Why am I not losing??????

You are gaining muscle with all the exercise which in the long run will help you burn more fat...keep it up. You may try using the measurement tracking in addition to the weight, with all your exercise I would bet that you will see results on the body even if the scale isn't moving right now

Maybe your body is just trying to adjust to all the changes...you have made lots of changes all for the better...but maybe your body is thinking what the heck is she doing to me. From your post it seems you are following all the things that I have seen/heard suggested by others on the forums. Don't give up or get discouraged...like you said you feel better and that is really the most important part of this journey.

It's possible you've started building muscle, which weighs more than fat. I had the same thing happen to me as well, and I totally freaked out, but it's probably just muscle. You should start loosing weight again soon, especially since muscle helps to burn fat. Good luck and don't stress. Every good choice you make is a step in the right direction! Don't forget that!

Thats a Myth that Muscle weighs more then fat.
Muscle Does Not Weigh More Than Fat (five pounds is five pounds), but it is Much Nicer to Look at

5 Lb. Fat vs. 5 Lb. Muscle
As you can see, the 5 lbs. of fat is much bulkier than the 5 lbs. of muscle, but five pounds is still five pounds. Muscle does not weigh more than fat.

Fat is bulky and lumpy so if you carry an extra five pounds of fat, you'll be lumpier than with five pounds more muscle. A five pound pile of fat will take up more space (volume) than a five pound pile of muscle; but five pounds is still five pounds, so for those of you that don't "get" English, you cannot say one thing weighing a certain weight weighs more than another thing at that same weight. It's a common joke to play on an 8-year old. The correct way to state the muscle weighs more than fat scenario is, "Muscle is heavier by volume than fat."

A woman weighing 150 pounds with 19% fat will look much smaller (and be much healthier) than a woman at 150 pounds with 35% fat. They weigh the same, yet the composition is different. Because muscle is more dense than fat the person with less fat and more muscle will look smaller.

Stop being so obsessed with body weight and start paying attention to body composition. How much body fat do you have compared to muscle? Simply seeing how much you weigh isn't very helpful.

i know it is really hard not to get discouraged but something i have learned is not to be a slave to the scale!!!!!! you may have lost some fat but replaced it with lean muscle. what you need to do is start taking measurements, that is truly the key to how successful you are. and you are essentially new to diet and exercise so it will take your body some time to adjust. so keep your chin up!!!! you are doing a fabulous job by the sound of it.

Does Muscle Weigh More Than Fat?
Compact and efficient, muscle burns more calories and can bring faster diet results.
By Kristen Stewart
Medically reviewed by Pat F. Bass III, MD, MPH Print Email Like a lot of people, you might think that muscle weighs more than fat.

“When I hear this statement, I always think of the old riddle: Which weighs more, a pound of feathers or a pound of bricks?” says Laura Stusek, MS, fitness coordinator for Westminster College in Salt Lake City, Utah. “A pound is a pound!”

Muscle vs. Fat: Clearing Up the Misconception

Common sense tells us a pound of muscle and a pound of fat have to weigh the same, but they do differ in density. This means if you look at five pounds of muscle and five pounds of fat side by side, the fat takes up more volume, or space, than the muscle. That’s important when you’re on a diet and part of your goal is the lean look of muscle, not the flabby look of fat.

So why do people say muscle weighs more than fat?

“I find people make this statement when they put on weight,” says Stusek. “One person will say, ‘I gained three pounds and I’ve been working out.’ The good-friend response is, ‘It’s all muscle.’ And while this is a very comforting thing to hear, it’s just impossible to gain three pounds of muscle in a week. It is common for exercisers to lose fat and gain muscle without a change in body weight, so I understand why people often get frustrated.”

Muscle vs. Fat: The Truth

The first step in a successful diet and exercise program is to banish the idea that muscle weighs more and is therefore bad. In fact, Stusek recommends tossing out the scale altogether.

“I try to get people to think about how they are feeling, how their clothes are fitting, and how their body has changed,” Stusek advises. “It’s a hard thing to do sometimes. The focus should not just be the number on the scale. If we only did things to make ourselves weigh less, we wouldn’t necessarily be healthier.”

Muscle vs. Fat: The Benefits of Muscle

In fact, not only should dieters stop thinking of muscle as the enemy, they should embrace it as their friend.

Muscle boosts a person’s metabolism, so a pound of muscle will burn more calories at rest than a pound of fat. What does this mean? Even when you’re not exercising — you could be sitting on the couch watching TV — you will be burning more calories just by having more muscle.

Muscle has other benefits, too. It’s critical in improving bone density and helps prevent the loss of muscle mass that occurs with aging, allowing people to stay active as they get older.

Muscle vs. Fat: Ways to Gain Muscle

There’s no doubt cardio workouts such as jogging, cycling, and walking are important for calorie burning and good health. But strength training is vital, too. “Of course, we always think of lifting weights to put on muscle, and many fear they will become ‘bulky,’” says Stusek. “Women need to stop worrying about this.”

There are plenty of options to build muscle, ranging from free weights to resistance bands and even plain old soup cans. Stusek recommends enlisting the help of a personal trainer to design a balanced, full-body workout for the best results. “Or if you want to bulk up, lift heavy weights and do low repetitions,” she says. And two or three times a week, with at least one day off in between for muscle recovery, is sufficient.

Ultimately, building muscle mass is a good thing. So find some enjoyable exercises and get lifting.

It sounds to me like it might be water retention from muscle build. The above poster is right, it's a myth that muscle weighs more than fat, however, when you're building muscle, that tissue will retain water while it's repairing itself.

Keep up the good work, make sure you're eating as well as you can - and by that I mean avoid processed foods as much as possible and watch your sodium, carb and fat totals, not just calories.

Feel free to friend me if you'd like. You and I are about the the same weight so maybe we can help each other along.

Hey,

Congratulations on making a significant change in your life.You have made a great start in the first month.It is very easy to get carried away with big losses at the beginning and grow to expect them each and every week.The reality though is that the amount of weight that you have lost already is a good and safe amount in the timesacle mentioned.I dont know what weekly goal you have set with mfp,but I expect that you wont be too far away from that.Someone has already said that you have initiated a lot of change in a small amount of time and your body will take a little time to react to this.I have also noticed a lot of people losing big one week and small or stationary the next.I am no expert but I think that you are by the sound of it doing great and by making exercise part of your life this can only carry on.
Please dont go putting yourself under pressure to achieve something that might not be sustainable going forward,just make the changes subtle and manageable and enjoy the new you.....

Sore and newly worked muscles wil retain water. Looking at this not so literal I know what you mean by muscle weighs more than fat, basicly muscle is dense vs fat but it takes a lil bit to build muscle not just overnight. Don't get on the scale for a month, if your eating right and drinking water you can't go wrong.

with doing p90x u are going to gain muscle so that is most likely why...but thats a good thing as ur muscles get more toned u will start burning fat quicker

MUSCLE does not weigh more than fat!!!!!!!!!!!!!!!!!!!!

That's a myth. A pound is a pound is a pound.
