Not meaning to offend any doctors out there, but form my talks with a few doctors of my clients, they had no clue when I was talking to them about T3/T4 uptake, and many other metabolic processes that can be accelerated/manipulated by diet and supplements.
Granted, these were all family practice doctors, not endocinologosts, but still to say "diet boosters are bad" and not do full research makes me doubt the opinions given by those who are not specialists, or have a special interest in the field.
So, LOL, you can see that I don't have a doctor. LOL. I am looking for one in my area that is either a fitness-minded person, or has studied this sort of field.
ANYWAY, that's my little rant. I have a hard time taking exercise advice/diet advice from an overweight middle-aged man who is clearly not the picture of health (my last 3 doctors).
One actually told me to stop lifting weights! It went like this:
Doc: "So Dan, do you workout?"
Me: "Yes, I am a personal trainer, as it says on that form I had to fill out for you. I workout, yes."
Doc: "Hmmm ... Looking at your chart, it says you had a heart murmur when you were younger. Lifting weights may be bad for you."
Me: "What was that?"
Doc:"Yes. Lifting weights causes a great overexertion on your heart, and it may cause problems for you."
Me: "A murmur from when I was 16 will cause problems for me now?"
Dr: "It might, you never know. It may reoccur. To be safe, I would suggest you stop lifting weights."
Me: "Hmmm. How about running, can I run?"
Dr: "Just don't push yourself too hard."
Me: "Define that."
Dr: "Some light jogging is OK, but don't go too hard."
You can see where that goes ... LOL ... It got ugly, and I left. When I compete next year, I'm gonna send him a picture. When I break 300 pounds on my bench, I'm gonna send him a pic of that too.
SO, LOL, back to the questions ...
SLIM: I personally don't see how caffeine would make weight loss sluggish or cause weight gain. The 35g of sugar in each can of Coke, however, I can see how that will cause a fat gain.
Brianna: The answers are in Chapter 1. LOL. It covers it all, and then some.
Meg: Ephedra by itself gave only marginal results in studies. It is the combo of Ephedra and Caffeine that was the breakthrough. But, if you have health reasons for not taking caffeine, then I would say not to take it.
