Losing weight in the best of times is not easy. But aiming for rapid weight loss adds the extra burden of doing it with a deadline. Asking for more means you have to put more into it. On the mental side, you'll need determination, specific targets, a detailed plan, and extra discipline to stick to the plan. On the physical side, you'll have to do even more exercise than you would if there was no hurry. You'll also need to make changes in what you eat. (Note: Be sure to talk to your doctor before starting any weight loss program.)
Rapid Weight Loss - Planning is Critical
First the mental items. Determination and discipline. If you want to achieve your weight loss goal in a limited time, you have to make up your mind that there will be no backsliding. Either you consistently do what it takes to get the weight off, or the weight stays on. You won't have time to catch up if you let yourself slip. Success will be your only reward.
You need to set targets or goals that you can measure so there's no guessing involved. Your target is not 'lose weight quick' but more like 'lose 50 pounds in 4 weeks by doing X and Y exercises and eating A, B, C foods consistently, no breaks allowed' (adjust for your needs). Lay out a daily plan with short-term targets that you can keep aiming for. If you start with 50 pounds in 4 weeks, you can spread it out over the 4 weeks so that you aim for 12½ pounds each week, or just under 2 pounds a day. Do the same for the food and exercise changes you will need.
What to Eat for Rapid Weight Loss
In your plan, you don't have to list out your menus for each meal every day, but you do have to make shopping lists with fruits and vegetables, high-fiber foods, and lean meat or fish, and only bring home those items, no exceptions. You need to plan on breakfast every day, since that speeds up your metabolism for the whole day. You'll also have to arrange for many small meals instead of a few big ones, to keep your blood sugar from spiking. And don't forget to drink a lot of water to fill up your stomach before meals and suppress your appetite.
