Can I Eat Nuts While Fasting?

No, you cannot eat nuts during your fasting window, regardless of the intermittent fasting plan you’re on. Eating nuts while fasting will kick you out of the fasting state, a metabolic state that happens 8-12 hours post your last meal, where your body flips from using blood glucose to tapping into fat stores for fuel.

So, do nuts break a fast? Yes, nuts break a fast. While they make for excellent and healthy snacks loaded with polyunsaturated fatty acids, they are calorie-dense. Eating almonds, peanuts, walnuts, pistachios, or consuming calories in any form can trigger a metabolic response and break a fast. A 2023 study by Terrence Sanvictores and colleagues from Touro University and the University of Louisville shows that even certain medications and physiological states, such as taking a COX2 inhibitor or experiencing hypoglycemia, can potentially disrupt a fasting state.

However, you can enjoy nuts during your non-fasting window; cashews, pecans, and hazelnuts are packed with healthy fats, plant-based proteins, and insoluble fibers that are great for keeping you satisfied and nourished. Just remember to watch your portion sizes because nuts are calorie-dense.

Can I eat nuts during intermittent fasting?

Eating nuts during intermittent fasting is a no-go if you want to stay in a fasting state, as Terrence Sanvictores, Jarett Casale, and Martin R. Huecker note that fasting involves a restriction of food intake to improve various health markers. In the fasting state, the body switches from using blood glucose to stored glycogen, and eventually to fat and protein for energy, meaning eating anything with calories, like nuts, would interrupt this process. Studies, including those observing Ramadan, have shown that any caloric intake can shift the body’s energy utilization, breaking the fast.

Whether you can enjoy nuts during a religious fast hinges on the particular guidelines of the fast you’re following. For example, a study conducted by John F. Trepanowski and Richard J. Bloomer indicates that certain fasts, like the Greek Orthodox fast, resemble vegetarianism and may allow nuts.

In contrast, others, such as Islamic Ramadan, require abstaining from all foods during daylight hours.

In a 2007 study conducted by Barbara Strasser and her team, they emphasized that fat loss is mainly linked to creating an energy deficit, rather than the specific foods you consume. So, feel free to give intermittent fasting a try, but remember, it’s not the only path to success.

I’ve experimented with intermittent fasting, OMAD, calorie counting – you name it! And guess what? They all did the trick. So, the real deal here is achieving that calorie deficit. The fasting state can bring extra perks besides weight loss, but at its core, it’s all about the calories in and out.

As long as you maintain a calorie deficit, you can include nuts in your diet and continue making progress with your weight loss journey.
