Meal prep, short for meal preparation, is the process of planning and preparing your meals ahead of time. You can meal prep one day ahead, or take one day to prepare lunch and/or dinner for an entire week. While most meal prep only one or two meals, you can easily meal prep breakfast, lunch and dinner, even snacks for the week ahead. It’s entirely up to you!

Real talk: It could take weeks or months to see the metabolic effects of exercise on the scale, and even then, building muscle, which is denser than body fat, could lead to weight gain. "Do what you like because it’s good for you," Dr. Seltzer says, noting the way exercise is awesome for your heart, mental health, and more—and that not all measure of progress can be seen on the scale.
During the 3 days of the diet, balanced nutrition is lacking. Some of the foods that are recommended are high in salt and fat and would not be appropriate for people with certain medical problems like heart disease, high blood pressure, diabetes, or high cholesterol. You may not be getting enough vitamins, minerals, and fiber while you are on the diet. If you are taking medicine for your diabetes and want to try the 3-day diet, it's important to talk with your doctor first about how to adjust your medicine.
First things first – planning. Before you start to prep your meals, you need a nice, solid plan. Coming up with a meal plan may sound overwhelming at first, but it’s not as bad as it may seem. Just take it one step at a time and start with one, simple meal you love and that you know is healthy, and then work your way up. Soon, you’ll be prepping all your meals! Watch out – it gets addicting!
Becky–this is a great quick start plan. I want to lose 5 pounds I put on after a recent weight loss. It’s very balanced with lots of plant protein as well as animal protein. My only comment is that it’s a lot of fiber very quickly, and I know that this would cause me intestinal pain, especially from raw veggies. It’s so advantageous to have these available by prepping, so I will eat smaller portions (1cup carrots is too much for me at 120 lbs), chew them well and eat slowly and save the rest in case I am still hungry before the next meal! For people who are used to eating more food, I’m wondering if they are able to handle the fiber better than someone like me who has already learned to cut way back on portion sizes!
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
Portion control is a big part of losing weight and keeping it off, according to the Mayo Clinic. Pre-packing your lunch could help. “Learn about portions and embrace the idea, not just because they help you lose weight, but because it’s great to know the right size for your own body and activity level,” Dr. Bazilian says. Portioning out your lunches also takes the guesswork out of eating out and could help you save money. These are the tips a weight loss coach won’t tell you. 

Similar to the CICO diet, the Body Reset has gained popularity via social media, and there isn’t any definitive research that suggests the approach is safe and effective. Celebrity trainer Harley Pasternak created the plan, which is essentially a three-phase liquid diet comprised of smoothies and moderate exercise. While U.S. News notes you may lose weight on the diet, it may be tough to stick with, and isn’t safe for people with diabetes and heart disease. (38)
Knowing what you're going to eat for dinner may help prevent those last-minute stops at the fast-food restaurant. Spend a little time once a week planning out your dinner menu and prepping ahead, such as defrosting your chicken and chopping veggies. Make a healthy chicken Parmesan by topping a 3-ounce grilled chicken breast with 1/2 cup of tomato sauce and 1 ounce of low-fat mozzarella cheese, and serve it with 1/2 cup of cooked whole-wheat spaghetti and 2 cups of steamed broccoli. This meal has 425 calories.

When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
Fiola Sowemimo, MD, board-certified in internal and bariatric medicine, says that the quality and quantity of food you eat is only half of the weight loss equation. “Regardless of which diet you choose, when you eat is important too,” Dr. Sowemimo says. Starving during the day and ignoring hunger could lead to bingeing later, she says. Plus, Wendy Bazilian, DrPH, RD, adds that the peaks and valleys of hunger throughout the day could make it more difficult to manage cravings. Eating regular meals at regular times could actually help normalize your metabolism, according to Dr. Bazilian.  

Keep in mind that the first time that you sit down and plan meals to lose weight the process will take a little longer. But once you have a system in place, you'll breeze through the ritual—you might even start to enjoy it. Getting organized feels good and reaching your weight loss goals feels even better. So take enough time to follow through with the prep steps to get used to your diet plan and stay on track. 

Here’s the full shopping list for exactly what to buy, and check to make sure you have a few pantry staples on hand. Morris recommends starting on a weekend, so you can make a big pot of veggie soup, and give your body a chance to adjust before diving into a busy week. Her plan cuts carbs for the first couple of days, before slowly reintroducing whole grains. And if you want to mix it up, there are lots more options for healthy snacks, just make sure to get a serving of fruit or vegetables, along with protein.
