As noted above, our bike racer study (Phinney 1983) involved 9 lean men locked up while eating a precisely controlled ketogenic diet for 4 weeks. In addition to daily weights, three methods were used to determine changes in body composition. As a group, these subjects lost 1 kg of body weight in the first week of the ketogenic diet, all of which was attributable to reduced muscle glycogen stores (which were directly measured). After that, their weights were stable for the next 3 weeks. Unfortunately in this study we did not have the opportunity to measure metabolic rate, but based on our body composition data, anything over a 3% increase in energy expenditure associated with the ketogenic diet would have shown up as non-water associated weight loss (by implication, a loss of body fat). Clearly these 9 men did not demonstrate an obvious increase in body fat loss in the first 4 weeks of keto-adaptation.
The available evidence shows that moderate carb restriction is effective in treating any female hormonal problems that might be driving weight gain. In this study of women with PCOS, for example, 30% of calories from carbs worked better than 55% of calories. On the other hand, an extremely low-carb diet is not necessarily the answer either: especially for women, extreme carb restriction can cause problems of its own, including hormonal dysfunction, amenorrhea (loss of normal periods), and infertility. Sweet potatoes are not the enemy! You can eat 1-2 starchy tubers (potatoes or sweet potatoes) every day and still be well under 30% of calories from carbs.
Invest in single-serving containers. The National Institute of Diabetes and Digestive and Kidney Diseases says that a serving size on a food label may be more or less than the amount of food you should eat, depending on your age, height, sex, and weight. Once you're done cooking, place the excess servings in the containers to eat for lunch or dinner tomorrow. That way, you won't polish off everything in one sitting.
About: Ruzele’s had weight issues her whole life, but it wasn’t until after her mother passed away in 2011 that the pounds really started to pile on. She ballooned up to 335 pounds and had a rock-bottom moment that led her to where she is today: 50 pounds lighter and on a mission to lose 130 more. Ruzele’s blog posts are short and sweet, but always delightful and full of musings, emotions, progress reports and the occasional vlog (which work oh-so-perfectly). Ruzele’s one to follow if you’re looking for someone who’s accountable and gets to the point, but still leaves you rooting her on day-in and day-out.
Hey Adam! I’ve gained almost 30lbs in the last year. My motivation for any athletic anything has tanked. I travel 100% of the time only home on weekends. It makes any routine for healthy eating difficult. If I’m lucky I have a small fridge and microwave in my room…fridge is most common. I am a huge snacker. I’ve gotten better. I snack on tricuits, and special K chips and granola/cereal bars, apples with peanut butter, etc… I drink wine or beer every day but would be the easier of the two to give up (snacking or alcohol).
The results of the current study showed that both protocols of rapid WL and slow WL caused a reduction in waist circumference, hip circumference, total body water, body fat mass, FFM, LBM, and RMR. Greater reduction of waist circumference, hip circumference, and FFM was seen with slow WL and greater reduction of total body water, LBM, and RMR was seen with rapid WL. It seems that the effect of slow WL in maintaining body water and LBM (as a metabolic tissue) was more significant than rapid WL.
3. Be realistic about which habits need to go. "When I was heavy, I'd eat French fries every single day, plus carbs at almost every meal—like a sandwich for lunch or bread with pasta for dinner. A diet so heavy in fried food and carbs just isn't conducive to weight loss. To lose the weight, I went from three large meals a day to six small meals, mostly made of fresh vegetable salads with lean meats and nuts. And no more bread!"
