I'm confused about "under 6 servings of carbs". Your body doesn't typically count servings, but grams would be a more accurate measurement. That is still a lot of sugar you consume. Saturated fats are not bad for your body - and you will never find a clinical trial that shows otherwise.
Exercising does not work for losing weight. LPL (lipoprotein lipase) enzymes run throughout your body and work to channel fatty acids in your bloodstream to many different types of cells. When you work out, they channel fatty acids to your muscles. This is great as it temporarily makes your body leaner. However, when you stop exercising, your muscle's LPL activity shuts down, and your fat cell LPL activity is kicked into high gear, flooding fatty acids into storage. Your body is essentially preparing for the next onslaught of work. This makes you crave more carbohydrates, which when ingested - your insulin response is to store fat.
This is why you see a lot of marathon runners gain weight while training - and I would surmise they work out harder than you.
'Your metabolism is slowing' is a common phrase to hear. What it really is is that you are becoming more insulin resistant. This means your body is more susceptible to gaining weight, you may eventually become insulin resistant - which can lead to obesity and type II diabetes.
The typical advice you'll get from a doctor is exercise and low-fat or calorie-restricted. Low-fat diet is a fad diet created by the McGovern Committee in the 1970s. Look what it has done to our world - type II diabetes is rampant and obesity is crazy. The JAMA just came out with a report - see second source, with headlines including:
Nearly 36 percent of adults and 17 percent children are obese and
The number doubles when the prevalence of people who are simply overweight instead of obese are also taken into account.
So around 70% of adults are overweight and 35% of children are overweight.
Over the past several decades, the ingestion of animal fats has gone down, while the ingestion of carbohydrates has gone up significantly. This is due to the cheap nature of carbohydrates - and the benefits that come with packing in carbs (longer shelf life, taste etc).
Anyway, check out the book and you may learn some very important information. You can read some pages for free online before you buy it.
And about the "it is not Atkins" guy - there is nothing wrong with Atkins, or more severely reduced carbohydrate plans. Decreasing carbohydrates enough puts your body into ketosis, which uses dietary fat (mostly) for fuel and ketones for brain function. It keeps your blood-glucose and insulin levels way low, which greatly reduces your chance of heart attack, stroke, many types of cancers and more.
So while some individuals may want to just lose weight by cutting out grains and such (which is good), others who go with very low-carbohydrate lifestyles desire an even better and lasting affect on their longevity and well-being.
