This meal replacement plan has mixed scientific evidence to support it. SlimFast promises a reasonable one- to two-pound loss per week, but you’ll need to buy its shakes, bars, and other products. The 1,200-calorie plan allows for one 500 calorie meal of regular food daily, with the rest of the calories made up of SlimFast products, fruits, and vegetables. The hard part will be sticking with the program; also, the SlimFast foods contain a lot of processed ingredients and artificial sweeteners. This isn’t for people younger than 18, or pregnant or breastfeeding women without medical supervision. Make the most of your one meal with 11 simple swaps that lead to dramatic weight loss.
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!
Prep foods in advance. To make sure you stick to your diet plan, organize your meals in advance. You can do this after dinner in the evening. Lay out the foods you'll eat for breakfast so they are ready to go when you wake up. Then pack your lunch and snacks for the next day. Finally, do any meal prep for the next night's healthy dinner so that it's easy to throw together when you come home from work.

The best diet for losing weight is one that is good for all parts of your body, from your brain to your toes, and not just for your waistline. It is also one you can live with for a long time. In other words, a diet that offers plenty of good tasting and healthy choices, banishes few foods, and doesn't require an extensive and expensive list of groceries or supplements.
Consuming protein in the morning will stabilize blood sugar, Sharon Collison, RD, sports dietitian and clinical instructor at the University of Delaware says. “Make sure to have an excellent source of protein with every breakfast such as Greek yogurt, cottage cheese, or two to three eggs,” she says. Eating more protein earlier in the day could also help reduce sugar cravings in the late afternoon, Collison adds.
Your 28 days are up; you look great and want to keep it that way. Juge has an easy plan to maintain your body, yet enjoy greater flexibility with your diet. No.1, he says, is to eat a good, clean breakfast. If you're at home, it's much easier to do—just scramble a few egg whites and have a whole-grain item (whole-wheat bread or a bagel, for instance), and/or some fruit. Eat dinner at home, again a healthy, clean meal consisting of a lean protein source, green vegetable, and whole grains. Then, bring a protein shake or bar with you to work for a midday meal. "You've now got three clean meals taken care of," says Juge. So if you're eating at a restaurant at lunch and you want to have something different, you can have it. Just keep the rest of your meals pretty strict, without added sugars and fats.
Meal prep is one of the best ways to ensure you’re eating healthy all day long and prevent the vicious cycle of skipping meals during the day and binging on unhealthy foods once you’re finally home in the evening, one of the problems many people who are struggling with losing weight are facing with every day.  Plus, it’s so much easier to grab and eat food you’ve already prepared than to struggle with also cooking and/or prepping it when you’re hungry.
You will likely lose weight on any diet if you eat less than 910 calories a day. But losing 10 pounds in 3 days is both unlikely and unhealthy. To lose just 1 pound of body fat, you need to reduce your daily calories by about 500 a day for a whole week. That’s giving up 3,500 calories over the course of 7 days. To lose 10 pounds in 3 days would mean decreasing your calorie intake by 35,000 calories in just 3 days! The Academy of Nutrition and Dietetics recommends a slow and steady weight loss of no more than 1/2 to 1 pound a week. Otherwise you are losing muscle and water, as well as weakening your bones. You also are much more likely to gain it all back.
Lastly, consider how the diet plan can be incorporated into your lifestyle and whether it’s sustainable for you over the long-term. Most weight loss fails because of the dieter’s inability to maintain their commitment. Price, time requirements for meal planning and preparation, satisfaction and flexibility with your lifestyle are therefore essential to your success, no matter which diet plan you choose.

Ah, quinoa. This healthy, rich-tasting whole grain/seed has so many nutritional riches that it puts refined grains like white rice to shame. Tofu is the perfect sidekick because it’s both waistline-friendly (per bite, tofu tends to have about one-third the calories of meat and poultry) and heart-friendly (tofu has no artery-damaging saturated fat or cholesterol).

By planning your meals and logging what you eat and drink, you will start memorizing how many calories are in your favorite meals and ingredients. Best of all you will learn your own eating habits and cravings, so over time you can better plan your meals to suit your cravings. After a couple weeks if you see you consistently have a 3:00 pm craving for carbs, you can head off that craving in advance with a skinny sandwich at lunch. Or, a sweet craving at 10:00 am can be managed with a sweet oatmeal breakfast.
This could be because the body increases insulin secretion in anticipation that sugar will appear in the blood. When this doesn’t happen, blood sugar drops and hunger increases. Whether this chain of events regularly takes place is somewhat unclear. Something odd happened when I tested Pepsi Max though, and there are well-designed studies showing increased insulin when using artificial sweeteners.
If you want to lose weight you should start by avoiding sugar and starch (like bread, pasta and potatoes). This is an old idea: For 150 years or more there have been a huge number of weight-loss diets based on eating fewer carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
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!
