Short answer: yes. Peanut butter can be part of a weight-loss diet — as long as you measure the portion rather than eyeball it. The problem isn't the butter itself; it's how easy it is to eat too much of it.
Why it keeps you full
Peanut butter combines protein, fat and fiber — all three slow digestion and help you feel full for longer. That's why a slice of toast with peanut butter, or an apple with a spoonful, often keeps you going longer than sweets with the same calories.
Large long-term observational studies have found that people who regularly eat nuts and peanuts don't tend to gain more weight than those who don't — provided total calories stay in check.
Where the risk is
Two tablespoons of Classic are about 194 kcal. Eat straight from the jar or spread it thickly, and a few hundred extra calories a day can slip in unnoticed.
Practical tips
- Portion: 1–2 tablespoons (15–30 g) a day is plenty;
- measure with a spoon or a scale — don't eat from the jar;
- pair it with fiber: apple, carrot sticks, oatmeal, whole-grain bread;
- read the label: pick a butter with no palm oil and no added sugar.
Which GULIANI jar
For weight loss the obvious pick is Classic — just peanuts and salt, 4.2 g sugar per 100 g and the highest protein in the range. The honey versions contain more sugar (Peanut Butter with Honey has 12.8 g per 100 g), so treat them more as a dessert.
