Why Do I Gain Weight in the Summer and Lose It in the Winter?

You wake up one morning and decide to hit the scales. To your dismay, you notice you’ve gained a pound in the last week – even though you ate healthy and were working out regularly.

You shrug it off and tell yourself that while it’s not ideal, at least you aren’t losing any weight. A few days later, you check the scales again and realize you’ve actually gained a pound since morning. Now you’re feeling discouraged and determined to find out why you’re putting on weight in the summer and losing it in the winter.

Here’s a look at the science behind why you gain weight in the summer and lose it in the winter.

Your Body’s Natural Defense Mechanism

For most people, summertime is an excellent time for shedding off those extra pounds. The days are longer, the temperatures are warmer, and there’s more sunlight to help your body produce vitamin D. All of these factors make it easier for your body to stay in a state of growth.

Your body doesn’t like being locked in a state of weight loss. Every year, at some point during the summer, you’ll have a freak out and decide to put on weight to make up for the weight you lost during the winter. It’s not that your body doesn’t know how to shed pounds – it just needs a little nudge to get started.

Changes In Water Intake And Fuelling Binge Eating

When the temperatures start to rise, your body starts pumping out more water to keep you cool and prevent dehydration. This increased water intake can also help you to overcome your fear of eating foods that are high in salt and fat. You may feel like you need to eat more in order to stay hydrated, which can lead you to gaining weight even if you stay indoors and avoid the sun. All of this is natural and completely normal. What isn’t normal is when this additional water intake leads to compulsive eating. It can happen if your dieting has become an obsessive habit or you’re driven to eat by negative feelings such as anxiety or depression.

A Combination Of Factors

Depending on your body shape, gender, and age, the reasons for your weight gain or loss may vary. If you’re carrying a bit of extra weight, it may be a combination of factors. Your body’s natural defense mechanism isn’t the only thing at play here. It’s a combination of changes in your hormones, vitamin D levels, and water intake that can lead to weight gain or loss. It’s not always easy to pinpoint the exact cause of your weight issues – but with a little bit of research, you’ll be able to discover the main reason why you’re gaining or losing weight.

By understanding the factors that affect your body’s weight, you’ll have a better idea of how to reach your goal weight. If you want to know why you put on weight in the summer and lose it in the winter, here’s a short list of everything that can contribute to it:
