4 Lean Proteins You Can Eat Daily To Boost Metabolism And Lose Fat Over 40  

Eggs Eggs are a protein-rich, metabolism-boosting morning staple. Eggs are delicious, adaptable, and good for over-40s. Kimszal says 6 grams of protein per egg "can increase the thermal effect of food and may speed up the metabolism."

In addition, "studies have shown that eating eggs not only increases your metabolism but also increases your satiety levels," which is fantastic for weight loss because "feeling fuller for longer means that you are less likely to eat more during the day." Avoid midday processed snack binges!

Yogurt   Greek yogurt, which has many health benefits, is another great breakfast item. Greek yogurt has 15-20g of protein per serving, Peralta says. "That's more than enough for a snack," plus it makes a satisfying, metabolism-boosting breakfast.

Even better, you can top your yogurt bowl with nutrient-rich, weight-loss-friendly toppings for a delectable meal your taste buds and body will appreciate.

Lean meat Although there are many plant-based lean proteins, we can't talk about protein without meat. Lean meats like poultry and fish are helpful for weight loss, while red and processed meats can be harmful.

"Lean meats, including chicken, turkey, and fish, are excellent protein options," Herries explains, as "this is because the majority of calories in lean meats come directly from protein."

Tofu Plant-based proteins work too. Tofu is great for boosting metabolism and losing waistline inches. "Tofu is a lean protein as it is low in saturated fats and calories, providing a nutrient-dense option for those looking to manage their weight

"Its high protein content also contributes to a higher thermic effect of food, potentially boosting metabolism by requiring more energy for digestion and absorption."
