How safe is to drink 2 gallons a water a day while on a low calorie diet?

Water intake: Not really safe. You need roughly 64 ounces of fluid a day. 2 gallons of water is 256 ounces of fluid, not only that, it is free water rather than balanced electrolytes. The net effect will be that you will eventually become hyponatremic and that can cause you all sorts of problems. You could probably do a gallon and still be okay. 2 is pushing it. ...Read more

Is it safe to eat a low calorie diet and exercise 3-4 hours a day?

Is it safe to eat a low calorie diet and exercise 3-4 hours a day?

How low is low?: Seems to me that exercising 4-5hr/d is a bit excessive. You only need 30min or so to improve your health. As for low calorie diet, it depends upon how low is low. More importantly, what kind of calories are you consuming? Healthy or junk? Processed or otherwise? What's your goal w/this extreme approach? Discuss your concerns, plans & goals w/your family doc who knows most about you & your health. ...Read more

No safe shortcuts: This type of diet often makes the body angry, decreasing calories too much too quickly will send your body into starvation mode. Less calories = weight loss, but your body will become more efficient at holding onto calories, so you will gain the weight back and then some later on. Weight watchers is the safest and most consistent in my experience with thousands of people. ...Read more

Is if safe for obese-kids to have very low calorie diet?

Is if safe for obese-kids to have very low calorie diet?

Not for young kids: Obese young children who are still growing in height can stay on a low (not extremely low) calorie balanced diet. They should lose enough weight to drop down from the "severely obese" BMI range, into the "obese" range. Then, they can take advantage of their height growth combined with moderate caloric restriction, to gradually drop into the "normal" BMI range over a 1-2 year period. Exercise too! ...Read more

In : In general, slow transitions work best. Gained weight comes from consuming more calories than you burn. Some people burn more calories than others at a baseline (normal activity), others gain weight very easily - this baseline of calories burned will slowly decrease through almost everyone's lifetime. As you increase your calories, monitor your weight and note the time you commit to exercise each day or week. If you start gaining, either increase your exercise intensity or eat healthier foods with less fat and sugar. Not all exercise is equal, shorter durations of high intensity exercise is much better than a leisurely walk or sitting on a stationary bike and reading a book, however any degree of exercise is better than nothing.

Yes, it helps some: Salads are good fillers for stomach, so that you can avoid other calorie rich foods. But salads are only helpful if you avoid regular dressings which are loaded with fat. So use vinegar of leman on your dressing. Salad is recommended daily and even 2 times day is better.. Add some fruits fruits also with each meal. ...Read more
