My personal trainer referred me to https://www.amazon.ca/Fast-Metabolism-Diet-More-Weight/dp/0307986276
At it’s most basic:
No wheat, corn, dairy, soy, sugar, caffeine, alcohol, dried fruit or fruit juices, artificial sweeteners, fat-free “diet” foods
Diet confusion, cycling diet with a change in strategy every few days
Phase 1 –> high-glycemic, moderate-protein, low-fat = days 1 and 2
Phase 2 –> high-protein, high-vegetable, low-carbohydrate, low-fat = days 3 and 4
Phase 3 –> high healthy-fat, moderate-carbohydrate, moderate-protein, low-glycemic fruit = days 5, 6, and 7
The point of this diet to to keep the body from “thinking” it’s in starvation mode, get all metabolism organs functioning at high level and together, and create environment where food is used for energy and muscle growth, where fat is drawn from body and used for energy, burned off. This is not a calorie counting diet where calories in/out are focused upon. A calorie isn’t really a “thing” the way it’s often thought of as in diets. This diet has you actually eat more, the more weight (fat) you plan to loose.
I’ve seen mixed reviews on this, some people have shared their anecdotal experiences of actually losing a significant amount of weight
others have said that it’s pseudoscientific, based on a fad, and even harmful
I like my personal trainer as I have seen improvements in my strength training over a few weeks so far
and he recommended to me this diet to try for 28 days
is this diet legit though? and if not, why would my personal trainer recommend it to me? he seems knowledgeable about fitness , trains athletes, and has a background in kinesiology
for me, I have a science background as well, as i’ve taken courses in physiology, nutritional science (basic), biology, etc. and i think the explanations in this book have been relatively reasonable and sound? or maybe I’m overlooking some major flaws in the reasoning?
I don’t know more about it than what you have posted but my initial take is that it appears like a way of cycling the relative amount of carb intake with the goal being weight loss and potentially something that may be called ‘metabolic flexability’ ie the ability to use fat or carbs for fuel. I’m skeptical of low carb diets and super high protein diets but if you were wanting to go low carb for a while in order to lose weight (i know its not the only way) then this way of doing that wouldn’t be as bad as chronically going low carb. So i’m not sure of what the actual claims are that they make but the overall diet doesn’t seem to bad.
