasmine
I believe either one of three things is happening.
1 – You’re forgetting to count some calories somewhere
2 – Your activity level has changed
3 – There is a medical problem somewhere
Starting with the last one first, have you been feeling tired or sluggish lately? Extra thirsty? Anything out of the ordinary?
For number 2, I tell people to not worry about exercise while trying to lose weight – were you on a program and stopped? I would not start a program now, but when you do your calculations, make sure you choose “sedentary.”
For number 1, I am not coming down on you, my mother does this all the time, “Well, that was a treat so the calories shouldn’t count.” And some people forget to count the calories in their drinks. Just make sure you’re getting everything.
Reflect on these possible scenarios and let me know what you come up with. We’ll keep working if we need to. It could also just be water weight gain – give it a couple of days and see if you suddenly lose 5 or 6 pounds in one day – I still do that!
Hi Debrah. I currently weigh 135 and want to lose 25 pounds. I’m 5′3″ and kind of confused but the calculator results. What calorie intake do you suggest I should follow? I also recently started to work out 2-5 times a week for 30 minutes. Thankyou gain for sharing your weight loss experience.
Meshi,
I suggest you start with 1525 per day and see what kind of results you get.
Let me know how it goes!
I recently read your articles, and I am going to give it a shot. I weigh 220 pounds, and 24 years old. I’m aiming 1400-1500 calories. Assuming i’ll lose weight on this, but i’m looking for results like you had… As you said you lost 20+ in a month! I don’t want to be losing weight for the rest of my life, thats for sure. Today is day 2. How often should I weigh?
Kelly,
Good for you! Weigh as often as you’d like. I weighed myself every day for a while, but then didn’t need to because my clothes were getting so loose. Then I went back to weighing every day as I got closer to my ideal and the results were less obvious in my clothing.
Just be sure to count those calories every day. Even if you have to go back and calculate it later, it will help you stay on track and not lose motivation.
Keep us posted!
Hi Debra,
I have slowly gained weight over the years and had 3 baby 5 months ago. I was doing a search last night for how to weigh 123 pounds and I found your site! I really want to see that number on the scales in front of me. I currently weight 181 and I am 37 yrs old and 5′6″. So lots of similarities to you. I have tried all kinds of diets and get so frustrated. But, I finally feel like I have hope. When you said your science teacher said if you want to weigh 123 pounds, you need to think and eat like you weigh 123 pounds. I’m not sure anything ever made MORE sense to me! I am going to start this tomorrow Feb 6th. I started a couple diets since November and my goal is 123 on May 23rd. Thank you so much for this site. I am excited to read some of your other posts. Thanks so much! Shelly
Hi, Shelly, and welcome! PLease keep in touch and let us know how you’re doing.
Hi Debora. I was reading your article and I just realized that my prom is literally less than a month away!!! Will this plan work if I really do it? I want to look good in my dress… haha
Thanks
There is no limit to what you can do if you make a decision, stick to it in every moment, and have fun with it. Enjoy the journey. The most important part is that when it comes time to eat, you make the choice you really want to make - don’t give in to temptation, or old habits. Planning is important - if you’ve made your choice ahead of time, it will be easier to execute it. Good luck and let me know if you have any questions!
Hi again…I’m really struggling with the plan…I am so stressed out that I give into my temptations…I get so upset at myself for giving in that I just keep doing it and I tell myself that I will start over again tommorrow and I keep eating…I kind of feel like an emotinal eater…sorry to vent so much…if I want to drop weight like within two weeks should I cut out any breads and pastas? What is the fastest way?
Miller,
Sorry it has taken me so long to get back to you - I’m away at a conference. The fastest way is to eat foods that have staying power. Things that will fill you up but not take too many calories. Lean proteins and high-complex carbs - lean meat and non-starchy vegetables.
The pattern you’re describing is exactly what my mother does. It’s what I call the “always on a diet except for when it comes time to eat” phenomenon. Since you are so stressed, and I’m going to assume that there’s nothing you can do about that right now, try planning your meals in advance as much as possible. That way, you won’t need as much willpower. Give yourself lots of options and be good to yourself in other ways.
Let me know if this helps. I’m here for you.
I have a question, you said that if it didn’t have a countable number of calories, then you didn’t eat it. This might sound stupid, but does this include vegetables that doesn’t have calories like celery and lettuce?
Kelley,
No. I didn’t explain that well. I just didn’t eat things if I couldn’t get the calorie count for them like a candy bar or microwave dinner or a meal from a restaurant - things like that - things you know would be substantial. Back then, I wasn’t in to vegetables that much. Now I live where I can grow my own and I love eating not only lighter, but healthier, too. I did have a book for celery and lettuce and like, though. I think it was something like 10 calories per cup. But I’ve heard many nutritionists say that those calories can almost be considered “negative” calories becuase they do so much to help you burn more calories just be eating them.
I hope that answers your question, but we can discuss it more if you like.
Did you have alcoholic drinks during your diet?
Monica,
I did not consume alcoholic drinks during my diet. I chose to save the calories for the good stuff. As with everything else in life, it’s a matter or choice.
hi Debra, I started this diet last week. I weigh 268 now and i set my goal as 220 because that’s what I graduated from high school as and that’s what my doctors have been telling me in the past as a reasonable first goal. Anyhow, my calorie intake at that level (deskjob, 6′ tall male) is 3100. This seems like a lot of calories! I have not been starving myself, the opposite actually, having a hard time getting every calorie in. Since starting this I have had a ton of energy and less depression, but not sure if the pounds are coming off. Should I stick with this or reduce the calorie intake to 2649 which would be my ideal weight 188. I have never weighed that much in my adult life and I have a large body frame. Thanks again, – William
I would go for the 188 since there is very little difference, calorie-wise, from where you are to where you want to be. Consistency is the key.
dear Debra,
thank you so very much for offering this new theory of weight loss! I cannot wait to get started. Here are my stats:
Number of Calories to Consume: 1200
Goal Weight: 95
Pounds to lose: 25-30 (hopefully by November! Is that possible?)
Hey Debra,
I’m very excited about this diet. I read both your articles. I started today
I’m a 25 year old male
I’m 5′10″ with a medium to large frame and I currently weigh 224 lbs
I’ve decided to set my first goal at 200 lbs!
My calorie intake came up at 2034 (which is: (2818 + 1250)/2), does that seem right to you?
once I get to 200 lbs I plan to setting a new goal of 185 and will probably try to stay there. Let me know what you think! thanks
Catherine - how tall are you? 95 lbs. seems thin. Keep in touch!
Edward - Any number is a good place to start. If you’re not seeing the results you want, drop by 100 calories per day until you do like what you see and how you feel. Keep in touch!
hey, it’s me again, just giving you an update…
so I’ve been doing this for a week now and have already lost 5 pounds! This is awesome, I’m not starving myself, I’m eating better and I feel more energetic everyday!
Fantastic, Edward! Keep up the great work and thanks for keeping us informed!
hey Debra than you for your blog . i love reading it and i already feel like my life is changing . my outlook is more positive . i am trying out this new way to lose weight .. i have tried slimming world..weight watchers and other random stuff and ive nevr really enjoyed them.. i like the idea of eating for the weight you want to be ..i will keep in touch and let you know how it is going ..i am giving myself 6 months to lose around 50 pounds ..i currently weigh 242 pounds and my healthy weight is 155 ..my greatest weakness is writing stuff down but i like the idea of didving the calories into breakfast , luch and dinner. please keep writing your blog ..i find it so inspirational
Hi Debra
Thank you for this informative website. After reading your blog I think this would be something I would love to try. I plan to start it from tomorrow. I’m 5′7 tall and weigh 220 lbs. My desired goal is to be 140lbs. My calorie intake should be 1595 but I decided I’ll go with 1500 calories. I was wondering is it ok if I workout? My workout should probably burn around 300-400 calories. I hope it works for me. I really need to lose 20lbs in a months time.
Thanks.
i started the diet a week ago today and consume about 1450 calories a day. i am 5′5 153 at start. It is a week later and im only 150.5. Do u see a dramatic weight loss later on in the diet? Eating less calories is actually not as hard as i thought! Please email me back!!
Elizabeth - For more dramatic results, cut back a little further, like 1350, especially since you don’t seem to be struggling any with the concept. Let us know how it works!
