Cutting calories to help reach your fat loss and weight loss goals is not as easy as “just doing the math.” You need a healthy meal plan to start the process. After that, you will make many adjustments until you know how different foods affect your body.
And don’t think you can just eat 1,000 calories every day and continue to lose weight (because you have a caloric deficit). This tactic will only work for a short time. Your body doesn’t know you’re on some crazy diet. It thinks you are starving, so it goes into survival mode and stores body fat. Many of you have wrecked your metabolisms by eating too few calories during the day (month after month).
First, don't think you will have it all figured out in two weeks' time! Experts agree that you are better off making manageable changes to your diet and workout routine. Some of your eating and workout (or no workouts) habits have been developed over a lifetime.
For example, severely limiting sugars from your diet would be a great start. Drink water instead of sodas and sugary drinks. Just this one change will slash tons of calories every day. And, you will be on your way to burning dangerous belly fat.
For instance, my basal metabolic rate (how many calories my body would burn if I did nothing all day) is about 2,000 calories. If I eat 2,000 calories and burn 500 calories through exercise and daily activity, I will still lose weight and burn fat (500 caloric deficit).
If I starve myself and eat 1,200 calories (1,300 caloric deficit) day after day, my body will rebel and store body fat. A 1,300 caloric deficit is too large (severe calorie restriction).
You will find it easier to cut more calories by eating healthy and eating foods with high water content. You will actually be eating more while eating fewer calories. And, you will feel fuller for a longer period (thereby eating less).
Energy density of food is a key component when trying to add volume to your diet. Energy density (ED) is defined as the amount of calories of a food divided by its weight in grams.
You would basically focus on foods rich in fiber with high water content (or low ED value).
