Weight-loss programs often accentuate the difference. When sedentary men and women both start exercise programs, men tend to lose body fat, while many women don’t. In one study out of England, men and women were each put on commercial weight-loss programs such as Atkins, Slim-Fast and Weight Watchers. Two months in, the men had lost twice as much weight as the women -- and three times as much body fat. But by six months, the rate of weight loss had evened out between the genders.
The key to losing weight is to burn more calories than you eat and drink. A diet can help you to do this through portion control. There are many different types of diets. Some, like the Mediterranean diet, describe a traditional way of eating from a specific region. Others, like the DASH eating plan or a diet to lower cholesterol, were designed for people who have certain health problems. But they may also help you to lose weight. There are also fad or crash diets that severely restrict calories or the types of food you are allowed to eat. They may sound promising, but they rarely lead to permanent weight loss. They also may not provide all of the nutrients your body needs.
Cordain explains that high intake of fruits and vegetables is one of best ways to reduce chances of cancer and heart disease. He notes that protein has twice the calorie burning effect of fat and carbs and is more satiating than both. He explains that starch, fats, sugars, and salts together cause us to keep eating. So if we limit our diet to fruits and vegetables and/or meat, we’ll stop eating when we’re full. And if you stop eating when you’re full, you’ll lose weight and won’t get fat. And as you lose weight, your cholesterol will improve (regardless of what you eat). This all makes sense and can’t really be disputed. If you want to lose weight, the Paleo diet will get you there and probably quickly. But Cordain’s hypothesis applied to long-term health falls short.
I think the most important changes though is the removal of the “white carbohydrates” and the sugary drinks. These and other highly processed and pre-packaged foods that have become our western culture staple is really what’s contributed to obesity and so many other health issues. Just getting that out of your diet and replacing it with natural, low-GI, high-fiber foods will melt the fat off quicker than you can imagine.
I have been following the slow-carb diet for nearly 3 weeks with no significant weight loss. I will admit I have made a few tweaks to fit my lifestyle. I go to the gym at 5:30am and do not have time or the desire to eat a big breakfast before going. So I normally make a whey protien shake with water and about 1/4 cup frozen berries (I know fruit is a no-no) when I get home from the gym at 7. I then eat breakfast – eggs, black beans and spinach at 10. Lunch is either a salad with beans or slice of deli turkey or chili. I have not eaten any grains, sweets etc… I do use milk in my coffee instead of heavy cream. Why is heavy cream a better choice? I do have a glass of red wine at night and an occasional serving of sugar free gelatin. I take a spin class 2-3 days a week and run 20 miles per week as I am training for a Ragnar Relay.
“When clients come to me, many of them have been through the diet wringer. They’ve tried every fad and gimmick and, of course, they’ve failed to maintain long-term success. The key to weight loss is to never feel like you’re on a diet, because diets don’t work. If you feel deprived, you will never make it past a few weeks. The only way to achieve long-term weight loss is to learn to appreciate food as fuel and slowly replaced processed food that cannot properly energize the body with real food that can. After a while this will become second nature and won’t feel like a daily struggle.” — Laura Burak, MS, RD, CDN
