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.
Carbohydrates also regulate muscle cell volume. You will notice that when carb intake is low your muscles will appear flat and smaller, because cell volume is diminished when carbs are restricted. This is because carbs are stored in muscle tissue as glycogen. Every gram of glycogen is stored with 2.7 grams of water. This can drastically effect the size of muscle cells.
That sour cherry is pretty sweet when it comes to your health. The results of a study conducted at the University of Michigan found that rats given high-fat foods along with tart cherries ditched nine percent more body fat than those in a control group over just 12 weeks. Cherries are also a good source of antioxidant pigment resveratrol, which has been linked to reductions in belly fat, dementia risk, and lower rates of macular degeneration among the elderly.
The conclusion? Intermittent fasting was just as effective for weight loss as daily calorie restriction. So if you struggle with daily food restriction, fasting might be an easier way to dial back the amount you’re eating without feeling completely deprived. Read more in-depth about how intermittent fasting works (and if you’ll be able to stick to it) here.
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.
Since doing cardio exercise is not as interesting as other exercises, people think it’s the only way to lose weight. But because it can get rather boring, people stop putting in the effort to lose weight altogether. The good news is, there are other ways to burn fat without having to spend long hours on the treadmill. The best way to reap the benefits of cardio is to incorporate it with weight-training.
REALITY: Fats and carbs both play a role in fat loss. Fats are responsible for hormone production, joint lubrication, and many other important health and muscle-building factors. Dropping your fats too low could compromise your health and your goals. Everyone's body and metabolism is different, so it's crucial to know how many grams of healthy fat you need to eat for a balanced nutrition regimen.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
