Dear Lea

Dear Lea: My daughter and I are embarking on a 28-day Fast Metabolism Diet adventure for the first time. Have you heard of this? My goal is to refresh my metabolism and shift old habits. –CP.

Dear CP, I was not familiar with the Fast Metabolism diet per se (there are so many diets on the market), but I reviewed the diet today and have some comments. I agree with the many healthy diets that currently limit corn, soy, gluten (wheat), sugar and include lots of veggies, fruit,healthy fats, nuts, seeds and whole grains. This diet’s different approach, of course, is the alternating amounts of carbs, fats and protein every few days. Gluten and soy generally are hard to digest even if you do not test “intolerant”. Corn is a starchy food and so often GMO. Sugar is a concentrated form of carbs so is usually high calorie and high glycemic both of which aid weight gain.

To lose weight no matter what the approach portion sizes should be considered. This diet defines portion sizes reasonably well. Eating at least every 3-4 hours (with the 3 meals, 2 snacks) helps to keep your metabolism steady so you continue to burn calories. Calories in, calories out is not always the answer to weight loss anymore but moderation is always helpful.

By the way, I found a wonderful brand of stevia, Pyure. There is very little aftertaste! If you are a caffeine drinker, be careful about going “cold-turkey”. You may experience some headaches during the first few days.

After you complete the diet, I recommend continuing to eat healthy, unprocessed foods with the emphasis on lean protein, healthy fats, nuts, seeds, lots of veggies with low glycemic whole grains and fruits in moderate amounts. The trouble with diets is that people often diet then go back to the way they were eating that was unhealthy or originally caused the weight gain. The healthy snacks on our website will help with healthy between meal snacks.

Best of luck this month and congratulations on choosing to care for yourself by eating healthy!
