When the body is expending more energy than it is consuming (e.g. when exercising), the body's cells rely on internally stored energy sources, such as complex carbohydrates and fats, for energy. The first source to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 65% of which is stored in skeletal muscles and the remainder in the liver (totaling about 2,000 kcal in the whole body). It is created from the excess of ingested macronutrients, mainly carbohydrates. When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to generate energy.[24] The primary by-products of metabolism are carbon dioxide and water; carbon dioxide is expelled through the respiratory system.

Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.
A particular diet may be chosen to seek weight loss or weight gain. Changing a subject's dietary intake, or "going on a diet", can change the energy balance and increase or decrease the amount of fat stored by the body. Some foods are specifically recommended, or even altered, for conformity to the requirements of a particular diet. These diets are often recommended in conjunction with exercise. Specific weight loss programs can be harmful to health, while others may be beneficial and can thus be coined as healthy diets. The terms "healthy diet" and "diet for weight management" are often related, as the two promote healthy weight management. Having a healthy diet is a way to prevent health problems, and will provide the body with the right balance of vitamins, minerals, and other nutrients.[4]
A second approach is to follow a nutrition plan that doesn’t focus on managing a calorie level, but instead focuses on optimizing the body’s ability to burn fat. The body is able to burn fat when insulin levels are low. Eating fat has no effect on insulin, and protein has a very small effect. That’s why we encourage people to base their diet on non-starchy vegetables, high-quality protein sources and healthy fats. That’s also why reduced-carbohydrate diets have been shown to be more effective for fat loss than low-fat diets. In fact, they’ve been shown to be more effective for fat loss even when the low-fat groups are on a set calorie intake and the low-carb dieters are allowed to eat as much as they want to.
Pros: Technically a subtype of low-carb diet, the keto diet is unique: By depriving your body of carbohydrates, you not only force your body to become fat-adapted, but also, if you keep protein low as well, elevate your levels of ketone bodies, which is basically a sign your body is running on fat. The keto diet puts you in a unique metabolic state called ketosis wherein your brain burns ketones instead of glucose—and, in doing so, supposedly leads to clearer thinking. Physically, eating such a high amount of fat significantly increases your body’s ability to burn body fat, according to the study analysis. Research also shows keto athletes have a higher VO2 max, and are able to lose fat without losing strength or power.
“Don't like eating meat?” asks Ginger Hultin, RDN, a dietitian in private practice in Seattle and a spokesperson for the Academy of Nutrition and Dietetics. “Then don't be paleo! Travel a lot and rely on eating out? The DASH diet may end in frustration for you.” The bottom line: The diet you choose needs to be safe and effective, while taking into account your lifestyle.
Protein serves a dual role in helping you trim down belly fat by increasing muscle mass and metabolism, while also helping stave off hunger. Research shows that a higher-protein diet increases thermogenesis, which means you burn more calories. Further, eating protein leads to an increased feeling of satisfaction after the meal, often causing you to eat fewer calories later in the day. These High-Protein Breakfast Tacos are the perfect way to start your morning and will keep you feeling full until lunch.

Most people I have met knows someone who is heavy, but disabled in some way that makes it difficult or impossible to work out, or someone trying to lose weight after an injury. I encourage them to move their bodies as much as they can, if it means lifting weights while on the couch, or just working a little harder in physical therapy you can do something to move more.
