One piece of cheesecake (1/6 of a 17 oz cake, approximately 80g) contains 257 calories with 4.4g of protein, 20.4g of carbs, and 18g of fat. Per 100g, cheesecake provides 321 calories. The high calorie density comes from cream cheese, eggs, and sugar. The sugar content is notable at 21.8g per 100g (17.4g per slice), which spikes blood sugar quickly. Cheesecake has modest micronutrients, including vitamin A (159mcg per 100g) and calcium (51mg per 100g) from the dairy ingredients. A standard restaurant-size slice, which is often 150 to 175g, can easily reach 400 to 600 calories. Cheesecake is a high-calorie, high-fat dessert that should be tracked carefully if you are watching your intake.

Health Benefits of Cheesecakes
Cheesecake does not offer meaningful health benefits from a nutrition standpoint. It is a calorie-dense dessert with significant sugar and fat and minimal vitamins or minerals. That said, there is a legitimate role for desserts in a sustainable diet, and cheesecake is worth understanding nutritionally so you can make informed decisions.
The cream cheese and eggs in cheesecake contribute some protein (5.5g per 100g) and vitamin A (159mcg per 100g). These are minor contributions given the calorie cost.
From a diet strategy perspective, completely restricting desserts like cheesecake often leads to bingeing. A planned single slice (257 calories) can fit into a moderate calorie deficit if you account for it. The fat content slows digestion, which means the sugar spike is somewhat blunted compared to eating pure sugar or hard candy.
For anyone who is bulking, cheesecake is a convenient calorie-dense food. One NLEA serving (125g, about 401 calories) can fill calorie gaps on high-training days. It is not the ideal source of those calories nutritionally, but calorie surplus is calorie surplus.
The key is knowing exactly what a slice costs you: roughly 257 to 400 calories depending on serving size, and fitting it into your day intentionally rather than eating it mindlessly.
Dietary Considerations
Cheesecake is not suitable for vegans, dairy-free, or gluten-free diets in its traditional form. The graham cracker crust contains gluten and the filling contains cream cheese, eggs, and dairy. It is definitely not keto-friendly due to the sugar and carb content of the crust. For weight loss, cheesecake is a high-calorie, low-satiety food. It is not filling relative to its calorie count because the sugar does not provide lasting satiety the way protein or fiber does. If you are going to eat cheesecake while dieting, keep the portion to a single slice, eat it after a high-protein meal so you are not eating it on an empty stomach, and count every calorie.

Frequently Asked Questions
How many calories in a slice of cheesecake?
A standard slice of cheesecake (1/6 of a 17 oz cake, about 80g) contains approximately 257 calories. A larger NLEA serving (125g) has about 401 calories. Restaurant slices are often 150 to 175g, which can put you at 480 to 560 calories or more, depending on toppings.
Is cheesecake good for weight loss?
Cheesecake is not good for weight loss. It is calorie-dense (321 cal per 100g), high in sugar, and low in protein, which means it does not keep you full. However, a single planned slice (257 calories) can fit into a calorie deficit if tracked carefully. The issue is portion size: restaurant slices are often 2 to 3 times the standard serving.
How much protein in cheesecake?
Cheesecake has 5.5g of protein per 100g and about 4.4g per 80g slice. This is very low relative to the calories. Cheesecake is not a useful protein source. If you want a high-protein dessert option, Greek yogurt with fruit is a much better choice.
How many carbs in cheesecake?
A single 80g slice of cheesecake contains about 20.4g of carbs, including 17.4g of sugar. Per 100g, cheesecake has 25.5g of carbs and 21.8g of sugar. Most of the carbs come from added sugar in the filling and the sweetened graham cracker crust.
Can I eat cheesecake while cutting?
You can eat one slice of cheesecake while cutting if it fits within your daily calorie budget. At roughly 257 calories per slice, it is not budget-busting. The challenge is that it provides no protein, no fiber, and limited satiety, so it can leave you hungrier later. Plan it as a treat, not as a regular meal component.
Is cheesecake high in fat?
Yes. Cheesecake contains 22.5g of fat per 100g, with 9.9g being saturated fat. An 80g slice has 18g of fat and 7.9g of saturated fat. The fat comes from cream cheese and eggs. This high fat content contributes significantly to the calorie density of cheesecake.
