Some people can't eat grapefruit because it interacts with certain medications. Others just don't care for it. Either way, don't substitute it with oranges or orange juice. Oranges won't give your body the same alkalizing effect that grapefruit produces. In fact, oranges promote more acidic pH balances. The more acidic the pH balance, the easier it is for the body to store fat.

The study authors believe that sleep deprivation can cause your body to produce extra hunger hormones (like ghrelin) and fewer satiety hormones (like leptin). This means you’ll feel hungrier and have a harder time controlling your cravings once they hit. Most adults should aim for at least 7 to 9 hours of shuteye per night, per the National Sleep Foundation’s recommendations.
One of the most important things to take into consideration when either trying to lose or put on weight is output versus input. It is important to know the amount of energy your body is using every day, so that your intake fits the needs of one's personal weight goal. Someone wanting to lose weight would want a smaller energy intake than what they put out. There is increasing research-based evidence that low-fat vegetarian diets consistently lead to healthy weight loss and management, a decrease in diabetic symptoms as well as improved cardiac health.
Diarrhea can also be due to a lack of fiber in the diet, says Kizer, which can happen when someone cuts way back on carbs (like whole-grain bread and pasta) and doesn’t supplement with other fiber-rich foods, like vegetables. It can also be caused by an intolerance to dairy or artificial sweeteners—things you might be eating more of since switching to a high-fat, low-carb lifestyle.
