Everyone is always looking for the best ways to lose weight which is fine, but do yourself a favor and don't buy into all the hypey garbage you see online and off. If you want to try a pill or a special diet that's fine, especially if you only want to use it for a short time just to jump start your weight loss, but do not believe that you can lose weight overnight with absolutely no lifestyle changes… you will only be setting yourself up for failure.
The best approach to weight loss is to look at it like a lifestyle change rather than a "diet". Diet makes it seem like it is something short term where lifestyle change makes it seem more like what it should be, a lifestyle change.
Approaching it from this point of view will make it easier for you since it will take off that pressure to have results immediately. Any weight you lose within days of starting is usually only water weight anyway, not fat lose. Do not set yourself up for failure by having unrealistic expectations.
Your first step should be to find a sensible and healthy eating plan. Make sure you have lots of lean protein and a reasonable balance of fat and carbs. Also, make sure you drink plenty of water every day. It's usually recommended that you drink half your body weight in ounces of water every day.
For example, if you weigh 126lbs that means you should drink about 63 ounces of water everyday to keep your body hydrated and to flush out toxins.
After that point you should set up a sensible exercise plan to workout and lose weight. Again, making a plan is a great start. You don't have to go to extremes, you need to start at what every fitness level you already have and start adding on as you are able to. Something as simple as taking your dog for a walk, using the stairs at work and parking a little further from your office can be simple, easy changes you can make.
If you feel like it, and your doctor says it's ok (you should always check with your doctor before you start a diet and exercise program, especially if you have underlying health issues) than you can step up your workouts.
The most important thing you can do is to find a workout that works for you. If you hate the treadmill with a passion, then don't use the treadmill. The best thing you can do to ensure your success is to find an activity that you like, that way you will stick with it.
There are many things you can do to lose weight and the best ways to lose weight are the ones that provide your body with the nutrients you need and finding a sensible exercise plan. Make it a permanent lifestyle change, take it one day at a time and keep realistic expectations and your chances of success are greatly improved.
