Many diet plans cut out entire food groups, which can create nutrient deficiencies as well as health problems. For instance, if the diet is very low in carbohydrates and you have type 1 diabetes or type 2 diabetes, it’s probably not a good fit. And if it’s too restrictive and you’re pregnant or breastfeeding, it’s not a good idea, either. Keep in mind that pregnancy is not a time for weight loss. Speak with your doctor before making any changes to your diet if you are pregnant or breast-feeding.
If you want to lose weight, you’d better avoid special “low-carb” products that are full of carbs. This should be obvious, but creative marketers are doing all they can to fool you (and get your money). They will tell you that you can eat cookies, pasta, ice cream, bread and plenty of chocolate on a low-carb diet, as long as you buy their brand. They’re full of carbohydrates. Don’t be fooled.
Some women have trouble losing weight because of a hormonal problem. The thyroid gland, located in the neck, pumps out hormones that control body metabolism. If the gland's output isn't high enough, a condition known as hypothyroidism, the pounds can pile on - and stay on. If you think thyroid trouble might underlie your weight-loss difficulties, a doctor can test your hormone levels via a simple blood test. If you have a deficiency, effective treatment is available.
It is best to eat a strict Bulletproof Diet for at least a week or two beforehand to store extra nutrients. This also helps reset your hormonal status if you’ve been yo-yo dieting. You don’t have to do this, but it’s a good idea. You may find that eating The Bulletproof Diet is enough of a stimulus for weight loss, and that fasting is unnecessary. You also need to get used to digesting fat if you’ve been on a low-fat diet.

If you want to lose body fat, going low carb – or even ketogenic – can help you program your body to burn fat for its main fuel. By reducing calorie consumption after becoming fat-adapted, you can focus on fueling with fibrous vegetables and protein, reduce fat intake, and your body will use stored body fat for energy. With consistency and dedication, this can result in rapid fat loss.
Spreading the same amount of calories out over the course of your day so that you’re eating within an hour of waking up and then every four to six hours will jumpstart your metabolism, kicking off your calorie burn, and keep it going at a steady pace all day long, Crandall says. This works for a lot of people by keeping blood sugar levels steady, preventing the surges and plunges that can lead to ravenous hunger and overeating. It also keeps you from feeling deprived.

Are you like Old Faithful when it comes to your morning walk or evening jog? Know this: The more you do an activity, the more your body adapts to it, so you burn fewer calories. If you want to light a fire under your metabolism, consider cross-training. For example, if you normally walk, try biking instead. "Since you're not used to working all those different muscles, it's a more intense workout, which can translate into a greater metabolic after-burn because your body is working harder to recover and get oxygen to all your tissues," says Carol Espel, M.S., an exercise physiologist for Equinox Fitness Clubs in New York City.


Sugary treats, while obviously delicious, aren’t very good for our bodies—and that includes our tummies. Not only do the added calories add inches to our waistlines, but sugar overload leads to insulin resistance, which tells the body to store extra fat around the waist. But that’s long-term stuff. Sugar also bloats your tummy in the short-term by feeding the bad bacteria in your gut, leading to extra gas. When it comes to flattening your belly, nixing sugar is one of the best things you can do including these 42 other easy tips to lose weight fast!
