Discourged and feel like giving up :(

You can lose weight without specific exercise, if necessary. I know, because this is my situation also, due to injury. The objective is to achieve a healthy defecit between your total daily energy expenditure versus the calories you consume, and even for those with a sedentary lifestyle this can be achieved, and can still result in significant weight loss. Good luck.

I have knee trouble Im waiting on mri scan next week and on a waiting list for an operation, I still go to the gym 5 days a week just change up the routine. Machines I find work best and what I was advised by doc is treadmill, bike and crosstrainer - Ive designed an hours worth of routine that provides a great burn without putting any stress on my knee, my friend also suffers with siatica and uses the same routine as me. Its not easy and does take longer to shed the lbs but you will get there eventually. Ive been told by doctors not to run and I stupidly tried to last week, I lasted 1 mins 44 seconds before my knee popped out so lesson learnt.

"When you feel like giving up, remember why you started."

Im gonna go ahead and be the mean poster and say complain much?

Being healthy is a marathon not a sprint, you just going to give up and decide at 22 to spend the rest of your life being unhealthy and unfit? Pull yourself together, stop feeling sorry for yourself and comparing yourself to others. The point of making changes is to be the best YOU that you can be. You need to start being your own biggest cheerleader and push yourself. Do what YOU can, do YOUR best, and you'll see the results you want

Many people manage this without exercise at al. Some of my friends & I live in wheelchairs or are physically unable to exercise & are doing this on diet alone. If you want to succeed you can. Try swimming as it is non-weight bearing

I've only got about 20 lb. left to lose, but I feel like giving up. Due to sciatica and knee issues, I can't push myself very hard (the one time that I really need to!). Sometimes, even grocery shopping leaves me limping around.

I feel like no matter how I eat or how much I push myself to workout, it'll never be enough. People at this weight loss stage are running or working out like mad. I can barely do 20 jumping jacks without hurting myself. So, what's the point in trying anymore?

How did you get the issues with sciatica and knees? How long have you been a vegan? You can't give up at only 22 years of age.

You know I read this and was soooo tempted to get snarky - but I will try not to be.

I am going into hospital for a total knee replacement on Friday - since the beginning of the year I have been in agony most days, but that has not stopped me from working out 5 to 6 days a week - and most days get 500 calorie plus burns.....not one day have I said "I feel like giving up....."

When you have injuries you have one of two options - you can play the victim and go "poor me", or you can choose to find ways to work around your injury - Personally I chose the second option - my health and fitness is too important to me to not do that!!
At 52 I just realised that my body is going to pack up and challenge me in ways that is not always ideal - but that is not going to stop me from being the best I can be.

I do massive upper body weight workouts - and have increased hugely in my strength
I do "kick boxing" once a week - we need to go light on the kicking bit, I have to be quite "flat footed", but I pack a massive punch with my fists and elbows.
I swim and do aqua aerobics, most days I spend 30 minutes on a stationary bike, and I can also row on the rowing machine at the gym...
I also get a huge cardio workout from battle ropes, sledgehammer throws and kettle bell swings...

So - if you want this bad enough you can do it - good luck and I hope you find something that works for you :-)

I gave up almost a year ago and can't help but think... if I hadn't given up back then, would I be happy now? YES. Now I'm under a time limit. And when I feel like today just isn't my day, I stick to monitoring my food. You don't have to work out to lose weight! Focus on your diet for now, until more of the weight is off, and try what everyone else is saying and try yoga or swimming. Try things that won't strain your knee. I'm also young, and I hurt my knee bad more than a year ago. It hurts when I strain it. So I try my best to work around it until it improves.
Good luck and don't give up now!

do not give up- water workouts and cycling low impact workouts are needed-onwards and upwards
