How can I lose weight fast?
The fastest you should attempt to lose weight is about 1 to 2 pounds of fat loss per week.
Notice I said fat loss.
When you attempt to lose weight, you should ONLY want to lose fat.
If you try to decrease calories too much and add too much exercise all at once, you'll start to lose precious muscle mass.
I call muscle mass precious because it's ACTIVE tissue that works for you all day long.
Excess body fat is inactive tissue that doesn't work for you at all. It's worthless.
So work on losing body fat and NOT muscle mass.
Change your diet. Calculate how many calories you should be eating using the WLC System Diet Calculator. Start using the WLC System.
Eat the healthiest foods only.
Do cardio workouts.
Increase your activity. Track it with a Fit Bit or other activity tracker. This is one of the best first steps you can take. Set a goal of 10,000 steps per day for the first month. Hit it every day of the week (or rest on Sunday). Then increase your goal to 11,000 steps per day the next month. The fat will start going away!
Fat loss takes time. To do this the right way, you need to focus on fat loss of 1 to 2 pounds per week. 2 pounds is the maximum as this is starting to reach the area where muscle loss might occur. If you instead slow it down to 1 pound of fat per week, you'll be able to keep all your muscle mass and possibly even build more (with the right weight lifting workouts).
In my opinion, fast weight loss IS 1 to 2 pounds per week!
Some people want up to 10 pounds of weight loss each week.
If you're getting that much weight loss per week, 100% without a doubt, most of that is water weight. You aren't losing much body fat at all. Some of it will be muscle and some will be fat.
