Is Fasting Safe For Losing Large Amounts Of Weight
Not safe: Your body needs calories, nutrients, water to survive. A simple liquid fast of water, juice could be o-k for 24 hours, but it certainly is not a method to lose "lots of weight". Please also consider the role model you may set for your family members. You selecting proper eating habits will help your family do the same. ...Read moreSee 1 more doctor answer
My friend (morbidly obese) wants to try lean gains (intermittent fasting) to lose weight. I am concerned for her. Is this safe or even healthy?
Fasting: Fasting is never a good way to lose weight. It generally slows your metabolism and contributes to the yo-yo effect of losing weight and regaining it back plus more. There really isn't anything healthy about fasting. Conversely, eating multiple (3-5) meals (healthy & small portions) is better for your metabolism and weight loss (but you have to exercise too). ...Read moreSee 2 more doctor answers

Is it safe to lose weight by not eating if i take multi-vitamins? I am trying to lose weight. If i only don't eat, or only eat one meal a day, will i lose weight and still be healthy? Some people say i won't get enough nutrients, so I am taking multi-vita
It : It is not likely that you will have sustained weight loss just from fasting. This is because your body will interpret this as starvation and will "hold on for dear life" to the fat in your body to keep you going. Vitamins are not enough nutrition to prevent this problem. Eating only once a day probably also will not be effective. I have heard that sumo wrestlers actually make themselves gain weight by eating only twice a day, getting hungry between meals. What happens specifically with eating very little (one of the ways the body adapts to calorie restriction) is that your thyroid metabolism changes, so that the T4 made by your thyroid gland converts to reverse T3 (liothyronine) instead of the active T3 (liothyronine) that your body needs to function. This is nature's way of protecting us from starvation. Anything your body interprets as "physiologic stress" will cause this phenomenon, including dieting, depression or illness. This is why an effective diet program must include enough total calories and balanced nutrition (complex carbohydrates, protein and fat) to give your body what it needs while inducing a fat-burning state. ...Read moreSee 1 more doctor answer
Probably not: To maintain health, it is important to nourish your body with healthy foods.

Losing weight requires lifestyle modifications whereas fasting is a state of deprivation. ...Read more
This is NG: Eat foods that are nutrient dense (like meat, fish, poultry, eggs, cheese, low starch vegatables and water) avoid foods that are not nutrient dense (like starches and sugars, including fruit) nutrient dense foods will increase your basal metabolic rate. On the other hand, starches and sugars impair thyroid metabolism via affects on your liver (which helps activate thyroid hormone). ...Read more
Restrict salt use: Instead of fasting I would recommend restricting your salt intake to reduce water weight. Actually when people have a high blood pressure. The first course of act that a physician takes is to prescribe a diet with less salt. The western diet is extremely high in salt content. I would recommend only taking in a max of 1500 mg of salt. Salt is also called sodium. You can check sodium on labels ...Read more
No: Skipping meals sends an alarm message to your brain that you are under stress. These stress hormones cause your body to try and decrease energy use (decrease your metabolism) and to hold onto your fat. Eating 3 healthy small meals and 2 to three healthy small snacks through out the day is best. This supplies your body with the full it needs and keeps your blood sugar stable. ...Read moreSee 1 more doctor answer
Hazardous, temporary: Perhaps in the past water fasting was healthy. These days it is dangerous as we live in a toxic world & all have hundreds of toxins in our fat. When doing a water fast we burn fat & the toxins are released into our blood but our body has zero of the water-soluble vitamins (Vit. C, most B's) & phytonutrients essential to support our detox mechanisms, so it can make us quite ill. See comment: ...Read more
