Eating for weight loss: Experts reveal how many meals you really need

How meal timing affects weight

Metabolism is the amount of energy, or calories, your body uses over a given period of time. Eating more frequently can increase metabolic rate, meaning you burn more calories.

This idea is partly linked to the thermic effect of food, which is the number of calories your body burns to digest food. Eating more often helps keep your metabolism active throughout the day, rather than only during two or three meals.

Larger meal portions have a stronger thermic effect, while eating fewer meals can limit this calorie-burning boost.

For weight loss, it’s generally best to eat 3–4 times a day, focusing not on meal frequency alone, but on maintaining an overall calorie deficit, choosing high-quality foods, and keeping a consistent schedule.

The time of day when you eat your largest meal also matters for blood sugar levels.

Research published in Clinical Endocrinology & Metabolism shows that having your biggest meal earlier in the day, such as at breakfast, can lower average daily blood sugar levels compared to eating your largest meal later in the day.

Is breakfast really the most important meal?

Research shows that people who eat breakfast regularly tend to have:

• Lower risk of obesity
• Reduced risk of type 2 diabetes
• Improved cognitive function
• Better heart health

However, the quality of breakfast matters. Regularly eating a less nutritious breakfast, like sugary cereals, pastries, or foods high in saturated fats such as bacon and sausages, may not provide the same benefits.

Instead, choose a breakfast high in protein, complex carbohydrates, fiber, and healthy fats to fuel your morning, maintain energy, and feel full longer.

Is intermittent fasting beneficial?

Intermittent fasting is a popular eating approach for people looking to lose weight. Limiting the hours during which you are allowed to eat, it also affects the number of meals you consume.

This method of eating may offer potential health benefits for various aspects of well-being and medical conditions, including:

• Weight loss
• Blood sugar control
• Digestive health
• Support for autoimmune disorders
• Cognitive function
• Hormonal balance
• Metabolic syndrome

Snacks between meals

If you prefer smaller, more frequent meals, you’ll likely include snacks throughout your day. Those who eat fewer, larger meals often skip snacks altogether.

Snacks can be a great way to curb hunger, boost energy, and provide extra nutrients. However, excessive snacking may lead to unwanted weight gain.

To make your snacks healthy, follow these tips:

• Plan ahead – this reduces the likelihood of reaching for ultra-processed foods.
• Include fruits or vegetables.
• Combine carbohydrates with a source of protein and/or healthy fat – this helps balance blood sugar levels and keeps you feeling full.
• Watch portion size – eat enough to satisfy hunger but avoid overconsumption.
• Limit or avoid foods and drinks high in added sugar or sodium.
