Should you eat only 1000 calories per day and exercise 3 times week to lose weight?

That is not a safe calorie consumption for anyone, especially someone starting an exercise program. Know this, it takes consuming an extra 3500 calories in a week to gain one pound. Likewise, you must burn or cut out an extra 3500 calories in a week to lose one pound. Do the math to figure out your weight loss. It is safe to only lose 1 to 2 pounds per week so don't plan on more. If you lose more, you'll just gain it back and you could get sick. Think one pound is nothing? How about this, one pound is equal to 4 sticks of butter. One pound is something! Take a multivitamin when exercising and dieting. Drink a lot of water, 8 glasses a day. Don't be afraid of calories, arm yourself with information. Keep a log of how many calories and foods you consume. Get your sugars from fruit, not sweets like cake and candy. Eat carbs in moderation, as small side dish portions with your meals not a whole meal of white rice or pasta.
