Is it possible to starve and not lose weight

They might drop pounds rather quickly, just look at the Biggest Loser for evidence of that. But what really happens to their bodies? What are the short and long-term health effects of starvation on body composition? Body composition is the term used to describe the components that make up your body: fat and fat-free mass. Instead, your goal is twofold: reduce fat mass while maintaining or increasing Lean Body Mass. But why should you focus on changing your body composition instead of weight loss?

That is because muscle is more compact than fat. So focusing on body composition, as opposed to fat loss, can help you improve your overall appearance and reduce body fat while increasing strength. The standard model of weight loss is calories in vs calories out. If you consume more calories per day than what you burn, you will gain weight; by burning more calories per day than you take in, you will lose weight.

Having a calorie restriction is important if you are trying to see the number on the scale decrease. As discussed earlier, many people choose the all-or-nothing, die-hard approach to weight loss and opt for calorie levels far lower than what is recommended, prompting them to lose weight rapidly.

Likewise, a study on mice found lean mass and lean muscle mass were sacrificed during starvation; however, body fat stores were relatively the same in mice on a control diet and obese mice on starvation diets. Weight loss via starvation causes individuals to lose significant amounts of lean muscle mass and Lean Body Mass, which encompasses water, bones, organs, etc.

Reducing the mass of your bones is problematic, as that decreases bone density and can make you more prone to injury. Conversely, increasing Lean Body Mass increases bone strength and density, a common concern for many Americans as they age. One study using human participants indicated dropping significant amounts of calories from the diet lead to significant weight loss and decreased lean muscle mass. However, participants also gained back nearly all of the fat they lost , within 8 years.

This prompts the discussion and understanding of an important topic- metabolism. More so, chronic starvation leads to changes in metabolism. Metabolism and resting metabolic rate are directly linked to Lean Body Mass. A person with greater body mass will require more energy to function day to day, thus will have a larger basal metabolic rate BMR. As weight decreases, so does BMR. If you go below this number, your body will be forced to break down these muscle stores in order to create energy.

Starvation diets have far-reaching negative effects on the body. Starving to lose weight changes the metabolism, reduces lean muscle, reduces bone density, and decreases strength. Perhaps you opted for an ultra-low-calorie diet, placing your body in starvation mode. So far, your body has also responded by losing muscle and decreasing BMR. But something else interesting happens to the body after a period of starvation.

What does that mean? The body tunes itself to focus on significant weight loss at the expense of body fat mass, lean muscle, and other lean mass. It reduced its basal metabolic rate. The main problem is that this type of diet is too hard to maintain. You may also be missing out on essential nutrients as crash diets can be limited in the variety of food consumed.

Your body will be low on energy, and may cause you to crave high-fat and high-sugar foods. This can lead to eating those foods and more calories than you need, causing weight gain. Learn more about a healthy diet and how to lose weight sensibly.

Metabolism describes all the chemical processes that go on continuously inside the body to keep you alive and your organs functioning normally, such as breathing, repairing cells and digesting food. These processes need energy and the amount of energy required varies between individuals depending on factors such as body size, age, gender and genes. It is claimed that certain foods and drinks can increase your metabolism by helping the body to burn more calories and aid weight loss.

There is little scientific evidence for this. Beware that some of these products may contain high levels of caffeine and sugar. Find out how to speed up your metabolism.

Not all slimming tablets are effective or safe to use to lose weight. There are a number of prescribed medicines available from your GP for weight loss. There are also other un-prescribed, unlicensed weight loss products available on the market which may contain ingredients that are harmful to health. Be cautious. Foods labelled "low fat" have to contain no more than a specific amount of fat to legally use that label. If a food is labelled as "low-fat" or "reduced fat", it should contain less fat than the full-fat version, but that doesn't automatically make it a healthy choice: Check the label to see how much fat it contains.

Some low-fat foods may also contain high levels of sugar. Many people need a snack in-between meals to maintain energy levels, especially if they have an active lifestyle. Choose fruit or vegetables instead of crisps, chocolate and other snacks that are high in sugar, salt and fat.

Water does not cause you to lose weight, but it does keep you hydrated and might help you snack less. Water is essential for good health and wellbeing. Sometimes thirst can be mistaken for hunger — if you're thirsty you may snack more. Skipping meals is not a good idea. Here are a few ways sleep can help you lose weight.
