would you cheat diet.if you dont reach your goals

It's good to see that you're optimistic and congratulations on your weight loss so far
However, in my medical degree (I'm studying to be a doctor) I have been told time and time again that the average amount of weight that medications such as Orlistat help people to lose... is 2-3 kg (4.4-6.6 lbs) and that is over about 1 year or more. Those drugs really not great. They don't do much at all. The side effects aren't worth it, either. Steatorrhoea (horrible bowel movements) and having to wear panty liners because of the oil and fat that leaks through your gastrointestinal system are both pretty horrid, from what I've read and been taught. Plus they're expensive.
I'd recommend just reaching your goals with exercise and diet modifications - honestly, you'll see a MUCH bigger result from then than any of those drugs could provide.
If there were a miracle drug that helped you to lose loads of weight while you just ate normally, and there were no side effects, I'd so go for it! But the reality is that these drugs do virtually nothing.
If you're really desperate to lose weight (e.g. because you have serious sleep apnoea and could die if you don't lose weight), then I'd recommend enquiring about gastric bypass surgery. That is really the only way you can lose weight without diet and exercise modifications. But from looking at your profile pic, I don't think you'd be big enough to qualify for it.
Good luck! MFP has helped me to lose 39 lbs in 4 months, and is a fantastic place to be!

Don't take this the wrong way but I think you are looking at this weight loss thing a little wrong. You are looking for a short term quick fix , i.e. drugs etc and looking to lose an awful lot of weight in a short period of time. If you truly want to make a long term change you have to start changing your frame of mind on the situation. Do you want to lose this weight forever or just temporarily? Because using drugs to do it and not changing your eating habits, binging in hopes that it will be ok is not the answer. Just my opinion.

Cheating will always affect your maintenance, no matter what type of cheating you do. The only way to make sure that your weight maintenance is on par is to learn good eating habits and proper exercise on the weight loss journey and to keep those lessons in mind during your maintenance period. Whether you cheat using drugs or any other method, when you stop "cheating" you are much more likely to gain weight back, and even moreso than before, because you aren't simply doing proper nutrition and exercise. Even if you do eat right and exercise while taking those drugs, the side effects could wreck your body, and when you go off the drugs, your metabolism won't be the same as it would have been without the drugs. Weight loss drugs, just like any other drug, mess with your internal balance (so to speak) which doesn't just go back to normal afterwards like flipping a switch. Your whole situation reminds me A LOT of people who undergo weight loss surgery in that afterwards, they have a hard time dealing with nutrition and exercise because the surgery changes their "normal" to something that they have to "re-learn" if that makes sense to you.

In other words, just exercise and eat proper nutrition. Even if you don't make your goal by Christmas, you WILL make your goal and you will have that satisfaction of "I did it!" no matter when you cross the finish line.

Also, sure you can cheat and eat junk and not exercise and lose "weight" ...but that's not all you'll lose... you'll lose your health, CV fitness, muscle tone and strength...what gains can you expect? Probably an increased risk of heart failure, bad blood pressure, liver/kidney problems, cancers from all the rubbish you're eating, inadequate nutrition in terms of the ratios of macros. Possibly still get diabetes, other illnesses, more susceptible to infections...so you'll be a skinny fat person inside. It's not unheard of skinny people with bad diets to suffer all the above. On top of that, your gut probably won't be functioning properly and you could have all sorts of unpleasant effects as a result of that!

You need to grab the lifestyle change by the scruff of its neck and reign it in and start now, the longer you leave it, the harder it will become and the later you'll start losing weight and the sooner you'll be adding to your risk level of horrible disease.

Please, start exercising, just 30 minutes moderate exercise a day, such as a brisk walk contributes and will make a difference, maybe in the not so distant future, take up running or go to a gym or start cycling to get some more vigorous exercise in to really help make your heart strong, muscles effective and help lower your blood pressure!

Don't cheat! Cheating is never worth it and always catches up with you!
