If you are older than 22, there is no amount of exercise that can overcome a poor diet.

I walk two miles, five days a week.
I ride a Spinner bike with the tension cranked up for 30-40 minutes a day, good cardio, sweats, etc.,

Need something to get this belly down some more.

What do you recommend?

I am 68 years old.
I used to jog but had feet issues years ago and switched to walking.
Which I've done for years. Many years. Five or six days a week
Two months ago, I added the Spinner resistance bike. I use moderate resistance to get the heart going and I ride 30-40 minutes, five or six days a week.

I am 6 feet 2 inches tall.
I started at 285 lbs. last Christmas, so seven months.
I've lost 30 lbs. I'm stuck at 255.

My shirt size has gone down one size from XXL to XL, pants from 42 to 40. Belts are longer these days, lol.

Diet is basic low carb. Meats - beef, chicken, pork, fish and lamb, eggs, fresh vegetables - squash, beans, avocados, onions, cauliflower, okra, salads, berries, cantaloupes, nuts, cheeses. one small apple a day, an occasional low carb tortilla or slice of low or no carb "bread". I eat some "keto" snacks but not much.

cocktails - couple times a week. A shot of Tequila with soda with a lime twist. Three or four. No beer, no regular soft drinks ever.

Light breakfast, sugar free yogurt and fruit or bacon and eggs, etc.
Main meal is at about 2 p.m. Grilled salmon, sauteed vegetables and salad, for example.
Only light snacks in the evening, cheese, sliced turkey or beef jerky, nuts, strawberries, keto snacks a little.

Sleep seven or eight hours.
I stay active every day, outdoor sports (clays and skeet), bass fishing, yard work - started using a push mower more then a rider, home chores etc.

That's pretty much it.

Two months ago, I added the Spinner resistance bike. I use moderate resistance to get the heart going and I ride 30-40 minutes, five or six days a week. Several factors you can play with. Your body will adapt quickly to the same regimen after about 2-3 weeks. Vary distance and time on your walks and alter the routes. Same with the spin bike. Rather than ride with the same resistance stand up and pedal with increased resistance for 10-15 seconds. Think pedaling uphill then back the resistance off and sit back down and pedal faster for 2-3 minutes. Lots of variables there at your disposable. Keeps it from being boring too.

I've lost 30 lbs. I'm stuck at 255. This is incredible progress and weight that will stay off. 2 - 2.5#/ week of loss is considered 'healthy'. Weight loss comes from 3 areas - muscle tissue, fat tissue, and water. Mitigating muscle loss after 50 is the trick. Protein helps but timing is more helpful. After you walk or have done a session on the bike eat a snack - 3:1 ratio of protein to carb. Chocolate milk is one of the easiest (and best) recovery drinks.

My shirt size has gone down one size from XXL to XL, pants from 42 to 40. Belts are longer these days, lol. Again this is a bigger measure than the scale weight. Inch loss = progress. Muscle does weigh more than fat so again as you lose down further inch loss becomes a greater marker.

When I worked with dietitians I was surprised by how many calories are in alcohol. Cutting out 1 drink a week can pay big dividends. Hydration is key too as alcohol has a diuretic effect. Water is your friend. It can be tap, sparkling, flavored, or from a garden hose but the key is to drink it.

Light breakfast, sugar free yogurt and fruit or bacon and eggs, etc.

Only light snacks in the evening, cheese, sliced turkey or beef jerky, nuts, strawberries, keto snacks a little. I have been surprised the older I get how sensitive my system is to eating after 7-8 p.m. regardless of what time I go to bed. I try not to eat anything 2 hours before bed if possible. I always wake up hungry but it forces me to drink water 1st thing and eat protein of some form.

Keep moving and fueling. You are doing great and probably feeling better than 30# ago!.

Bought three new, smaller shirts today. What a great feeling.
