How to Do the 20/20 Diet

Preparing to Start the 20/20 Diet

Talk to your physician. Before starting any diet, even the 20/20 diet, consider talking to your doctor first. They will be able to provide with you guidance on whether or not this program is appropriate for you. Start by talking to your doctor about your desire to lose weight by following the 20/20 diet. Bring in the book, recipes and allowed food lists so your doctor can familiarize himself with this eating plan. In general, the 20/20 diet can be viewed as a well-balanced diet; however, the initial phase (which is short in length) is fairly restrictive. Talk to your doctor specifically about this phase of the diet and whether he thinks it'd be safe for you. Ask your doctor whether or not he has additional guidance, advice or resources on safe and healthy weight loss for you.

Write out your meal plan and grocery list. Like many diets, the 20/20 diet is fairly specific — especially in the initial phases. To help make your transition to this diet a little easier, write out your meal plan and a corresponding grocery list. Start by reviewing the allowed foods for whatever phase you're following. Also review the corresponding recipes that incorporate these allowed foods. To make your meal plan, take a calendar or date book and write in what you plan to eat for breakfast, lunch, dinner and any planned snacks. Do this for one week at a time. Review your meal plan and recipes and write up a corresponding grocery list. This will help keep you on track in the grocery store and prevent you from purchasing things you don't need.

Set up your exercise schedule. In addition to following a specific eating plan in the 20/20 diet, Dr. Phil also suggests setting up an exercise schedule. He gives some specifics in the diet to help support your weight loss. The first thing to do is to get clearance from your doctor. The diet recommends this and it's a general safety practice you should always follow. You need to make sure exercise is safe and appropriate for you. Consider joining an exercise program at a gym, working with a personal trainer, buy some fitness DVDs or watch them for free online, or just start walking for 30 minutes every day. As you become more familiar with which exercises you enjoy, try to write out an exercise schedule for yourself week by week (you can ask a trainer to help you with this, too). It should be similar to your meal plan. Write out what type of exercise you want to do and for how long on each day of the week. In phase one, it's recommended to start by increasing your steps and overall endurance. This is especially important if you haven't been overly active previously. However, if you're already in fairly good shape, Dr. Phil recommends that you start the 30 second exercise plan, which is detailed in his book. This is where you do 30 second bursts of very high-intensity activity alternating with lower intensity exercises.

Consider downloading the 20/20 app. In addition to the 20/20 book, there is also an app that you can download to your smartphone or tablet. This is an extra resource that may prove to be useful as well. The 20/20 app is available for both iPhone and Android devices. It's free to install with both. The app provides a lot of the same information as the book; however, the sources are less robust as is the overall content. You can find information on each of the phases, lists of allowed foods and a variety of recipes on the app. The app also has information on performing the recommended exercises.

Following the 20/20 Diet Phases

Start weight loss with phase one. To start off your weight loss on the 20/20 diet, you'll begin by entering phase one or the "five day boost" phase. The goal here is to help kick start your weight loss. The five day boost phase is the most restrictive part of the 20/20 diet. There is only a small list of foods that are allowed at this time. All are whole foods which are not processed and are naturally lower in carbohydrates. Start by gathering the list of foods that are allowed during this phase. They include: coconut oil, green tea, mustard, olive oil, almonds, apples, chickpeas, dried plums, prunes, leafy greens, lentils, peanut butter, pistachios, raisins, yogurt, eggs, cod, rye, tofu and whey powder. During this kick start phase, you'll need to eat four meals a day about four hours apart. Writing yourself a meal plan will help you stick to this schedule. If you purchase the 20/20 diet book, there are recipes provided for this specific phase.

Add in new foods with phase two. After you move through the five days of the boost phase, you'll enter phase two which is called the "five day sustain" phase. You'll continue your weight loss, but are now able to eat a wider variety of foods. In phase two, there are additional foods that you can eat; however, you need to continue with your current eating plan. Aim to have four meals a day about four hours apart. In addition to the approved 20 foods, you can also add: chicken breast, tuna, oats, brown rice, carrots, tomatoes, mushrooms, cashews, and blueberries. At each meal, you can add some of these new foods, however you still need to include two of the original 20 approved foods. This helps continue your weight loss. Another addition that you can do during this second phase is to incorporate two "sensible splurges" each week. These splurges need to be calorie controlled and total no more than 100 calories per splurge.

Continue weight loss with phase three. Phase three or the 20 day attain phase is very similar to phase two. You do get to add in more foods and your main goal is to work towards attaining your goal weight. In this last weight loss phase of the 20/20 diet, you are able to add in even more foods. These include: avocado, raspberries, mushrooms, potatoes, spinach, quinoa, and black beans. They include more carbohydrate rich foods, but are still very nutritious and low in calories. Again, the eating plan doesn't change. You're to aim for four meals about four hours apart and can still include the two "sensible splurges" for 100 calories each.

Assess whether or not you need to lose more weight. After the first three phases, you probably will have lost a significant amount of weight; however, to decide whether or not you should transition to maintenance, decide whether you want to continue with further weight loss. The 20/20 diet recommends that you evaluate your weight after phase three comes to an end. Do you still want to lose more weight? Or are you content with your current weight loss? If you'd like to lose more weight, it's recommended that you restart from phase one and go through all three phases again. Repeat this sequence until you've hit your desired goal weight. If you're content with your weight loss, you can transition to phase four which focuses mostly on weight maintenance.

Start weight maintenance with phase four. The last and final phase of the 20/20 diet is the maintenance phase. This is the final phase and the habits and eating patterns you've adopted shouldn't change. In order to prevent you from regaining the weight, the 20/20 diet recommends that you stay in phase three (with the occasional sensible splurge) long-term. You're encouraged to continue trying new recipes and monitoring your diet so that you stay on track with the four meals daily about four hours apart. Another important phase of maintenance is the continued work on your relationship with food and managing your desires to eat.

Maintaining Your Weight After the 20/20 Diet

Continue with regular exercise. When you've hit your goal weight after following the 20/20 diet, there are many lifestyle habits that you'll need to continue in order to maintain that weight. One of the is regular and consistent physical activity. Research shows that one of the best ways to maintain a healthy weight or a weight loss is by including regular physical activity. The 20/20 diet in addition to most health professionals will recommend that you include at least 150 minutes of cardiovascular activity each week. Also include one to two days of strength training in addition to your cardio. For cardio, you can try: the 20/20 diet's high-intensity interval training program, running, walking, using the elliptical, hiking, dancing or taking a spin class. For resistance training, try: lifting weights or taking a yoga or pilates class.

Moderate your "splurges and cheats." One place that many dieters slip up, is when they increase how much they snack or cheat during their maintenance phase. Too much of this behavior can cause weight regain. The 20/20 diet specifically emphasizes that you should monitor your splurges and cheats. It allows you two sensible splurges long-term, so use those wisely and make sure you stay accountable to those two splurges. You may want to keep a food journal or diary during your maintenance phase. This can help you plan for and remember splurges so that you don't overdo it. If you do notice some weight regain, one of the first places you should evaluate is the amount of splurges you've been having.

Review the 20/20 diet's guidelines about emotional eating. One unique aspect of the 20/20 diet is the emphasis on emotional eating and your relationship with food. It suggests continually monitoring this relationship and to work on controlling your cravings and desires to eat when you're feeling upset. The 20/20 diet says that your emotions play a big part in how much you eat and what you choose to eat. You need to continue to be aware of this so you don't fall back into old habits. The book associated with this particular diet gives a lot of great advice and tips on how to continually manage this aspect of your weight loss. For example, if you have a craving for junk food, try drinking a glass of water and going on a walk to help distract you from the craving. Or you could brush your teeth, which might keep you from indulging (and help support your oral health!).

Weigh yourself regularly. In addition to regular exercise and sticking to a sensible eating plan long-term, it's also recommended that you weigh yourself regularly and to track your weight long-term. The 20/20 book and many health professionals note that when you weigh in regularly and keep track of your weight, you're more likely to continue losing weight and have a much better time maintaining your weight loss. Try to get on the scale one time per week, long-term. Weighing daily isn't necessary since day to day fluctuations in weight are common and don't necessarily reflect an accurate overall trend. If you notice your weight creeping up over time, revisit your exercise schedule and food journal to see what's causing your weight gain. You'll need to adjust what you're eating so your weight starts to go back down.
