Health conditions Certain medical conditions can lead to unexplained weight gain. These conditions may include: Endocrine disorders. These include conditions like thyroid hormone deficiency, insulin resistance and polycystic ovary syndrome (PCOS).
When you don't eat, your body releases the stress hormone adrenaline which is very toxic to the body and damaging to the liver. Your liver then becomes sluggish and can't process our the fat so your body stores it. This is how you gain weight when you're eating less.
Certain diseases and medicines
In some people, obesity can be traced to a medical cause, such as hypothyroidism, Cushing syndrome, Prader-Willi syndrome and other conditions. Medical conditions, such as arthritis, also can lead to decreased activity, which may result in weight gain.
You Might Be Eating Too Little
This phenomenon is called “starvation mode,” and while your body isn't actually starving, it will naturally hold onto whatever calories it receives in an effort to help you maintain your energy balance.
In short, you burn less calories at the end of the day putting you at risk for increased weight gain. When we skip meals, we often “make up” for it later in the day. If you skip breakfast, you may have a bigger lunch because you are starving by the time lunch comes around.
Do resistance training and high-intensity workouts – Lifting weights and doing exercises that use resistance weights or the weight of the body helps build muscle. Muscle mass has a higher metabolic rate than fat, which means that muscle mass requires more energy to preserve and may increase your metabolism.
Fluid retention
The amount of fluid in your body changes throughout the day. It's totally normal for your weight to change up to four pounds in a single day, based on your fluid levels. Fluid retention, or edema, is when a lot of fluid builds up in the body. This can cause a sudden weight gain of 15 or more pounds.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
What causes obesity & overweight?
People naturally lose muscle after 40, especially women after menopause. Because muscle burns more calories than fat, this can slow down your metabolism and make it harder to shake those stubborn pounds.
Certain types of cancer can cause weight gain. Ovarian and colorectal cancer, for example, may cause fluid buildup in the legs or abdomen. This type of edema is called ascites.
Water is more than just a thirst-quencher. It offers various benefits that can aid in weight loss. These include boosting metabolism, suppressing appetite, aiding in detoxification and enhancing exercise performance.

Here are just some medical conditions which can cause sudden weight gain:
How to get rid of water weight
If you have gained 7 pounds in one week, this could be due to factors such as water retention, certain medications, or a medical condition. Water retention is caused by excess fluids in the body as a result of consuming too much salt or carbohydrates, being dehydrated, or hormonal changes.
Fluid retention in the body: If you experience rapid weight gain, this signals underlying conditions that impact the heart, liver, and kidneys, as well as an adrenal problem, polycystic ovarian syndrome (PCOS) and hypothyroidism. Poor sleep: Not getting enough quality sleep leads to weight gain.
When you eat too few calories, your body can react in ways that might cause weight gain instead of loss. 1. Stress Hormones: Low calorie diets can increase stress hormones like cortisol. High levels of cortisol might make your body hold onto fat rather than burn it.
Of course, overeating isn't the only stress-related behavior that can add pounds. Stressed people also lose sleep, exercise less, and drink more alcohol, all of which can contribute to excess weight.

When comparing fasting in the night vs morning, evidence gravitates toward skipping dinner rather than breakfast. While some research studies agree that you can lose weight when skipping breakfast, there can be health risks such as elevated cholesterol levels and increased risk of heart disease [9][10].
Your most consistent and "true" weight is generally in the morning, after using the bathroom and before eating or drinking anything. This provides the most accurate baseline because your body has processed the previous day's food and fluids overnight, resulting in less fluctuation from digestion, water intake, and daily activities. Weighing at the same time, in the same minimal clothing, and under consistent conditions (like in the morning) helps track trends better than weighing at night or randomly.
If you gain 2 to 3 pounds a day, or 5 pounds a week, you should see your provider. It's also important to see them if you gain 5% or more of your body weight in a month. This type of unexpected weight gain may be a sign of an underlying health condition.
