s/o to"If you just don't eat, will you eventually lose weight".

I always thought if you burn more than you eat, you lose weight...so why does your body go into "starvation mode"? If you take in 900 calories a day and yet burn 1500...how will you not lose weight? It seems contradictory to me.

Can a person lose weight if they change their diet, but not exercise?

  • It will also create other problems for you like lite headedness, dizziness, fatigure, low energy among other issues since the body needs enough calories to function.

  • I've always been told that you have to eat some fat (good fat) to burn fat.

  • It's true that calories in vs calories out will help you to lose weight, but if you aren't eating enough your body does hold onto every calorie it gets. You have to eat in order to lose weight.

  • Your brain requires a certain amount of glucose sugar to survive as do your organs. If they are not getting that in the diet, that's what "starvation" mode is - it stores all the glucose as fat for longer storage, and may start breaking down muscle to get the energy from the proteins.

  • yes, but if you drastically reduce your fat intake, or your calorie intake and your body has to start using it's storage to function, and in turn will start to hold onto those stores since it senses there's no new coming in, so it starts metabolizing it's own muscle instead.

  • Starvation is real. Not eating long enough will cause you to lose weight.

    Fasting for short periods, aka crash dieting, doesn't help women lose weight. Estrogen kicks in and tells the metabolism to slow way down and store fat. This is a biological fail safe to keep our body fat percentage high enough to support reproduction. This happens in most female mammals.

    This is why women who lose weight successfully have an eating plan that is more like all day snacking combined with a ton of activity. A low calorie diet works when you so ace the calories out all day long.

  • Because the human body must have fuel (calories) in order to function. It needs fuel for organs to function properly etc.. So the human body goes into what is called "Starvation mode".. That means the body knows that it is not going to be getting fuel (calories) for an extended period of time so it actually stores the calories that are consumed instead of burning them for energy so that the body's organs has fuel to function.

    This is damaging to the body in many ways and is a very unhealthy way to try and lose weight.

    In order to lose weight. The body must actually burn the calories off that it has taken in. The more calories that are burned, the better the body becomes at burning calories (ie: metabolism raises) and the body can actually consume more calories (within reasone) and still burn them off in a healthy manner through exercise producing weight loss.

  • yes, if you burn more than you eat, you do lose weight. BUT that burning of calories needs to be done with exercise and you still need to ingest the basic number of calories and vitamins every day.
    simply NOT eating isn't a good way to lose weight. "starvation mode" comes from the stomach being empty and sending messages to the brain, not with calorie burning.

  • Yes, but do it the smart way. Eating produce and lean protein will give you the nutrition your body needs to function properly and allow you to lose weight. Cut calories not nutrition. Contact me if you would like to know how you can improve your nutritional status and lose weight.
