For all the billions of words written on this topic it is really EXTREMELY SIMPLE. Eat less, be more active. It really is that easy. Of course it isn't easy, people don't want to make those lifestyle changes so they seek out alternatives.

Agree, but add eat/drink healthy.

I would advise you to also pick up some cardiovascular activity/sport (at least 2-3 times a week) to get the endorphins flowing, making you feel better in general and making it easier to keep up a healthy diet.

You don't need to eat healthy to lose weight, just less. You should however eat healthy for other reasons.

Day 1 (I won't be updating daily, but I am posting in response to your terrific, wonderful aid)

I've decided to run in a forest even though I don't know them at all. It wasn't that hard! I didn't get lost.

I managed to jog for 45 mins (sometimes really slow though) and I am almost completely dead now. But it doesn't matter, it was brilliant! I forgot how beautiful , non-linear the real world is.

I've decided to go for a walk with my gf today, if the weather still be as fine as it is now to explore further.

My knees and ankles don't hurt at all, so it's a good sign. My shape is terrible, but in next 2-3 weeks I think I will be able to run longer without spitting my lungs out.

Starting off with an intense 45 minute workout is the exact wrong thing to do. It feels good now, but in no time it will be too much and daunting.

Start slow.

Also running is bad.

This is the plan that I'm going to be following as soon as I'm up to it again. I made the mistake of walking for a few hours later in the day and strained one of my calves. I'm just about ready to start again though as my leg feels better.

The easy days are where you get to establish your form and make sure that they're working before you move on. Also, it's a good way to give your body some warning so that tendons can strengthen and muscles can get used to the motion.

EDIT: Running isn't necessarily bad, but you are mostly correct. The way that most people do it is just going to get them injured. But, with the correct form you shouldn't be placing that much stress on your knees and joints, especially if you're lubricating them regularly.

Let me put it this way. I have lost 50+ pounds extremely quickly twice in my life. Both times I ate whatever I wanted, just much smaller portions. Both times I was more active, but I didn't go crazy... just got off my ass, walked, did things, etc.

And no, I do not have a high metabolism. Quite the opposite actually.

Guys. I'm 22 yrs old. I am not overweight, my BMI is still far from being classified as overweight. It's just I have too much fat compared to muscles. (double chin + beer belly)

How running in woods could be bad for me? Isn't it the most primary instinct you could ever imagine? (running)

lifting weights - this is unnatural and wrecks your joints like mothercracker.

You still want to give your body some time to get used to the new stress that's being put on it. And I comletely agree with you about weights. Try old school calisthenics. It's incredibly cheap, all you really need is something to hang off of.

Running is great, but if you never did it you should be careful. Here's a very basic plan to get you running 30 min. in 12 weeks:

Wednesday - 30 min. walking.
Saturday - 30 min. walking.

Week 3

Monday - 5 times 2 min. running followed by 2 min. walking.

Saturday - 5 times 2 min. running followed by 2 min. walking.

Week 4

Monday - 4 times 3 min. running followed by 2 min. walking.

Monday - 3 times 8 min. running followed by 2 min. walking.
Wednesday - 3 times 9 min. running followed by 3 min. walking.
Saturday - 3 times 8 min. running followed by 2 min. walking.

Week 9

Monday - 3 times 9 min. running followed by 2 min. walking.
Wednesday - 2 times 10 min. walking followed by 2 min. walking.
Saturday - 3 times 9 min. running followed by 2 min. walking.

Week 10

Monday - 2 times 10 min. running followed by 2 min. walking.

Week 11

Monday - 2 times 12 min. running followed by 2 min. walking.
Wednesday - 2 times 14 min. running followed by 2 min. walking.
Saturday - 2 times 12 min. running followed by 2 min. walking.

Week 12

Try to run at a comfortable pace, and always do 5-10 min. stretching afterwards. Remember the stretches must feel tense but not painful.

Exactly. Every time I started to feel exhausted I stopped and start marching instead. Now it's one hour after my excercise and I feel completely fresh again.

I won't be pushing my body to it's limit from the start. Especially when I am almost sure that with decent amount of movement and without sweets I will start losing weight pretty fast. (I was slim entire life)
