Can Eating More Help You Lose Weight? When It Works and Why

Yes, eating more can help you lose weight if you are eating so little that you cannot stick to it, drinking your calories, or eating small portions of calorie-dense food. More food volume and more protein usually make a calorie deficit easier to hold. You still need a deficit. You stop starving yourself to get it.

How can eating more lead to more weight loss?

There are three situations where I see it happen with clients.

1. They cut calories so low that they binge on weekends, so their weekly average is not low at all.
2. They waste a big part of their calories on drinks and snacks that do not fill them up.
3. They eat foods that are tiny for the calories, so they are hungry all day.

Fix those and they eat a bigger plate of food, feel better and lose more over a month.

Is starvation mode real?

Partly. When you diet, your body does burn a bit less energy than expected. You lose some tissue, you move less without noticing and your hormones shift. Researchers call this adaptive thermogenesis, and it is real, but it is small (Rosenbaum and Leibel, 2010). It does not make you gain weight while you are truly eating very little.

What actually happens is that very low calorie diets are hard to hold. Hunger wins, the weekend turns into a free for all, and the scale goes up. So the old line in this post saying too few calories causes weight gain was not quite right. The weight gain comes from the rebound eating, not from the deficit itself.

If you have been eating very little and the scale has stalled for weeks, add back 100 to 200 calories a day, mainly from protein and vegetables, and watch the trend for three weeks. Many people find they keep losing at the higher intake because they stop rebounding. If you have a history of disordered eating, work with a registered dietitian.

Why should I stop drinking my calories?

Juice, soda, sweet coffee drinks and alcohol add calories without filling you up. A medium sweet coffee drink can carry 300 to 400 calories. Swap it for black coffee or a lighter version and you have room for a full meal. Eating a piece of fruit instead of drinking juice gives you more fiber and keeps you full longer for the same sugar.

Which foods let you eat more for fewer calories?

Go for foods with a lot of volume, water, fiber or protein for their calories:

• Vegetables of almost any kind, especially leafy greens, broccoli, peppers and zucchini
• Fruit like berries, melon, apples and oranges
• Potatoes, oats and beans
• Lean protein like chicken breast, white fish, egg whites, Greek yogurt and cottage cheese
• Broth-based soups

Cutting back on heavily processed foods matters here too. People in one controlled study ate about 500 more calories a day on an ultra-processed diet than on a minimally processed one (Hall et al., 2019).

Does fasting let you eat more?

Intermittent fasting puts your meals in a shorter window, which means each meal can be bigger. That is the main reason it helps some people. It does not make your body burn fat faster than a normal diet at the same calories (Lowe et al., 2020). I cover it fully in what is intermittent fasting.
