I know this isn't anything new, but after reading a few highly publicized articles about how diet is useless for weight loss, it seems that many people honestly believe this. I've even seen doctors and researchers agree. We certainly can't refute that nutrition plays an important goal in any body composition goals. Every individual responds differently to exercise too. Some people can start exercising three days a week for thirty minutes per session and the weight comes off. Others have to do considerably more with diet changes to see the same progress.
All these points aside, all of these articles completely ignore the muscle preservation effect of strength training. I'm sure there are plenty examples out there, but I was recently reading a study where diabetics either had a diet only and exercise + diet intervention. Both groups lost similar amounts of weight (as a result of an attempt to keep Calories equal, exercise group ate slightly more), but the exercise group gained ~0.5kg of lean mass, while the diet only group lost ~0.4kg of lean mass. This was with moderate weight loss (~2.2kg), over a short period of time (6 months). With a more aggressive intervention, I'm sure we'd still see quite a bit of muscle preservation, but considerably more loss for the diet only group.
To someone on the outside, it looks like the results were the same. However, the exercise group actually lost about 41% more fat mass. I don't know about all of these people spreading this bull****, but that sounds pretty good to me. I think that the lean mass preservation effects of exercise are overshadowed by the fact that there are so many other benefits outside of body composition. If any of these morons spent a day in a rehabilitation hospital, they would understand all of these other benefits. When you see a stroke patient, or someone who has just had a CABG, you are reminded of the health benefits of exercise. I understand that these people are just trying to get press, or flex their contrarian muscles, but there are really a lot of people out there that NEED exercise. Adding 3-30 minutes sessions of strength training per week to a diet would not do anything but improve results.
This post is really nothing more than a rant, but I can't stand to read one more article about how exercise is useless for weight loss.

When you change the study to look at fat loss, it is clear to see the flaws in the study. I think that is why most fitness professionals don't focus on weight as much as body composition. As an industry we need to stop using terms like "weight loss". Fitness professionals need to use body composition and leave "weight loss" up to nutritionist and dietitians.

As I mentioned, this was not a very aggressive intervention. The subjects were diabetics and the study looked at a variety of other variables including HbA1c, average glucose concentrations, etc.
I think the point of my post is being missed. Strength training is clearly important for health. However, exercise as a whole really doesn't get any credit when it comes to body composition goals.

I hear you 148%, SFT. Hypothetically speaking, if two people lose 20lb of bodyweight, one them loses 5lb of muscle and the other gains 5lb of muscle, then the first one has lost 15lb of fat and the other has lost 25lb of fat. I'm not the smartest guy in the world, but I think I'd rather be the second person out of those options. Besides that, as most of us regularly posting in this section understand, resistance training has significant implications for bone density, ADL's and physical independence, amongst other benefits.
Incidentally, I was doing some reading earlier today and one of the studies I looked at showed that resistance training may have greater benefits than cardio for controlling blood glucose levels in diabetics.SQ 172.5kg. BP 105kg. DL 200kg. OHP 62.5kg @ 67.3kg

Muscle gain = more anabolic metabolism = high basal metabolic rates = more calories burned on a regular basis. This is science. How do we get muscle gain? Although it can be done through diet, most people aren't that disciplined. Exercise is obviously the better choice here. I would slap anyone who calls themselves a professional and tell me different. The problem is most people's perception of "building muscle".

At the very least, muscle retention is what a client should be aiming for during a fat loss phase. Of course, your newbie will possibly gain some muscle and lose some fat at the same time.
I'm a firm believer in developing all energy systems for your general client. But strength is paramount prior to anything else IMO.
Nutrition, very important in transforming your body.

The problem is that we all agree, but there are people out there in various medical fields that don't. Obviously some dietitians have a bias. My father's doctor even told him to focus on diet because strength training was too vigorous for him. He is a 58 year old diabetic, 6'1" 245lbs. (~31 BMI), has hypertension, high cholesterol, and neuropathy. He would certainly be considered a high risk client, but also a perfect candidate for resistance training and exercise in general. I would not want him training with most personal trainers, either someone with a degree and years of experience, or a medically supervised program.
That being said, this is the perfect example where diet just isn't enough. We put way too much trust in what doctors say. People seem to forget that doctors are wrong quite a bit too, especially regarding topics that they don't study.

You don't need a degree, but I would prefer it if said person was working with a family member that was high risk. Experience is also a factor, but all things equal, I'll go with the person with experience and a degree instead of someone who completed a weekend, or online PT certification. I've spoken to many trainers that work with special populations in the past, but most of them have had success in spite of not knowing what they were doing. Their client could have just as easily had a stroke or other complications.

A degree from a well known school generally guarantees some consistent level of academic training. We all know there are hundreds of certifications out there. You can pass a certification without ever actually working with special populations.
I'm not saying that a degree guarantees that someone will be a good trainer, or vice versa, but there are more bad trainers without degrees than there are with degrees. Someone with a degree invested 4 years and a decent amount of money. A personal training certification takes no more than a few weeks or months of studying and a small investment. The barrier of entry is very low. That is all that I'm saying.
