Diet is 90%. You cannot exercise enough to keep the weight off if you eat like shit every day. This is quite literally math. 1 hour of walking = 200 calories. 1 hour of running = 600 calories. great source You know how many calories is in, say, a bagel and cream cheese? 500. You know how long it takes you to eat it? 15-30 minutes, maybe? I guess a small specific example of "How do I eat healthy?" every day that helps explain some of my broader time management: Dude, I eat a salad. Every. Day. Every fuckin day at lunch I eat a soup and a salad. I get a small soup and the salad can be as big as I want because you know what? F'n veggies, that's what. You can eat as many vegetables as you want, any day, any time, even if you're trying to lose weight, especially if you're trying to lose weight. I used to just skip breakfast but I'd get hungry so now I have a yogurt, one of the nice greek yogurts, the shit that's got 25% of my daily recommended brotein (yes brotein) intake in it. For me, for eating healthy, what works is routine. Just today someone was giving me shit about eating the same thing for lunch every day. You know what? When I eat a yogurt for lunch and a salad for dinner, I can go out drinking that night and maintain my weight. If I just eat meat & veggies for dinner I can lose weight if I want. If routine is what works for you then do it. I eat soup and salad and yogurt every day because it helps me feel good about myself and the contribution I'm making, every day, to eating my veggies and maintaining my weight. Sure I could have had steak and fried potatoes for lunch. And yeah it would've tasted great! (I guess...I kind of like my soup/salad thing) but I wouldn't have made a step forward to being a healthier person. Be healthy today. Don't wait for tomorrow.
