Lack of sleep throws your body’s hormone levels off balance which then impacts your hunger levels the next day. The 2 hormones that affect our appetite are ghrelin (the hormone that makes us feel hungry) and leptin (the hormone that makes us feel full). When we don’t get enough sleep, the level of ghrelin rises while our leptin levels drop. This causes you to feel hungry and overeat.
If you're dehydrated, it can be hard to tell if you're hungry or just thirsty. If you're craving a mid-day snack, have a glass of water and wait a few minutes before reassessing how hungry you really are. Water also helps food move through your digestive system, lessening feelings of bloating. It's a good idea to keep a water bottle with you throughout the day. Add in cucumber slices or fresh fruit to infuse flavor.
Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
This kind of strength training recruits fast-twitch muscle fibers, which increases fat burning, says Shore. Although you could see a small increase in the scale as you build muscle, keep in mind that muscle is more dense than fat. That means it’s very likely that you're losing fat while gaining muscle, so don’t stress, says Shore. To keep up your progress, aim to increase the amount of resistance you use when your current weight becomes too easy to lift, says Shore.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
