Once you’re done with your meal prep, make sure you let your meals cool down before transferring them to airtight containers and storing them in the fridge, but make sure you don’t keep your food in room temperature for more than two hours. If you are using meal prep containers and have stored your cooked meal prep well, it can last in the fridge for up to 7 days.  Some foods will keep longer than others, which is something to consider when prepping 7 days at a time.
We often make the wrong trade-offs. Many of us make the mistake of swapping fat for the empty calories of sugar and refined carbohydrates. Instead of eating whole-fat yoghurt, for example, we eat low- or no-fat versions that are packed with sugar to make up for the loss of taste. Or we swap our fatty breakfast bacon for a muffin or donut that causes rapid spikes in blood sugar.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG diet is not safe for anyone, the Mayo Clinic notes. (35)
If the diet is a quick fix rather than one that promotes lasting lifestyle changes, this could pose a problem. In particular, extreme diets that promise big weight loss up front aren’t always sustainable — and you may end up overeating or even binge eating if you feel deprived. “Consider if the diet’s habits are ones you can continue throughout your lifetime, not just 21 or 30 days,” says Angie Asche, RD, a sports dietitian in Lincoln, Nebraska.

High blood sugar levels coupled with high blood ketones, on the other hand, will mean that you have a pathologically low level of insulin – something non-diabetics do not suffer from. This can lead to ketoacidosis – a potentially life-threatening condition. If this happens, you’ll need to inject more insulin; if you’re at all unsure of what to do, contact a medical professional. Coveting really high blood ketones for weight control is not worth the risk for type 1 diabetics.


Meal prep is a simple and easy way to track your food intake. Whether you just want to stay away from over-processed foods and eat healthy to build muscle, lose weight, or simply feel better, meal prep is a great idea. Prepping all, or at least most your meals, ahead of time makes cooking and eating healthy, nutritious food easier and quicker than ordering take out or grabbing some fast food on the go.
While there are probably plenty of pre-made bean and veggie soup options that just need a few minutes to heat through on the stovetop, making your own soup is really easy—and a great idea for your health. Homemade soups are much lower in sodium – about 100 milligrams or less per 2-cup serving. By contrast, 2 cups of many canned soups contain a blood-pressure-busting 1,200 milligrams or more, a worrisome amount considering that health experts recommend consuming no more than 1,500 milligrams of sodium for the entire day. This is also a great way to use up all those leftover vegetables in your crisper—pretty much anything works in this soup.
This plan was developed by nutritionist Dawn Jackson Blatner, RD, to allow vegetarians to have a burger every once in awhile. There is no specific weight-loss claim, but the guidelines recommend around 1,500 calories per day, so there’s a good chance you’ll lose weight. Recipes are available online and in Blatner’s book. Vegetarian diets have been linked with reduced risk for diseases such as diabetes and heart troubles, but you have to make smart food choices to avoid nutrient deficiencies. Learn about the healthy diet plan nutritionists recommend for weight loss.
Because the diet isn’t as restrictive as a traditional vegan or vegetarian diet, it may be simpler to stick with — hence its No. 2 ranking in U.S. News & World Report’s Easiest Diets to Follow category. Because you’ll be eating meat some of the time, you may also be at a lower risk of the aforementioned nutrient deficiencies that vegetarians and vegans may face.
There are many ways to do intermittent fasting — ranging from fasting for a number of hours each day up to an entire 24-hour fasting period one or two times a week. “If you're trying to kick a habit like eating late into the night, then stopping eating earlier in the evening and fasting overnight could be beneficial for you,” says Hultin. “There are many types of intermittent fasting, so ensuring you pick one that works for you and your lifestyle is important.”
“There are many diet plans on the market today that promote good health,” says Emily Kyle, RDN, who is in private practice in Rochester, New York. “The key is finding one that does not cause you stress or agony.” Ask yourself questions such as: Would the diet guidelines make you happy? Anxious? Stressed? Are you able to follow them long term? “Factors such as enjoyment, flexibility, and longevity should be strongly considered,” adds Kyle.
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
Ready to step it up with your Fitbit tracker and set some new health and fitness goals? That’s awesome! Cue the fireworks! But if your ultimate goal is to lose weight, unfortunately, activity alone isn’t going to get you there—you also have to change what you eat. That does not mean you need to do a cleanse or detox. But it is possible to get a jump on weight loss, the smart and healthy way. Fitbit Dietitian Tracy Morris developed this kickstart one-week meal plan to help her clients see results, fast. Disclaimers: Please don’t try to lose more than 2 pounds per week, or dip below 1200 calories per day, which can compromise your metabolism. This is not a long-term plan, so you definitely don’t want to eat this way every week. But it’s a great way to kick off a weight loss goal, with specific meal and snack ideas, so you’ll see an initial drop—and be extra motivated to keep the momentum going this year. Increase your drive to succeed, and see how many consecutive days your can stay on track, by using Fitbit’s food logging feature.
