How To Lose 40 Pounds In Two Months With Katie

My name is Katie Marie Peterson and I started my weight loss journey on March 31 2013. After 2 months I managed to lose 40 pounds. When I began my journey I was 211 pounds and I was pretty devastated.

I’ve gone over that point and I’ve been working very hard and after 2 months I weighted 165.6 pounds which means I have lost 45.4 pounds. And that just feels incredible!

How To Lose 40 Pounds

I want to help anyone who’s trying to lose 40 pounds, pretty much telling what I’ve done. At the beginning I wasn’t as good but now I’ve been into a routine. By the way, routines really help to lose weight.

Work Out Hard

I’ve been working out every single day, 7 days a week. I know that sounds a little bit overboard but if you’re trying to lose 40 pounds in 2 months and you don’t want to gain it back instantly, you really need to exercise hard.

I’ve been working out 2 hours on the elliptical every single day. At the beginning of my weight loss journey I wasn’t able to work out as much as I am now. So I would maibe do 100 minutes a day and I didn’t realize there are resistance levels. I was doing level zero but I was still putting in the effort.

My eating wasn’t the best too, but if you really wanna lose even more weight than 40 pounds you need to start eating well from the very beginning. I write down every day what I eat and what I work out and it really helps me keep tracking. I looked at what I was eating and my first day of working out I was like:

“Oh I did really good, I had a bean and chees burrito for lunch and for dinner I had a hand full of Fritos and two tacos. I did good for today.”

I wondered why I wasn’t loosing as much weight. 🙂

I’ve been loosing consistently 5 pounds every single week and in the 8th week I lost 4 pounds in just 4 days. This means that what I’m doing is still working. This is why I wrote this post because I think these results will work on you too.

Eat Less And Healthy

I’ve been eating Cheerios like no other. They’re 110 calories per serving (one cup) and compare to other cereals they are low in calories and taste really great. I’ve been having a bowl of Cheerios every breakfast and then for lunch I have a salad and some grapes. I know no one likes salad but if you try to lose 40 pounds in two months you need to eat some.

For dinner I have another bowl of Cheerios and for snacks I have a couple of fruits.

Today I had almost a full pack of grapes for myself and then ran three miles! Tonight is this low calorie dish of broccoli, carrots, celery, onion, Brussels sprouts, egg whites and pistachios. Not seasoning or oil! Here is a pic:

Two different delicious lunch options: quinoa wrap or tomato basil pesto sandwich. Photo below:

So if you want to lose 40 pounds in two months, I recommend you to:

  • Work out for 2 hours on elliptical every single day.
  • Eat low calorie cereals like Cheerios, a lot of salad, fruit as snacks and veggies.

This program is extreme, so you’ll feel really tired. Be careful and if you don’t feel well, just stop this process. This is the way I’ve done it and it worked for me. Hope it works great for you too, and you’ll manage to lose 40 pounds in two months, as I did.

Here is a before and after picture. And yes, I have my boobs done. 🙂

I want to loose 40-45 pounds
All my life I have been 130/135 and for the past 2 years I ballooned to an extra 40 pounds (170) people love it since I used to be a really pretty girl and now I am very round in the face 😥


Also when I was a baby I had a terra time surgery and they messed up all the muscle in my stomach so that makes it hard


Okay, so I am a 15 year old female. I’m 5″8 and weigh 180. I’ve tried everything possible and it’s super hard for me to lose. I don’t have very good self esteem because my own parents and family tell me I’m fat and I look like I’m pregnant. I want to be about 125-130 lbs. can anybody help???

Hi , Well I have been lately reading a lot of books about weight loss and the way I have found best is that you should avoid all sugar Sugar in sense of bread chocolates biscuits potatoes etc. I mean all vegetables and fruits except banana , potatoe , too much grapes , mango. And walk for about 30-40 mins each day And you will see the difference But thE key point is to be patient This really has helped me to lose weight. And I would recommend Dr.Berg books they are so helpful. Lastly when you wake up drink… Read more »
I’m 5’9″ – 26yrs old I just had a baby so I gained a bunch of weight but pre pregnancy, I would run 3 miles at about a 9 minute pace (which is pretty slow)…it’d take me almost 30 mins to do my run. I’d eat 7 times a day but in portions that were very small; not to exceed 1800 calories per day. An example would be egg whites and turkey bacon for breakfast, low fat vanilla yogurt snack, sandwich (no more than 400 calories), 2 boiled eggs for snack, for dinner I’d have a salad, grilled chicken, brown… Read more »

I feel , I am 16 and I weight 190 ( I just got off my period) I want to be 140. Attalie, email me at and maybe we can work together!!!



Your own parents tell you you’re fat? That. Is. AWFUL. Honey, you’re BEAUTIFUL. If you want to lose weight, do it for you, and not for anyone else. Try low calorie meals, lots and lots of protein like chicken and turkey and stay away from carbs. Maybe take small walks around the park or your neighborhood too


What if you dont have an eliptical???Are there any exercises you can do?


Just go out and run!

You look amaizing! Great job! Thank you for sharing?


Could you possibly tell me what exercises you did so I know the best possible ones and what you regularly eat or is what you had already mentioned is all you eat… because personally I wouldn’t be able to eat the same thing everyday xD please and thanks so much


Her before and after is a 94lbs difference in 4 months! Look her up on youtube and insta: misspinkmeltsaway

Your after pic can’t be at two months as it takes quite a while to recover from a boob job and there’s no way you can exercise for two hours a day after surgery. If people want to lose weight fast but in a healthy way then you need to read Eat To Live by Dr. Fuhrman or start doing green smoothie cleanses every month (10-12 days per). Everyone please keep in mind that not everyone can lose weight fast, younger peeps lose faster than older folks and men lose weight faster than women. Do it healthy and you can’t… Read more »

Her before and after picture is 94lb difference in 4 months go check out her YouTube video

Hi Katie, This does not seem like a very healthy diet to promote on the internet. I am sure younger girls than you are looking at this and going I’m going to do this. Do you really think eating the same thing everyday is good for you. I think you should become more educated on nutrition and exorcise before posting things like this online and calling it a program. A lot of people may see this as a good way to loose weight fast but not everyone looking at this is an adult. I am only telling you this because… Read more »
