How to Find the Right Weight Loss Diet for YOU

No matter your size or shape, whether you want to lose weight or just get healthier, there’s a diet that’s just right for YOU!

It’s a new year and time for a new you, but how do you choose the right weight loss diet? Your friend lost weight and felt great on keto, while you just felt bloated and constipated. Your mom went vegan and took up yoga and feels the best she has in her life, but all you felt was tired and hungry – all the time. Your dad eats whatever he wants, hits the golf course every chance he gets so he can “walk it all off” and doesn’t gain an ounce.

If it seems like every diet you’ve tried has failed you, you’re far from alone. According to the American Journal of Clinical Nutrition, only 20 percent of people who go on a diet are able to maintain the weight they lose for the long term. Why do so many fail?

The main reason so many weight loss diets fail is because they simply aren’t the right tool for the job. If you’re looking to lose a quick 10 pounds for a special event, you don’t need the 200 page detailed plan for life. And if you’re looking to revamp your entire lifestyle, lose a large percentage of your body weight, and fight off chronic disease, you can’t do it all with a juice fast.

For any diet plan to work for you, it has to fit your goals and your lifestyle, and be flexible enough to change as you change. The science behind it should be sound – so say NO to fad diets. For a diet to become a lifestyle it has to stand the test of time.

Over the past 4 decades I’ve taken what I’ve learned from scientific research, ancient healing wisdom, and from listening to YOU, and have created plans you can tailor to fit your personal needs and goals. Whether your goal is to lose a quick 5 pounds, reduce inflammation through a cleanse, detox to have more energy, support your body during chronic illness, or to lose more than 50 pounds over a long term, there’s a plan that fits you just right.

Quick and Easy Weight Loss Diet and Detox Plans

Fat Flush Soup Diet

Lose up to 10 pounds per week with this easy one recipe, diet and detox in a bowl. This soup is one of the most copied recipes of all time, but unlike the copycats, my soup is based on scientific research, is clinically tested, and the recipe is updated each time new research comes to light. Use this soup for up to 2 weeks for quick weight loss, or as a jumpstart into the New Fat Flush Plan for more weight loss and detox, Fat Flush for Life if you are at your goal weight, or Radical Metabolism if you’re missing your gallbladder or need support for other health issues.

For the Long Term – New YOU, New Lifestyle

The New Fat Flush Plan

When you need a lifestyle makeover to get healthy, stay healthy, and achieve your weight loss goals, you need the New Fat Flush Plan. Whether you are looking to lose 5 pounds or more than 50, this bestselling plan has worked for countless people looking to get healthy and reach their goal weight – and stay there for life. This plan has been revised and upgraded from the original Fat Flush to include the 3-Day Tune-Up for faster cleansing and updated food choices that are Paleo, Keto and Vegan-friendly. This comprehensive plan has 3 main phases:

  • Phase One is a quick, 2-week detox. The goal is to detox your liver and colon to get ready to process and eliminate fat more quickly.
  • Phase Two is the metabolic reset for long-term weight loss, where you stay until you reach your goal weight.
  • Phase Three is the maintenance for a healthy life. This phase is full of foods that will keep you satisfied and makes it easy to maintain your new figure and healthy weight for your lifetime.

Your Body Knows Best

If you’re looking to learn how to really listen to what your body needs from the foods you eat, then add Your Body Knows Best to your reading list. Once you are on the maintenance phase of the Fat Flush Plan, you may be looking to fine tune your long-term lifestyle. This is where Your Body Knows Best shines. In this book I explain how your ancestry and blood type define which foods work best with your genetics, and how to determine your metabolic rate and what that means for your food choices.

    I am so tired and rather have energy to do a deepdivesinto a detailed plan like Radical Metabolim. Is there a “Radical Metabolism for Dummies and the penny puncher who does not alot of remaining money each month. I really need the help – I am newly turned 48!
