I have tried a handful of things over the years to lose weight. Dieting, eating healthier, and exercise. But there was really only one thing that caused me to lose a lot of weight, and lose a lot of weight quickly. The thing that caused me to lose a lot of weight and lose a lot of weightly quickly was intermittent fasting. Th first time I did intermittent fasting I literally jumped straight in to the warrior diet. This was eating two healthy meals a day, no snacks, and then not eating anything for 20 hours, and only consuming water or black coffee with no sugar ofcourse for 20 hours. The first time I did this you wouldn't actually believe how different I looked withing two week. Literally two weeks and everyone was saying to me I have lost weight. So I done this diet for over a year. But I did go back to sometimes eating fattening food and sometimes drinking alcohol. So maybe on average a few days of the week I was drinking alcohol and eating fattening food, but then the rest of the week I done this strict intermittent fasting. While I was doing this for a long time I didn't lose any more weight, but I didn't gain any weight either. I just remained the same weight for a long time. But with going from this strict healthy eating and intermittent fasting for days, and then other days drinking alcohol and eating crap and then going back to the healthy diet and intermittent fasting. These changes in diet and eating literally kept making me feel unwell, like it was a shock to my body. I seemed to feel fine if I only done the health diet and fasting, or I did sometimes drink and not eat the best but I wasn't doing the intermittent fasting at all. But it seemed to be switching from one to the other all the time did actually make me feel unwell. This was quite difficult to me. Because it literally felt like I could never let lose ever, and sometimes enjoy my self by having a drink and maybe eating some junk food or fast food. I also have issues with quite severe ocd, so I became very obsessed with intermittent fasting. It just somewhat made me feel like a robot. It was like I can eat now, I must stop eating now. I can drink something else apart from water or back coffee now, I must only drink water or black coffee now ext. The reason for this is because while you're in a fast you don't want to consume anything that rasises your insulin levels enough that basically break your fast. Water does not raise insulin, and black coffee on it's own doesn't raise insulin enough to break a fast. But many beverages would raise insulin enough to break a fast. But basically I am frustrated with all this weight I am piling on. It seems eating health the majority of the time and then occasionally drinking and not eating as good isn't enough to maintain my weight, it is actually piling weight on me. From what I have read exercise is only about 15% to do with weight loss, and that is people who push exercise to the limit. Generally exrercise is only about 5% to do with weight loss for most people. So I am really wondering what I can do to get this weight back off quick. It's frustrating how easily and quick weight seems to go on me. Ok if I was always drinking and eating crap then fair enough. But I am eating healthy the majority of the time and only drinking and maybe not eating good one or two days a week, and boom this is causing rapid weight gain. Like I say when I done the intermittent fasting most of the time and sometimes drank and not eat as good, this didn't make me lose weight, but it didn't make me gain any weight wither. I just maintained my weight. What do you guys do to succuesfully lose and miantain weight?
