Over the past five or six days of this protocol, you’ve been in deep ketosis and burning only fat, but you haven’t had to be particularly calorie restricted. In order to reset leptin levels and prevent a large drop in energy levels, you need to re-feed. Contrary to our normal recommendations, you need to pound down the carbs. When it comes to normalizing leptin levels, fat has no effect, while carbs are going to send them sky high.
Jame LeCheminant and colleagues looked at the short-term effect restriction of night eating had on daily calorie consumption, weight trends, and even mood associated with this deprivation. They recruited 29 young men and asked them to avoid consuming calories (water was okay) between the hours of 7 p.m. to 6 a.m. for two weeks. During these two weeks the participants recorded every bite they consumed, and their weight, mood, and level of hunger at breakfast were monitored. There was a one-week break, and then for two more weeks (a control period) the subjects were monitored as they returned to their usual way of life. That’s it. There were no other interventions or exercises to perform.
Is a calorie truly a calorie? Not always, because different types of calories can affect your body and your results differently. Dietary fat, for example, is more "fattening" than protein or carbs because it's less likely to be used to build your body. Granted, carbs can potentially make you fat, but they also directly fuel your training. Protein? That's a no-brainer: It builds muscle. Fat does neither, but it isn't useless; moderate amounts of it support vitamin absorption and help manufacture hormones.
When Johns Hopkins researchers compared the effects on the heart of losing weight through a low-carbohydrate diet versus a low-fat diet for six months—each containing the same amount of calories—those on a low-carb diet lost an average of 10 pounds more than those on a low-fat diet—28.9 pounds versus 18.7 pounds. An extra benefit of the low-carb diet is that it produced a higher quality of weight loss, Stewart says. With weight loss, fat is reduced, but there is also often a loss of lean tissue (muscle), which is not desirable. On both diets, there was a loss of about 2 to 3 pounds of good lean tissue along with the fat, which means that the fat loss percentage was much higher on the low-carb diet.
Don’t think going low-carb on the overfeed day is going to improve the results. It will make them worse. You do not need to avoid fat, but you do need to work on making sweet potatoes, yams, and white rice the bulk of your diet for this one day. You can drown your sweet potatoes in butter or not; it doesn’t matter as long as you eat the potatoes. It’s important to choose glucose based carb sources like sweet potatoes and Taro over fruit. Fructose is 10-20% more lipogenic (fat forming) during overfeeding than glucose.
EFAs stand for Essential Fatty Acids. Just as the name implies EFAs are essential to the human body because play a role in many different biological processes. Essential fatty acids differ from others fats in that they cannot be synthesized within the human body. This means that EFAs must be consumed through the diet. If not enough EFAs are consumed the body will sense that it does not have the nutrients that it needs to function properly. As a result it will essentially “hold on to” body fat. This is just one of the reasons EFAs are so important though.
Eat small meals more often. In simple terms, eating spurs your metabolism — the process by which your body turns food into energy. Eating more often, then, may kick your metabolism into a higher gear more times per day (e.g., if you eat six times a day, you get six “spikes”). But, you must make sure that eating more often does not also mean eating more; it’s essential that you reduce your overall average daily calories.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
This results in lifting less weight for less reps while your in the gym. If you are not able to train as heavy due to energy needs this will surely lead to even greater muscle tissue loss. So if carbs are not available it will have a double whammy effect on muscle loss. Muscle tissue will be sacrificed to meet energy demands as well as muscle losses due to decreased training demands. You work hard for your muscle so don’t let it all go to waste.
Based on your results, a specialist will determine if you burn fat well or not. According to Dr. Arad, "If you're able to burn fat well, do a type of exercise that maximizes fat-burning, like a moderate-intensity run." If your results show that you don't burn fat well, "You may benefit from doing high-intensity exercise, like high-intensity interval training," Dr. Arad said.
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
