Weight just isn't going down.

Start eating more calories. The 1200 calories is the bare minimum and that is not taking into account any exercise. If you are eating a 1200 calorie diet you need to eat those exercise calories.

I experienced the same thing and I am still trying to figure out how many calories I should eat and at this point I am eating between 1370 and 1600 calories a day + my exercise calories and I have finally started to see weight come off again.

You need to find what works for you but you need to make sure you are eating enough

Sounds to me like you need to eat more.

He is a man so the minimum should be 1500 not the 1200 that MFP uses, which is for women.

When you first add calories back you may gain a couple of pounds as it sounds like your metabolism has slowed down and the only way to get it back up and running is to eat more.

When I started to eat more I gained for a couple of weeks and then hit a plateau where I no longer gained weight, don't freak out its a good sign because trust me it is much easier to stick to a healthy lifestyle than it is to stick to a diet and that is what you are going for, lifestyle change not a diet.

You have to change your goals and eat more. Based on the way you lost the first 30 pounds you have lost a lot of muscle mass - this slows the metabolism. Adding more cardio will have a detrimental effect. (Severe calorie restriction and cardio exercise cause muscle loss). Start incorporating some strength/reisistance training into your routine rather than more cardio.

Re-calculate your goals and change your weight loss goal. If you are set to lose 2 per week then drop it to 1 per week. You have put yourself into "starvation mode" (eating under 1200 (women only - men the minimum is higher - I think 1600) then exercising and burn 400 will put you under 800 NET and that is very, very bad).

The law of unintended consequences
Your body is an amazing feedback system aimed at balance and survival. Humans are at the top of the food chain because they are able to adapt to their environment. Every action produces a reaction. Every change in its environment triggers a survival response. It's important to keep that in mind when you plan your fitness program. If you treat your body as an enemy to be conquered, you'll produce unintended results.

For example, if you severely cut off the supply of food to your body, it will defend itself by slowing down its metabolism to survive starvation. The body will shed muscle mass the same way that you would throw cargo from a plane that was low on fuel, and it will reduce its thyroid activity to conserve energy. The body will also actually defend its fat stores. In anorexia, muscle loss can be so profound that fat as a percentage of body weight actually rises. Extreme carbohydrate restriction also causes muscle loss, dehydration, and slower metabolism, which is why even successful Atkins dieters can have a significant rebound in weight after they stop the diet (don't worry – the advice on this site will prevent that from happening).

As another example, if you put your body under stress through overexertion and lack of sleep, it will respond by slowing down, reducing muscle growth, and increasing your appetite for junk food, carbohydrates and fat. If you feed your body excessive amounts of sugar and quickly digested carbohydrates, and it will shut off its ability to burn fat until those sugars are taken out of the bloodstream.

This website will show you how to work with your body to quickly produce the changes you want. In order to do that, you need to take actions that push your body to adapt – to build strength, burn fat, and increase fitness. You need a training program, not an exercise routine. You need a nutrition plan, not a diet. You need a challenge, not a few good habits you usually try to follow except when you don't.

Setting the right goal
John Dewey once said that a problem well-stated is half-solved. If you want to reach your goal, you have to define it correctly. See, a lot of people say “I want to lose weight.” Well, if losing weight is your goal, go on a no-carb diet. You'll lose a lot of weight – some of it will be fat, a lot of it will be water, and a dangerous amount will be muscle tissue. You'll lose weight quickly, but you'll slow your metabolism and gain fat more quickly once you go off the diet. Trust me on this. I've been there, done that.

The problem is that you've set the wrong goal. If you want to look better, have more energy and enjoy better health, the goal is not simply to “lose weight.” The goal is to improve your fitness level and body composition. That means losing fat, improving your aerobic capacity, training your strength and defending your muscle tissue. You can't do that with a no-carb diet. You will do it using the approach you'll learn on this website. Trust me on this one too. I know what it's like to feel fat, tired and helplessly out of shape. The whole point of this site is to help others avoid that, by sharing lessons that I had to learn the hard way.

You need to eat more calories, or atleast eat your exercise calories. You would be suprised. You need to kick start your metabolism again.

you might want to switch your cardio routine, your muscles get used to what you do and they wont have effect on your weight. Another factor is that you start building up muscle and they are heavy , so measure your inches you might notice a difference... i hope this helps.

No it is not muscle, Can't build muscle on a caloric restricted diet such as this, as I said above muscle needs a caloric surplus to build any noticeable amount.

You are correct in that he should switch up the fitness routine, this should be done every 4-6 weeks.

Along with eating more healthy calories maybe you should change your gym routine.

Classic starvation mode.

ya gotta eat more! I'm a girl and I'm eating about 1500 calories per day. Each person is different but if you're net calories (after exercise) is below 1200-1500 you're body is going into starvation mode. Reset your goals and go from there....

As everyone has said, you're not eating enough. Here are some threads that help explain how to use MFP, how metabolism works, and why it's vital to fuel the body properly.

Your body could also be gettin used to the same routine. Change yiur cardio once in a while and maybe some weight training could totally change your body. I am trying to do this and hopefully it'll work. Good luck!

I agree, maybe you should start incorporating some weight training into your routine. Also, up your caloric intake...you can start slowly and then add more until you start to see the weight coming off again. You could also go see a nutritionist to make sure that you are eating the appropriate number of calories. MFP has me at 1200 calories a day, but my nutritionist says that it's ok to consume between 1200-1400. But, that is for me...Everyone is different.

Good luck!
