Many people who try to lose weight, including myself, will basically starve themselves to lose weight or eat next to nothing.
I'll tell you through personal experience and research that it does work in theory. When you starve yourself your body will use body fat for energy, therefore making you lose weight. However, with this fat loss comes muscle loss. Muscle is one thing that is responsible for your resting metabolic rate ( or your metabolism). So when you starve yourself and you lose muscle you will naturally burn less calories each day than you did before you began to starve yourself. Therefore if, and when, you fall off starving yourself and begin eating like you used to, you will gain even more body fat than you had before you started.
Another reason why starving yourself should never be an option is because your body needs calories and nutrients to protect itself from sickness. So, if you eat next to nothing I promise that you will end up getting sick because your immune system will be down.
Starving yourself works to lose body fat but you can't do it for the rest of your life - it’s a fact, and doing it for an extended period of time will only make you sick and most likely result in more body fat than you had before.
Don’t try to beat this by only doing it for a short period of time either - the adverse side effects are there and they will catch up with you. Starving yourself will make you tired, groggy, sick, irritable, and even depressed.
Take my advice and find out how many calories you need a day to maintain your weight- you can do this by reading my post a couple days ago. Subtract 500 calories from that number and do a little exercise and lose 1-2 lbs of pure fat a week. Losing weight isn’t worth endangering your health. Here's one on-line calculator I found that you can try.
Tony's Tip: Write down what you eat every day for 1 week and see if you can guess how many calories you consume per week. Then calculate it out and see how close to correct you were.
