Here’s a scene that plays out in almost every client call I receive from June through September: A woman tells me she’s inexplicably exhausted and short on fusion, even though she sleeps well and exercises regularly. She is convinced that there is something deeper going on.
Next, we look at his food diary.
Breakfast is a smoothie or just coffee. Lunch is a small salad or whatever is left in the fridge. Afternoon snacks are watermelon or a handful of crackers. Around 4 p.m., it runs on steam. She blames her hormones or her kids’ chaotic summer schedule. But more often than not, the simplest explanation is the right one: it is simply not eating enough.
Summer is the season when we are most likely to accidentally stop eating properly. And unfortunately, it’s disguised as wellness. Today we remove the myth that “eating lighter” in summer means eating lessand talk about what your body needs to feel good as temperatures rise.
The myth that lighter is better
There is a pervasive narrative that summer meal should be delicate and cold. Smoothie bowls. Small plates of picky snacks. Salads that look amazing on Instagram but leave you hungry 90 minutes later. None of these foods are inherently bad, but when they become the staple of your summer diet, you find yourself in a constant calorie deficit. And your body interprets this as stress. And here’s the irony: this pattern is often reinforced by persistent pressure from “summer body” culture. Even if you are past this mindset intellectually, the message is everywhere.
What is happening in your body
Let’s talk about the physiological reason your appetite decreases due to heat (for context, it’s worth understanding). When outside temperatures rise, your body redirects blood flow from your digestive system to your skin to help dissipate heat. Food consumption decreases in hot environments in almost all cases species studiedus included. This is partly because digesting food generates internal heat (known as the thermal effect of food), so your body naturally suppresses hunger to avoid adding more heat to a system that is already working hard to cool itself.
Is your appetite lying to you?
Emerging research Also suggests that heat can reduce levels of ghrelin (your hunger hormone) while increasing satiety hormones such as GLP-1. On top of that, dehydration can simultaneously mimic hunger and suppress appetite, making it harder to read your body’s signals. In other words: we are not necessarily less hungry in summer. You feel less hungry because your body prioritizes temperature regulation over digestion. Your caloric and nutritional needs has not changed! On the contrary, they increased, especially if you are more active or sweat more than usual.
Why it’s more important than you think
Chronic undernutrition, even an “accidental” one that happens in the summer, triggers a stress response in your body. When you don’t eat enough, your cortisol increases. And high cortisol disrupts blood sugar levels, leading to the exact symptoms that so many women describe in the summer: low energy, brain fog, irritability, and intense desires which seems to come out of nowhere. It also disrupts your hormones. Undernutrition signals to your body that resources are scarce, which can suppress thyroid function, disrupt your menstrual cycleetc. If you’ve ever noticed that your PMS gets worse in the summer or that your cycle becomes irregular in the warmer months, your intake may be a factor.
What Eating Enough Looks Like in Summer
Eating enough in summer doesn’t mean forcing yourself to eat large meals when you’re not hungry. It means to be intentional it’s about giving your body what it needs, even when your appetite isn’t sending the usual signals.
Build your plate around protein. This is non-negotiable, whatever the season. Protein stabilizes your blood sugar, keeps you full, and prevents the cycle of spikes and crashes that makes summer afternoons unbearable. Aim for at least 25 to 30 grams with each meal. If a smoothie is your favorite breakfast, make sure it contains a scoop of protein powdera generous dollop of Greek yogurt and something more substantial than just frozen fruit.
Eat meals, not just snacks. A bowl of berries is not lunch. A handful of crackers and hummus is not dinner. Snack plates are delicious, but they must include protein and fat to be considered a real food. Build your summer meals around same structure you would use it in any other season.
Favor cold meals that are still substantial. This is where summer dining gets fun! A dinner without a cook it doesn’t have to be a small caprese salad. Think: refrigerated cereal bowls with salmon, avocado and tahini vinaigrette. Cucumber boats stuffed with chickpea salad. Cold sesame noodles with shredded vegetables and edamame. A halloumi salad It’s Pinterest worthy. These are light and refreshing meals, but provide the nutrition your body demands.
Hydrate yourself with food, not just water. Water-rich foods like cucumber, melon, tomatoes, and citrus fruits contribute to your fluid intake while providing electrolytes and micronutrients. Add a pinch of sea salt to your water for better mineral absorption and don’t underestimate the power of good gut health promoting nutrient absorption during the warmer months.
Eat on a schedule, even if you’re not hungry. When your appetite is suppressed by the heat, it helps to eat on time rather than waiting for hunger cues that might not occur. Aim for something substantial every 3 to 4 hours and try to eat breakfast within 90 minutes of waking up. This keeps blood sugar stable, prevents the cortisol cascade, and ensures you don’t catch up by 8 p.m.
Simple Ways to Stay Fueled (Without Feeling Heavy)
As a nutrition consultant, here are some small changes that make a noticeable difference:
- Brew once, assemble all week. Cook a batch of quinoa, grill a few chicken breasts and prepare chia pudding. There’s also something to be said for making a salad without wilting. For example, rinse and drain a can of chickpeas, hearts of palm, artichokes and black olives. Chop the hearts of palm and mix the mixture. During the week, supplement with balsamic, olive oil and your choice of protein and/or more fresh vegetables for a high-fiber lunch!
- Make your smoothie count. Blend protein powdera handful of spinach, some frozen cauliflower (you won’t taste it), a tablespoon of nut butter and a frozen banana. It’s a meal. A smoothie with just fruit and oat milk? It’s a sugar spike followed by a crash.
- Keep high-energy snacks visible. Hard-boiled eggs, nut butter packets, cheese, trail mix and protein bars should be within easy reach (and not buried in the back of the refrigerator behind the grapes).
- Don’t skip dinner because it’s hot. Easier said than done, but cook a meal. There is no need to involve the oven. A simple plate of smoked salmon, avocado, a baguette and a handful of cherry tomatoes constitutes dinner.
Eating in summer shouldn’t be minimal
The myth that summer meals should be minimal is just that: a myth. Your body needs fuel to feel good, sleep well, balance your hormonesand to show up for the season with energy and clarity. Contrary to what we are led to believe (especially as women), eating enough is not incompatible with the feeling of lightness. In fact, it’s the only way to get there.
